The Pathogenesis of CSU

Author(s):

Key Takeaways

Autoimmune responses in CSU involve autoantibodies targeting IgE or FcεRI, leading to mast cell and basophil activation.
BTK is a key mediator in mast cell degranulation, facilitating histamine release in CSU pathogenesis.
Understanding these mechanisms is crucial for developing targeted therapies for effective CSU management.

Panelists discuss how recent insights into chronic spontaneous urticaria (CSU) pathogenesis reveal potential autoimmune responses and highlight the role of Bruton tyrosine kinase (BTK) as a key mediator in mast cell degranulation and histamine release.
