Although several key plasmid elements that balance mcr-1 persistence and bacterial growth are identified, the regulatory interactions between mcr-1 and host bacteria remain poorly understood. Using a genome-wide CRISPRi crRNA library, it is identified that DNA polymerase IV, dinB, is essential for controlling the fitness cost associated with mcr-1 in Escherichia coli. The absence of dinB operon enhances mcr-1-mediated colistin resistance but simultaneously compromises bacterial growth and competitiveness. Meanwhile, dinB deficiency mitigates inflammatory response in RAW267.4 cells and enhances bacterial colonization in murine tissues. Further investigation reveals that mcr-1 actively upregulates dinB expression, with the increased reactive oxygen species induced by mcr-1 being crucial for this activation.   These findings suggest that dinB modulates mcr expression and bacterial fitness via a negative feedback regulatory mechanism. Leveraging this regulatory relationship, a Toxin-Intein is engineered under the control of dinB promoter to selectively target and kill mcr-positive E. coli both in vitro and in vivo.

It is found that CaMKIIα+ neurons in the temporal association cortex (TeA) of mice are not essential for natural awakening from sleep. However, optogenetic activation of these neurons reliably induces wakefulness from non-rapid eye movement (NREM) sleep but not from rapid eye movement (REM) sleep. In vivo electrophysiological and calcium recordings further demonstrated that TeA neurons are monotonically tuned to sound intensity but not frequency. More importantly, it is found that the activity of CaMKIIα+ neurons in TeA can gate sound-evoked arousal from NREM sleep, which is further confirmed by optogenetic manipulations. Further investigation reveals that the baseline excitability of TeA CaMKIIα+ neurons and the delta oscillations in the electroencephalogram are particularly important in regulating the evoked activity of TeA neurons. Anatomical and functional screening of downstream targets of TeA reveals that excitatory projections from TeA glutamatergic neurons to glutamatergic neurons in the basolateral/lateral amygdala are critical for modulating sound-evoked arousal from NREM sleep.

It is demonstrated experimentally that the structural planarity of the dye molecules is crucial for the formation of chiral co-assemblies. Interestingly, the left-handed COS-templated co-assemblies can emit CPL with opposite handedness, which is controlled by the helicity degree of the co-assemblies.

It is recently reported that proautophagic autophagy/beclin-1 regulator 1 (AMBRA1) is a positive modulator of the NF-κB pathway that promotes intestinal inflammation. However, its effect on intestinal redox state and whether AMBRA1 is regulated by oxidative stress remain unknown. In this study, it is found that AMBRA1 functions as a pro-oxidative factor that increases oxidative stress in intestinal epithelial cells (IECs) in vitro and in vivo. Mechanistically, the N-terminal F1 domain is required for AMBRA1 to competitively interact with the N-terminal domain of NRF2, thereby antagonizing the interaction between deubiquitinating protein 3 (DUB3) and NRF2, suppressing DUB3-mediated NRF2 deubiquitination, and leading to NRF2 degradation. In response to H<sub>2</sub>O<sub>2</sub> stimulation, the interaction between AMBRA1 and ubiquitin-specific protease 7 (USP7) is enhanced, facilitating USP7 to deubiquitinate AMBRA1 at K83 and K86 and stabilize AMBRA1. Notably, the USP7 inhibitor, P5091, inhibits oxidative stress and colitis in vivo. Elevated AMBRA1 expression in inflamed colon tissues from ulcerative colitis patients is negatively correlated with decreased NRF2 protein levels.

Here, we introduce a transformative wearable corneal microneedle (MN) patch designed for efficient therapy of ocular injury and infection. The MN patch comprises water-soluble tips that encapsulate antibacterial nanoparticles (NPs), along with a transformative backing layer that contains epidermal growth factor (EGF). Upon insertion into the eye, the MN tips dissolve swiftly within the cornea stroma, resulting in the release of the antimicrobial NPs to efficiently eradicate bacteria. Meanwhile, the residual backing layer undergoes rapid in situ transformation upon contact with mildly acidic fluid from infected corneal edema, converting into a contact lens that conforms to the eye's surface, which facilitates sustained release of EGF on the ocular surface over 8 h to promote corneal healing. Benefiting from these features, the designed transformative corneal MN patch demonstrates superior efficacy in treating ocular injuries and infections in vivo, offering a promising therapeutic strategy to manage eye diseases.</p>","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e2414548"},"PeriodicalIF":14.3,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143062461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
