Question

Which of the following are NOT matched correctly?

CD8+: directly destroy infected or cancerous cells
T reg cell: reduce the adaptive response once threat passes
T helper l: activate cellular branch (Cytotoxic T cells, macrophages, NK cells)
T helper 2: stimulate B cells to make antibodies
T helper (CD4+): MHC I

Answer 1

T helper (CD4+): MHC I

Step-by-step explanation:

T helper (CD4+) should be matched with MHC Class II while MHC Class I should be matched with T cytotoxic (CD 8+) cells. This is because T helper cells coreceptors recognize antigen presented on MHC II, to become an effector cell, while CD8+ recognize antigen presented by MHC I.
