Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from bone marrow derived macrophages upon exposure to 20 ng/ml of IL-4 for 18 hours. Bone marrow derived macrophages were stimulated with the Th2 cytokine IL-4, for RNA extraction and hybridization on Affymetrix microarrays.
Project description:ATAC-seq profiling of Nfat5 KO and wild type macrophages derived from bone marrow (primary cells), treated or not with Lipopolysaccharide (LPS).
Project description:To provide a global perspective on the relationships between macrophage activation programs and to understand how certain pathogens circumvent them, we used transcriptional profiling by genome wide microarray analysis to compare the responses of mouse macrophages following exposure to the intracellular parasites Trypanosoma cruzi and Leishmania mexicana, the bacterial product lipopolysaccharide (LPS), and the cytokines IFNG, TNF, IFNB, IL-4, IL-10, and IL-17. We found that LPS induced a classical activation state that resembled macrophage stimulation by the Th1 cytokines IFNG and TNF. However, infection by the protozoan pathogen Leishmania mexicana produced so few transcriptional changes that the infected macrophages were almost indistinguishable from uninfected cells. Trypanosoma cruzi activated macrophages produced a transcriptional signature characterized by the induction of interferon-stimulated genes by 24 h post-infection. Despite this delayed IFN response by T. cruzi, the transcriptional response of macrophages infected by the kinetoplastid pathogens more closely resembled the transcriptional response of macrophages stimulated by the cytokines IL-4, IL-10, and IL-17 than macrophages stimulated by Th1 cytokines. Keywords: Bone marrow macrophage response to intracellular parasites and cytokines We analyzed a series MEEBO arrays on which were hybed RNA amplified from bone marrow-derived macrophages from C57BL/6 mice. Macrophages infected with L. mexicana or T. cruzi or stimulated by LPS, IFNG, IL-4, IL-10, TNF, IFNB, or IL-17 were compared to one another as well as to uninfected, unstimulated control macrophages. All experiments were performed over a 24 h timecourse with timepoints taken at 2 h, 6 h, 12 h, and 24 h.
Project description:We report the genome-wide RNA sequencing analysis in Il10-/- bone marrow-derived macrophages (BMDMs) stimulated by lipopolysaccharide (LPS) where IL-10 effect in macrophage inflammatory response was examined in IL-10-deficient BMDMs upon LPS stimulation with addition of exogenous IL-10.
