Alopecia areata (AA) is a common autoimmune disease resulting from damage of the hair follicle by T cells. The immune pathways required for autoreactive T cell activation in AA are not defined limiting clinical development of rational targeted therapies. Genome-wide association studies (GWAS) implicated ligands for the NKG2D receptor (product of the KLRK1 gene) in disease pathogenesis. Here, we show that cytotoxic CD8(+)NKG2D(+) T cells are both necessary and sufficient for the induction of AA i ...[more]

Murine HIV-gagP24 CD8 T cells: bone marrow vs Lymph node

Project description:Transcriptional profiling to examine differences resulting from priming of virus-specific CD8 T cells in draining lymph node and in bone marrow, following intradermal injection of modified virus Ankara (MVA)-HIV gag. Transcriptional profiling of mouse pentamer H2kD-AMQMLKETI (HIV-gagP24) CD8 T cells from draining lymph nodes(LN) and bone marrow (BM ) 5 days following intradermal injection of MVA-HIV gag, and compared to naive (CD62L Hi CD44 int) CD8+ T cells from lymph node of naive mice (NTc).

scRNA/TCR-seq of CD8+CD44+ T cells from tumor draining lymph node and matched vitiligo-affected skin of MAV mice

Project description:Purpose: To identify the presence of endogenous tumor-specific TRM cells in LNs, scRNAseq was performed to identify populations of CD8 T cells with TRM transcriptional characteristics in DLNs. Methods: CD8+CD44+ T cells were sorted from DLN and skin of MAV mice and scRNA-seq in parallel with scTCR-seq was performed. Results: The twenty most expanded clonotypes identified in vitiligo-affected skin of these mice, eight matched to lymph nodes and strikingly, those lymph node clonotypes that had matches in skin mapped almost exclusively to the LN TRM cluster Conclusions: Endogenous tumor-specific CD8 T cells form TRM responses in tumor-draining LNs.

RNAseq analysis of mature thymic NKT cells and immature thymic DN1eP cells

Project description:We report the identification of immature thymic CD4(-),CD8(-) double-negative (DN)1e cells with the NKT cell lineage potential. We also analyzed the gene expression profiles of DN1e thymocytes compared with those of mature thymic NKT cell developmental stages termed NKT stage-1, 2, and -3, which are characterized by differential expression levels of NK1.1 and CD44 antigens in C57BL/6 mouse strain. Next generation sequencing of total transcriptomes using total RNA isolated from FACS sorted ex vivo thymic DN1eP (Lin-/CD44+/CD25-/CD24low/CD5+/CD27+/Ly108-/CXCR3+) fraction, and mature thymic alphaGalCer-loaded CD1d dimer+TCRbeta+ NKT cell developmental stage-1 (CD44-/NK1.1-), stage-2 (CD44+/NK1.1-), and stage-3 (CD44+/NK1.1+) cells.

Peripheral tissue instruction is the primary determinant of CD8+ T cell pathogenicity: transcription profiling by array of donor CD8+ effector T cells isolated from the secondary lymphoid organs, blood and GVHD-target organs at D+7 post-transplant (FTY720)

Project description:This study reports the evolution of the donor CD8 effector T cell transcriptomes at multiple sites and time points within the same host following allo-SCT. Donor derived CD8+ T cells were flow sorted from multiple organs in mice developing GVHD in two clinically relevant murine models of H-2b MHC-matched minor antigen-mismatched BMT: (1) B6>129 model – transfer of C57BL/6 polyclonal CD4+ and CD8+ T cells into 129/Sv BMT recipients; (2) F>M – transfer of monoclonal HY-specific TCR-transgenic MataHari CD8+ T cells into C57BL/6 male BMT recipients. To test the effect of early lymph node egress on CD8 effector T cell transcription profile, BMT recipients were treatment with FTY720 (1.0mg/kg/day, from D+3 to D+7).

Altered costimulatory signaling and hypoxia support chromatin landscapes that limit the functional potential of exhausted T cells in cancer [CUT&RUN]

Project description:Increases in terminally exhausted T cells in the tumor are associated with poor responses to immunotherapy, yet the mechanisms that promote progression to terminal exhaustion remain undefined. We profiled the chromatin landscape of subsets of tumor-infiltrating CD8+ T cells using CUT&RUN. CD8 T cells were sorted from the murine B16 melanoma tumor using PD1 and Tim3 expression to define four subsets: PD1lo, PD1mid, PD1hi, and PD1hiTim3+. Additional control samples include paired CD44+ cells from the tumor-draining lymph node of tumor bearing mice, and OT-I effector CD8 T cells isolated from Vaccinia-ova infection. We performed CUT&RUN for H3K4me3, H3K27me3, H3K27ac, and H3K9ac, as well as the transcription factors Tox and Batf.

Transcriptome of activated human and mouse MAIT cells

Project description:We sought to describe in detail the consequences of MAIT cell activation using a transcriptomic approach to define the basic transcriptome of a MAIT cell in both humans and mice and to determine how this is modulated by activation. Fresh human peripheral blood cells were obtained from three donors. These were cultured for 6 hours with (‘stimulated’) or without (‘unstimulated’) 10 nM 5-OP-RU, magnetically enriched on MR1-tetramer+ cells, and flow-sorted for RNA sequencing of live CD3+TCR Valpha7.2+ MR1-5-OP-RU tetramer+ MAIT cells, and of unstimulated naïve live CD8+CD45RA+ T cells as a comparator cell type. For the murine samples we included within the same sequencing experiment live pulmonary CD3+45.2+19-MR1-5-OP-RU tetramer+ MAIT cells which were magnetically enriched and flow-sorted from the lungs of mice 7 days after infection with 1x104 CFU L. longbeachae (‘acute’), or at least 12 weeks post infection (‘resolution’) or 7 days after a second intranasal infection with 2x104 CFU L. longbeachae in mice that had recovered from infection 12 weeks previously (‘reinfection’). Live CD3+CD45.2+CD19-CD8+CD44-CD62L+ naïve T cells from uninfected mice were used as a comparator cell type.
