We evaluated different respiratory mucosa immunization protocols that included the nasal administration of Lactococcus lactis-pneumococcal protective protein A (PppA) live, inactivated, and in association with a probiotic (Lc) to young mice. The animals that received Lc by the oral and nasal route presented the highest levels of immunoglobulin (Ig)A and IgG anti-PppA antibodies in bronchoalveolar lavages (BAL) and IgG in serum, which no doubt contributed to the protection against infection. However,

only the groups that received the live and inactivated vaccine associated RG7204 ic50 with the oral administration of the probiotic were able to prevent lung colonization by S. pneumoniae serotypes 3 and 14 in a respiratory infection model. This would be related to a preferential stimulation of the T helper type 1 (Th1) cells at local and systemic levels and with a moderate Th2 and Th17 response, shown by the cytokine profile induced in BAL and by the results of the IgG1/IgG2a ratio at local and systemic levels. Nasal immunization with the inactivated recombinant strain associated with oral Lc administration was able to stimulate the specific cellular and humoral immune response and afford protection against the challenge with the two S. pneumoniae serotypes. The results obtained show the probiotic-inactivated vaccine

association as a valuable alternative for application to human health, especially in at-risk populations, and are the first report of a safe and effective immunization BI 6727 order strategy using an inactivated recombinant strain. Streptococcus pneumoniae is an important respiratory pathogen with

high incidence in both developed and developing countries. Pneumococcal disease implies a significant economic burden to health care systems in Latin America [1]. Defence against pneumococcal infection involves innate and adaptive immune responses, and the control of these infections involves protective adaptive immunity through vaccine administration. However, pneumococcal vaccines available Galactosylceramidase at present do not constitute a definitive solution to this important health problem. This is because, while pneumococcal polysaccharide vaccines (PPV) have the potential to prevent disease and death, the degree of protection that they offer against different serotypes and within different populations is uncertain. In addition, while the new conjugate vaccines have shown effectiveness in young children, they do not represent a definitive solution. Protecting against those vaccine strains would give other pneumococcal strains the opportunity to cause infection and the impact of a pneumococcal vaccination programme would be reduced if serotype replacement were significant [2,3]. Moreover, the high cost of conjugate vaccines is one of the main reasons for the search for better immunization strategies against S. pneumoniae.

The individual PD20FEV1 × 10 was then used for the

subsequent Segmental Allergen Provocation (SAP). Inhaled and segmental allergen challenges were separated by at least 4 weeks. Bronchoscopy was performed as previously described [29, 42]. A volume of 2.5 ml of 0.9% saline was instilled into the anterior basal segment of the left lower lobe (B8 left) and one of the segments of the lingula (B4 or B5 left). Allergen diluted in 2.5 ml of saline was instilled into the anterior basal segment of the right lower lobe (B8 right) and the medial or lateral segment of the right middle lobe (B4 or B5 right). After 10 min, Selleckchem Stem Cell Compound Library bronchoalveolar lavage was performed in the anterior basal segments of the right and left lower lobes. Patients were re-bronchoscoped Protease Inhibitor Library cost at different time points: In the first group, the second lavage was performed after 18 h in segments B4 or B5 right and left. Some of these patients also participated in the second part of the trial. This second group was lavaged 10 min and 42 h after segmental allergen challenge (Table 1). In the third arm of the trial, four patients were

lavaged 10 min and 162 h after allergen challenge. In patients who participated repeatedly the segmental allergen challenges were separated by at least six months. In all patients, peripheral blood was taken before bronchoscopy. From seven healthy subjects and seven patients with allergic asthma, 250-ml whole blood was drawn and mixed well with heparin. Cell subtypes were separated by Ficoll centrifugation. PBMC-CD14+ were harvested, and after washing and counting monocytes were separated via immunomagnetic Amisulpride separation by AutoMACS system (Miltenyi Biotec GmbH, Germany) after labelling with CD14 antibody (Miltenyi Biotec GmbH). CD14+

