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.
