Study Notes
Innate Immunity: The First Line of Defense Against Infections
- Innate immunity is the first line of defense against infections in multicellular organisms.
- Innate immunity is also known as natural immunity or native immunity.
- The cells and molecules responsible for innate immunity make up the innate immune system.
- Innate immunity blocks microbial invasion through epithelial barriers, destroys many microbes that do enter the body, and is capable of controlling and even eradicating infections.
- The innate immune response is able to combat microbes immediately upon infection while the adaptive immune response needs to be stimulated by antigen and is delayed.
- Innate immunity provides essential protection against infections during this delay.
- Innate immunity is a key participant in the clearance of dead tissues and the initiation of repair after tissue damage.
- The innate immune system performs its defensive functions with a small set of reactions, which are more limited than the varied and specialized responses of adaptive immunity.
- The specificity of innate immunity is different from the specificity of lymphocytes, the antigen-recognizing cells of adaptive immunity.
- The two principal types of reactions of the innate immune system are inflammation and antiviral defense.
- Innate immune receptors recognize pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs).
- The innate immune system does not react against healthy cells due to several features, including the specificity of receptors and the presence of regulatory molecules.
