Abstract

Immunity is the capability to detect, resist, and overcome a challenge that is posed by any foreign substance. This is carried out by a set of organs and tissues that are collectively referred to as the immune system. Its adaptive branch is able to respond to virtually any feature on a pathogen by the generation of highly specific receptors that recognize this so-called antigen—it adapts to the challenge and also ensures highly specific and long-lasting protection1.
