Lecture Note

The discipline of immunology emerged from the observation that individuals who recovered from certain infectious diseases were thereafter protected from the disease. The immune system evolved to protect multicellular organisms from pathogens. The immune system is highly adaptable and defends the body against diverse invaders. The diversity of potential pathogens requires a range of recognition and destruction mechanisms to match the multitude of invaders. Immunity is a state of protection from infectious disease. The body is protected from infectious agents and other harmful substances by a variety of cells and molecules that make up the immune system. Immunity is the ability of the human body to tolerate the presence of materials indigenous to the body (self) and to eliminate foreign (non-self) materials. Foreign substances such as viruses, bacteria, toxins and parasites are surrounded by antigens that when introduced into the body are capable of inducing a response by the immune system.
