Effector differentiation and therapeutic reinvigoration of CD8+ T cells in chronic infection depend on KLF2-directed lymph node homing

ABSTRACT: In this study, we examine the heterogeneity and molecular regulation of CD8 T cells in chronic infection across lymph nodes and spleen. We find that lymph nodes, not the spleen, support the stemness and polyfunctionality of CD8 T cells and their response to PD-1 blocking therapy. We discover that the transcription factor KLF2 is specifically expressed in and required for stem-like precursor and effector-like T cells. Finally, we show that migratory dendritic cell in the lymph nodes support the differentiation and function of CD8 T cells.

Lymphoid tissue specific homing of bone marrow-derived dendritic cells

Project description:Because of their potent immunoregulatory capacity, dendritic cells (DCs) have been exploited as therapeutic tools to boost immune responses against tumors or pathogens, or dampen autoimmune or allergic responses. Murine bone marrow-derived DCs (BM-DCs) are the closest known equivalent of the blood monocyte-derived DCs that have been used for human therapy. Current imaging methods have proven unable to properly address the migration of injected DCs to small and deep tissues in mice and humans. This study presents the first extensive analysis of BM-DC homing to lymph nodes (and other selected tissues) after intravenous and intraperitoneal inoculation. Following intravenous delivery, DCs accumulated in the spleen, and preferentially in the pancreatic and lung-draining lymph nodes. In contrast, DCs injected intraperitoneally were found predominantly in peritoneal lymph nodes (pancreatic in particular), and in omentum-associated lymphoid tissue. This uneven distribution of BM-DCs, independent of the mouse strain and also observed within pancreatic lymph nodes, resulted in the uneven induction of an immune response in different lymphoid tissues. These data have important implications for the design of systemic cellular therapy with DCs, and in particular underlie a previously unsuspected potential for specific treatment of diseases such as autoimmune diabetes and pancreatic cancer.

Optimized CD8 effector TL

Project description:Transcriptome analyses of naive, effector and memory CD8 TCRP1A lymphocytes expressing or not an active form of the transcription factor Stat5. TCRP1A CD8 T lymphocytes were activated by their cognate Ag for 72h to induce their differentiation in effector T cells (TCRP1A eTL 72h: 4 replicates S1, S2, S3, S4). In some samples, an active form of Stat5 was introduced (TCRP1A Stat5ca eTL 72h: 2 replicates S9, S10). These 72h activated T cells were either purified and analyzed directly (samples mentioned above) or injected in congeneic hosts and recovered more than 20 days later from the host spleen and lymph nodes: TCRP1A eTL >d20: 2 replicates– S30, S32; TCRP1A Stat5ca eTL >d20: 4 replicates S11, S12, S13, S14). Naive TCRP1A CD8 T lymphocytes (TCRP1A-naive: 4 replicates S33, S34, S35, S36) are included as controls. TCRP1A CD8 T lymphocytes were activated by anti-CD3/CD28. After 24h, an active form of Stat5 was introduced in activated cells. Culture was continued for another 48h to induce their differentiation in effector T cells. These 72h activated T cells were either directly injected in congeneic hosts and recovered more than 14 days later from the host spleen and lymph nodes: T-BetKO Stat5ca >d14: 3 replicates S39, S40, S41.

Gene expression analysis of Wnt+ and Wnt- effector CD8 T cells

Project description:Wnt signal transduction during an immune response is involved in the establishment of functional CD8 T cell memory P14 ConductinLacZ CD8 T cells (CD45.2) were transferred in CD45.1+.2+ recipient mice. The day after, recipients were infected with 200pfu LCMV WE. At day 8 after infection, cells from spleen and lymph nodes were harvested, magnetically enriched for CD8 T cells, loaded with the beta-galactosidase substrate (FDG) and sorted as 7AAD-negative CD45.- negative, beta-galactosidase positive versus negative cells. P14 CD8 T cells were sorted at day 8 after LCMV infection according to LacZ activity for RNA extraction and hybridization on Affymetrix microarrays.
