Autoimmunity increases with aging indicative of reduced immune tolerance, but the mechanisms involved are poorly defined. In recent years, subsets of B cells with immunoregulatory properties have been identified in murine models of autoimmune disorders, and these cells downregulate immune responses via secretion of IL10. In humans, immature transitional B cells with a CD19(+) CD24(hi) CD38(hi) ...

BACKGROUND/AIM Increasing evidence show microRNAs (miRNAs) are engaged in hepatocellular carcinoma (HCC). The aim of this study was to investigate the role of miR-144 in HCC, as well as to identify its underlying mechanism. METHODS The expression levels of miR-144 were assessed in multiple HCC cell lines, as well as in liver tissues from patients with HCC. We further examined the effects of m...

Regulatory dendritic cells (DCs) play important roles in the induction of peripheral tolerance and control of adaptive immune response. Our previous studies demonstrate that splenic stroma can drive mature DCs to proliferate and further differentiate into a unique subset of CD11b(hi)Ia(low) regulatory DCs, which could inhibit T-cell response, program generation of immunosuppressive memory CD4 T...

OBJECTIVE Previous research indicated that miR-144-3p was associated with the regulation of the carcinogenic processes, but the role of miR-144-3p in glioblastoma (GBM) remains unclear. In this study, we aimed to analyze the role of miR-144-3p in GBM. PATIENTS AND METHODS The expression of miR-144-3p was measured in GBM tissues and adjacent non-malignant tissues using qRT-PCR. The correlation...

Water scarcity is rapidly increasing in many regions. In a novel, multi-model assessment, we examine how human interventions (HI: land use and land cover change, man-made reservoirs and human water use) affected monthly river water availability and water scarcity over the period 1971-2010. Here we show that HI drastically change the critical dimensions of water scarcity, aggravating water scarc...
