Article Abstract
is a spore-forming enteric pathogen causing life-threatening diarrhoea and colitis. Microbial disruption caused by antibiotics has been linked with susceptibility to, and transmission and relapse of, infection. Therefore, there is an urgent need for novel therapeutics that are effective in preventing growth, spore germination, and outgrowth. In recent years bacteriophage-derived endolysins and their derivatives show promise as a novel class of antibacterial agents. In this study, we recombinantly expressed and characterized a cell wall hydrolase (CWH) lysin from phage, phiMMP01. The full-length CWH displayed lytic activity against selected strains. However, removing the N-terminal cell wall binding domain, creating CWH, resulted in increased and/or an expanded lytic spectrum of activity. specificity was retained versus commensal clostridia and other bacterial species. As expected, the putative cell wall binding domain, CWH, was completely inactive. We also observe the effect of CWH on preventing spore outgrowth. Our results suggest that CWH has therapeutic potential as an antimicrobial agent against infection.

Diagnoses of prediabetes and metabolic syndromes, such as metabolic-associated steatotic liver disease (MASLD), are increasing at an alarming rate worldwide, often simultaneously. A significant consequence of these is high risk of cardiovascular disease, highlighting the need for cardiac-specific therapeutics for intervention during the prediabetic stage. Recent studies have demonstrated that chemogenetic activation of the cardiac parasympathetic system through hypothalamic oxytocin (OXT) neurons provides cardioprotective effects in heart disease models by targeting excitatory neurotransmission to brainstem cardiac vagal neurons.

Angiogenesis, the formation of new blood vessels from pre-existing vasculature, is a crucial process in both physiological and pathological contexts, including cancer. Phospholipases A (PLAs), enzymes found in snake venoms, have attracted attention due to their potential antiangiogenic properties. In this study, we explored the antiangiogenic effects of PLA isoforms isolated from Bothrops diporus venom using a combination of in vivo and ex vivo models.

The growing challenges posed by global warming and the demand for sustainable food and feed resources underscore the need for robust microbial platforms in bioprocessing. Thermotolerant yeasts have emerged as promising candidates due to their ability to thrive at elevated temperatures and other industrially relevant stresses. This review examines the industrial potential of thermotolerant yeasts in the context of climate change, emphasizing how their resilience can lead to more energy-efficient and cost-effective bioprocesses.
