What are the Key Mechanisms of the Innate Immune Response?
Several mechanisms are employed by the innate immune system to combat pathogens:
Phagocytosis: Cells like macrophages and neutrophils engulf and digest pathogens. Inflammation: The release of cytokines and chemokines leads to increased blood flow and the recruitment of immune cells to the site of infection. Complement System: This is a group of proteins that can directly kill pathogens or mark them for destruction by other immune cells. Antimicrobial Peptides: These are small proteins that can directly kill bacteria, fungi, and viruses.
