It is becoming increasingly clear that there are unique sets of miRNAs that have distinct governing roles in several aspects of both innate and adaptive immune responses. In addition, new tools allow selective modulation of the expression of individual miRNAs, both in vitro and in vivo. Here, we summarize recent advances in our understanding of how miRNAs drive the activity of immune cells, and how...
MicroRNAs (miRNAs) are small non-coding RNAs that regulate various aspects of gene expression in physiology and development. Links between miRNAs and the initiation and progression of human diseases are becoming increasingly apparent. The development of methods to detect the subcellular and tissue localization of miRNAs is essential for understanding their biological role in homeostasis. In this...
Background: Both pleiotropic and ubiquitous, microRNAs (miRNAs) exert control over a wide range of cellular functions. They have been detected in virtually every extracellular fluid in the mammalian body, and many circulate substantial anatomical distances in plasma. Thus, secreted miRNAs are valuable not only as diagnostic tools but also may serve as novel biological effectors that can be transmitted...
This article reviews the current strategies and challenges of diagnosing pancreatic cystic lesions, and presents an overview of molecular tools that are available to enhance diagnostic accuracy. Specifically, we highlight the emergence of microRNAs (miRNAs) as diagnostic markers. miRNA signatures have been reported for both solid tissue and biofluid specimens, including cyst fluid, collected from...
