Study Notes
Immune Response and Inflammation: Key Concepts
- Fever serves to stimulate phagocytes, increase metabolism, and decrease microorganism ability
- Inflammation is a defense mechanism against tissue injury, infection, or allergy, characterized by heat, redness, swelling, and pain
- Inflammatory response involves the release of histamines and increases oxygen and blood flow to the affected area
- Inflammation aims to localize infection, neutralize toxins, and repair damaged tissues through the formation of inflammatory exudate
- Lymphatic system and lymph vessels play a crucial role in immune function
- Third line of immune defense involves T-cells and B-cells, which are lymphocytes that are produced in the bone marrow
- Antigens, such as bacteria and viruses, trigger an immune response
- Clinical signs of infection include an increase in white blood cells, fever, anorexia, malaise, and purulent exudate
- Treatment for infection may involve empirical treatment based on clinical judgment
- Virulence of a pathogen and the dose of exposure are key factors in the chain of infection
- Activation of specific immunity involves B-cells and T-cells originating in the bone marrow and the presentation of antigens
- Interleukins, produced by helper T-cells, stimulate the immune system and activate different types of T-cells and B-cells to fight pathogens
Immunity and Immune Response Overview
- Immunity is categorized into two types: innate (present at birth) and adaptive (developed over time).
- Adaptive immunity is further divided into natural (ready-made antibodies), active (contact with disease), and passive (acquired from an external source).
- Artificially acquired active immunity is achieved through vaccination, using weakened or killed organisms or toxins.
- Passive immunity involves receiving antibodies from an external source, without developing memory cells.
- RhoGAM is administered to prevent RH incompatibility issues during pregnancy, ensuring the mother does not produce antibodies against the baby’s red blood cells.
- Autoimmunity occurs when the body attacks its own cells, leading to chronic and degenerative diseases like rheumatoid arthritis and lupus.
- Immune deficiency can be congenital or acquired, such as in HIV infection, organ transplant, or chemotherapy, leading to a weakened immune response.
- Chemotherapy targets rapidly multiplying cells, including white blood cells, leaving the patient susceptible to opportunistic infections.
- Allergies involve the immune system mistaking harmless substances for pathogens, leading to inflammation and histamine release.
- Anaphylactic shock can occur in severe allergic reactions, leading to arterial dilation and increased capillary permeability.
- Epinephrine is used to treat anaphylactic shock by dilating the airway and constricting blood vessels.
- Desensitization therapy, such as allergy shots, can help in reducing allergic reactions over time.
