Herein, a multifunctional liposomal system (CR-Lip) for encapsulating celastrol (CEL) was utilized to remodel obesity-related ITME and improve cancer immunotherapy, wherein Ginsenoside Rg3 (Rg3) was detected interspersed in the phospholipid bilayer and its glycosyl exposed on the surface of the liposome. CR-Lip had a relatively uniform size (116.5 nm), facilitating favorable tumor tissue accumulation through the interaction between Rg3 and glucose transporter 1 overexpressed in obese tumor cells. Upon reaching the tumor region, CR-Lip was found to induce the immunogenic cell death (ICD) of HFD tumor cells. Notably, the level of PHD3 in HFD tumor cells was effectively boosted by CR-Lip to effectively block metabolic reprogramming and increase the availability of major free fatty acids fuel sources. <em>In vivo</em>, experiments studies revealed that the easy-obtained nano platform stimulated enhanced the production of various cytokines in tumor tissues, DC maturation, CD8<sup>+</sup> T-cell infiltration, and synergistic anticancer therapeutic potency with aPD-1 (tumor inhibition rate = 82.1%) towards obesity-related melanoma.

These neurobehavioral comorbidities may have greater impacts on the quality of life of people with epilepsy than the seizures themselves and can profoundly interfere with the treatment compliance. While repeated seizures often lead to behavioral comorbidities, certain types of comorbid conditions may potentially increase the risk for epileptic seizures, indicative of some common mechanisms that might underlie these two conditions. As such, emerging evidence supports that inflammation within the brain might represent a key component of such a shared mechanism, given that neuroinflammation can be induced by seizures and various behavioral stressors, and in turn may exacerbate both conditions. Among inflammatory pathways that arise after prolonged seizures, PGE<sub>2</sub> signaling <em>via</em> the EP2 receptor promotes cytokine induction, blood–brain barrier disruption, reactive gliosis, neuronal death, and eventually, contributes to behavioral dysfunctions. Pharmacological inhibition of EP2 by small-molecule drug-like antagonists affords broad therapeutic benefits including anti-inflammatory and neuroprotective effects in several rodent seizure models, leading to long-lasting alleviation of neurobehavioral comorbidities, particularly cognitive impairments. Targeting this key inflammatory prostaglandin receptor might provide an adjunctive strategy, along with the current anti-seizure medications, to mitigate cognitive dysfunctions associated with seizure disorders.</div></div>","PeriodicalId":6906,"journal":{"name":"Acta Pharmaceutica Sinica.

By leveraging the perfluorocarbon sidechain, the nanosystem exhibits efficient internalization by TNBC cells and effectively escapes from lysosomal entrapment.

Moreover, oxygen derived from ozone decomposition enhances the efficacy of radiotherapy by alleviating tumor hypoxia. Notably, the combination of irradiation with ozone-loaded cisplatin prodrug nano system synergistically prompts antitumor efficacy and reduces cellular/systemic toxicity <em>in vitro</em> and <em>in vivo</em>. Furthermore, the combo regimen remodels the tumor microenvironment into an immune-favored state by triggering immunogenic cell death and relieving hypoxia, which provides a promising foundation for a combination regimen of immunotherapy.
