What is the Correct Outcome of CD8⁺ Cell Activation

Question

What is the correct outcome of CD8⁺ cell activation?
A)production of Interleukin-2,stimulation of B-cells for antibody production
B)response to MHC I-peptide complexes,differentiation into TH and memory cells
C)The cytotoxic killing of infected cells,production of memory cells
D)response to MHC I-peptide complexes,production of Interleukin-2
E)production of Interleukin-1,stimulation of B-cells for antibody production

Accepted Answer

The correct outcome of CD8⁺ cell activation is the cytotoxic killing of infected cells and the production of memory cells. CD8⁺ cells are cytotoxic T cells that recognize and respond to MHC I-peptide complexes on infected cells, leading to their elimination through various mechanisms including release of granzyme and perforin. Additionally, activated CD8⁺ cells differentiate into memory cells which can provide long-lasting immunity against subsequent infections by the same pathogen. None of the other options describe the correct outcome of CD8⁺ cell activation.
