In this work, the RLK10 peptide was obtained from the GKY10 peptide, by replacing the glutamine residue with an asparagine.

Vast evidence verified that BD elicits neuronal and cognitive impairments. Debilitated autophagic machinery is a key culprit in BD-induced neurotoxicity. Palonosetron is a potent selective serotonin 5-HT3 receptor antagonist whose impact on BD has not yet been scrutinized. Thus, the present study aimed at exposing the potentiality of palonosetron and its link with AKT/mTOR/AMPK/ULK1 pathway in the BD-rat model. Rats were divided into 4 groups; group 1 received saline and Vanilla Ensure® Plus, whereas groups 2, 3 and 4 received 20 % w/v ethanol in Vanilla Ensure® Plus (intragastric gavage) every 8 h for 4 days, concomitantly with palonosetron (0.1 mg/kg, twice daily; i.p.) in groups 3 and 4, and chloroquine (50 mg/kg/day; i.p.) in group 4. BD impaired memory, locomotor, and cognitive functions, with concomitant TNF-α and IL-1β elevation implicating neuroinflammation-driven cognitive decline. The former effect was, mechanistically, triggered by halting autophagy via augmenting hippocampal pAKT/tAKT, pmTOR/tmTOR and pULK1/tULK1 ratios, while reducing pAMPK/tAMPK, with resultant imbalance of the autophagic markers; Beclin-1, LC3-II/LC3-I, p62 and caspase-3. Aberrant upregulation of miRNA-155 was also detected and was markedly correlated to AKT/mTOR/AMPK and autophagy trajectories. Palonosetron treatment significantly alleviated all the aforementioned deviations. Histopathological analysis further corroborated palonosetron neuroprotective effect. Chloroquine, a classical autophagy inhibitor, blunted palonosetron-induced improvement.

The composition of these membranes varies significantly across different cell types, species, and disease states, influencing their mechanical properties and susceptibility to disruption. This variability presents an opportunity to selectively target pathological cells based on their unique lipid profiles, potentially allowing for the precise disruption of diseased cells while sparing healthy ones. Additionally, focused ultrasound (FUS) has emerged as a promising tool for modulating membrane integrity, with applications in targeted drug delivery and cancer therapy. However, the precise interactions between FUS waves and different lipid compositions remain insufficiently understood. This study systematically investigates the effects of varying ultrasound frequencies (5–50 MHz) and overpressures (5–50 bar) on the mechanical responses of four distinct lipid bilayers—POPC, POPE, POPG, and POPS—using molecular dynamics simulations. These lipids are commonly found in mammalian, bacterial, and cancerous cell membranes. Key structural parameters, including area per lipid, curvature, thickness, and lipid tail order, were analyzed to determine how different ultrasound conditions affect membrane integrity. The results reveal that lipid composition critically determines membrane vulnerability to mechanical perturbations. For instance, POPC membranes are more prone to deformation under certain ultrasound conditions, while POPG and POPS exhibit abrupt transitions to instability at extreme pressures and frequencies. These findings offer valuable insights into the selective tuning of ultrasound parameters for therapeutic applications and highlight the critical role of membrane composition in determining mechanical responses to ultrasound-induced stress.</div></div>","PeriodicalId":8174,"journal":{"name":"Archives of biochemistry and biophysics","volume":"771 ","pages":"Article 110523"},"PeriodicalIF":3.8,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the potential antimicrobial efficacy of ionic liquids, particularly against fungal pathogens. For this, a functionalized chiral ionic liquid (FCIL) with a naturally occurring (1<em>R</em>,2<em>S</em>,5<em>R</em>)-(−)-menthol moiety and a long alkyl chain was synthesized and characterized using spectral and thermal methods. The antifungal potential of this FCIL was evaluated by examining interactions with artificial fungal and mammalian membranes modeled as Langmuir monolayers. Thermodynamic analyses, complemented by adsorption and penetration experiments, Brewster angle microscopy, polarization modulation infrared reflection absorption spectroscopy, and molecular dynamics simulations, showed that FCIL incorporated into membranes and caused fungal membrane disintegration. This can be related to <em>π-π</em> interactions with ergosterol, a primary fungal membrane sterol, and favorable assimilation into membranes containing dioleoylphosphatidylcholine, an unsaturated phospholipid abundant in fungal cells. Conversely, interactions with mammalian membranes modeled using dipalmitoylphosphatidylcholine and cholesterol were thermodynamically unfavorable due to their tighter packing. These findings underline the FCIL's ability to selectively disrupt fungal membranes and suggest its potential use as a targeted antifungal agent with reduced mammalian cell toxicity. This research highlights the benefit of integrating experimental and computational methods to understand the molecular mechanics driving selective antifungal activity.</div></div>","PeriodicalId":8174,"journal":{"name":"Archives of biochemistry and biophysics","volume":"771 ","pages":"Article 110524"},"PeriodicalIF":3.8,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
