Project description:Commensal bacteria shape the gut immune system. Colonization bacteria increase the frequency of regulatory T cells, however, the molecular mechanisms are not yet known. To reveal the mechanism, we isolated naïve CD4+ T cells from the spleen of C57BL/6 mice and cultured the cells under Treg-inducing condition culture in the presence or absence of butyrate, a metabolite produced by commensal bacteria. Naïve T cells were isolated from spleen and were cultured in the presence of IL-2, TGF-beta and in the presence or absene of Butyrate. RNA was extracted at Day 2.

Project description:To investigate the inhibition effect of DYRK1B kinase function on human naïve CD4+ T cell differetionation which stimulated under Treg polarizing condition for 24 hours.
Project description:To investigate the function of Neuropilin-1 (NRP-1) in Foxp3+ regulatory T (Treg) cell stability and function, we cultured naïve CD4+ T cells under induced Treg cell (iTreg)-differentiating condition. We then flow sorted NRP-1+ and NRP-1- iTreg cells and performed gene expression profiling analysis.
Project description:To investigate that Tubastain A, a HDAC6 inhibitor, has effect on early stage of iTreg differentiation, we treated naïve CD4+ T cells with DMSO (vehicle control) or 10 uM Tubastatin A and cultured the cells under Treg-skewing condition for 1 day. We then performed gene expression profiling analysis using data from RNA-seq of 2 different samples.
Project description:We determined differentially regulated gene expression profile in CD4 naïve T cells cultured in presence or absence of Th17 inducing cytokines (IL23+IL1β) and anti-CD28. We reported that CD28 costimulation induced Th17-suppressive gene signature.
Project description:miRNA expression profiling in highly purified murine CD4+ Tconv and Treg cells. FoxP3-GFP-hCre1a(high) reporter mice were used to separate both populations based on surface markers and presence or absence of GFP. Two-condition experiment, Tconv vs. Treg. Biological replicates: 1 Tconv, 1 Treg, purified from the same pooled mice. One replicate on 1 array.
