These cells are involved in both the induction and the restraint of most immunological functions. A key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T cell.

The expression of CD4 and CD8αβ co-receptors on mature T cells is generally considered to be mutually exclusive and reflects subset-related, specific functions (helper vs. cytolytic) and differences in major histocompatibility complex-restriction for antigen recognition. However, double positive (DP...

(MHC class II transactivator) ( Accolla R.S. et al. 1986) can be rejected effectively, generating tumor specific T helper cell (TH) triggering, immunological memory and protection even against parental tumor (Meazza R. et al. 2003 ; Frangione V. et al. 2010; Mortara L. et al. 2006) ...
However, the role of serine/threonine phosphorylation in the function of SHP-1 remains unclear23. In this study, we established mice lacking all PKD isoforms in T cells. The generation of CD4 SP thymocytes is impaired in these T cell-specific PKD-deficient mice. Using a phosphoproteomic ...
DP T cells, during their thymic development, undergo selection to become either CD4+helper T cells or CD8+cytotoxic T cells based on the strength and specificity of their interactions with MHC class I or MHC class II molecules. Unlike DP thymocytes, which are well-known as a stage in T ce...
A progressive loss of circulating anti-human epidermal growth factor receptor-2/neu (HER2) CD4+ T-helper type 1 (Th1) immune responses is observed in HER2pos-invasive breast cancer (IBC) patients relative to healthy controls. Pathologic complete response (pCR) following neoadjuvant trastuzumab and...

Therefore, we investigated the presence and functional reactivity of autoreactive T-cell responses against autologous AML blasts....
