T-cell biology

T-cells are a type of white blood cell crucial for the immune system. They originate from bone marrow and mature in the thymus. T-cells identify and attack infected or cancerous cells using special receptors. There are several types, including helper T-cells, which coordinate the immune response, and cytotoxic T-cells, which directly kill infected or abnormal cells. When T-cells encounter their specific target, they activate and multiply to eliminate the threat. This process is essential for protecting the body against infections and diseases. Their ability to remember past infections also helps the body respond more swiftly in the future.
