Vedclass · Answer

(C) Perforin is a cytolytic protein found in the granules of Cytotoxic $T$-lymphocytes and Natural Killer $(NK)$ cells. Upon activation,these cells release perforin,which inserts itself into the target cell membrane to form pores. These pores allow water and ions to enter the target cell,leading to osmotic lysis and the destruction of the microbe-infected cell.

Perforin is secreted by which of the following cells to prevent the effect of microbes?
