Provided are processes for the prevention or treatment of viral infection in a subject. Some aspects provide administration of a sphingoid compound, optionally sphingosine, an active ingredient that activates generation of a sphingoid base, optionally of sphingosine; or an active agent that inhibits the degradation of a sphingoid base, optionally of sphingosine, to a subject such as a human. By increasing the local concentration of sphingosine in a subject or an area of a subject to which the composition is administered such as the nose or interior of the nose or portion thereof, the ability of viruses to infect the subject or cells thereof is reduced thereby treating of preventing infection by the virus.

The present invention provides an oncolytic virus comprising nucleotide sequence(s) encoding one or more immune checkpoint modulator(s). It also concerns a pharmaceutical composition comprising effective amount of said oncolytic virus and, eventually, a pharmaceutically acceptable vehicle and its use for treating proliferative diseases such as cancers.

The present invention is related to a dual promoter lentiviral vector and methods of use for the treatment of diseases and disorders, specifically lysosomal storage disorders.

A pharmaceutical composition containing (1) a therapeutically effective amount of hepatocyte-derived exosomes; and (2) a pharmaceutically-acceptable carrier is provided. Also provided herein is a method of inducing liver regeneration in a patient in need thereof, the method including administering to the patient a therapeutic amount of hepatocyte-derived exosomes, wherein liver regeneration is induced. Methods for up-regulating synthesis of synthesis of sphingosine-1-phosphate (S1P) in a hepatocyte by contacting the hepatocyte with at least one vesicle containing sphingosine kinase 2, and, optionally, ceramide and neutral ceramidase, are also disclosed.

It also concerns a pharmaceutical composition comprising effective amount of said oncolytic virus and, eventually, a pharmaceutically acceptable vehicle and its use for treating proliferative diseases such as cancers.

The present disclosure relates generally to the use of sphingolipid-metabolizing proteins to mitigate or minimize tissue damage resulting from injury or from disease, for example, pulmonary arterial hypertension (PAH) when the sphingolipid-metabolizing protein is delivered via expression from an Anc80 vector.

Proteins, compositions, and methods for treating Farber disease are provided.

Proteins, compositions, and methods for treating Farber disease are provided.

The present invention relates to methods of producing chondrocytes, improving the phenotype of a chondrocyte population, promoting chondrogenesis, maintaining a cell population in a differentiated state or increasing the number of cells of a population in a differentiated state, producing a population of differentiated cells, and treating certain diseases or disorders. Each of these methods involves treating a cell population with, and/or culturing a cell population in, a ceramidase
