A host cell infected by a virus will activate the adaptive immune response through white blood cells that are called as lymphocytes.
There are two types of responses through cells: antibody responses and cell mediated immune responses. These responses are occur by different types of classes of white blood cells those are called as B cells and T cells.
These T lymphocytes use chemical messenger to activate other immune system cells so that the adaptive immune system can activate. It detect the infected cells and destroy the cell.
Antibody is a blood protein that is produced in body in response to the specific antigen.
