Comparison of naïve, postmitotic (CD44-lo/CD62L-hi) and effector (CD44-hi/CD62L-lo) CD8+ Tcells during BMT in GVHD mice

ABSTRACT: Naïve CD44-lo/CD62L-hi/CD8+ T cells from C3H.SW mice were compared to CD44-hi/CD82L-lo/CD8+ effector memory T cells and CD44-lo/CD62L-hi/CD8+ postmitotic T cells, using 3 biological replicates of each type of sample. The later two cells types were highly purified at day 14 after transplantation from GVHD B6/SJL mice receiving donor C3H.SW mouse-derived naive CD44-lo/CD62L-hi/CD8+ T cells and T cell-depleted bone marrow. Recipient mice had first been lethally irradiated at a dose of 10Gy in two fractions. This is a MHC-identical minor histocompatibility antigen-mismatched mouse GVHD model of human allogeneic hematopoietic stem cell transplantation. Naive T cell samples were from pools of 2 mice each, while effector memory and postmitotic T cell samples were purified from pools of T cells from 4 mice each. After RNA extraction and cleanup, biotin labeled cRNA was prepared from 600 ng total RNA, using two rounds of in vitro transcription, and hybridized to Affymetrix Mouse Genome 430A 2.0 arrays using standard techniques. Keywords: Cell type comparison

Generation and purification of Th1 and Th2 effector and memory CD4+ T cells

Project description:NaÃ¯ve CD4+ T cells were isolated from spleen of AND TcR transgenic/green fluorescence protein (GFP) transgenic mice (Kaye et al., Nature 1989;341:746, Wright et al, Blood 2001;97:2278) that recognize a peptide of pigeon cytochrome C in the context of I-Ek and express CD44lo, CD62Lhi, CD45RBhi, and CD25-. After 4 days in vitro stimulation with antigen presenting cells (APC) under either Th1 or Th2 condition, naÃ¯ve cells become Th1 or Th2 effector cells expressing CD44hi, CD62L lo, CD45RBhi, and CD25+. Additional 3 days culture in the absence of APC, those effector cells become rested expressing a phenotype similar to memory cells (CD44 hi, CD62L lo, CD45RB lo and CD25-). These rested effector cells were adaptively transferred into thymectomized, lethally irradiated, and T cell depleted bone marrow reconstituted mice and memory cells were isolated after 4-12 weeks by flow sort. Generation and purification of Th1 and Th2 effector and memory CD4+ T cells of 42 samples.

Expression data from sorted Id3-GFP hi Id2-YFP int and Id3-GFP lo Id2-YFP hi activated CD8 T cells

Project description:During an immune response, CD8 T cells fall along a gradient of memory potential, but the regulators of these fate decsisions are not well understood. We utlized Id3-GFP and Id2-YFP reporter mice to elucidate the role of Id3 and Id2 during early CD8 T cell differentiation by gene expression. Id3-GFP hi Id2-YFP int or Id3-GFP lo Id2-YFP hi OT-I cells were sorted into trizol at day 6 of VSV-OVA infection and analyzed by microarray

Mucosal CCL28 Chemokine Improves Protection against Genital Herpes through Mobilization of Antiviral Effector Memory CCR10+CD44+ CD62L-CD8+ T Cells and Memory CCR10+B220+CD27+ B Cells into the Infected Vaginal Mucosa

Project description:Four major mucosal-associated chemokines, CCL25, CCL28, CXCL14, and CXCL17, play an important role in protecting mucosal surfaces from infectious pathogens. However, their role in protection against genital herpes remains to be fully explored. The CCL28 is a chemoattractant for the CCR10 receptor-expressing immune cells and is produced homeostatically in the human vaginal mucosa (VM). In this study, we investigated the role of the CCL28/CCR10 chemokine axis in mobilizing protective antiviral B and T cell subsets into the VM site of herpes infection. We report a significant increase in the frequencies of HSV-specific memory CCR10+CD44+CD8+ T cells, expressing high levels of CCR10, in herpes-infected asymptomatic (ASYMP) women compared with symptomatic women. Similarly, a significant increase in the CCL28 chemokine (a ligand of CCR10), was detected in the VM of herpes-infected ASYMP C57BL/6 mice, associated with the mobilization of high frequencies of HSV-specific effector memory CCR10+CD44+CD62L-CD8+ TEM cells and memory CCR10+B220+CD27+ B cells in the VM of HSV-infected ASYMP mice. Inversely, compared with wild-type C57BL/6 mice, the CCL28 knockout (CCL28-/-) mice (1) appeared to be more susceptible to intravaginal infection and reinfection with HSV type 2, and (2) exhibited a significant decrease in the frequencies of HSV-specific effector memory CCR10+CD44+CD62L-CD8+ TEM cells and of memory CD27+B220+ B cells in the infected VM. These findings suggest a critical role of the CCL28/CCR10 chemokine axis in the mobilization of antiviral memory B and T cells within the VM to protect against genital herpes infection and disease.

Transcriptional profiling of CD4+ T cells activated in murine malaria.

Project description:CD4+ T cells are critical for defense against the Plasmodium parasites that cause malaria. To better understand CD4+ T cell effector mechanisms during malaria, we performed microarray analysis of CD4+ T cells from naïve and infected mice. Comparison of activated (CD44 hi CD62L lo) CD4+ T cells from infected mice to bulk CD4+ T cells from naïve mice revealed a subset of genes that were upregulated by infection with Plasmodium chabaudi. These results help generate a more complete picture of CD4+ T cell function in malaria.

CD62L expression marks a functionally distinct subset of memory B cells

Project description:The memory B cell response consists of phenotypically distinct subsets that differ in their ability to respond upon antigen re-encounter. However, the pathways regulating the development and function of memory B cell subsets are poorly understood. Here we show that CD62L and CD44 are progressively expressed on mouse memory B cells and identify transcriptionally and functionally distinct memory B cell subsets. Bcl6 is important in regulating memory B cell subset differentiation with overexpression of Bcl6 resulting in impaired CD62L+ memory B cell development. Bcl6 regulates memory B cell subset development through control of a network of genes, including Bcl2 and Zeb2. Overexpression of Zeb2 impairs the development of CD62L+ memory B cells. Importantly, CD62L is also differentially expressed on human memory B cells following SARS-CoV-2 vaccination and identifies phenotypically distinct populations. Together, these data indicate that CD62L expression marks functionally distinct memory B cell subsets.
