UV-induced Treg cells
Dendritic cells (DCs) are the master regulators of T cell recirculation, according to a study by Mora et al. on page 303. Memory T cells—thought to be programmed to return to the location in which they first encountered antigen—can be rerouted by an encounter with a DC from another location. Previous studies have shown that memory T cells express a characteristic array of adhesion molecules and...
متن کاملTreg cells to the rescue.
In this issue of Arthritis & Rheumatism, Kong and colleagues report that collagen-induced arthritis (CIA), a mouse model of rheumatoid arthritis (RA), can be effectively treated by systemic injection of Treg cells (1). These results raise several questions: Are there defects in Treg cell numbers or function in RA? How should Treg cells be collected, generated, or expanded for use in the treatme...
متن کاملTCR signals fuel Treg cells
Regulatory T (T reg) cells safeguard against autoimmunity and overshooting inflammation. During their development in the thymus, T reg cells are selected by stronger autoantigenic T cell receptor (TCR) signals than conventional T cells. These TCR signals are critically important for the initiation of two key lineage defining events, namely induction of the transcription factor Foxp3 and hypomet...
متن کاملMicroRNA-155 Modulates Treg and Th17 Cells Differentiation and Th17 Cell Function by Targeting SOCS1
MicroRNA (miR)-155 is a critical player in both innate and adaptive immune responses. It can influence CD4(+) T cell lineage choice. To clarify the role of miR-155 in CD4(+) CD25(+) regulatory T (Treg)/T helper (Th)17 cell differentiation and function, as well as the mechanism involved, we performed gain-and loss-of-function analysis by transfection pre-miR-155 and anti-miR-155 into purified CD...
متن کاملmiR-142-3p restricts cAMP production in CD4+CD25- T cells and CD4+CD25+ TREG cells by targeting AC9 mRNA.
Cyclic AMP (cAMP) is a ubiquitous second messenger that regulates diverse cellular functions. It has been found that CD4(+)CD25(+) regulatory T (T(REG)) cells exert their suppressor function by transferring cAMP to responder T cells. Here, we show that miR-142-3p regulates the production of cAMP by targeting adenylyl cyclase (AC) 9 messenger RNA in CD4(+)CD25(-) T cells and CD4(+)CD25(+) T(REG)...
