True False - True In Type I hypersensitivities IgG bind to mast cells after the second exposure IgG bind to T cells after the second exposure IgG bind to mast cells after the first exposure IgG bind to T cells after the first exposure IgE bind to mast cells after the second exposure IgE bind to T cells after the second exposure IgE bind to mast cells after the first exposure IgE bind to T cells after the first exposure - IgE...

A single lymphocyte will have a receptor with a? - Single specificity. One cell may have many receptors (~120,000) but all will recognize the same epitope. Adaptive Immune system - •Takes longer to develop (~7 days) •Is highly specific for antigens, including those associated with microbes •Uses one type od receptor to recognize many different pathogens •Primary immune response = first time the adaptive immune response is activated against a pathogen. •Secondary immune response =...

OpenStax Microbiology Test Bank Chapter 20: Laboratory Analysis of the Immune Response * = Correct answer Multiple Choice 1. Most antigens have how many epitopes? A. none B. one C. two D. more than two* 2. Which best describes monoclonal antibodies? A. They are produced in living animals only. B. They are produced in tissue cultures, using B cells extracted from living animals.* C. They are rarely used, so polyclonal antibodies are preferred. D. They can be produced in either liv...

Drug Discovery • Unlike small molecule drugs (pharmaceuticals), large molecule drugs (biopharmaceuticals) are mainly protein-based o These protein-based drugs are similar to natural biological compounds found in human body or they're fragments that mimic active part of natural compounds Discovery of Pharmaceuticals commences w/ scanning hundreds of compounds, whether w/ actual materials (irrational approach) or virtual simulations (rational approach) • Pharmaceuticals are new che...

IgE - ️️type 1 hypersensitivity -IgE antibodies act by cross-linking Fcε receptors on surfaces of immune cells -Ig's not harmful by themselves; low levels in circulation -Harm comes from interactions with Fcε receptors on effector cells -*Effector cells release granules* -*Granules contain histamine, heparin, proteases, leukotrienes, prostaglandins, chemokines -very bioactive* -Mediators act on surrounding tissues and cells to cause symptoms Basic model for immunity - ️️Anti...

A patient with a diagnosis of aplastic anemia has undergone allogenic bone marrow transplantation. Which of the following signs and symptoms would most clearly suggest the existence of graft-versus-host disease (GVHD)? Presence of a pruritic rash that has begun to slough off A patient has developed pericarditis after developing acute glomerulonephritis, a development that may be attributable to the presence of similar epitopes on group A, hemolytic streptococci and the antigens in the patien...
