摘要
STAT (signal transducers and activators of transcription) family, consisting of seven members, is involved in cytokine signal transduction. Biologic;ll roles of each STAT family protein have now been elucidated through studies of gene targeted mice. Stat1 knockout mice are defective in interferon-mediated functions. Stat4 and Stat6 knockout mice show defective responses to IL-12. and IL-4, respectively. Analyses of Stat5a and Stat5b knockout mice reveal important roles in prolactin-mediated mammary gland development and growth hormone-mediated induction of sexual dimorphism, respectively. Conditional knockout study of Stat3 demonstrates its critical roles in cytokine-mediated functions in several tissues, including T cells, macrophages, skin, and mammary gland.
