Question

Which of the following statement is incorrect in regards to CD4 activation and differentiation into TH1 and TH2 cells?

a. TH2 cells produce IL-5 which recruits eosinophils.
b. TH1 cells produce IL-3 and IL-9 which recruits mast cells.
c. TH2 cells produce IL-13 which increases production of epithelial cells.
d. TH1 cells secrete Interferon g and activates macrophages.

Answer 1

The correct statement is option b. TH1 cells do not produce IL-3 and IL-9 which recruit mast cells.

Step-by-step explanation:

The correct statement in regards to CD4 activation and differentiation into TH1 and TH2 cells is option b. TH1 cells produce IL-3 and IL-9 which do not recruit mast cells. TH2 cells, on the other hand, produce IL-5 which recruits eosinophils, IL-13 which increases production of epithelial cells, and TH1 cells secrete Interferon g which activates macrophages.
