What is another name for helper T-lymphocytes?

• A. Cytotoxic T-lymphocytes
• B. CD8+ cells
• C. CD4+ cells
• D. Memory T-lymphocytes

Answer: (C)

Helper T-lymphocytes are primarily known as CD4+ cells because they express the CD4 glycoprotein on their surface. This marker is crucial for their function, as it helps distinguish them from other types of T cells, such as cytotoxic T-lymphocytes, which express CD8. Helper T cells play a vital role in the immune response by assisting other immune cells, such as B cells in antibody production and cytotoxic T cells in recognizing and destroying infected cells. Their designation as CD4+ cells is fundamental in immunology, particularly when discussing T cell subsets and their respective roles in the adaptive immune system.
