Effective adaptive immune responses toward pathogens depend upon the proper differentiation of CD4 T cells into particular effector cell types. TH1 cells are responsible for clearance of intracellular infection and are implicated as the effectors in various autoimmune diseases; TH2 cells control extracellular microbe infection as well as mediate chronic inflammation and allergic responses; and a recently identified third subset, TH17 cells, has been linked to a growing list of autoimmune disorders.TCR and cytokines signaling is critical for downstream gene expression and T cell fate determination. While the signaling network in T cells has largely been described, the impact of non-coding RNAs (ncRNAs) on this network is largely unknown. miRNAs that affect mature T cell functional differentiation.
We revealed that miR-17 and miR-19b are the key players controlling TH1 responses through multiple coordinated biologic processes. These include: promoting proliferation, protecting cells from activation-induced cell death, supporting IFN-γ production, and suppressing inducible regulatory T-cell differentiation. Mechanistically, we identified Pten (phosphatase and tensin homolog) as the functionally important target of miR-19b, whereas the function of miR-17 is mediated by TGFβRII and the novel target CREB1. Our results suggest that miR-19b and miR-17 could be harnessed to enhance the efficacy of T cell-based tumor therapy. (Blood. 2011 Nov 17;118(20):5487-97.)
We also revealed that Methyl CpG binding protein 2 (MeCP2) was indispensable for the differentiation of naïve CD4 (+) T cells into TH1 and TH17 cells. Loss of MeCP2 in CD4 (+) T cells impaired the expression of the miR-124 and consequently relieved miR-124-mediated repression of the translation of suppressor of cytokine signaling 5 (Socs5) mRNA. The resulting accumulation of SOCS5 inhibited the cytokine-dependent activation of signal transducer and activator of transcription 1 (STAT1) and STAT3, which are necessary for the differentiation of TH1 and TH17 cells, respectively. Meanwhile MeCP2 enforces Foxp3 expression to promote nTreg’s resilience to inflammation. (Sci Signal. 2014 Mar 11; 7 (316):ra25.)
Currently, we are studying in three directions:
1. To determine the immunotherapeutic efficacy of micorRNAs-modified CAR-T cells against human tumors.
2. To characterize the roles of microRNAs in the immune suppression of T cells in the tumor environment.
3. To characterize the roles of microRNAS in memory T cells generation.
