This study was performed to evaluate whether microRNAs (miRNAs) in circulating exosomes may serve as biomarkers of drug-induced liver, kidney, or muscle-injury. Quantitative PCR analyses were performed to measure the amounts of liver-specific miRNAs (miR-122, miR-192, and miR-155), kidney-specific miR-146a, or muscle-specific miR-206 in plasma and exosomes from mice treated with liver, kidney or muscle toxicants. The levels of liver-specific miRNAs in circulating plasma and exosomes were elevated in acetaminophen-induced liver injury and returned to basal levels by treatment with antioxidant -acetyl-cysteine. Circulating miR-146a and miR-206 were increased in cisplatin-induced nephrotoxicity and bupivacaine-induced myotoxicity, respectively. Taken together, these results indicate that circulating plasma and exosomal miRNAs can be used as potential biomarkers specific for drug-induced liver, kidney or muscle injury.

Introduction: Psoriasis is characterized by aberrant keratinocyte activity and immune cell infiltration, driven by immune-mediated pathways. MicroRNAs (miRNAs) play crucial roles in regulating these processes, offering insights into disease mechanisms and therapeutic targets.
Objectives: This study aimed to investigate changes in circulating miRNAs in psoriasis patients undergoing risankizumab therapy, an anti-IL-23 monoclonal antibody, to understand its impact on disease pathogenesis and treatment response.

Background: We have recently shown that, during acute severe COVID-19, SARS-CoV-2 spike protein (S) induces a cascade of events resulting in T cell apoptosis. Indeed, by neutralizing the protease activity of its receptor, ACE2, S induces an increase in circulating Angiotensin II (AngII), resulting in monocytic release of reactive oxygen species (ROS) and programmed T cell death.
Objective: Here, we tested whether SARS-CoV-2 mRNA vaccines, known to cause the circulation of the vaccine antigen, S-protein receptor binding domain (RBD), might trigger the same cascade.

Directly detecting biomarkers in liquid biopsy for diagnosis and personalized treatment plays a crucial role in managing cancer relapse and increasing survival rates. Typically, the standard analysis of circulating tumour DNA requires lengthy isolation, extraction, and amplification steps, leading to sample contamination, longer turnaround time and higher assay costs. Surface plasmon resonance is an emerging and promising technology for rapid and real-time dynamic biomarker monitoring in liquid biopsy.

Introduction: Multiple sclerosis (MS) is a chronic immune-mediated demyelinating disease of the CNS, whereby clinical disease activity is primarily monitored by magnetic resonance imaging (MRI).
Methods: Given the limitations associated with implementing and acquiring novel and emerging imaging biomarkers in routine clinical practice, the discovery of biofluid biomarkers may offer a more simple and cost-effective measure that would improve accessibility, standardization, and patient care. Extracellular vesicles (EVs) are nanoparticles secreted from cells under both homeostatic and pathological states, and have been recently investigated as biomarkers in MS.
