Abstract
Allergy is a common hypersensitivity disorder of the immune system, which, along with other factors, is also subjected to regulation by microRNAs. The most common allergic diseases are allergic rhinitis, asthma, atopic dermatitis, and food allergy, which all are multifactorial and very heterogeneous conditions, highlighting the need for more individualized treatment techniques. More particular key questions in relation to allergic diseases are how microRNAs influence the differentiation, polarization, plasticity and functions of T helper and other immune cells, as well as the development of immune tolerance. In addition, microRNAs can affect allergic inflammation and tissue remodeling through their functions in epithelial and other tissue cells. Among immune system-related microRNAs, miR-21, miR-146a, and miR-155 are the most intensively studied and have convincingly been demonstrated to regulate immune responses and tissue inflammation in allergic diseases. Further characterization of microRNA functions is important, as similar to other conditions, the modulation of microRNA expression could potentially be used for therapeutic purposes in allergic diseases in the future. In addition, miRNAs could be implemented as biomarkers for endotyping complex allergic conditions.

Epigenetics and allergy: from basic mechanisms to clinical applications

TL;DR: The potential of epigenetic changes for various clinical applications is shown: as diagnostic tools, to assess tolerance following immunotherapy or possibly predict the success of therapy at an early time point and new technological advances such as epigenome editing and DNAzymes will allow targeted alterations of the epigenome in the future and provide novel therapeutic tools.

NF-κB-dependent induction of microRNA miR-146, an inhibitor targeted to signaling proteins of innate immune responses

TL;DR: A role is proposed for miR-146 in control of Toll-like receptor and cytokine signaling through a negative feedback regulation loop involving down-regulation of IL-1 receptor-associated kinase 1 and TNF receptor- associated factor 6 protein levels.

Argonaute2 complexes carry a population of circulating microRNAs independent of vesicles in human plasma

TL;DR: Identification of extracellular Ago2–miRNA complexes in plasma raises the possibility that cells release a functional miRNA-induced silencing complex into the circulation, and reveals two populations of circulating miRNAs and suggest that circulating Ago2 complexes are a mechanism responsible for the stability of plasma mi RNAs.

MicroRNAs are transported in plasma and delivered to recipient cells by high-density lipoproteins

TL;DR: Evidence that high-density lipoprotein (HDL) transports endogenous miRNAs and delivers them to recipient cells with functional targeting capabilities is presented, indicating that HDL participates in a mechanism of intercellular communication involving the transport and delivery of miRNA.

Asthma phenotypes: the evolution from clinical to molecular approaches

TL;DR: Ongoing studies of large-scale, molecularly and genetically focused and extensively clinically characterized cohorts of asthma should enhance the ability to molecularly understand these phenotypes and lead to more targeted and personalized approaches to asthma therapy.
