Expanding the Immunologic and Neuronal Landscape of IgE‐Mediated Anaphylaxis

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Anaphylaxis is a life‐threatening immunoglobulin E (IgE)‐mediated type I hypersensitivity reaction with rising prevalence and burden. It involves mast cell degranulation upon cross‐linking of antigen on mast cell‐bound IgE. Mechanisms of IgE‐mediated anaphylaxis remain incompletely understood, particularly the induction of systemic symptoms ...
