IgG AND IgM and soluble antigen What is type IV hypersensitvity? T Cells and soluble or cell-bound antigen What is type I hypersensitivity mechanism of activation? -Allergen-specific IgE antibodies bind to mast cells via their Fc receptor. -When the specific allerg...

HMX Immunology Practice Questions with 100% Correct Answers | Latest Version 2024 | Verified Which cells are tissue resident sentinel cells - mast cell, macrophage, dendritic cell Which 2 cells are circulating blood cells that will enter tissue in response to inflammation? - Neutrophils, Monocytes Mast cell - Cells that release chemicals (such as histamine) that promote inflammation. Neutrophil - Most abundant leukocyte, increase due to bacterial infection, burns, and stress. Pha...

Definitive host - Host in which the parasite reaches sexual maturity - sexual reproduction takes place in the host Intermediate host - Host in which asexual reproduction or larval development takes place - allows continuation of life cycle Vector - transmitting agent What are the key factors that would lead you to suspect that a parasite (rather than a virus or bacterium) was responsible for some gastrointestinal illness - 1. Potential for infection (travel history) 2. La...

What is type I hypersensitivity immune reactant, antigen form, mechanism of activation, and examples? - Correct Answer reactant: IgE Antigen form: soluble antigen Mechansim: -Allergen-specific IgE antibodies bind to mast cells via their Fc receptor. -When the specific allergen binds to the IgE, cross-linking of IgE induces degranulation of mast cells. Examples: - Local and systemic anaphylaxis -Seasonal hay fever - Food allergies - Drug allergies (fastest) What is type II hype...
