Study Notes
Immune System Overview
- Pyrogens specifically target the hypothalamus to regulate body temperature during fevers.
- Primary response refers to the immune system's initial response to a specific pathogen.
- Secondary response is a faster and more robust reaction upon re-exposure to the same pathogen.
Immune Responses
- First and secondary responses highlight the difference in speed and intensity when encountering an antigen for the first and subsequent times.
- IgM is the first antibody produced during an immune response.
- IgG is the most prevalent antibody in blood and provides long-lasting immunity after an infection.
Immune Surveillance
- Natural killer (NK) cells play a crucial role in immune surveillance by detecting and destroying unhealthy or infected cells.
Inflammation Symptoms
- Signs of inflammation include redness, pain, and swelling, indicating an immune response to injury or infection.
Leukocyte Formation
- Leukocytes (white blood cells) are primarily formed in the red bone marrow.
Types of Immunity
- Antibody-mediated immunity is also known as humoral immunity, involving the action of antibodies against pathogens.
- Passive immunity is immunity gained from antibodies produced by another individual.
Infectious Agents
- Eukaryotic infectious agents include multicellular parasites, fungi, and protozoans.
- Molds and yeast are types of fungi, known for their role in various infections.
Bacterial Characteristics
- Bacteria are single-celled organisms typically ranging from 1 to 2 micrometers in size.
Antibody Dynamics
- The concentration of antibodies against a specific antigen in blood is termed the antibody titer.
- Fever is beneficial as it promotes interferon activity, inhibits bacterial reproduction, and accelerates tissue repair.
Immune Cells
- Alveolar macrophages are specific immune cells found in the lungs, playing a role in respiratory health.
- Common phagocytes include macrophages and neutrophils, essential for engulfing pathogens.
Hypersensitivity and Allergies
- Immunoglobulin E (IgE) is linked to acute hypersensitivities and allergic reactions.
- Phases of acute hypersensitivity reactions include sensitization, activation, and effector phases.
Immunoglobulin Insights
- IgE is notably involved in allergic reactions and response to parasitic infections.
- Immunoglobulin G (IgG) can cross the placenta, making it crucial for fetal immunity, and is the predominant antibody in lymphatic fluid.
T Cell Activation
- Cytotoxic T cell activation involves several steps, including antigen presentation, binding, stimulation by IL-2, and proliferation.
- Helper T cell activation similarly requires antigen processing by antigen-presenting cells (APCs).
Disorders and Antibody Actions
- Autoimmune disorders arise when the immune system misidentifies self-antigens as foreign.
- Neutralization occurs when antibodies coat a virus, preventing it from infecting cells.
- Antibody-mediated actions include agglutination, precipitation, and neutralization of pathogens.
Core Body Temperature and Immunity
- A core body temperature of 109 degrees Fahrenheit can be fatal, highlighting the risks of extreme fever.
Antimicrobial Substances
- Skin and mucous membranes release antimicrobial substances such as lysozyme, sebum, and immunoglobulin A to protect against pathogens.
Lymphocyte Maturation
- Lymphocytes undergo immunocompetence testing in the bone marrow and thymus gland, ensuring they can function properly in the immune response.
