The present invention relates to novel antiviral compounds which are covalently attached to solid, macro surfaces. In another embodiment, the invention relates to novel antiviral compositions including a polymeric material and, embedded therein, an antiviral compound. In other embodiments, the invention relates to making a surface antiviral and making a polymeric material antiviral.

Engineered trimeric CD70 proteins for use in ex vivo T cell manufacturing are described. Use of the proteins during manufacturing creates expanded T cell populations with enhanced properties such as earlier proliferation in culture; selective expansion of nave and memory T cell subsets; longer persistence in vivo following administration to a subject; and improved therapeutic effect. Use of the proteins as therapeutics provide anti-cancer and anti-viral effects. The proteins can also be used as agonistic cell culture reagents in in vitro uses.

New insecticidal proteins, nucleotides, peptides, their expression in plants, methods of producing the peptides, new processes, production techniques, new peptides, new formulations, and new organisms, a process which increases the insecticidal peptide production yield from yeast expression systems. The present disclosure is also related and discloses toxins called AVPs, which are modified from the Av3 toxin derived from sea anemone; here we describe the genes encoding the new polypeptide, as well various formulations and combinations; of both genes and peptides, useful for the control of insects.

The present disclosure provides, inter alia, genetically encoded recombinant peptide biosensors comprising analyte-binding framework portions and signaling portions, wherein the signaling portions are present within the framework portions at sites or amino acid positions that undergo a conformational change upon interaction of the framework portion with an analyte.