monocytes were washed; purification was controlled by flow-cytometry (94–98% purified monocytes, contamination with lymphocytes was <2%), and 5 × 105 cells per well were cultured in 1 ml RPMI 1640 medium (GIBCO, Paisley, Scotland, UK) + 10% FCS (Seromed, Berlin, Germany) + 1% penicillin/streptomycin (Biochrom AG, Berlin, Germany) at 37 °C and 5% CO2. Cells differentiated to macrophages in about 5 days. Medium was exchanged every 2 days. The above-mentioned PBMC-CD14+ cells (5 × 105 cells in 1 ml) were stimulated with either human IL-17 (50 ng/ml), LPS (10 ng/ml), leukotriene D4 (LTD4) (10−11 M) or a combination of LPS and LTD4 for a duration of 6, 12 and 24 h. Cells were also stimulated with LTD4 in the presence of the leukotriene antagonist Montelukast. LTD4 was added to cell cultures 30 min after stimulation with Montelukast (10−11 M), and cultures were incubated for 6, 12 and 24 h. Cell culture supernatants were stored at −20 °C until sCD14 measurement with an ELISA kit (IBL Hamburg, Germany) according to the manufacturer’s instructions. Data were analysed by SPSS software package. Results are reported as median (range) or as single values and median (Figs. 2–5).

Indeed, statistics show that CVD mortality

rates among organ transplant recipients are up to 10-fold those in the non-transplant population.19–23 While dyslipidaemia and CVD are often present at the time of transplantation, immunosuppressive medications (such as calcineurin inhibitors, sirolimus and corticosteroids), lifestyle factors and post-transplant renal function are also implicated in abnormal serum lipid levels and CVD risk post-transplantation.24–30 Guidelines for the Osimertinib supplier management of dyslipidaemias in the general population make recommendations on diet and other aspects of lifestyle including exercise, body weight, alcohol consumption and smoking.1,2,5,31–33 The objective of this guideline is to ensure that appropriate dietary interventions are used to prevent and manage dyslipidaemia in adult kidney transplant recipients. Relevant reviews and studies were obtained from the sources below and reference lists of nephrology textbooks, review articles and relevant trials were also used to locate studies. Searches were limited to studies on humans; adult kidney transplant recipients; single organ transplants and to studies published in English. Unpublished studies were not reviewed. Databases searched: MeSH terms and text words for kidney

transplantation were combined with MeSH terms and text words for both dyslipidaemia and dietary interventions. Dietary fish oil and fish oil supplements were selleck compound library Clostridium perfringens alpha toxin not included in the search as this literature review has been undertaken previously. MEDLINE – 1966 to week 1, September 2006; EMBASE – 1980 to week, 1 September 2006; the Cochrane Renal Group Specialised Register of Randomised

Controlled Trials. Date of searches: 22 September 2006. There are few published studies of satisfactory quality examining the safety and efficacy of specific dietary interventions in the management of dyslipidaemia in kidney transplant recipients. Level I/II: There are no randomized controlled trials investigating the efficacy of nutritional interventions for treating dyslipidaemia in kidney transplant recipients. Level III: There is one study of satisfactory quality providing level III-1 evidence that a modified Mediterranean-style diet (rich in high fibre, low glycaemic index carbohydrates; vegetables; vitamin E-rich foods; and sources of monounsaturated fatty acids) may lower serum total cholesterol and triglycerides in kidney transplant recipients.34 Level IV: There is one study providing level IV evidence that a diet low in carbohydrate and high in polyunsaturated fat may be effective in normalizing HDL-cholesterol and may lead to weight loss in adult kidney transplant recipients.35 There is one level IV (pre-test, post-test study) of satisfactory quality investigating the safety and efficacy of a modified version of the American Heart Association (AHA) Step One diet.

2 and supplementary Fig. S2). Up-regulation of Gr-1 is not part of the maturation process demonstrated in Fig. 7, and although a role in limiting T-cell proliferation is not ruled out by this experiment, the soluble mediators NO and PGE2 together are sufficient to restrict T-cell proliferation. Finally,

Silmitasertib mouse it was striking that despite the strong phenotype of TNFR1−/− Mϕin vitro and in vivo, we could restore near normal inhibitory function by treating with a combination of soluble mediators (Fig. 7). This result illustrates on the one hand the emergent properties that multiple signals can have on cell function and on the other hand the many levels of redundancy that are inherent in Mϕ responses. This redundancy complicates the analysis of function learn more in vitro and in vivo, but it is also likely to produce immune responses that in the wild are more robust and less

susceptible to a single targeted attack by a pathogen. This work was carried out with support from the National Eye Research Centre. The authors declare no competing interests. Figure S1. WT BM-Mφ were prepared as described in the methods section. Cells were then stained with antibodies against CD11b, CD31, F4/80, and Gr-1. Plot A shows F4/80 and CD11b expression by naïve BM-Mφ. Plots B and C show CD31 and Gr- 1 expression naïve BM-Mφ (black lines) compared with isotype controls (grey filled). Figure S2. WT or TNFR1−/− BM-Mφ were co-cultured with OT-II T cells in the lower

