Question

T helper cells play a role in stimulating [____] formation in B cells. First, the antigen is taken into a(n) [____] and an antigen fragment is displayed on a(n) [____]. The interaction of this molecule with the T-cell receptor [____] the T helper cell. Then, the T helper cell interacts with a B cell, whose antigen receptor is bound to the surface, and the production of [____] released by the T cell activates the B cell and causes proliferation of the B cell. The progeny of the activated B cell differentiate into [____] that can synthesize antibodies that can bind the antigen

(3) antibody; antigen presenting cell; MHC class II molecule; activates; cytokines; plasma cells

(4) activating; antigen presenting cell; TLR 4 molecule; activates; antibodies; plasma cells

(5) cytokine; neutrophil; MHC class II molecule; stimulates; cytokines; natural killer cells

Explanation / Answer

T helper cells play a role in stimulating [____] formation in B cells. First, the antigen is taken into a(n) [____] and an antigen fragment is displayed on a(n) [____]. The interaction of this molecule with the T-cell receptor [____] the T helper cell. Then, the T helper cell interacts with a B cell, whose antigen receptor is bound to the surface, and the production of [____] released by the T cell activates the B cell and causes proliferation of the B cell. The progeny of the activated B cell differentiate into [____] that can synthesize antibodies that can bind the antigen.

The correct answer is option 3.

3) antibody; antigen presenting cell; MHC class II molecule; activates; cytokines; plasma cells
