Core principles characterizing immune function

Abstract:
The immune system is an anticipatory mechanism designed by evolution to protect the individual against noxious agents and harmful cellular debris. In order to recognize substances that it has never encountered, the immune system somatically generates an appropriately sized random (with respect to self and nonself [NS]) recognitive repertoire that is coupled to a biodestructive and ridding output. Consequently, a Self-NS discrimination is required in order to avoid autoimmunity. This essay is an attempt to highlight the core principles upon which this anticipatory mechanism depends in order to function.

01:23Introduction to Lymphatic and Immune System
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are born...
01:21Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