chambers of 0.22 μm transwells in the presence of 100 μg/ml OVA peptide. Equal numbers of either WT or TNFR1−/− BM-Mφ were added to the top chamber. After 72 hr, from the both chambers were harvested separately and stained with antibodies against CD11b and Gr-1 for flow cytometric analysis. Plots show Gr-1 expression of CD11b+ cells, with Mφ from the top chamber (red lines) and those from the lower chamber (blue lines). Figure S3. WT or TNFR1−/− BM-Mφ were co-cultured with OT-II T cells in the presence of 100 μg/ml OVA peptide for 72 hr. L-NMMA or SNAP was added at the indicated concentrations. T cell proliferation was measured over the final 8 hr of culture. NO production was measured in the culture Bupivacaine supernatant. Plots show the effect of addition of L-NMMA or SNAP on NO production and proliferation on cocultures containing WT (black lines) or TNFR1−/− (grey lines) Mφ, as compared with control co-cultures in which Mφ alone were cultured. “
“M protein is an important virulence determinant in Streptococcus pyogenes, but the amounts of M protein in various strains of the species remain to be elucidated. To assess the amount of M protein in strains of each emm genotype, dot blot analysis was performed on 141 clinically isolated strains. Among the cell membrane-associated proteins, M protein was present in greater quantities in the emm1, 3, and 6 strains than in the other emm strains.

Antimicrobial agents used included ampicillin, gentamicin, and imipenem INCB018424 datasheet (MSD, Tokyo, Japan), clindamycin and linezolid (Pfizer Japan,

Tokyo, Japan), dripenem and vancomycin (Shionogi Pharmaceutical, Osaka, Japan), levofloxacin (Daiichi-Sankyo, Tokyo, Japan), and meropenem (Dainippon Sumitomo Pharma, Osaka, Japan). MICs were determined using an agar dilution method as described by the CLSI (CLSI 2009). Susceptibility testing was performed on Mueller-Hinton agar (Nippon Becton Dickinson) in accordance with the manufacturer’s instructions. MIC breakpoints for B. cereus were not defined by CLSI. The MicroScan broth microdilution system (Siemens Healthcare Diagnostics, Tokyo, Japan) was employed for susceptibility testing. For the MicroScan system, a single fresh colony was used to prepare an inoculum selleck chemical equivalent to a turbidity of 0.5 McFarland standard in distilled water containing a detergent (Pluronic). The MicroScan Pos Breakpoint Combo Panel Type 3.2A panel containing Mueller-Hinton

broth filled with inoculum diluted 250-fold was incubated at 35 °C under aerobic conditions and was read visually after 18 h of incubation. Then the results were compared with the agar dilution susceptibility test (reference) results. ‘Essential agreement’ was defined as agreement within ± 2 log2 dilutions between the MicroScan broth microdilution test and the reference agar dilution susceptibility test. Etest susceptibility testing was performed on Mueller-Hinton agar in accordance with the Etest

technical guide (AB Biodisk, Solna, Sweden). ‘Essential agreement’ was defined as agreement within ± 2 log2 dilutions between the Etest and the reference agar dilution susceptibility test. Paired data were compared using Fisher’s exact test using jstat for Windows version 10.0 (http://www8.ocn.ne.jp/˜jstat/) and probability (P) why values of less than 0.05 were considered significant. All 26 isolates were identified phenotypically as B. cereus group, i.e. facultatively anaerobic, endospore-forming, gram-positive rods that were positive for the egg yolk reaction and utilized d-trehalose (Logan et al., 2007). None of the 26 isolates carried the emetic toxin (ces) gene, the NRPS gene or the nheBC gene. The genes encoding enterotoxins (EntFM and EntS) and the piplc gene were commonly found in the isolates. The profile of the other virulence genes in the 26 B. cereus isolates and ATCC14579 is shown in Table 2. The epidemiologic relations of the 26 isolates were analyzed by PFGE. The PFGE patterns of 24 isolates were different from each other, suggesting that these isolates were epidemiologically unrelated, while the other two isolates (strains 17 and 25) were related (Fig. 1). The susceptibilities (MIC range, MIC50 and MIC90) of the 26 isolates determined using the agar dilution (reference) method are shown in Table 3.

