of pathogen-specific effector cells, include _______

a) CD4+ T cells and CD8+ T cells
b) only CD4+ T cells
c) naïve CD4+ T cells and naïve CD8+ T cells
d) only CD8+ T cells
e) CD4 + T cells and naive T cells

Verified Answer :

Answer: a)  CD4+ T cells and CD8+ T cells

Explanation: Memory T cells are a type of immune cells that contain information regarding the previous infections so, they quickly respond and they fight against to the previous pathogen. Memory T cells include these both subtypes, allowing the immune system to remember and affectively respond to previously encountered antigens.

CD4+ T cells ==> These are also called as Helper T cells. These cells are helping to other immune cells by releasing cytokines that enhance the immune response. They play vital role in orchestrating the immune response, including helping B cells to produce antibodies and activating other T cells.

CD8+ Cells ==> These are also called as Cytoxic T cells. These cells directly attacks on cancerous cells. These cells plays vital role for controlling viral infections and targeting cells that have been infected by pathogens.
