Gene therapy vectors can include a cytomegalovirus vector encoding one or more therapeutic donor genes. These vectors can be used in exemplary gene therapy methods for maintaining or improving one or more aspects of a recipient's physiological wellness and/or longevity. The recombinant viral vector can be administered or received intranasally or as an injectable therapeutic (singly or as a serial set of administrations) to beneficially cause one or more of the following salubrious effects in the patient: increased longevity, inhibited muscle degeneration, increases mitochondrial health, prevention of age-related hair loss, and/or increased blood glucose tolerance.

The present disclosure provides, among other things, methods for using presenilin based gene therapy to treat neurodegenerative dementia including, but not limited to Alzheimers disease, frontotemporal dementia, frontotemporal lobar degeneration, Picks disease, Lewy body dementia, memory loss, and cognitive impairment including mild cognitive impairment (MCI).

Disclosed herein is an isolated stem cell or population thereof that comprises oncolytic herpes simplex virus (oHSV). Examples of possible stem cells include mesenchymal stem cells (MSC), neuronal stem cells and induced pluripotent stem cells. Various forms of the oHSV are disclosed. Also disclosed are methods of treating brain cancer in a subject by administering the stem cells containing oHSV to the subject to deliver the oHSV to brain cancer cells in the subject. The method is for the treatment of primary brain cancer and secondary metastatic brain cancer.

Disclosed are novel modified or engineered oncolytic viruses comprising an esRAGE gene and methods for using said oncolytic virus for the treatment of a cancer.

This application provides, in part, methods and compositions for decreasing the immunogenicity of cell therapies (e.g., CAR-T cell therapies) using inhibitors of transporter associated with antigen processing (TAPi) and oligonucleotides that decrease the expression of an immunogenic proteins (e.g., MHC Class I and Class II).

The present disclosure provides, among other things, methods for using presenilin based gene therapy to treat neurodegenerative dementia including, but not limited to Alzheimers disease, frontotemporal dementia, frontotemporal lobar degeneration, Picks disease, Lewy body dementia, memory loss, and cognitive impairment including mild cognitive impairment (MCI).
