Immuunvastustes

Immuunvastustes, also known as immune tolerance, refers to the state in which the immune system does not react to a particular antigen, allowing the body to tolerate that antigen without causing harm. This phenomenon is crucial for maintaining homeostasis and preventing autoimmune diseases. Immune tolerance can be induced naturally or artificially. Naturally, it occurs during fetal development, where the fetus develops tolerance to its own tissues, and during the maturation of the immune system, where self-reactive T cells are eliminated. Artificially, immune tolerance can be induced through various methods, such as the administration of tolerogenic dendritic cells, regulatory T cells, or the use of immunosuppressive drugs.

Immuunvastustes is essential for preventing autoimmune diseases, where the immune system mistakenly attacks the body's own tissues. It is also a key mechanism in organ transplantation, where immune tolerance to the transplanted organ is induced to prevent rejection. Understanding the mechanisms underlying immune tolerance is an active area of research, with the goal of developing new therapies for autoimmune diseases and improving organ transplantation outcomes.
