Blizzard [7]

Answer:

is a way for a cell to give information about its activities.

Explanation:

Antigen-presenting cells (APC) such as dendritic cells, macrophages, and B cells are present where antigens are most likely to penetrate the body. Ingestion of antigens by these cells is followed by digestion of antigen into peptide fragments and their association with MHC molecules.

The antigen-MHC complex is then inserted into the plasma membrane of APCs. The antigens present on the surface of APCs are recognized by the T cells to trigger the adaptive immune response. Antigen processing and antigen presentation by antigen-presenting cells are required to inform the T cells of the immune system about the presence of antigen in the body and immune responses of APCs.
