Understanding human mast cells: lesson from therapies for allergic …
网页2021年10月5日 · Mast cells have crucial roles in allergic and other inflammatory diseases. Preclinical approaches provide circumstantial evidence for mast cell involvement in many diseases, but these...
Mast Cell Activation Syndrome (MCAS) - American Academy of Allergy …
网页In allergic reactions, this release occurs when the allergy antibody IgE, which is present on the mast cell surfaces, binds to proteins that cause allergies, called allergens. This triggering is called activation, and the release of these mediators is called degranulation.
Targeting Mast Cells in Allergic Disease: Current Therapies and …
网页2022年9月27日 · Mast cells are critical effectors of allergic inflammation. Their secreted mediators and the receptors for these mediators have long been the target of allergy therapy. Recent drugs have moved a step earlier in mast cell activation, blocking IgE, IL-4, and IL-13 interactions with their receptors.
The role of human mast cells in allergy and asthma - PMC
网页2022年3月10日 · In asthma and allergic diseases, mast cells are stimulated by the allergen-IgE complex to release a variety of de novo synthesized and granularly stored mediators. These mediators released by mast cells are the main drivers of inflammation, as they include cytokines, lipid mediators, and proteases …
Role of mast cells in allergic and non-allergic immune ... - Nature

Mast cells in allergy and infection: Versatile effector and …
网页While mast cells are best known for their role in IgE-associated allergic disorders, mast cells can also exacerbate models of autoimmunity, enhance the sensitization and/or effector phases of certain cutaneous contact hypersensitivity (CHS) responses, and increase inflammation and mortality during some severe bacterial infections.
The role of mast cells in allergic inflammation - PubMed
网页The aim of this review is to describe the role of mast cells in allergic inflammation. Mast cells interact directly with bacteria and appear to play a vital role in host defense against pathogens. Drugs, such as glucocorticoids, cyclosporine and cromolyn have been shown to have inhibitory effects on mast cell degranulation and mediator release.
The role of human mast cells in allergy and asthma
网页2022年3月10日 · Mast cells arise in the bone marrow as progenitor cells and complete their differentiation in tissues exposed to the external environment, such as the skin and respiratory tract, and are among the first to respond to bacterial and parasitic infections.
Mast Cells: Anatomy, Function & Diseases - Cleveland Clinic
网页2024年5月16日 · Overview. What are mast cells? Mast cells are a part of your immune system. They’re made in your bone marrow, then move through your bloodstream into your tissues. The mature mast cells live in tissues throughout your body to help protect you from hazards around you. They can help fight infections and regulate your organs.
