CD39, also known as ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1), is a cell surface ectonucleotidase with key roles in modulating inflammation and localized immune regulation. Researchers from the Baker Heart and Diabetes Institute and collaborators recently proposed leveraging mRNA technologies to provide sustained, localized CD39 expression without genomic integration.
Daewoong Pharmaceutical Co. Ltd. announced after South Korean market hours May 21 that it gained successive rights to Turn Biotechnologies Inc.’s mRNA-based cellular rejuvenation platform from Hanall Biopharma Co. Ltd.

Create Medicines Inc. closed a $122 million series B financing round to support its pipeline of therapies that use mRNAs delivered via liquid nanoparticles to express chimeric antigen receptors (CARs) in T cells, NK cells and myeloid cells inside the body of patients. The Cambridge, Mass.-based company estimates the capital will last through 2028, providing the opportunity for multiple clinical readouts of its various products.
A new mRNA and lipid nanoparticle (mRNA-LNP) platform could selectively reprogram in vivo cytotoxic effector T cells (Teff), the cells responsible for eliminating infected or tumor cells. To achieve this, scientists at the University of Pennsylvania conjugated LNPs with fractalkine, a molecule that binds to the CX3CR1 receptor, which is a marker of Teff cells. Using this strategy, the researchers delivered an mRNA encoding new proteins such as IL‑2 or human CD62 L‑selectin, opening the door to temporarily reprogramming these cells within the body, both in the blood and in lymphoid tissue, where they reside and become activated.

Researchers from the University of Naples Federico II (Italy) and collaborating institutions reportedd the design of a next-generation mRNA vaccine that leverages a phylogenetically informed consensus receptor binding domain heterotrimers representing the major variant lineages.
A week after catching Moderna Inc. and its investors off guard with a refuse-to-file letter, the U.S. FDA has reversed course on the company’s BLA submission seeking approval of seasonal influenza vaccine mRNA-1010, now agreeing to review the application and setting an assigned PDUFA date of Aug. 5, 2026.
BioWorld’s 2022 end-of-year highlights included a toast to the future – of universal vaccines. Even before SARS-CoV-2 vaccines were developed in record time and saved countless lives during the COVID-19 pandemic, vaccines were a rare bright spot in the fight against infectious diseases. Bacteria are becoming multidrug resistant far faster than new classes of antibiotics are being developed, viral spillover events and vector ranges are increasing, and climate change is helping bacteria and fungi alike breach human thermal protections against infections.
The cardiomyositis that is a rare adverse effect of mRNA-based COVID vaccines is due to immune cell activity as a result of increased levels of the chemokines CXCL10 and interferon-γ (IFN-γ). Blocking CXCL10 and IFN-γ could prevent muscle cell damage in cell culture, and cardiomyositis in animal models. The findings, reported in the Dec. 10, 2025, issue of Science Translational Medicine, suggest a way of mitigating the risk of cardiomyositis.
