Mast Cells in Allergic Asthma - Anaphylactic Shock

Learn about the role of mast cells in allergic asthma and anaphylactic shock in this comprehensive 36-minute video lecture. Explore the pathophysiology of type 1 hypersensitivity reactions, including the body's response to allergens like pollen and penicillin. Understand the process of sensitization during first exposure, and the cascade of events during subsequent exposures leading to symptoms. Discover how mast cell degranulation releases primary and secondary mediators, causing bronchial constriction, mucosal edema, and systemic effects. Gain insights into the clinical manifestations of allergic asthma and anaphylaxis, including dyspnea, wheezing, skin reactions, and circulatory shock. Enhance your knowledge of immunology, histology, and the critical role of mast cells in allergic responses.

Mast Cells in Allergic Asthma & Anaphylactic Shock
Mast Cells are present in all body Connective Tissues except CNS.
ALLERGIC ASTHMA:
FIRST EXPOSURE TO POLLENS:
SECOND EXPOSURE TO POLLENS:
SECONDARY MEDIATORS OF ALLERGY are formed by Mast Cells after exposure;
PENICILLIN ALLERGY & ANAPHYLACTIC SHOCK:
