WebOverview. T helper type 1 (Th1) cells are a subset of CD4 + effector T cells that is required for host defense against intracellular viral and bacterial pathogens. Th1 cells develop from activated, naïve CD4 + T cells in the presence of IL-27, IL-12, and IFN-gamma. They can be distinguished from other CD3 + CD4 + CD8-T cells based on the cell surface expression of … Web14 Jul 2015 · CD44 is a prominent activation marker which distinguishes memory and effector T cells from their naïve counterparts. It also plays a role in early T cell signaling events as it is bound to the lymphocyte-specific protein kinase and thereby enhances T cell receptor signalling. Here, we investigated whether IFN-γ and IL-17 producing T helper cells …
