CD4+ t cells are activated by interaction between CD4+ and MHC II.

What is MHC molecule?</h3>
- Antigens are foreign proteins that enter the host body through an infection. Antigens are generally high molecular weight proteins or polysaccharides. Viruses and bacteria contain antigen on their surface or inside the body.
- Epitope is the molecular region on the surface of the antigen which interact with the antibody binding site on the antigen. Epitopes are capable of stimulating an immune response so, these are also known as antigenic determinants. Binding between the receptor and epitopes occurs when they both fit together like a puzzle, that event is necessary to activate B-cell production of antibodies.
- A sizable region of vertebrate DNA called the major histocompatibility complex houses a group of closely related polymorphic genes that code for the cell surface proteins needed by the adaptive immune system. These MHC molecules are cell surface proteins.
- A controlled, efficient immune response to pathogens depends on CD4+T cells. After interacting with the antigen-MHC complex, naive CD4+T cells become activated and undergo specialized subtype differentiation that is largely influenced by the cytokine milieu of the microenvironment.
- Hence the correct answer is interaction between CD4+ and MHC II.
