Pseudo-allergic reaction caused by Qingkailing injection partially via the PI3K-Rac1 signaling pathway in RBL-2H3 cells.

ABSTRACT: Qingkailing injection (QKLI) is a kind of multi-component traditional Chinese medicine injection. It has been widely used in clinical practice, but in recent years, it has caused more and more adverse reactions, mainly manifested as pseudo-allergic symptoms. To explore the potential mechanism of the pseudo-allergic reaction by QKLI, basophilic leukemia cell line 2H3 (RBL-2H3) was chosen. The results showed that QKLI at doses of 5, 10 and 20 mL L^-1 activated phosphoinositide 3-kinase (PI3K) activity and also increased the levels of Ras-related C3 botulinum toxin substrate 1 (Rac1), p21 protein-activated kinase 1 (Pak1), LIM kinase (Limk1) and cofilin (an actin polymerization regulator) proteins. What's more, QKLI aggravated the depolymerization of F-actin. NSC23766, a Rac1 inhibi
