Autoimmunity
Autoimmunity evolved in higher vertebrates. It is based on the ability to differentiate non-self cells from self-cells. In autoimmunity, the body attacks self-cells. This results in damage to the body. These diseases in which the body attacks self-cells are called autoimmune diseases.
Myasthenia Gravis and Rheumatoid Arthritis are examples of autoimmune diseases. Both genetic tendency and environmental triggers, such as infections or certain medications, can contribute to the development of autoimmune disorders. Autoimmunity leads to inflammation and tissue damage, impacting the proper functioning of affected organs or systems.
Immunity – Definition, Types and Vaccination
Immunity is a defense mechanism of the body that is provided by the immune system and helps in fighting disease-causing organisms. There are two immunity types: innate and acquired immunity. Immunity-enhancing foods help boost the body’s immune system Vaccination also enhances immunity by exposing the immune system to harmless antigens, preparing it to give a quicker and stronger response upon encountering the disease-causing pathogen.
In this article, we will study immunity and its type, vaccination, and immunization.
