Abstract: Provided herein, in some aspects, are compositions of nucleic acids comprising an initial transcribed sequence and unique nucleic acid designs for high-yield and cost-effective production of ribonucleic acids.

Abstract: In the various aspects and embodiments, this disclosure provides messenger RNA (mRNA) constructs for therapeutic delivery, as well as methods for making such mRNA constructs and pharmaceutical compositions comprising the same (including mRNA vaccine compositions). In still other aspects, the invention provides methods for treating patients by expression of therapeutic proteins, including for preventing or reducing probability of infection by, or illness involving, a virus. Exemplary viruses include coronaviruses (such as SARS-CoV-2 and variants therefore) and influenza viruses, among others.

Abstract: The current subject matter includes methods, systems, articles, and techniques to deliver material to anucleate cells, such as red blood cells. Using a rapid deformation based microfluidic system, loading of red blood cells with macromolecules of different sizes has been shown. Although delivery to some mammalian cells, such as cancer cell lines and fibroblasts had been previously demonstrated using this technique, those designs were incompatible with RBCs that have dramatically different physical properties. Through the use of smaller constriction sizes, high speeds and different buffers successful delivery to red blood cells can be achieved. By enabling robust delivery to red blood cells in a simple, scalable manner, the current subject matter can be implemented in a diversity of applications that deliver material to study red blood cell diseases and/or use red blood cells as a therapeutic platform. Related apparatus, systems, techniques, and articles are also described.

Abstract: Provided herein, are compositions based on retroviruses (e.g., lentiviruses) comprising one or more nucleic acid molecules encoding retroviral Pol polyprotein components and a nucleic acid molecule comprising one or more transgene sequences flanked by long terminal repeat sequences, for delivery of the one or more transgenes to a target cell ex vivo or in vivo. The compositions are useful for delivering to a target cell (e.g., hematopoietic stem cells (HSCs), liver cells, ocular cells, muscle cells, epithelial cells, T cells, etc.) and/or stably expressing any transgene (e.g., beta-globin, Factor VIII, RP GTPase regulator (RPGR), dystrophin, cystic fibrosis transmembrane conductance regulator (CFTR), a chimeric antigen receptor, etc.) with a biological effect to treat and/or ameliorate the symptoms associated with any disorder related to gene expression (e.g., sickle cell disease, beta-thalassemia, haemophilia B, retinitis pigmentosa, Duchenne muscular dystrophy, cystic fibrosis, cancer, etc.).
