Study Notes
Neutrophil Extracellular Traps (NETs)
- NETs are a defense mechanism utilized by neutrophils to ensnare and neutralize pathogens.
- Certain pathogens have developed strategies to evade NETs.
Natural Killer (NK) Cells and Cytotoxic T Lymphocytes (CTLs)
- NK cells induce apoptosis in infected cells, similar to CTLs, effectively killing them.
- The mechanism of action involves prompting cells to undergo programmed cell death.
Monokines
- Monokines are a type of cytokine secreted by monocytes or macrophages.
- They play a role in immune responses without the involvement of antibodies.
Serum Amyloid P Component and Alpha-1 Acid Glycoprotein
- Serum amyloid P component and alpha-1 acid glycoprotein are associated with immune responses.
Immunoglobulin M (IgM)
- IgM is a type of antibody that plays a crucial role in the immune system by attaching to antigens.
- Antibodies recognize and bind to proteins or large structures that serve as antigens.
Complement Activation
- The alternative pathway of the complement system can be activated by the interaction between C3b and pathogens.
Phagocytosis
- Macrophages can ingest and eliminate bacteria through a process called phagocytosis, enhancing immune defense.
