Study Notes
Overview of the Immune System
- The immune system consists of two main components: innate immunity and adaptive immunity, both essential for protecting the body from infections.
- Innate Immunity: The body's first line of defense, responding quickly to pathogens without prior exposure.
Components of the Immune System
- Organs: Includes lymph nodes, spleen, thymus, and bone marrow, each playing vital roles in immune function.
- Cells: Comprised primarily of lymphocytes (B cells and T cells), phagocytes, and other immune cells that directly combat pathogens.
- Molecules: Encompasses antibodies, cytokines, and various proteins involved in immune signaling and response.
Pattern Recognition Receptors (PRRs)
- PRRs help identify pathogens by recognizing specific features:
- Toll-like Receptors (TLRs): Recognize broad patterns in pathogens to initiate immune responses.
- NOD-like Receptors (NLRs): Detect intracellular pathogens and trigger appropriate immune signaling.
- C-type Lectin Receptors (CLRs): Bind to carbohydrates on pathogens, playing a role in immune recognition.
Mechanisms of Innate Immunity
- Inflammation: A protective response that delivers immune cells to the site of infection, promoting healing and defense.
- Phagocytosis: Process whereby phagocytes engulf and digest pathogens.
- Complement System: A group of proteins that enhances the ability of antibodies and phagocytes to clear pathogens from an organism.
Adaptive Immunity
- B Cells: Recognize circulating antigens, which are substances that provoke an immune response, and produce specific antibodies to neutralize these antigens.
-
T Cells: Identify processed antigens presented by other cells; crucial for targeting infected or cancerous cells.
- T Cell Receptor (TCR): A molecule on T cells that allows for recognition of antigens presented by Major Histocompatibility Complex (MHC) molecules.
- Specificity: Lymphocytes have unique, antigen-specific receptors, enabling nuanced recognition of diverse pathogens, ensuring a tailored immune response.
