Verified step by step guidance1
Understand the role of lymphocytes in the immune system. Lymphocytes are a type of white blood cell that play a critical role in adaptive immunity, including recognizing and responding to specific antigens.
Learn about the major classes of lymphocytes: B cells, T cells, and natural killer (NK) cells. B cells are responsible for antibody production, NK cells are involved in innate immunity, and T cells are central to adaptive immunity.
Differentiate between the two main subsets of T cells: CD4+ T cells and CD8+ T cells. CD4+ T cells are helper T cells that assist other immune cells, while CD8+ T cells are cytotoxic T cells that directly kill infected or cancerous cells.
Focus on the differentiation process of CD8+ T cells. These cells are activated by antigen-presenting cells and differentiate into cytotoxic T cells, which target and destroy infected or abnormal cells.
Conclude that the major class of lymphocytes that differentiates into cytotoxic T cells is CD8+ T cells, based on their specific function and role in adaptive immunity.