7–12 Other observations underline the need to study the differences between human

and NHP immune responses: a humanized anti-CD28 monoclonal superagonist antibody caused severe side-effects in a phase 1 clinical trial;13 it induced a delayed and sustained Ca2+-influx in human CD4+ T cells, but not in CD4+ T cells from NHPs.14 Any experimental study of cellular, adaptive immune responses addresses also T-cell homeostasis, the active and dynamic process by which immune cells mature traffic and produce cytokines upon activation. Key elements of the analysis of adaptive cellular immune responses are (i) T-cell subsets (CD4/CD8, CD8αα+ memory T cells) in concert with differentiation and homing markers (CD45RA, CCR7, CD28, CD27, CD62L),15 cytotoxicity (measure of CD107a) and cytokine production (polyfunctionality);16 (ii) regulatory Roxadustat chemical structure T cells (Tregs);17 and (iii) the response to interleukin-7 (IL-7), a key cytokine for T-cell survival, homeostasis and T-cell memory.18 T-cell compartment composition and phenotype has been studied selleck chemical previously in rhesus macaques19,20

with a limited panel of immune markers. Different combinations of immune markers were used in these studies to define memory and effector T-cell compartments in rhesus monkey.21 To our knowledge, the current report analyses for the first time the simultaneous expression of CD45RA, CCR7, CD27 and CD28 in T-cell subsets

in healthy rhesus monkeys. We took advantage of a high-content, multicolour flow cytometry to assess the distribution of immune cells in peripheral blood mononuclear cells (PBMCs) from female rhesus monkeys (defined by expression of CD45RA, CCR7, CD28, CD27, CD107a, IL-7 receptor α-chain), to compare cytokine [IL-2, interferon-γ (IFN-γ) and tumour necrosis factor-α (TNF-α)] production in T-cell subsets, IL-7-induced signal transducer and activator of transcription 5 (STAT-5) phosphorylation, and Treg frequencies. Peripheral blood was obtained from 16 healthy human donors (19–66 years, median 31 years) from the Blood Bank (Ethical Permit DNR 00-097). Peripheral blood was obtained from 27 female rhesus macaques (Macaca Benzatropine mulatta) of Chinese origin with an age range between 3 and 4 years housed in the Astrid Fagraeus laboratory at the Swedish Institute for Infectious Disease Control. Housing of the animals and care procedures were in compliance with the provisions and general guidelines of the Swedish Animal Welfare Agency, the Local Ethical Committee responsible for Animal Experiments approved all procedures (protocol DNR238/2006-54). The PBMCs were isolated from freshly obtained, heparinized peripheral blood by Ficoll–Hypaque density gradient centrifugation. Immune marker analysis was performed on freshly isolated PBMCs by a standard Ficoll procedure from heparinized blood samples.

Given the basic assumption that ethnic groups residing in Arctic areas have more general and local cold exposure than ethnic groups who reside in

tropical areas, this may have resulted in genetic or functional adaptations over the course of their ancestry. Therefore, it is worthwhile to look at racial differences in local responses to cold. Many of the early studies on cold tolerance employed a cross-sectional approach comparing nonadapted controls with a population living or working in cold environments. Alternatively, if the control group could be drawn from individuals of similar ethnicity, it check details can be assumed that the primary difference is in environmental exposure rather than in genetic differences. In support of CIVD being a protective response, humans living in or native to a cold environment seems to have enhanced CIVD, marked by shortened onset times and higher amplitudes, compared with tropical or nonadapted

ICG-001 order individuals. For example, Arctic natives such as Inuit and Lapps generally have higher mean finger temperatures and CIVD responses compared with control populations from more temperate regions [12,45,56]. Negroid subjects are known to have lower finger skin temperatures during CIVD than Caucasians [54]. Leblanc et al. [47] observed no differences in skin thickness or cell size between skin biopsies of fishermen and controls; however, the fishing group had a greater number Fenbendazole of mast cells in the skin. Mast cells are present in several types of tissues, and contain many granules rich in histamine; H2 histamine receptors are located in smooth muscle cells, and cause a strong vasodilation when stimulated. Again, it is not known if these differences were inherited or acquired. Some ethnic groups continued to be exposed to local and whole body cold for centuries, like the Inuit, whereas other ethnic groups were mainly exposed to heat. Early population-based research demonstrated that Arctic residents have a better CIVD response than non-Arctic residents [12,45,56]. Even though the fingers

