In the progression of various diseases, inflammation has a critical role. Chronic persistent inflammation is a pivotal trigger of fibrosis. Several microRNAs (miRNAs) participate in inflammation and fibrosis. In recent years, it has been proved that miRNAs are a critical link in physiological and pathological processes. Among them, the miRNA miR‑146a has a pivotal role in the immune system and acquired immunity, making it one of the most studied miRNAs. Due to its essential roles at the molecular and cellular levels, it has broad application prospects in precision medicine. The present comprehensive review focused on the mechanisms of miR‑146a and its application strategies in inflammation and fibrosis, discussing its therapeutic potential. The main signaling pathways through which miR‑146a regulates inflammation and fibrosis and their relationships were covered. Furthermore, the functions and effects of miR‑146a in specific cells, which may join in the process of inflammation and fibrosis, were outlined. Application strategies were also summarized according to recent studies based on these mechanisms.

Background And Objective: Asthma-COPD overlap (ACO) is characterized by patients exhibiting features of both asthma and COPD. Currently, there is no specific treatment for ACO. This study aimed to investigate the therapeutic potential of targeting CD131, a shared receptor subunit for IL-3, IL-5 and GM-CSF, in ACO development and in preventing acute viral exacerbations.

Graphene quantum dots (GQDs) have received much attention for their biomedical applications, such as bioimaging and drug delivery. Additionally, they have antioxidant and anti-inflammatory properties. We used GQDs to treat renal fibrosis and confirmed their ability to protect renal cells from excessive oxidative stress in vitro and in vivo.

Objective: To investigate baseline and change of pulmonary damage biomarkers (serum Krebs von den Lungen 6 [KL-6], human surfactant protein D [hSP-D], and matrix metalloproteinase 7 [MMP-7]) with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) progression.
Methods: In the Korean Rheumatoid Arthritis Interstitial Lung Disease (KORAIL) cohort, a prospective cohort, we enrolled patients with RA and ILD confirmed by chest computed tomography imaging and followed annually. ILD progression was defined as worsening in physiological and radiological domains of the 2022 American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society guideline for progressive pulmonary fibrosis (PPF).

High altitude characterized by the low partial pressure of the oxygen is a life-threatening condition that contributes to the development of acute pulmonary edema and hypoxic lung injury. In this study, we aimed to investigate the contribution of some inflammatory and oxidative stress markers along with antioxidant system enzymes in the pathogenesis of HAPE (high-altitude pulmonary edema) formation. We incorporated the study on 42 male rats to unravel the role of mast cells (MCs) and TNF-α in the lung after the effect of acute hypobaric hypoxia.
