Project description:Primary non-expanded human T cell populations were isolated by leukapheresis from 10 healthy donors. Out of each donor > 95% pure CD4-positive Th cell and >95% pure regulatory T cell populations were purified. Two affymetrix exon arrays were hybridized from each donor both populations as resting, non-activated samples. In addition, samples were hybridized from each donor and both populations activated by anti-CD3/anti-CD28 treatment for 4hours and 16 hours.

Project description:Natural killer (NK) cells are innate lymphocytes important for early host defense against infectious pathogens and surveillance against malignant transformation. Resting murine NK cells regulate the translation of effector molecule mRNAs (e.g. granzyme B, GzmB) through unclear molecular mechanisms. MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate the translation of their mRNA targets, and are therefore candidates mediating this control process. While the expression and importance of miRNAs in T and B lymphocytes has been established, little is known about miRNAs in NK cells. Here, we utilized two next-generation sequencing (NGS) platforms to define the miRNA transcriptomes of resting and cytokine-activated primary murine NK cells, with confirmation by RT-qPCR and microarrays. We delineate a bioinformatics analysis pipeline that identified 302 known and 28 novel mature miRNAs from sequences obtained from NK cell small RNA libraries. These miRNAs are expressed over a broad range, exhibit isomiR complexity, and a subset is differentially expressed following cytokine-activation. Using this miRNA NGS data, miR-223 was identified as a mature miRNA present in resting NK cells with decreased expression following cytokine-activation. Further, we demonstrate that miR-223 specifically targets the 3’UTR of murine GzmB in vitro, indicating that this miRNA may contribute to control of GzmB translation in resting NK cells. Thus, the sequenced NK cell miRNA transcriptome provides a valuable framework for further elucidation of miRNA expression and function in NK cell biology. Illumina GA (SRR036363, SRR036364) and SOLiD (SRR036206, SRR036210) sequencing data have been submitted to the NCBI Sequence Read Archive (SRA). The study uses a custome made array to characterize miRNA of activated and resting murine splenic natural killer cells

Project description:CD4+ T cells (T helper cells) are cytokine-producing adaptive immune cells that activate or regulate the responses of different immune cells. They are known to play crucial roles in antibody class switching in B cells, neutrophil recruitment and activation of macrophages and CD8+ cytotoxic T cells. The activation and functional status of CD4+ T cells is important for adequate responses to pathogen infections but has also been associated with auto-immune disorders and survival in several cancers. In the current study, we carried out proteomic profiling of resting and activated primary human CD4+ T cells from healthy donors. In addition to identifying known markers of CD4+ T cell activation, we also identified protein kinases, protein phosphatases, and cytokines to be differentially expressed.
