The adaptive immune system, also known as the acquired immune system, or specific immune system is a subsystem of the immune system that is composed of specialized, systemic cells and processes that eliminate pathogens or prevent their growth. The acquired immune system is one of the two main immunity strategies found in vertebrates (the other ...

The adaptive immune system evolved in early vertebrates and allows for a stronger immune response as well as immunological memory, where each pathogen is "remembered" by a signature antigen. The adaptive immune response is antigen-specific and requires the recognition of specific "non-self" antigens during a process called antigen presentation .
The adaptive immune system is made of specialized cells and processes which kill pathogens or prevent their attack. The adaptive immune system is switched on by the evolutionarily older innate immune system. [1] This older system is non-specific, whereas the adaptive system is tailored to specific targets. Whereas the innate immune system is ...
The adaptive immune system, also called acquired immunity, uses specific antigens to strategically mount an immune response. Unlike the innate immune system, which attacks only based on the identification of general threats, the adaptive immunity is activated by exposure to pathogens, and uses an immunological memory to learn about the threat ...

The adaptive immune response is the body's second line of defense. The cells of the adaptive immune system are extremely specific because during early developmental stages the B and T cells develop antigen receptors that are specific to only certain antigens. This is extremely important for B and T cell activation.
Aug 14, 2023 · The adaptive immune system: Fighting the germs directly. If the innate (general) immune system fails to destroy the germs, the adaptive (specialized) immune system takes over. The adaptive immune system specifically targets the type of germ that is causing the infection. But to do that, it first needs to recognize the germ as such.

Aug 5, 2022 · 1. As innate immunity advances to adaptive immunity, “our worst enemy,” immunity moves from “friend to foe.”. 2. As adaptive immunity advances, it begins to disrupt the homeostasis (maintenance of a stable condition) of your body and your overall immune system. This disruption is referred to as “dysregulation” of the immune system.
