Abstract: A bacteriophage T4-based, multivalent/multicomponent, needle and adjuvant-free, mucosal vaccine by engineering spike trimers on capsid exterior and nucleocapsid protein in the interior is disclosed herein. Intranasal administration of this T4-COVID vaccine induces higher virus neutralization antibody titers against multiple variants, balanced Th1/Th2 antibody and cytokine responses, stronger CD4+ and CD8+ T cell immunity, and higher secretory IgA titers in sera and bronchoalveolar lavage with no effect on the gut microbiota, compared to vaccination of mice intramuscularly. The vaccine is stable at ambient temperature, induce apparent sterilizing immunity, and provide complete protection against original SARS-CoV-2 strain and its Delta variant with minimal lung histopathology. This mucosal vaccine is an excellent candidate for boosting immunity of immunized and/or as a second-generation vaccine for the unimmunized population. This needle-free platform could be used to develop effective vaccines against many other respiratory infectious pathogens including Flu and any future emerging epidemic and pandemic pathogens.

Abstract: Embodiments of the invention provide systems, methods, and kits for CRISPR-based editing of DNA targets by a CRISPR-associated (Cas) enzyme. The systems include a bacterial host cell adapted to produce an engineered bacteriophage comprising a Cas protein and guide RNA that do not naturally occur together, i.e. they are engineered to occur together, as well as a DNA repair template comprising a donor DNA having a desired mutation. The guide RNA comprises a trans-activating crRNA and a guide sequence complementary to a target protospacer in a bacteriophage genome. A wild-type bacteriophage or a glucosylhydroxymethyl cytosine (ghmC)-unmodified mutant bacteriophage may be delivered into a disclosed bacterial host cell to create recombinants of bacteriophage having the desired mutation provided by the donor DNA.

Abstract: Provided herein are HIV vaccines that encompasses recombinant trimers that mimic native HIV-1 envelope trimers. Also provided are methods of administering to a subject in need thereof an HIV vaccine provided herein to elicit antibodies against a recombinant trimer in the subject. A recombinant trimer is formed by a recombinant protein comprising a recombinant HIV-1 gp140 fused to a tag through a linker at C-terminus of the recombinant HIV-1 gp140, wherein the linker is sufficiently long so that the tag is accessible for binding by a binding molecule bound on a solid matrix during purification of the recombinant trimer.

Abstract: An approach of producing recombinant trimers that mimic native HIV-1 envelope trimers is developed. A recombinant protein forming the recombinant trimers encompasses a recombinant HIV-1 gp140 fused to a tag through a linker at C-terminus of the recombinant HIV-1 gp140. The linker is sufficiently long so that the tag is accessible for binding by a binding molecule bound on a solid matrix. After expressed in a cell, the recombinant protein is secreted into the culture medium and assembles into recombinant trimers therein. The recombinant trimers may be directly purified from the culture medium. Cleaved and uncleaved trimers from different clade viruses are produced.

Abstract: Complex viruses are assembled from simple protein subunits by sequential and irreversible assembly. During genome packaging in bacteriophages, a powerful molecular motor assembles at the special portal vertex of an empty prohead to initiate packaging. An aspect of the invention relates to the phage T4 packaging machine being highly promiscuous, translocating DNA into finished phage heads as well as into proheads. Single motors can force exogenous DNA into phage heads at the same rate as into proheads and phage heads undergo repeated initiations, packaging multiple DNA molecules into the same head. This shows that the phage DNA packaging machine has unusual conformational plasticity, powering DNA into an apparently passive capsid receptacle, including the highly stable virus shell, until it is full. These features allow for the design of a novel class of nanocapsid delivery vehicles.
