Previous studies have indicated that excessive consumption of PE can disrupt the cell membrane, leading to cell death. This implies the presence of a regulatory mechanism for EptA catalysis to maintain a balance between antimicrobial resistance and bacterial growth. Through microsecond-scale all-atom molecular dynamics simulations, we demonstrate that membrane lipid homeostasis modulates the conformational transition and catalytic activation of EptA. The conformation of EptA oscillates between closed and open states, ensuring the precise spatiotemporal sequence of substrates binding. Interestingly, the conformation of EptA is significantly influenced by its surrounding lipid microenvironment, particularly the PE proportion in the membrane. PE-rich membrane conditions initiate and stabilize the open conformation of EptA through both orthosteric and allosteric effects. Importantly, the reaction mediated by EptA gradually depletes PE in the membrane, ultimately hindering its conformational transition and catalytic activation. These findings collectively establish a self-promoted model, illustrating the regulatory mechanism of EptA during the development of antibiotic resistance.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"24 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142690564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, data-driven methods require exhaustive data curation under random SOH and state of charge (SOC) retirement conditions. Here, we show that the generative learning-assisted SOH estimation is promising in alleviating data scarcity and heterogeneity challenges, validated through a pulse injection dataset of 2700 retired lithium-ion battery samples, covering 3 cathode material types, 3 physical formats, 4 capacity designs, and 4 historical usages with 10 SOC levels. Using generated data, a regressor realizes accurate SOH estimations, with mean absolute percentage errors below 6% under unseen SOC. We predict that assuming uniform deployment of the proposed technique, this would save 4.9 billion USD in electricity costs and 35.8 billion kg CO2 emissions by mitigating data curation costs for a 2030 worldwide battery retirement scenario.

Through experiments with cells, female mice, female hamsters, and human lung organoids, we demonstrate that lysoTRAP effectively clears SARS-CoV-2. Importantly, unlike therapeutic agents targeting SARS-CoV-2 spike protein, lysoTRAP remains effective against nine pseudotyped variants and the authentic Omicron variant, demonstrating its resistance to SARS-CoV-2 mutations.

Rag-GTPases are known to signal amino acid availability to cellular pathways that regulate nutrient distribution such as the mechanistic target of rapamycin complex 1 (mTORC1) pathway and the transcription factors TFEB and TFE3. However, the contribution of these factors to humoral immunity remains undefined. Here, we show that B cell-intrinsic Rag-GTPases are critical for the development and activation of B cells. RagA/RagB deficient B cells fail to form GCs, produce antibodies, and to generate plasmablasts during both T-dependent (TD) and T-independent (TI) humoral immune responses. Deletion of RagA/RagB in GC B cells leads to abnormal dark zone (DZ) to light zone (LZ) ratio and reduced affinity maturation. Mechanistically, the Rag-GTPase complex constrains TFEB/TFE3 activity to prevent mitophagy dysregulation and maintain mitochondrial fitness in B cells, which are independent of canonical mTORC1 activation. TFEB/TFE3 deletion restores B cell development, GC formation in Peyer’s patches and TI humoral immunity, but not TD humoral immunity in the absence of Rag-GTPases. Collectively, our data establish the Rag GTPase-TFEB/TFE3 pathway as a likely mTORC1 independent mechanism to coordinating nutrient sensing and mitochondrial metabolism in B cells.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"7 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142690589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
