An R-loop is a complex nucleic acid structure consisting of an RNA-DNA hybrid and an associated single-stranded DNA. This structure plays an important role in many biological processes, including gene regulation, DNA replication, and maintenance of genome stability. Under physiological conditions, the R-loop is in a dynamic balance of generation and decomposition, which is a complex process involving multiple mechanisms of its formation, clearance, and regulation. Emerging evidence indicates that R-loops can drive inflammation and participate in immune processes. This review summarizes immune dysregulation resulting from impaired R-loop clearance and analyzes recent advances in computational methods for R-loop regulation, aiming to identify new avenues for developing R-loop-targeted immunotherapies.

Numerous clinical and epidemiological studies have demonstrated altered immune activity in adult depression patients, yet comparable data in youth are scarce. This study investigated the relationship between depression severity and peripheral immune measures in a clinical sample of children and adolescents. We analyzed 1198 blood samples from 819 patients (age range: 8-18 years) diagnosed with mild, moderate, or severe depression disorder using ICD-10 criteria.

Metaflammation, a chronic immune response triggered by metabolic dysregulation, poses significant threats to gut-liver homeostasis in aquaculture species. To understand the progression of metaflammation, it is crucial to examine the role of SOCS8 deficiency in socs8 zebrafish, as this species may serve as a disease model for metabolic disorders due to the gradual dysregulation of immunity, metabolism, and the gut microbiota observed in them. This study examines the immune-metabolic crosstalk in grass carp, subjected to soybean meal-induced enteritis, and in socs8 zebrafish under genetic and dietary stress.

The immune system is the ultimate defense against diseases and its dysregulated homeostasis greatly threatens human health. Natural polysaccharides have a variety of biological activities and show promising applications in immunomodulation. In this study, we characterized the structure of the polysaccharide IRPS-TE-3 from Isatidis Radix using morphological analysis, molecular weight analysis, monosaccharide composition analysis, methylation analysis and nuclear magnetic resonance spectroscopy.

Cancer is a complex and heterogeneous disease characterized by the accumulation of genetic and epigenetic alterations that drive uncontrolled cellular proliferation and survival. This review provides a comprehensive overview of key cancer driver genes, including oncogenes such as KRAS and PIK3CA, as well as tumor suppressor genes like TP53, PTEN, and CDKN2A, highlighting their molecular mechanisms and roles across various types of cancer. Leveraging insights from large-scale cancer genome initiatives and whole-genome sequencing, we examine the landscape of somatic mutations and their association with hallmark cancer pathways, including cell cycle regulation, apoptosis, metabolic reprogramming, and immune evasion.

Glyphosate-based herbicides are the most widely applied pesticides worldwide and have been implicated in the development of certain hematologic malignancies; however, the underlying biological mechanisms are not well-understood. High lifetime use of glyphosate-based herbicides, hereafter referred to as glyphosate, was previously associated with mosaic loss of chromosome Y (mLOY), a biomarker of genomic instability potentially linked to cancer and immune dysregulation, in circulating blood of male farmers from a subcohort of the Agricultural Health Study (AHS). Here, we further investigated the association between glyphosate use and mLOY using buccal-derived DNA among 1,868 male pesticide applicators in an independent AHS study.
