The intestinal mucosal barrier can be reinforced via the oral administration of commensal bacteria coated with poly(ethylene glycol) to facilitate their penetration into mucus.
An automated perfusable microfluidic bioreactor can generate clinical doses of viable CAR T cells that are functionally comparable to cells produced in standard open-culture systems.
Cytidine deaminases with high editing efficiencies, diverse editing windows and increased ratios of on-target to off-target effects can be discovered via structure-based generative machine learning.
Subcutaneously injected biomaterial scaffolds mimicking key features of physiological T-cell activation enhance the antitumour activity of intravenously pre-administered CAR-T cells.
The functions of non-coding regulatory elements can be systematically studied genome-wide at high throughput in human cells via their Cas9-mediated deletion through libraries of paired single-guide RNAs targeting both ends of each element.
Multilingual articulatory representations in the speech-motor cortex of a participant with vocal-tract and limb paralysis enabled the development of a bilingual speech neuroprosthesis.
Extracellular vesicles decorated with an antibody-binding moiety specific for the fragment crystallizable domain can be used as a modular delivery system for targeted cancer therapy.
A spatial multi-omics method with high decoding capacity and reduced sequencing and imaging costs enhances the high-throughput detection of gene mutations, allele-specific expression and RNA modifications in tissue samples.
Bioluminescent sources can be detected with magnetic resonance imaging by leveraging the light-mediated activation of vascular cells expressing a photosensitive bacterial enzyme that causes alterations in local haemodynamic contrast.
Pseudotyping messenger RNA-packaging virus-like particles with a glycoprotein recognizing a surface protein on dendritic cells led to higher humoral and adaptive immune responses in mice.
Transthoracic ultrasound localization microscopy enables super-resolution imaging of myocardial microvasculature and haemodynamics in patients with impaired myocardial function using data acquired within a breath hold.
Durable and robust lymph-node expansion is associated with the efficacy of therapeutic vaccination, as shown in mice immunized via a biomaterial-based vaccine.
Intramyocardial injection of synthetic mRNA coding for the embryonic T-box transcription factor 18 gene generates rate-adaptive cardiac pacing and limits innate and inflammatory immune responses, as shown in rodents and pigs.
The removal of terminal sialic acid residues on glycans at the T-cell–tumour-cell interface via a sialidase fused to a bispecific T-cell engager enhances the susceptibility of solid cancers to T-cell-mediated cytolysis.
The hydrophobicity, electrostatic charge and secondary conformation of helical polypeptides can be optimized to stimulate antitumour innate immune responses via endoplasmic reticulum stress in antigen-presenting cells.
The densities of blood vessels and of tumour-associated macrophages are key predictive features of the degree of accumulation of polymeric and liposomal nanomedicines, as shown for specimens of mouse and human tumours.
The esterification of butyrate to serine makes for an odourless and tasteless oral prodrug that ameliorated disease severity and reduced inflammatory responses in mouse models of rheumatoid arthritis and multiple sclerosis.
Antigen-specific immunosuppression can be enhanced by genetically modifying mesenchymal stromal cells with chimaeric antigen receptors, as shown for the treatment of graft-versus-host disease in mice.
Intratumourally administered bacteria coated with manganese dioxide modulate the immunosuppressive tumour microenvironment and potently activate antitumour immune responses, as shown in multiple solid tumours in small animals.
Blocking the mechanical sensor PIEZO1 in cytotoxic T lymphocytes strengthens their traction forces and augments their cytotoxicity against tumour cells.
