  • Publication number: 20240197845
    Abstract: This disclosure describes, in one aspect, immunogens effective for treating and/or diagnosing tauopathy, and immunotherapeutic compositions and methods involving those immunogens. Generally, the immunogen includes an antigen presentation component and a microtubule-associated tau protein (MAPT) component linked to at least a portion of the antigen presentation component. This disclosure describes, in another aspect, a transgenic mouse. Generally, the transgenic mouse possesses brain cells that have a polynucleotide that encodes human microtubule-associated protein tau (MAPT). The polynucleotide further exhibits a deletion of at least a portion of endogenous mouse MAPT. The transgenic mouse also includes a forebrain neuron-specific deletion of a polynucleotide that encodes Myeloid Differentiation Primary Response Gene 88 (MyD88). In a further aspect, this disclosure describes a method of producing the transgenic mouse.

  • Publication number: 20210338793
    Abstract: The present invention relates to a system and method for controlling peptide display valency on virus-like particles (VLPs), especially including MS2 VLPs. In this method, large amounts of wild-type and low quantities of single-chain dimer coat proteins may be produced from a single RNA. Valency is controlled in immunogen (vaccine) production by providing a system that allows the production of large amounts of wild-type and low quantities of single-chain dimer coating proteins from a single RNA, allowing facile adjustment of display valency levels on VLPs, especially MS2 VLPS over a wide range, from few than one-on average- to as many as ninety per particle. This facilitates the production of immunogens and vaccines, including VLPs exhibiting low valency.

  • Patent number: 10821167
    Abstract: The present invention is directed to virus-like particles (VLPs) which are engineered to present epitopes from Staphylococcus aureus (SA), preferably autoinducing peptides (AIPs) which regulate quorum-sensing dependent virulence in this pathogen, or epitopes from SA toxins and leukocidins. These VLPs may be used to provide immunogenic compositions and efficacious vaccines. In a mouse model of SA dermonecrosis, vaccination with AIP-containing VLPs or SA toxin-containing VLPs induces protective immunity to limit the pathogenesis of SA infection and promote bacterial clearance.
