In brief: The innate and adaptive immune systems
2023年8月14日 · The immune system fights germs on the skin, in the tissues of the body, and in bodily fluids such as blood. It is made up of the innate (general) immune system and the adaptive (specialized) immune system. These two systems work …
Innate immune system - Wikipedia
The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants, fungi, prokaryotes, and invertebrates (see Beyond vertebrates). [2 ...

Innate Immunity - Molecular Biology of the Cell - NCBI Bookshelf
The innate immune system relies on the recognition of particular types of molecules that are common to many pathogens but are absent in the host. These pathogen-associated molecules (called pathogen-associated immunostimulants ) stimulate two types of innate immune responses— inflammatory responses (discussed below) and phagocytosis by cells ...
