Investigation of the interleukin (IL)-4/IL-4 receptor system in promyelocytic leukaemia PLB-985 cells during differentiation toward neutrophil-like phenotype: mechanism involved in IL-4-induced SOCS3 protein expression.

Abstract excerpt

The interleukin 4 (IL-4)/IL-4 receptor (IL-4R) system in promyelocytes is not well documented. Here, we used promyelocytic leukaemia PLB-985 cells differentiated with dimethylsulfoxide (PLB-985D) toward neutrophil-like phenotype to investigate the IL-4/IL-4R system. PLB-985 cells did not express CD132 (gammac) but expressed the complete IL-4 type II receptor (IL-4Ralpha and IL-13Ralpha1). Moreover, PLB-985 cells...
