Antigen presentation within solid tumours presents a significant clinical challenge for systemic immune activation. Although radiotherapy or chemotherapy can generate tumour antigens by destroying tumour cells, the insufficient number and impaired function of dendritic cells within solid tumours compromises effective antigen presentation. Here we present plant-derived nanoparticles coated with nanohydroxyapatite that promote dendritic cell activation and amplify the production of dendritic-ce... Read more ›
Engineering the genetic code—by reassigning multiple of the 64 natural codons—enables making organisms resistant to all viruses, preventing genetic information exchange, and allowing the biosynthesis of genetically encoded unnatural polymers. However, synonymous codon replacement—recoding—is frequently lethal, and how recoding impacts fitness remains poorly explored. Here, we explore these effects using genome synthesis, directed evolution, and genome-transcriptome-translatome-proteome co-pro... Read more ›
Precise, reversible control of gene expression from self‑amplifying RNA (saRNA) remains difficult, limiting the therapeutic flexibility of this otherwise potent platform. Although alphavirus‑derived saRNAs encode non‑structural proteins that drive RNA replication and offer an intrinsic regulatory point, no existing approach has enabled direct, drug‑dependent control of this machinery for high‑fidelity modulation of expression. Here we engineer saRNA constructs whose replication is activated b... Read more ›
Vitiligo is a multifaceted autoimmune skin disease characterized by the loss of epidermal melanocytes, yet its molecular basis remains poorly understood. To address the need for a specialized systems biology interface, we present VIRdb v3.0, an integrative database combining curated transcriptomics-based datasets with differentially expressed genes, a protein–protein interaction network highlighting regulatory hubs, and an enriched library of natural compounds and FDA-approved drugs targeting...
