A long-lived lymphocyte capable of responding to a particular antigen on its reintroduction, long after the exposure that prompted its production.
〔生理〕记忆细胞
Example sentencesExamples
Immune memory cells survive in the host for extended time, retaining their capacity to recognize specific antigens and kill the cells bearing these antigens.
If this is so, then animals living in a pathogen-free environment presumably have fewer memory cells and more naive cells than do animals exposed to bacteria, viruses, and parasites throughout their lives.
Both types of rejection leave memory cells that remain in circulation to mobilize the immune system if the same foreign antigen is reintroduced.
These established memory cells will then be capable of rapidly proliferating upon initial virus infection.
Once the antigenic stimulation is removed, lymphocytes become quiescent and only some remain viable as memory cells.
