CD8+ T cells

CD8+ T cells, also known as cytotoxic T cells, are a type of immune cell that plays a crucial role in defending the body against infections and cancer. They identify and destroy cells that have been infected by viruses or that are dysfunctional, such as tumor cells. CD8+ T cells recognize infected or abnormal cells by detecting specific proteins on their surfaces. Once they find a target, they release substances that kill the harmful cells, helping to maintain the body's health and protect against disease. Their activity is vital for a strong and effective immune response.
