How are T Cells Involved in Immunological Reactions?
T cells are a type of lymphocyte that play a central role in cell-mediated immunity. There are several subsets of T cells, including:
- Cytotoxic T Cells: These cells kill infected or cancerous cells. - Helper T Cells: These cells assist other immune cells by releasing cytokines. - Regulatory T Cells: These cells help maintain immune tolerance and prevent autoimmune reactions.
In histological studies, the presence and activity of T cells can be assessed using various markers and staining techniques.
