Upon allergen stimulation, sensitized basophils express the activation and degranulation marker CD63.5 We could show that baricitinib significantly suppressed allergen-mediated basophil activation and degranulation in a dose-dependent manner in vitro (Figure 1B and C, Figure S1, Table S1). JAK1/2 inhibitor but not IL-4 receptor alpha antibody suppresses allergen-mediated activation of human basophils in vitro. [Extracted from the article]
