A comprehensive review of iPS cell line-based disease modelling of the polyglutamine spinocerebellar ataxias 2 and 3: a focus on the research outcomes.

Spinocerebellar ataxias (SCAs) are a rare autosomal dominant neurodegenerative disorder. To date, approximately 50 different subtypes of SCAs have been characterized. The prevalent types of SCAs are usually of PolyQ origin, wherein the disease pathology is a consequence of multiple glutamine residues being encoded onto the disease proteins, causing expansions. SCAs 2 and 3 are the most frequently diagnosed subtypes, wherein affected patients exhibit certain characteristic physiological manifestations, such as gait ataxia and dysarthria. Nevertheless, other clinical signs were exclusive to these subtypes. Recently, multiple molecular diagnostic methods have been developed to identify and characterize these subtypes. Despite these advancements, the molecular pathology of SCAs remains unknown. To further understand the mechanisms involved in neurodegenerative SCAs 2 and 3, patient-derived induced pluripotent stem cell (iPSC)-based modelling is a compelling avenue to pursue. We cover the present state of iPSC-based in-vitro illness modelling of SCA subtypes 2 and 3 below, along with a list of cell lines created, and the relevance of research outcomes to personalized autologous therapy.

Closing potential drivers of antimicrobial resistance: last-resort antimicrobials with the potential of being misused, the way forward - a short communication.

Antimicrobial resistance (AMR) is still a formidable global public health challenge, as microorganisms, including bacteria, viruses, fungi, and parasites, evolve resistance to commonly used drugs, particularly antibiotics. The preservation of last-resort antimicrobials is critical for treating multi-drug-resistant infections; however, their indiscriminate use can exacerbate AMR crisis. This short communication delves into the multifaceted challenges, innovative strategies, and promising future directions to combat AMR effectively. Factors such as inappropriate prescription practices and the dearth of novel antibiotics contribute to the emergence of AMR. By implementing antimicrobial stewardship programs and fostering public education, we can mitigate the misuse of these vital drugs. Future research endeavors should concentrate on the development of cutting-edge drugs and diagnostic technologies to address AMR with enhanced precision and efficiency. Additionally, robust surveillance systems are crucial for monitoring antibiotic use and resistance patterns, providing valuable insights to inform policy decisions. A concerted, collaborative effort from governments, policymakers, healthcare providers, researchers, and other stakeholders is indispensable for overcoming the global health crisis posed by AMR.
