Background: Hepatitis C virus (HCV) is a life threatening human pathogen. It has been found that miRNA146a regulates innate immunity, inflammatory response and antiviral pathway. We evaluated miRNA146a expression by real-time PCR and IL-1 receptor associated kinase 1 (IRAK1) and TNF receptor-associated factor 6 (TRAF6) levels by ELISA in serum of 36 HCV viremia patients and 42 age and gender matched healthy controls.
Results: miRNA146a expression was significantly higher in HCV patients with a best cut off value 1.63 to discriminate between HCV patients and healthy controls. Meanwhile, it was negatively correlated to IRAK1 and TRAF6 levels and positively correlated to viral load in HCV patients.
Conclusions: miRNA146a has a potential role in HCV infection and viral replication through IRAK1 and TRAF6. It can also serve as a new screening method for HCV.

Objective: The present study investigated the relationship between maternal periodontal disease, insulin resistance, activation of inflammatory pathways and epigenetic modifications in adult offspring.
Design: Therefore, female Wistar rats were divided into control and experimental groups. Seven days after the induction of periodontal disease, female rats from both groups were mated with healthy male rats.
Mesenchymal stem cell-derived extracellular vesicles reduce inflammatory responses to SARS-CoV-2 and Influenza viral proteins via miR-146a/NF-κB pathway.

The risk of severe disease caused by co-infection with SARS-CoV-2 and influenza virus (IAV) raises an annual concern for global public health. Extracellular vesicles (EV) derived from mesenchymal stem cells (MSC) possess anti-inflammatory properties that can attenuate the inflammatory cytokine levels induced by viral infection. However, the effects of MSC-EV treatment on SARS-CoV-2 and IAV co-infection have not been elucidated.

Interleukin-1 Receptor Associated Kinase 1 (IRAK1) is a serine/threonine kinase that plays a critical role as a signaling transducer of the activated Toll-like receptor (TLR)/Interleukin-1 receptor (IL-1R) signaling pathway in both immune cells and cancer cells. Upon hyperphosphorylation by IRAK4, IRAK1 forms a complex with TRAF6, which results in the eventual activation of the NF-κB and MAPK pathways. IRAK1 can translocate to the nucleus where it phosphorylates STAT3 transcription factor, leading to enhanced IL-10 gene expression.

The high-glucose conditions caused by diabetes mellitus (DM) exert several effects on cells, including inflammation. miR-146a, a kind of miRNA, is involved in inflammation and may be regulated mutually with reactive oxygen species (ROS), which are produced under high-glucose conditions. In the present study, we used human periodontal ligament cells (hPDLCs) to determine the effects of the high-glucose conditions of miR-146a and their involvement in the regulation of oxidative stress and inflammatory cytokines using Western blotting, PCR, ELISA and other methods.

Introduction: Allergic asthma is prevalent in children, with Dermatophagoides farinae as a common indoor allergen. Current treatments for allergic airway inflammation are limited and carry risks. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) show promise as a cell-free therapeutic approach.
