主　　题：GCA Cellular signaling pathways of T cells in giant cell arteritis 

摘      要：Giant cell arteritis(GCA)is a commonly occurring large vacuities characterized by angiopathy of medium and large-sized *** granulomatous formation plays an important role in the pathogenesis of *** of T cell lineages and signaling pathways in GCA have revealed the essential role of T cells in the pathology of GCA.T cells are the dominant population present in GCA ***4+T cell subtypes that are present include Th1,Th2,Th9,Th17,follicular helper T(Tfh)cells,and regulatory T(Treg)***8 T cells can primarily differentiate into cytotoxic CD8+T lymphocytes and Treg *** instrumental part of GCA is the interplay between dendritic cells,macrophages and endothelial cells,which can result in the vascular injury and the characteristics granulomatous infiltrates *** the inflammatory loop of GCA,several signaling pathways have been reported to play an essential role in recruiting,activating and differentiating T cells,including T-cell receptor(TCR)signaling,vascular endothelial growth factor(VEGF)-Jagged-Notch signaling and the Janus kinase and signal transducer and activator of transcription(STAT)pathway(JAK-STAT)*** this review,we have focused on the role of T cells and their potential signaling mechanism(s)that are involved in the pathogenesis of GCA.A better understanding of the role of T cells mediated complicated orchestration during the homeostasis and the changes could possibly favor developments of novel treatment strategies against immunological disorders associated with GCA.
