A gene therapy based on an enhanced lipid nanoparticle (LNP) loaded with vascular endothelial growth factor (VEGF) mRNA could be developed for the treatment of preeclampsia, according to a study in mice in which it alleviated maternal hypertension until the end of gestation and improved fetal health. Preeclampsia is a disease that affects 3% to 5% of pregnant women, who suffer from hypertension and proteinuria, elevated levels of protein in the urine, during pregnancy.
Clostridioides difficile is traditionally isolated from healthcare facilities' inpatients, but it is increasingly being identified in people who have not recently been hospitalized and is more and more found in community settings. Investigators from Perelman School of Medicine at University of Pennsylvania developed an mRNA-LNP vaccine with promising results in preventing and controlling C. difficile infection.

Multiple sulfatase deficiency (MSD) is a rare lysosomal storage disorder caused by pathogenic variants in the sulfatase modifying factor 1 gene (SUMF1). Researchers from the University of Pennsylvania described the efficacy of hematopoietic stem cell transplantation (HSCT) with ex vivo SUMF1 lentiviral gene therapy (SUMF1-GT) in a mouse model of MSD.
A team of scientists from the Perelman School of Medicine at the University of Pennsylvania and Aum Biotech LLC have described the development of a novel cancer immunotherapy designed to target FOXP3-positive T regulatory cells (Tregs) with a next generation of antisense oligonucleotides (ASOs), termed FOXP3 Aumsilence ASO. In contrast to previous ASOs, FOXP3 Aumsilence ASOs do not require delivery agents, and are capable of highly specific RNA silencing of previously undruggable targets.
The gastrointestinal tract could be key to developing new drugs to combat resistant bacteria. Computational analysis of the human microbiome has revealed a new class of peptides with antimicrobial potential that, once synthesized, inhibited the growth of several microorganisms in vitro and in vivo.
To be successful, CAR T-cells need a balance between being effective and overkill. Researchers from the University of Pennsylvania and Vittoria Biotherapeutics Inc. have eliminated the CD5 signaling pathway of their CAR Ts to prevent the immunosuppressive brake effect. In return, this improved their proliferation and antitumor activity in T cell lymphomas.
Researchers from the University of Pennsylvania have successfully inhibited vasohibin enzymes (VASH) with SVC-01 and SVC-02 in the ZSF1 obese rat model of heart failure with preserved ejection fraction (HFpEF).
A preclinical trial in mice and ferrets of an experimental mRNA vaccine against the H5 highly pathogenic avian influenza (HPAI) virus generated neutralizing antibodies and prevented severe illness and mortality of the animals.
