Detailed explanation-1: -The acquired immune response is triggered by recognizing foreign antigen in the cellular context of an activated dendritic cell. With the exception of non-nucleated cells (including erythrocytes), all cells are capable of presenting antigen through the function of major histocompatibility complex (MHC) molecules.
Detailed explanation-2: -Priming is the first contact that antigen-specific T helper cell precursors have with an antigen. It is essential to the T helper cells’ subsequent interaction with B cells to produce antibodies.
Detailed explanation-3: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child’s body.
Detailed explanation-4: -Acquired immunity is pathogen-specific. This means that if a person has developed immunity against the Rubella (German measles) virus, it does not automatically mean that the person is also protected against the polio virus. And the immune system remembers each and every immunological encounter in our body.
