Bruton tyrosine kinase (Btk) in neutrophils is indispensable for initiating and maintaining skin inflammation in a model of pemphigoid diseases

British Journal of Pharmacology, EarlyView.
Background and Purpose Bruton tyrosine kinase (Btk) is essential for B cell function. Its role in myeloid cells is less understood. Greater insights into Btk significance in myeloid cells are needed to evaluate its potential as a therapeutic target during the effector phase of antibody‐induced autoimmune diseases, where inhibiting autoantibody ...
