CD8 - Wikipedia
网页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 signaling and aiding with cytotoxic T cell-antigen interactions.
What to Know About the CD4:CD8 Ratio Test - WebMD
网页2022年5月4日 · The total CD4 number, their proportion (CD4 percentage), and their ratio to CD8 cells (CD4:CD8 ratio) are tests used to guide HIV treatment. A CD4:CD8 ratio of more than 1.0 is considered...
CD4/CD8 Ratio: What to Know - Verywell Health
网页2024年3月21日 · The CD4/CD8 ratio is a blood test used to monitor the immune systems of people with HIV and other disorders. CD4 and CD8 cells react correspondingly to each other and their ratio (whether low or high) can indicate certain illnesses like HIV, multiple sclerosis, or blood cancer.

CD8 + T cell metabolism in infection and cancer - PubMed
网页Cytotoxic CD8 + T cells play a key role in the elimination of intracellular infections and malignant cells and can provide long-term protective immunity. In the response to infection, CD8<sup>+</sup> T cell metabolism is coupled to transcriptional, translational and epigenetic changes that …
Cells T CD8+ | British Society for Immunology
网页CD8+ T cells (often called cytotoxic T lymphocytes, or CTLs) are very important for immune defence against intracellular pathogens, including viruses and bacteria, and for tumour surveillance. When a CD8+ T cell recognises its antigen and becomes activated, it has three major mechanisms to kill infected or malignant cells.
