Immunobiology of Long Noncoding RNAs

lncRNAs

The discovery of long noncoding RNAs (lncRNA) has provided a new perspective on gene regulation in diverse biological contexts. lncRNAs are remarkably versatile molecules that interact with RNA, DNA, or proteins to promote or restrain the expression of protein-coding genes. Activation of immune cells is associated with dynamic changes in expression of genes, the products of which combat infectious microorganisms, ...

Slncky – evolutionary analysis across mammals reveals distinct classes of long non-coding RNAs

lncRNA

Recent advances in transcriptome sequencing have enabled the discovery of thousands of long non-coding RNAs (lncRNAs) across many species. Though several lncRNAs have been shown to play important roles in diverse biological processes, the functions and mechanisms of most lncRNAs remain unknown. Two significant obstacles lie between transcriptome sequencing and functional characterization of lncRNAs: identifying truly non-coding genes from de ...

Long noncoding RNA lincRNA-EPS as a repressor of inflammatory responses

lncRNA

Long intergenic noncoding RNAs (lincRNAs) are important regulators of gene expression. Although lincRNAs are expressed in immune cells, their functions in immunity are largely unexplored. Here, researchers at the University of Massachusetts Medical School identify an immunoregulatory lincRNA, lincRNA-EPS, that is precisely regulated in macrophages to control the expression of immune response genes (IRGs). Transcriptome analysis of macrophages from lincRNA-EPS-deficient ...

Featured Long Non-coding RNA – lincRNA-Cox2

lincRNA

An inducible program of inflammatory gene expression is central to antimicrobial defenses. Signal-dependent activation of transcription factors, transcriptional co-regulators, and chromatin modifying factors collaborate to control this response. Here, researchers from University of Massachusetts Medical School identify a long noncoding RNA that acts as a key regulator of this inflammatory response. Pattern recognition receptors such as the Toll-like receptors induce ...
