JAK/STAT信号通路参与细胞的生长、分化、凋亡和免疫调节等重要的生物学过程,是细胞因子介导的最重要的信号转导途径之一。在昆虫中,JAK/STAT是一条相对保守的信号途径,与Toll途径和Imd途径共同作为主要免疫途径以抵御病原物入侵,在昆虫免疫、激素调控和其他生理调节过程中发挥着十分重要的作用。本文介绍了细胞因子受体超家族、JAKs家族、STATs家族和JAK/STAT信号通路及其负反馈调节的作用机制,分析了寄生物、病毒和真菌感染昆虫时,JAK/STAT信号通路的重要功能及最新研究进展,并提出了JAK/STAT信号通路研究中尚待解决的问题,以期为该领域后续深入研究提供方向和参考。 相似文献

JAK/STAT signaling regulates tissue outgrowth and male germline stem cell fate in Drosophila 总被引:3,自引:0,他引:3
In multicellular organisms, biological activities are regulated by cell signaling. The various signal transduction pathways regulate cell fate, proliferation, migration, and polarity. Miscoordination of the communicative signals will lead to disasters like cancer and other fatal diseases. The JAK/STAT signal transduction pathway is one of the pathways, which was first identified in vertebrates and is highly conserved throughout evolution. Studying the JAK/STAT signal transduction pathway in Drosophila provides an excellent opportunity to understand the molecular mechanism of the cell regulation during development and tumor formation. In this review, we discuss the general overview of JAK/STAT signaling in Drosophila with respect to its functions in the eye development and stem cell fate determination. 相似文献

Role of the JAK/STAT signal transduction pathway in the regulation of gene expression in CNS 总被引:11,自引:0,他引:11

Over the last 20 years the JAK/STAT signal transduction pathway has been extensively studied. An enormous amount of data on different cell signal transduction pathways is now available. The JAK/STAT signal transduction pathway is one of the intracellular signaling pathways activated by cytokines and growth factors that was first studied in the hematopoietic system, but recent data demonstrate that this signal transduction is also greatly utilized by other systems. The JAK/STAT pathway is a signaling cascade that links the activation of specific cell membrane receptors to nuclear gene expression. This review is focused on the role of JAK/STAT signal transduction pathway activation in the central nervous system (CNS). 相似文献

The JAK/STAT pathway and Drosophila development. 总被引:1,自引:0,他引:1

The JAK/STAT signal transduction pathway plays a critical role in mammalian cells, particularly in hematopoiesis and immune responses. Several components of this pathway have been identified and characterized in Drosophila. Mutational analyses of these components have revealed a number of interesting developmental roles, and provide a mechanism to identify other interacting molecules and pathways. Hence, the JAK/STAT pathway in Drosophila serves as an attractive model for in vivo functional analyses of JAK/STAT signaling. 相似文献

The JAK/STAT pathway was originally identified in mammals. Studies of this pathway in the mouse have revealed that JAK/STAT signaling plays a central role during hematopoeisis and other developmental processes. The role of JAK/STAT signaling in blood appears to be conserved throughout evolution, as it is also required during fly hematopoeisis. Studies in Dictyostelium, Drosophila, and zebrafish have shown that the JAK/STAT pathway is also required in an unusually broad set of developmental decisions, including cell proliferation, cell fate determination, cell migration, planar polarity, convergent extension, and immunity. There is increasing evidence that the versatility of this pathway relies on its cooperation with other signal transduction pathways. In this review, we discuss the components of the JAK/STAT pathway in model organisms and what is known about its requirement in cellular and developmental processes. In particular, we emphasize recent insights into the role that this pathway plays in the control of cell movement. 相似文献
