Growth, Dissolution and Segregation of Genetically Encoded RNA Droplets by Ribozyme Catalysis

open access: yesAngewandte Chemie, EarlyView.
Ribozymes enable sequence‐encoded turnover of RNA droplet material, resulting in transiently active droplets that selectively segregate based on their genotype. This establishes a direct link between genetic information and droplet behavior, marking a step toward programmable, evolvable RNA‐based compartments with life‐like properties.

Confined B‐Cell Reconstruction and High T‐Cell Clonality Define Clinical Response to Cladribine Treatment

open access: yesAnnals of Neurology, EarlyView.
Cladribine tablets are approved for relapsing multiple sclerosis, mediating their clinical effect by moderately depleting lymphocytes. In a prospective, monocentric study including 22 patients completing 2 annual cycles of cladribine, B‐ and T‐cell receptor repertoires and relapse activity were assessed at baseline and after 24 months. T‐cell clonality

Biocatalytic Regioselective C‐Formylation of Resorcinol Derivatives

open access: yesAngewandte Chemie, EarlyView.
An acyltransferase from Chromobacterium sphagni (CsATase) was identified that catalyzes the regioselective formylation of resorcinol substrates. The formylation of substituted resorcinol derivatives yielded mono‐formylated products with up to 99% conversion and up to 74% isolated yield.

Chemical Proteomics Identifies Ketogenesis‐Mediated Cysteine Modifications Regulating Redox Function

open access: yesAngewandte Chemie, EarlyView.
Herein, we report ketone body induce cysteine modifications beyond lysine acylation, as revealed by integrating chemical proteomics with open‐search methods. Among the modifications, cysteine crotonation (Ccr) was chemically validated by endogenous peptide‐based co‐elution assays.

Programmable Antigen‐Specific Immunity via Self‐Adjuvanting Nanovaccines Co‐Delivering Immune Modulators

open access: yesAngewandte Chemie, EarlyView.
The self‐adjuvanting vaccine—comprising a covalent conjugate of antigen and adjuvant—was formulated into cationic lipid nanoparticles smaller than 100 nm to facilitate uptake by immune cells, with supplemental adjuvants incorporated to modulate immune responses.
