Provided are a canine parvovirus (CPV) nanobody CPV-VHH-E3 and application thereof, belonging to the technical field of immunology. The nanobody CPV-VHH-E3 includes heavy chain variable region with amino acid sequence as shown in SEQ ID NO: 1, and a nucleotide sequence of a gene encoding the nanobody CPV-VHH-E3 is shown in SEQ ID NO: 2. The present application constructs a nanobody immune library for CPV by phage-display technology, and obtains specific anti-CPV nanobody CPV-VHH-E3 by screening, which is verified to specifically bind CPV through experiments, and is applicable to develop a nanobody preparation for clinical diagnosis and treatment of CPV, providing a certain theoretical support for the application of nanobodies in the field of veterinary biological products.

The disclosure relates, in some aspects, to compositions and methods for treatment of diseases associated with aberrant lysosomal function, for example Parkinson's disease (PD) and Gaucher disease. In some embodiments, the disclosure provides expression constructs comprising a transgene encoding beta-Glucocerebrosidase (GBA) or a portion thereof alone or in combination with one or more PD-associated genes. In some embodiments, the disclosure provides methods of Parkinson's disease by administering such expression constructs to a subject in need thereof.

The present invention relates to a method of quantifying the amount of Mock Virus Particles (MVP) removed from a solution as a result of processing that solution through a purification technique. This method involves the steps of adding MVP to a solution, processing the solution through a purification technique, quantifying the amount of MVP removed from the solution. The present invention also relates to a kit that can be used in conjunction with the method. This kit will comprise at least one stock solution of MVP and at least one quantification solution.

The present disclosure provides an isolated recombinant oncolytic adenovirus, a pharmaceutical composition, and uses thereof for drugs for treatment of tumors and/or cancers. The recombinant oncolytic adenovirus is a selectively replicating oncolytic adenovirus, and the genome of the recombinant oncolytic adenovirus is integrated with a coding sequence of exogenous shRNA capable of inhibiting PDL1 expression in tumor cells. The replication capability of the virus in normal primary cells is much lower than the replication capability of the virus in tumor cells. Moreover, the expressed shPDL1 can significantly reduce the level of PDL1 protein highly expressed in tumor cells. Thus, the oncolytic killing effect of the oncolytic virus and the anti-tumor immunostimulatory effect of immune cells produce a synergistic effect.
