However, the processes and pathways leading to the formation of cyanobacterial blooms are largely stochastic, and a targeted quantitative model incorporating multiple drivers is required. A series of fieldwork and analytical procedures were conducted on 11 lakes in Beijing-Tianjin-Hebei and neighboring regions. The objective of this research was to investigate the effects of location, climate, habitat, metabolism and biology on the abundance of cyanobacteria. The findings indicated that location factors exerted an indirect influence on cyanobacterial density, with a calculated effect size of −0.001. This observation is consistent with the documented prevalence of cyanobacterial bloom outbreaks, suggesting that cyanobacterial abundance is not directly associated with location. Furthermore, the water environment (0.35 indirect and −0.37 direct effects) and climatic conditions (−0.2 indirect and 0.16 direct effects) had significant direct and indirect effects on cyanobacterial cell densities. It was also determined that high nutrients and high temperatures remained the basis for promoting cyanobacterial blooms. It is noteworthy that the microbial community exerted a substantial inhibitory effect on the proliferation of the cyanobacterial community (1.13 direct inhibitory effect). It is hypothesized that the negative effect is derived from two primary sources: the competition for ecological niches by organisms exhibiting similarity, and the direct inhibitory effect of certain bacteria on the growth of cyanobacteria, a negative correlation between acidobacteriota, bacteroide and a variety of cyanobacteria was observed in our study. The effect of specific bacteria is found to be significantly negatively correlated with the prevalence of a wide range of cyanobacteria, which is consistent with the results of many extant studies. These extant studies indicate that the formation of cyanobacterial communities is primarily influenced by microorganisms in the environment. The results of this study will provide new and complementary evidence on the mechanisms of cyanobacterial bloom occurrence and development and the design of management strategies.</div></div>","PeriodicalId":34305,"journal":{"name":"Current Research in Microbial Sciences","volume":"8 ","pages":"Article 100400"},"PeriodicalIF":4.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By facilitating viral replication, it promotes the dysregulation of inflammatory pathways, leading to cytokine storm, and triggers DNA damage response (DDR), thus exacerbating disease progression. The 2-E channel, a viroporin, is a promising antiviral target. However, the lack of specific inhibitors and effective screening methods has hindered therapeutic exploitation of the 2-E channel. To address this gap, we report on a fluorescence-based screening assay that targets the 2-E channel activity, resulting in the identification of potential inhibitory molecules. After performing both electrophysiological studies and surface plasmon resonance (SPR) analyses, we identified the top-ranked candidate, TPN10518, as a pore-blocking inhibitor of the 2-E channel. TPN10518 binds to a hydrophobic pocket in the C-terminal vestibule of the 2-E channel, thereby inhibiting its activity. Functional evaluation showed that TPN10518 exhibits significant antiviral efficacy <em>in vitro</em>, while, at the same time, effectively protecting against 2-E channel-mediated host damage and suppressing cytokine storm caused by dysregulated homeostasis of inflammatory pathways <em>in vivo</em>. Therefore, our work introduces a screening method for targeting 2-E channels, establishes the 2-E channel as a viable therapeutic target against SARS-CoV-2, and identifies TPN10518 as a promising antiviral candidate.</div></div>","PeriodicalId":34305,"journal":{"name":"Current Research in Microbial Sciences","volume":"9 ","pages":"Article 100409"},"PeriodicalIF":4.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When cultured in media acidified with hydrochloric, lactic, or acetic acid, wild-type LcS showed significantly more growth than an LCPS-1-deficient mutant strain (<em>p</em> &lt; 0.01), indicating that LCPS-1 confers enhanced protection against proton (<em>H</em><sup>+</sup>) stress. Wild-type LcS also exhibited a significant 73–83 % reduction (<em>p</em> &lt; 0.01) in negative surface potential compared to that of the mutant. Additionally, wild-type LcS showed significantly more growth than the mutant (<em>p</em> &lt; 0.01) in the presence of cupric oxide, which releases bactericidal Cu<sup>2+</sup> ions. In contrast, wild-type LcS was slightly more susceptible than the mutant to lethal concentrations of hydroxide ions. These findings suggest that LCPS-1 modulates the surface electric potential of LcS cells, thereby influencing the interaction strength between the cell walls and environmental ions, ultimately altering the tolerance of the cells to ionic stress factors. These findings provide crucial insights into the role of CWPSs in modulating the surface electric potential of microorganisms, which affects microbial interactions with environmental ions. This enhanced understanding of CWPS function enables the development of more resilient probiotic strains, potentially improving their efficacy in various industrial and therapeutic applications.</div></div>","PeriodicalId":34305,"journal":{"name":"Current Research in Microbial Sciences","volume":"9 ","pages":"Article 100430"},"PeriodicalIF":4.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144534316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
