Question

In order to be detected by a T cell, the class II major histocompatibility (MHC) molecule of infected cells must go through the process of ________ before presenting the antigen.

A) perforin incorporation
B) antibody binding
C) phagocytosis
D) MHC molecule presentation
E) complement activation

Answer 1

The class II MHC molecule of infected cells must go through the process of antigen processing and presentation before presenting the antigen to be detected by a T cell.

Step-by-step explanation:

The process that the class II major histocompatibility (MHC) molecule of infected cells must go through before presenting the antigen to be detected by a T cell is antigen processing and presentation. Antigens are internalized by antigen-presenting cells (APCs) through phagocytosis, digested, and then brought to the surface of the cell associated with MHC II molecules. This complex of antigen and MHC II is recognized by T cells, leading to T cell activation.
