Question

Cells of immune system that cause pore formation in the antigen are

• A. Helper T-cells
• B. Killer T-cells
• C. Suppressor T-cells
• D. B-cells

Answer 1

Answer: (B)

Killer T-cells

A cytotoxic T-cell, also known as Killer T-cells is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected (particularly with viruses), or cells that are damaged in other ways. When killer T-cells are exposed to antigens, they release the cytotoxins perforin, granzymes, and granulysin. Perforins and granzymes causes pore formation in the antigen which causes the intracellular content of antigen to leak out resulting in cell death.

So, the correct answer is 'Killer T-cells'.
