The endosomal escape of lipid nanoparticles (LNPs) is crucial for efficient mRNA-based therapeutics. Here, we present a cationic polymeric micelle (cPM) as a safe and potent co-delivery system with enhanced endosomal escape capabilities. Methods: We synthesized a cationic and ampholytic di-block copolymer, poly (poly (ethylene glycol)4-5 methacrylatea-co-hexyl methacrylateb)X-b-poly(butyl methacrylatec-co-dimethylaminoethyl methacrylated-co-propyl acrylatee)Y (p(PEG4-5MAa-co-HMAb)X-b-p(BMAc-co-DMAEMAd-co-PAAe)Y), via reversible addition–fragmentation chain transfer polymerization.

新合生物期待通过本项临床试验，进一步观察并确认基于肿瘤新抗原疫苗在治疗中晚期胃癌、食管癌的治疗效果，帮助受试者延长病情稳定性及生存期、提升生活质量。

Target selection of the personalized cancer neoantigen vaccine, which is highly dependent on computational prediction algorithms, is crucial for its clinical efficacy. Due to the limited number of experimentally validated immunogenic neoepitopes as well as the complexity of neoantigens in eliciting T cell response, the accuracy of neoepitope immunogenicity prediction methods requires persistent efforts for improvement. We present a deep learning framework for neoepitope immunogenicity prediction – SIGANEO by integrating GAN-like network with similarity network to address issues of missing values and limited data concerning neoantigen prediction.

Gasdermins, a family of five pore-forming proteins (GSDMA–GSDME) in humans expressed predominantly in the skin, mucosa and immune sentinel cells, are key executioners of inflammatory cell death (pyroptosis), which recruits immune cells to infection sites and promotes protective immunity. Pore formation is triggered by gasdermin cleavage. Although the proteases that activate GSDMB, C, D and E have been identified, how GSDMA—the dominant gasdermin in the skin—is activated, remains unknown. Streptococcus pyogenes, also known as group A Streptococcus (GAS), is a major skin pathogen that causes substantial morbidity and mortality worldwide.
