Cytotoxic t cells produce cytotoxins which cause apoptosis of infected cells.

a) true
b) false

A) TRUE

Explanation:

The cytotoxins produced by Cytotoxic T cells, are proteins like perforine which binds to the membrane of an infected cell (with a virus or cancerogenous), causing the cell to die or apoptosis. This mechanism is very important for the immune system to attack pathogens, but it also needs to be very well regulated.
