Question

During the humoral (antibody) response, a macrophage presents foreign epitopes on its ______ molecules, which are detected by _________ and ________ molecules on the T-helper cell surface.

Answer 1

During humoral immunity, antigen presenting cells like macrophages, dendritic cells etc. present an antigen bound to a MHC class 2 molecules to a naive helper T cell. T cell communicate with MHC class 2 molecules by its CD4 receptor molecules and T cell receptor ( TCR).

So, correct answers would be,

During humoral (antibody) response, a macrophage presents foreign epitopes on its MHC Class 2 molecules, which are detected by T cell receptor and CD4 receptor molecules on the T helper cell surface.

Please give a thumbs up if the answer helped you. Thank you :)