are relatively shorter and thicker for people living close to the poles [2,48], providing less biophysical [62] surface area for heat exchange, the fingers nevertheless seem to be able to lose more heat to the environment when exposed to severe cold. Locations where CIVD is observed coincide with the presence of AVAs in the human skin [7]. These AVAs contain alpha-2 receptors and are under powerful sympathetic control; when CIVD occurs, the strong muscle wall of the AVA suddenly relaxes. Hale and Burch [39] reported that AVAs form when there is a higher need for blood flow in the finger. However, the magnitude of this response is very small: 95% of the AVAs remain unchanged and the stimulus for AVA formation has to be severe, for instance, strong ischemia followed by hyperemia.

“To assess the effectiveness of supine/standing urinalysis for differential diagnosis of left renal vein entrapment syndrome (LRVES) combined with or without glomerulopathy. The enrolled patients with abnormal urinalysis and LRVES demonstrated by Doppler sonography were guided to perform a supine/standing urinalysis. Fifty-two patients were enrolled. Most of them were adolescents (aged 14–29 years, 73.1%) and with low body mass index (BMI, mean BMI, 19.8 ± 2.4 kg/m2). Seventeen cases (32.7%) manifested orthostatic urine abnormalities (OUA, proteinuria and/or haematuria show negative in supine while positive after 15 min standing), two patients who had undergone renal biopsies both showed no evidence of kidney lesions, another GS-1101 concentration two patients were changed from abnormal to normal urinalysis after weight gain. The remaining 35 cases (67.3%) manifested

non-orthostatic urine abnormalities (NOUA, proteinuria and/or haematuria show positive both in supine and standing), 15 patients had undergone renal biopsies and showed different degrees of glomerulopathy. After prednisone/immunosuppression therapy, four patients with glomerulonephritis were changed from the NOUA to the OUA classification. Statistics analyses showed that serum total protein and albumin

levels were significantly lower (P = 0.028, 0.007, respectively) and urinary protein was significantly higher (P = 0.007) in the NOUA group than in the OUA group. After the indication of LRVES by ultrasound, patients with OUA likely have only LRVES, while patients with NOUA likely also have glomerulopathy. Supine/standing urinalysis combined with Doppler sonography can be helpful for differential diagnosis of LRVES combined with or without glomerulopathy. “
“Myeloma cast nephropathy contributes to high morbidity Arachidonate 15-lipoxygenase and early mortality associated with the development of end-stage renal disease. Treatment with extended high cut-off haemodialysis coupled with novel anti-myeloma therapies enables significant reduction of serum-free light chains and has been shown to improve renal outcomes. In this case series, medical records of 6 patients who received high cut-off haemodialysis for biopsy-proven cast nephropathy were retrospectively reviewed. Patients received a total of 344 hours of high cut-off haemodialysis and concurrent chemotherapy. Only 50% became dialysis independent following treatment. One patient who achieved sustained remission remained dialysis dependent.

In addition, Rorγt+ ILC numbers were also reduced upon specific deletion of AhR in Rorγt-expressing cells (including ILCs) [[56]]. Together these data indicate that the effects of AhR-deficiency on

Rorγt+ ILCs are cell intrinsic. Interestingly, the reduction of Rorγt+ ILC numbers, induced by ablation of AhR, was observed only after birth. see more During fetal development, and early after birth, the ILC22 numbers in AhR-deficient mice are comparable to those in wild type mice, indicating that AhR is not required for development of these cells [[54]]. However, after weaning, the numbers of Rorγt+ ILCs in AhR-deficient mice steadily decrease [[54]]. Maintenance of ILC numbers is not a consequence of AhR activation by products of colonizing microbiota, because the difference in ILC22 numbers between wt and AhR-deficient animals is not affected by treatment with a mix of antibiotics [[54]]. Also, the observation that germ-free animals do not show reductions in gut residing Rorγt+ ILC numbers [[55, 57]] is consistent with the notion

that products from commensals are not required for the maintenance of these cells. It is controversial whether dietary products are the AhR ligands responsible for the maintenance of gut-residing Rorγt+ ILCs, as observed for IELs [[53]]. In one study, it was found that mice fed with a diet free of AhR-binding phytochemicals showed decreased numbers of Rorγt+ ILCs, causing a lack of CPs and Suplatast tosilate ILFs [[55]]. Addition of indole-3-carbinol, a dietary product, restored the Rorγt+ ILC numbers [[55]]. Another study, however, suggested that endogenous Small molecule library solubility dmso AhR ligands, including the tryptophane catabolite kynurenine, were potent regulators of Rorγt+ ILC maintenance as removal of dietary AhR ligands in that study did not disturb Rorγt+ ILC homeostasis and function [[56]]. The differences may be due to different types of controlled diets used by the different groups.

