The immune system is a biological defense mechanism that helps all tissues to be resistant to infection. The immune system is classified into three major subsets: B and T cells; R Cells; and M cells. B and T cells are further subclassified into Th cells and White Blood Cells. White Blood Cells carries out a specific function in the human body: they can either attack or defend the body against diseases. In the case of the immunity system, the goal is to suppress or eliminate alien organisms that invade the body. While the major function of the immune system is to protect the body from pathogenic organisms, its ability to recognize pathogenic agents and to mount an effective defense depends largely on the type of cells it has recruited to act as its defense mechanism.
The innate immune system works by identifying allergens by the body’s innate immune response and then mounts an action against it. These antigens have been identified through studies in animals like rabbits and guinea pigs. These tests have proven that humans can make antibodies against many common allergens. Common substances which are found to be allergens include dust, pollen, mold spores, cat and dog dander. These antigens also have cell-signature which can be identified through laboratory methods.
