The invention relates to a composition comprising at least one first aminopeptidase and at least one second aminopeptidase, the first aminopeptidase representing up to 40% by weight relative to the total weight of the composition.

Provided are compositions and methods for prophylaxis and/or therapy of ErbB2-positive cancer. The compositions include pharmaceutical preparations that contain isolated or recombinant or modified peptidase D (PEPD) proteins. The methods include prophylaxis and/or therapy of ErbB2-positive cancer by administering a PEPD to an individual who has or is at risk for developing ErbB2-positive cancer.

The present disclosure provides various insights relating to treatment of viral infection with soluble ACE2 variants, specifically including soluble human ACE2 (hACE2) variants. For example, the present disclosure teaches that decoy activity, which may intercept virus-receptor interactions, and ACE2 enzymatic activity can provide separate contributions to therapeutic efficacy; among other things, the present disclosure provides particular therapeutic regimens (e.g., relating to treatment of particular patient populations and/or to dosing regimens, combination therapies, etc.) for certain soluble ACE2 variants. Still further, the present disclosure provides certain particular ACE2 variants and methods of making and/or using them, including in accordance with particular therapeutic regimens.

Disclosed herein are methods for treating a primate in need of tripeptidyl peptidase 1 (TPP1), comprising (a) providing a recombinant adeno-associated virus (AAV) vector comprising a nucleic acid encoding TPP1; and (b) administering an amount of the recombinant AAV vector to the central nervous system (CNS) of the primate, wherein the TPP1 is expressed in the primate.

Provided is a method for preventing or treating a metabolic disorder, including administering to a subject a therapeutically effective amount of TRABID protein or a functionally related variant thereof, or a nucleic acid encoding TRABID protein or a functionally related variant thereof. Also provided is a method for reducing fat accumulation through TRABID-induced deubiquitination to promote autophagy activity and lipid metabolism.

Disclosed herein are exosomes, compositions, and methods for the treatment of subjects infected with, or at risk for infection with a coronavirus, such as SARS-CoV-2, HCoV-NL63, or SARS-CoV. The disclosed exosomes comprise ACE2 protein and typically display ACE2 protein on the exosome surface. In some embodiment, the exosomes optionally are loaded with one or more additional therapeutic agents for treating an infection by a coronavirus, such as remdesivir. In some embodiments, compositions comprising the exosomes are administered to a subject in need thereof, e.g., to a subject diagnosed with, or suspected of having a SARS-CoV-2 infection, an HCoV-NL63 infection, or a SARS-CoV infection. In some embodiments, administration is via inhalation. In some embodiments, administration is via injection.

Provided herein are methods for the treatment of lysosomal storage disease comprising administration of genes encoding for a lysosomal enzyme and a pharmaceutical agent. Combining gene therapy with pharmaceutical compositions by co-administration not only further enhances the effects of each individual therapy, but also provides a multi-faceted approach to treatment because of the varying mechanism of action of each individual composition.

This disclosure is directed, at least in part, to GPCR modulators in combination therapies useful for the treatment of conditions or disorders involving the gut-brain axis. In some embodiments, these modulators are gut-restricted compounds. In some embodiments, these modulators are GPCR agonists, antagonists, inverse agonists, neutral antagonists, positive allosteric modulators, or negative allosteric modulators. In some embodiments, the condition or disorder is a metabolic disorder, such as diabetes or obesity, or a nutritional disorder such as short bowel syndrome.

This disclosure is directed to inhibitory oligonucleotides, inhibitory peptides, compositions and methods for preventing or treating Coronavirus disease 2019 (COVID-19). In one aspect, the disclosure is directed to compositions that comprise inhibitory oligonucleotides against one or more SARS-CoV-2 virus genes. In another aspect, the disclosure is directed to compositions that comprise inhibitory peptides that inhibit SARS-COV-2 entry into cells. Another aspect of the disclosure is directed to gene therapy methods for treating COVID-19, and vectors for carrying out the same. Finally, the disclosure provides nutritional supplements to support human immunity and prevent or inhibit viral infections.
