Study Notes
Phagocytosis Process Overview
- Phagocytosis is a crucial immune response that involves five key steps: chemotaxis, adherence, ingestion, digestion, and elimination.
Chemotaxis
- Defined as the movement of cells in response to chemical signals.
- Pseudopodia extend towards microorganisms at the infection site, guiding immune cells to pathogens.
Adherence
- This step involves the physical attachment of phagocytes to microbes.
- Strong adherence is essential for the subsequent engulfment of pathogens.
Ingestion
- Involves engulfing the pathogen using extensions called pseudopodia.
- The engulfed pathogen is encapsulated within a vesicle, known as a phagosome, which contains lysozymes for digestion.
Digestion
- The phagosome undergoes maturation, where it merges with a lysosome to form a phagolysosome.
- Within the phagolysosome, digestive enzymes are released, leading to the destruction of most microbes.
Elimination
- Remaining fragments of the digested microbes are expelled from the phagocyte through exocytosis.
- Some microbial components may be retained to inform and prepare the immune system for future attacks by the same pathogen.
