Project description:To compare the splenic macrophages between SIRPα-knockout mice and WT mice, we performed a complete transcript profiling of the splenic red pulp macrophages from SIRPα-KO mice compared to WT mice using mRNA microarray as a discovery platform. SIRPα-KO mice and WT mice were kept under the same condition. Macrophages were isolated from spleen red pulp of SIRPα-KO mice and WT mice. RNA was then isolated from the same number of freshly isolated macrophages.
Project description:To investigate the roles of Klf3 in B lymphopoiesis, CD19+ B cells were sorted from the spleens of WT and Klf3 KO mice (Molecular and Cellular Biology (2008); 28:3967–3978). Following RNA extraction, gene expression was compared in WT and Klf3 KO CD19+splenic B cells using Affymetrix microarrays.

Project description:The experiment elucidates the development of splenic B- and T lymphocytes in the absence of a vital gene. For this purpose, spleen cells of 5 wild type and 5 full knock-out mice were depleted of red blood cells and prepared for 10x single cell RNA-Seq sequencing. The library was prepared according to the manufacturers instructions.
Project description:Tristetraprolin (TTP) binds to specific AU-rich elements in the 3'UTR of certain transcripts and regulates post-transcriptional gene expression by increasing the rate of mRNA turnover. In this study, we evaluated the effects of TTP deficiency on the overall gene expression of spleen tissue, in order to discover tissue specific targets of TTP under normal physiologic conditions. We utilized "Triple KO" (Zfp36-/-/TNFR1-/-/TNFR2-/-) mice that are deficient in TTP and two TNF receptors and compared the transcriptomic changes to "Double KO" (TNFR1-/-/TNFR2-/-) and WT mice. Spleen mRNA from four WT, four "Double KO", and four "Triple mice" was subjected to RNA-Seq in two phases. All the animals used in this study were males between the ages of 12-14 weeks and were on a mixed (75% C57BL/6NTac, 25% 129/SVEV) background. Examination of splenic gene expression difference between "Triple KO"-WT and "double KO"-WT data sets
Project description:GFI1 is a transcription factor known to be essential for hematopoiesis and lymphoid cell generation. We have recently found that gamma delta T cells express GFI1 and its absence can impact gamma delta T cell formation. In order to identify how the lack of GFI1 can affect the development of thegamma delta T cell subsets, we have performed a single cell sequencing approach using 10X genomics scRNAseq on splenic gamma delta T cells, thymic gamma delta T cells and a pool of thymic DN1-2-3 (DN) cells from WT and GFI1 KO mice. The sc RNA-seq highlighted differential transcriptomic changes between WT and GFI1 KO cells showing enrichment or absence of specific subsets of gamma delta cells and their thymic progenitors.
