Study Notes
Neutrophils
- Primary immune cells responsible for phagocytosis and destruction of pathogens.
- Play a significant role in extracellular killing through the release of enzymes and reactive oxygen species.
Immunity Types
- Nonspecific immunity, also known as innate immunity, is effective from birth and provides broad defense against pathogens.
- Adaptive immunity develops specifically after exposure to pathogens or foreign substances.
Dendritic Cells
- Act as antigen-presenting cells that process and present antigens to T cells, initiating immune responses.
- Serve as a critical link between innate and adaptive immunity.
Eosinophils
- Primarily involved in combating multicellular parasites and allergic reactions.
- Release cytotoxic granules to damage or destroy target cells.
Immediate Defense
- Innate immune response is the immediate defense mechanism activated upon infection in animals.
Target Cell Recognition
- Natural Killer (NK) cells recognize and destroy infected or cancerous cells in the body.
Toll-like Receptors (TLRs)
- Part of the innate immune system that detects pathogens by recognizing specific molecular patterns.
- Play a vital role in activating immune responses.
Monocytes
- Serve as precursors to macrophages and dendritic cells, involved in phagocytosis and the secretion of inflammatory factors.
Blood Cells
- Red blood cells (erythrocytes) are responsible for the transport of oxygen and carbon dioxide throughout the body.
Phagocytosis
- The process by which white blood cells, such as neutrophils and macrophages, engulf and digest microbes.
Antibodies
- Protein molecules that identify and neutralize pathogens like bacteria and viruses.
- Immunoglobulin IgG, a common antibody type, provides long-term immunity and can prevent viral infection by blocking virus entry into host cells.
Active Immunization
- Introduces antigens to stimulate an immune response and the development of memory cells for future protection against specific pathogens.
Natural Killer Cells
- A type of lymphocyte that plays a crucial role in the destruction of infected or anomalous cells without prior sensitization.
Passive Immunization
- Provides immediate immunity through the transfer of antibodies from one individual to another, usually from mother to child.
Adaptive Immune Response
- Characterized by specificity and memory, recognizing specific pathogens and mounting a stronger response upon subsequent exposure.
B Cells
- Produce antibodies in response to specific antigens and are vital for humoral immunity.
Distinguishing T Cells from B Cells
- T cells are primarily involved in cell-mediated immunity, recognizing infected or cancerous cells, while B cells focus on antibody production.
Macrophages
- Functions include phagocytosis of pathogens, debris clearance, and antigen presentation to T cells for adaptive immunity activation.
Platelets
- Primarily involved in blood clotting but also contribute to immune responses through the release of cytokines.
Extracellular Killing Cells
- Include natural killer cells and certain cytotoxic T lymphocytes, responsible for inducing apoptosis in target cells.