Further experiments should aim to resolve these discrepancies. The mechanisms by which AhR controls Rorγt+ cell numbers are not fully understood. Microarray analysis of Rorγt+ cells from wt and AhR-deficient mice suggested that Notch 1 is a downstream target of AhR [[56]]. Consistent with this, administration by gavage of the toxin TCCD (2,3,7,8-tetrachlorodibenzo-p-dioxin) resulted in the upregulation of Notch1 and Notch2 in gut Rorγt+ ILCs. Evidence for a role of Notch in AhR-mediated maintenance of Rorγt+ ILCs was provided by the observation that mice deficient for RBP-Jk, an essential partner of Notch, showed substantially reduced numbers of NKp46-expressing Rorγt+ ILCs and, although less prominently, of CD4+ Rorγt+ ILCs (LTi cells) also [[56]]. However, there were differences between the AhR- and RBP-Jk-deficient mice, in that in the latter, cryptopatches and ILFs were largely intact, whereas they were greatly reduced in AhR-deficient mice [[56]].

2 and 3 and Supporting Information Fig. 4 and 7). In case of the 7AAD-based viability stain, the autofluorescence+ cells/debris were eliminated from the viable population due to their 7AAD/PE-Cy5.5-like autofluorescence properties. For intracellular anti-BrdU and Ki67 stainings the BrdU Flow Kit (BD Bioscience) was applied according to the manufacturer’s recommendations together with the 7AAD staining for the total cellular DNA content. The CD115 intracellular staining was performed with cells

fixed with 4% paraformaldehyde and permeabilized with 0.2% saponin in PBS. In the intracellular stainings, BAY 80-6946 datasheet viable cells are defined as scatter pregated to remove cellular debris. For the analysis of the level of marker expression, delta median fluorescence intensity (ΔMFI) was calculated according to the formula ΔMFI = MFI(Marker) − MFI(Isotype), where MFI(Marker) and MFI(Isotype) refer to the stainings of the same sample with the specific antibody and the isotype control antibody, respectively. The antibodies used are listed in Supporting Information Table 2. Flow cytometry analysis

was carried out with FACS Calibur and FACS Fortessa (BD Bioscience) devices and FlowJo Software (Tree Star, Ashland, OR). Preparation of whole cell lysates from tumor tissue and RNA extraction and cDNA synthesis from whole tumors, tumor cultures, and sorted cells were described elsewhere [41]. mRNA expression levels were analyzed either with a TaqMan or an Eva MK-8669 datasheet Green basing protocol as reported in [4]. The amplification of TATA-Box Binding Protein (TBP or Tbp) mRNA was used to normalize expression levels for both Casein kinase 1 methods. Expression

levels for the gene of interest are represented as the relative log2 amounts using the formula Egene = CtTbp − Ctgene. The sequences of primers with the corresponding amplification method are listed in Supporting Information Table 3. NT2.5 cells (provided by Dr. Elisabeth Jaffee), tumor, and BM single-cell suspensions were cultured in RPMI 1640 supplemented with 10% FCS, l-glutamine, 1 mM sodium pyruvate, 1 mM HEPES, 100 IU/mL penicillin, 100 μg/mL streptomycin, and 50 μg/mL gentamycin and 50 μM β-ME. Tumor cell culture conditioned medium was obtained from 24 h or 3 day cultures seeded at 1 × 106 cell/mL density and filtered with a 0.22 μm PES syringe filter to exclude any contamination with tumor cells. Levels of CSF1 in tumor cell culture conditioned media (24 h primary tumor culture) and whole cell tumor lysates (2-week-old tumors) were determined with the murine M-CSF standard ELISA development kit (Peprotech, Rocky Hill, NJ) according to the manufacturer’s protocol. The ChIP was performed essentially as described [42] with minor modifications. In brief, NT2.5 cells were grown to 80% confluence and stimulated for 30 min with 20 ng/mL IFN-γ (Peprotech) and/or 50 ng/mL TNF-α (Peprotech) or left untreated.
