Summary: This review summarizes and analyzes the etiology and pathogenesis of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). The incidence of RA-ILD increases with age and is higher in men, and is also associated with lifestyle factors such as smoking and exposure to pollutants. The presence of anti-cyclic citrullinated peptide antibody, high RA disease activity, and rheumatoid factor positivity increase the risk of RA-ILD.

Summary: The modifications in genomic DNA methylation play a crucial role in regulating normal and pathological cellular processes, and are associated with the development of diseases such as atherogenesis, cancers, and chronic kidney disease (CKD). Altered DNA methylation can affect the progression of renal disease by modulating the expression of pro-inflammatory and pro-fibrotic genes, as well as genes essential for kidney development and function. Understanding the genetic-epigenetic profile is important for unraveling the processes underlying CKD development and improving the ability to identify individuals at risk and choose appropriate disease management.

Summary: This study aimed to investigate the regulation of pro-inflammatory mediators, especially S100 proteins, in rheumatoid arthritis (RA) and identify potential biomarkers of high disease activity. Through RNA sequencing analysis, it was found that RA monocytes exhibited significantly increased expression of S100 proteins, TNF, and IL-8 genes. Moreover, S100A8, S100A11, and S100A12 proteins were significantly upregulated in RA patients, especially in early RA, and could serve as better biomarkers of disease activity.

Summary: The development of novel therapeutics for Parkinson's disease (PD) is a serious concern as the burden of PD continues to increase. Studies have found that epigenetics plays an important role in PD and several dysregulated epigenetic mechanisms have been identified. These mechanisms are regulated by miRNAs which have the potential to be novel therapeutic targets as well as biomarkers for PD.

Summary: Researchers have developed informatics infrastructure and methods for DNA methylation analysis in multiple species, including domesticated animals and laboratory mice. They have created a data-driven analysis pipeline for species inference, genome-specific data preprocessing, and regression modeling. Comparative analysis has revealed the dynamics of epigenome evolution in different genomic territories and tissue types, and specific methylation differences related to mouse strain phenotypes have been identified. These methods expand epigenome research to a wide range of species by streamlining DNA methylation array analysis for undesigned genomes.

Summary: Using bidirectional Mendelian randomisation (MR), it was found that gastro-oesophageal reflux disease (GORD) increases the risk of idiopathic pulmonary fibrosis (IPF), but there is no evidence that IPF increases the risk of GORD. This suggests that GORD should be considered in future studies of IPF risk and the mechanisms underlying the effect of GORD on IPF should also be investigated.

Summary: Lloyd and Saglani provide an overview of the immunology of respiratory infections in early life and how it impacts lifelong lung health. Respiratory infections are common in infants and young children, and their effects during this developmental stage can have long-term consequences. The immune system and microbiome in the respiratory tract develop simultaneously, and any disruption to this development can have implications for lung health throughout one's life. The authors emphasize the importance of understanding the molecular mechanisms underlying the interplay between immune and structural cells in the lung and the local microorganisms to mitigate harmful effects and restore lung immune health.

Summary: This study found that small extracellular vesicles (sEVs) released by bronchial epithelial cells in IPF patients can transfer senescence to neighboring healthy cells, promoting the development of IPF. The researchers also identified several differentially expressed miRNAs in the sEVs released by IPF-diseased bronchial epithelial cells. These findings contribute to a better understanding of the pathogenesis of IPF.
