Cells of Immune System- Types and Examples - Microbe Notes
2022年5月17日 · The lymphocytes are the central cells of the immune system which are responsible for adaptive immunity and immunological features of diversity, specificity, memory, and self/non-self recognition. The other immune cells function to engulf and destroy micro-organisms, present antigens and secrete cytokines.
