The disclosure is directed in part to variant capsid polypeptides that can be used to deliver payloads.

Provided herein are chimeric minigenes, where the alternative splicing of the minigene determines whether an encoded gene is expressed. In particular, the minigenes are alternatively spliced in response to splicing modulator dmgs, such that the encoded gene is only expressed in the present of the splicing modulator dmg. The encoded gene may encode an inhibitory RNA, a CRISPR-Cas9 protein, a transactivator, or a therapeutic protein.

The present invention relates to a novel equine parvovirus associated with respiratory distress and recurrent laryngeal neuropathy in equine, to nucleic acid fragments and proteins of the virus and to vaccines based upon the virus, proteins and nucleic acid fragments. The invention also relates to a diagnostic test for the detection of the vims or antibodies against the virus.

The disclosure in some aspects relates to recombinant adeno-associated viruses having distinct tissue targeting capabilities. In some aspects, the disclosure relates to gene transfer methods using the recombinant adeno-associated viruses. In some aspects, the disclosure relates to isolated AAV capsid proteins and isolated nucleic acids encoding the same.

“MAAP” is a naturally-occurring, newly-discovered about 13 KDa adeno-associated vims protein. It is not homologous to known proteins. When AAV producer cells are cultured for more than 24 hours, we found that inactivating translation of the full-length MAAP improves the productivity of the transfected producer cells. The resulting AAV viruses are also of better quality and more stable. Our findings thus provide a way to improve the industrial manufacture of recombinant adeno-associated virus gene therapy vectors.
