Phenotypes of Th lineages generated by the commonly used activation with anti-CD3/CD28 antibodies differ from those generated by the physiological activation with the specific antigen

Project description:T-helper (Th) lineages have been generated in vitro by activating CD4 cells with anti-CD3/CD28 antibodies during polarization. Physiologically, however, the generation of Th lineages is by activation with the specific antigen presented by antigen-presenting cells (APC). Here, we used TCR-transgenic mice to compare the phenotypes of Th1, Th9 and Th17 lineages when generated by either one of the two activation modes. Lineage Th cells specific against hen egg lysozyme (HEL), were adoptively transferred into recipient mice transgenically expressing HEL in their lens. Remarkable differences were found between lineages of Th1, Th9, or Th17, generated by either one of the two modes in their capacities to migrate to and proliferate in the recipient spleen and, importantly, to induce inflammation in the recipient mouse eyes. Substantial differences were also observed between the lineage pairs in their transcript expression profiles of certain chemokines and chemokine receptors. Surprisingly, however, close similarities were observed between the transcript expression profiles of lineages of the three phenotypes, activated by the same mode. Furthermore, Th cell lineages generated by the two activation modes differed considerably in their pattern of gene expression, as monitored by microarray analysis, but exhibited commonality with lineages of other phenotypes generated by the same activation mode. This study thus shows that (i) Th lineages generated by activation with anti-CD3/CD28 antibodies differ from lineages generated by antigen/APC and (ii) the mode of activation determines to a large extent the expression profile of major transcripts NaM-CM-/ve CD4+ T cells purified from spleen and lymph node cells of 3A9 mice were activated and polarized toward Th1, Th9, and Th17 lineages, under either plate bound anti-CD3/anti-CD28 (PBAB) or APC presented HEL protein (HA).

Pathogenic TH17 cells utilize BHLHE40 to instruct myeloid cells during autoimmune neuroinflammation

Project description:TH17 cells are implicated in the pathogenesis of multiple sclerosis and experimental autoimmune encephalomyelitis (EAE). We previously reported that the transcription factor BHLHE40 marks cytokine-producing pathogenic TH cells during EAE, and that its expression in T cells is required for clinical disease. Here, using dual reporter mice, we show BHLHE40 expression within TH1/17 and ex-TH17 cells following EAE induction. Il17a-Cre-mediated deletion of BHLHE40 in TH cells led to less severe EAE with reduced TH cell cytokine production. Characterization of the leukocytes in the central nervous system during EAE by scRNA-sequencing identified differences in the infiltrating myeloid cells when BHLHE40 was present or absent in TH17 cells. Our studies highlight the importance of BHLHE40 in promoting TH17 cell encephalitogenicity and instructing myeloid cell responses during active EAE.

Transcriptional profilling of pathogen-specific T helper cells

Project description:Introduction: We reported a in vitro pathogen-specific priming system to using pathogen lysate stimulated splenic CD11c+ DCs to differentiate pathogen-specific murine T helper cells. This method allowed us to compare side-by-side transcriptional profiles of bulk T helper cells that are specific to distinct pathogens and to study their composition and functionality. Method: We stimulated mouse splenic CD11c+ DCs with 10ug/ml Lm or Cr lysate for 5hours. The DCs were subsequently washed and co-cultured at 1:5 ratio to purified, CFSE-labeled CD62L+CD44- mouse naïve CD4 T cells. At day-7, CD90+CFSE- (Pathogen-specific Th cells) or CD90+CFSE+ (naive T cells) were sorted from the same culture and were subjected to RNA isolation, library prep and subsequent sequencing. Conclusion: We found that Lm- and Cr-specific Th cells have distinct transcriptomes and contained distinct Th subtypes. Lm-specific Th cells contained higher expressions of Th1-associated cytokines, while Cr-specific Th cells contained higher levels of Th17 associate cytokines and transcription factors. In addition, we have identified heterogeneity within the pathogen-specific Th cells, as they express various cytokines from multiple Th lineages. Lastly, we found a vast variety of genes differentially expressed between Lm- and Cr-specific Th cells, indicating that different pathogen-stimulated DCs denote distinct function and developmental cues to T cells during differentiation.

Transcription profiling of human monocytes cultured in the presence of M-CSF for 7 days and polarized to M1 or M2 cells to characterize human monocyte-to-macrophage differentiation and polarization

Project description:Monocytes mature to macrophages in the presence of the lineage determining cytokine M-CSF. They can be further polarized into M1 or M2 macrophages with distinct functional properties. We used microarrays to detail the global programme of gene expression underlying macrophage maturation and polarization and identified distinct classes of up-regulated genes during this process. Experiment Overall Design: Freshly isolated monocytes were cultured in the presence of M-CSF for 7 days, and then polarized to M1 or M2 cells. The study includes Monocytes at day 0, macrophages at day 3 and 7, M1 and m2 polarized macrophages.

GM-CSF-producing T helper cells: a distinct subset of T helper cells that acquire Th1 phenotype during the CNS inflammation.

Project description:Using scRNA-seq and CyTOF, we identified eight populations of antigen-experienced CD45RA-CD4+ T cells in blood of healthy donors, including a population of GM-CSF-producing Th cells (ThGM) that lacked expression of signature transcription factors and cytokines of established Th lineages. In addition to GM-CSF, human and mouse ThGM cells also expressed IL-2, TNF, IL-3 and CCL20. ThGM cells maintained their phenotype through several cycles of activation, but upregulated expression of T-bet and IFN-g upon exposure to IL-12 in vitro, and in the CNS of mice with autoimmune neuroinflammation. ThGM cells were encephalitogenic; T-bet was not required for their development, but it was required for their encephalitogenicity. These findings demonstrate that ThGM cells constitute a distinct population of Th cells with lineage characteristics.
