Classification
Nouns denoting substances.
Examples
- CD8 is a key receptor on cytotoxic T cells, allowing them to recognize antigens presented by MHC class I molecules on infected cells.
- The CD8 molecule plays a crucial role in the recognition and killing of infected cells by cytotoxic T cells during the immune response.
- Studies have shown that the expression of CD8 on the surface of T cells is upregulated in response to viral infections.
- CD8-positive T cells are typically involved in cell-mediated immune responses, where they directly kill infected cells.
- In the immune system, CD8 is often co-expressed with CD3 and other cell surface receptors to facilitate the recognition and elimination of pathogens.
