Activation-induced cytidine deaminase (AID) is an enzyme involved in somatic hypermutation and class-switch recombination during antibody production.
Think of AID as a molecular editor that works on the blueprint of antibodies. It goes through the genetic code and makes specific changes, like adding new colors or rearranging patterns, to create unique and effective weapons against pathogens.
Somatic Hypermutation: A process where B-cells randomly mutate their antibody genes to generate a diverse repertoire of antibodies.
Class-Switch Recombination: A process where B-cells change the class (IgM, IgG, etc.) of antibodies they produce while maintaining specificity.
Antibodies: Proteins produced by B-cells that recognize and neutralize foreign substances in the body.
