CD8 (cluster of differentiation 8) is a transmembrane glycoprotein that serves as a co-receptor for the T-cell receptor (TCR). Along with the TCR, the CD8 co-receptor plays a role in T cell …

Expressed on the surface of CD8+ T cells, the CD8 co-receptor is a key component of the T cells that contributes to antigen recognition, immune cell maturation, and immune cell signaling.

CD8+ (cytotoxic) T cells, like CD4+ Helper T cells, are generated in the thymus and express the T-cell receptor. However, rather than the CD4 molecule, cytotoxic T cells express a dimeric co …

CD8 is a transmembrane glycoprotein that functions as a co-receptor for TCR engagement with MHC-I ligands. The CD8 co-receptor can be expressed as a heterodimer of CD8α and CD8β …

Nov 1, 2023 · CD8 T cells play crucial roles in immune surveillance and defense against infections and cancer. After encountering antigenic stimulation, naïve CD8 T cells differentiate and …

Jul 29, 2025 · Among its many components, CD8+ T cells stand out as specialized white blood cells. These cells are a type of lymphocyte and play a significant part in overall immunity. They …

Learn about cytotoxic T cells, also referred to as CD8+ T cells, including cell activation, differentiation, and function in adaptive immune response.

Within the immune system, CD8 T cells are a type of white blood cell responsible for finding and eliminating threats like virally infected cells and cancer cells.

Dec 29, 2025 · They include cytotoxic T cells, which are important for killing cancerous or virally infected cells, and CD8-positive suppressor T cells, which restrain certain types of immune …
