The innate immune system is the body's first line of defense against pathogens. Its protective capabilities are provided by several key factors.
Based on the reference provided, the factors of the innate immune system include:
- Physical and Anatomical Barriers: These prevent pathogens from entering the body. Skin and mucosa provide an effective immune barrier between the internal and external environment.
- Effector Cells: Various cells that recognize and eliminate pathogens.
- Antimicrobial Peptides: Molecules that can directly kill microbes.
- Soluble Mediators: Proteins and other molecules released to regulate the immune response and fight infection.
- Cell Receptors: Molecules on the surface of innate immune cells that recognize pathogen-associated molecules.
These components work together rapidly to detect and respond to threats, forming a crucial defense mechanism without prior exposure to a pathogen.
