What does CMI mean in PHYSIOLOGY

Immune cells are special cells in the body that can recognize and kill pathogens, such as bacteria and viruses, as well as other foreign substances in the body that might cause disease or infection. These immune cells work together with other parts of the immune system to create an effective response to threats or infections.

CMI helps the body to fight off infections by activating immune cells which can then recognize and respond to potential threats. The activated immune cells can then work together with other parts of the innate and adaptive immune system to launch an effective response against invading organisms or substances.

When a potential threat is detected by an antigen presenting cell (APC), it will present antigens on its surface to an appropriate T cell receptor (TCR). This will activate a series of reactions which will trigger an appropriate response from the T cell, resulting in antigen destruction or adjustment of other protective mechanisms.

An APC is a specialized type of white blood cell capable of recognizing antigens on pathogens or certain foreign bodies which may have entered the body's tissue. This recognition process initiates a cascade reaction eventually leading to activation of T Cells, which are necessary for effective cellular immunity.

T Cells are part of our adaptive immune system, which is responsible for recognizing harmful substances entering our body when our innate defense systems fail. They interact with antigens presented by antigen presenting cells (APCs) in order to recognize them and initiate an appropriate response according to their type; either killing them directly or stimulating other arms of our immunity against them.
