Which type of hypersensitivity reaction is this? - Type 1 Your patient has diagnosis of Grave's disease. Which type of Hypersensitivity reaction is this? - Type 2 Which of the following is a type III hypersensitivity reaction? - Glomerulonephritis Which of the following statement is true regarding Type IV Reactions? - The reaction is mediated by T lymphocytes Which of the following statements are true regarding exotoxins? - damage cell membranes, activate second messengers, inhibit protein synthesis immunity is produced by an individual after natural exposure to an antigen or after immunization - Active harryson immunity produces immunoglobulins that bind to antigens and neutralize their effects - Humoral stimulates the proliferation of T cells and B cells during inflammation - Interleukins Catecholamines decrease which of the following immune system cells during chronic stress? - Natural Killer cells interfere with insulin signaling leading to insulin resistance in stress, obesity, and Type 2 Diabetes. - Pro-inflammatory cytokines what type of immunity is produced when an immunoglobulin crosses the placenta? - Passive acquired the normal microbiome - The body's surfaces are colonized with a variety of microorganisms, Surfaces, such as skin and mucous membranes of eyes, upper and lower GI tracts, urethra and vagina are colonized by a combination of bacteria and fungi that are unique to a particular location and individual. If immunocompromised the microbiome can lead to - opportunistic infections or loss of integrity of the body surface areas. Type 1 hypersensitivity example - seasonal rhinitis Type 1 hypersensitivity - IgE mediated, binds to mast cell which causes release of histamine and other inflammatory cytokines Eosinphils are active in which hypersensitivity? - Type 1 Histamine binds to _ to cause allergic reaction - H1 receptors Where are H1 receptors found? - smooth muscle, endothelium, bronchial lining, oral mucosa act to prevent over reactions in the smooth muscle contractions brought on by histamine binding to H1 receptors - H2 receptors histamine binding to H1 causes - smooth muscle contraction histamine binding to H2 causes - smooth muscle relaxation, avoids anaphylaxis H2 blocker examples - pepcid H1 is - pro-inflammatory H2 is - antiinflammatory
