PATHOPHYSIOLOGY - MODULE 2 - EXAM 1 QUESTIONS WITH 100% CORRECT ANSWERS 2022/2023 Answers highlighted Define hypersensitivity Altered immunologic response to an antigen that results in disease or damage to individual (strong genetic linkage) 2 alternate names for type 1 hypersensitivity Immediate hypersensitivity or IgE mediated reactions most common allergic reactions are type 1 Mechanisms of type 1 response 1. Sensitizing exposure 2. Re exposure (immediate response and longer term...

Innate immunity - the immunity we are born with Immune response: 3 levels/lines of protection - 1st line: physical, mechanical, & biochemical barriers 2nd line: the inflammatory response 3rd line: lymphocyte production most important immune defense - intact skin and mucous membranes (impermeable barrier) PAMP - pathogen associated molecular pattern surfaces of bacteria, viruses, and other microbes are covered with many foreign proteins foreign DAMP - damage associated mol...

What are in vitro tests used for? - Answer Basic principles of tests used by scientists / physicians to study the immune system and responses to disease What is serology? - Answer - Study of in vitro interactions with serum (clotted blood and serous fluid is further analyzed) - Plasma is blood drawn (citrate tube), not clotted, and cells removed What are precipitation tests? - Answer - Soluble antigen with antibody - Needs optimal concentrations for precipitins (visible Ag-Ab compl...

The most common cause of AHTR? correct answers ABO incompatibility What type of HSR is AHTR? correct answers Type II (IgG and IgM autoantibodies and complement activation (humoral components), NK cells, eosinophils, neutrophils, and macrophages (cellular components) - MC seen in autoimmune hemolytic anemia and Goodpasture syndrome) What is the primary mediators of a type I HSR? correct answers IgE (humoral component), basophils and mast cells (cellular components) - MC in anaphylaxis and a...

allergic rhinitis pathophysiology - correct answer APCs (dendritics) at mucosal surfaces present peptides from allergens to MHC-II = ligand for naive CD4 = Th2 activation and cytokine secretion / B cell isotype switching = IgE and eosino/mast/neutro proliferation IgE binds to mast cells / basophils allergic rhinitis early reaction - correct answer w/in 30min, type I HS IgE binds mast cells = s...

Immune Response - correct answer can be divided into two major classifications: humoral and cell-mediated Antigen (Ag) - correct answer A molecule which elicits a specific immune response when introduced into an animal. Antigenic (immunogenic) substances - correct answer Generally large molecules (>10,000 daltons in molecular weight), Structurally complex (proteins are usually very antigenic), Accessible ...

Roles of complement system correct answers - direct lysis of cells, bacteria and enveloped viruses -assist with opsonization to facilitate phagocytosis -produce peptide fragment split products which can mediate inflammatory and immune responses classical pathway correct answers -a series of proteins called factors amplifies the immune response -factors circulate in inactive forms -upon activation they attach in an exact sequence CP recognition correct answers (C1= C1q-C1r-C1s) CP en...
