The present disclosure relates to the production of transmissible vims defective interfering particles (DIPs), particularly those of dengue virus as well as methods of their production. The DIPs have particular utility as immunogenic compositions and vaccines.

Disclosed herein is an amyloid β accumulation and/or aggregation inhibitor. A technique for inhibiting amyloid β accumulation and/or aggregation by concurrently introducing Nurr1 and Foxa2 genes and introducing the co-expression of the genes is also provided. When used, the composition can be applied to the prevention or treatment of a neurodegenerative disease caused by amyloid β accumulation and/or aggregation, such as Alzheimer's disease.

Lentiviral packaging cells and methods for producing the same are provided herein. Specifically, lentiviral packaging cells capable of producing lentiviral vector suitable for use in clinical trials are provided. Methods for producing lentiviral packaging cells capable of producing lentiviral vector suitable for use in clinical trials are described.

The present disclosure provides chimeric antigen receptors (CARs), particularly CARs that have enhanced antitumor properties and/or can be regulated by safety switches. Also provided are polypeptides of the CARs and other related molecules, polynucleotides, vectors, and cell compositions comprising the same. Pharmaceutical compositions comprising the polypeptides, polynucleotides, vectors, or cells of the present disclosure, and their uses in treating a cancer in a subject are also provided.

Disclosed is a method for administering a transgene into a fibroblast in a subject comprising: a) providing a herpes simplex virus (HSV) comprising a recombinant herpes simplex virus genome, wherein said recombinant herpes simplex virus genome comprises one or more transgenes encoding a polypeptide to be expressed in said fibroblast; and b) providing a pharmaceutically acceptable carrier; wherein said HSV has reduced cytotoxicity as compared to a wild-type herpes simplex virus.

The present invention provides highly efficient methods, and compositions related thereto, for generating high titer human antibodies or antibody fragments thereof in a mammalian subject. The methods comprise administering a virus or virus-like particle to a mammal comprising heterologous immune cells and isolating a population of immunoglobulin-producing cells from the mammal, thereby producing the antibodies or antibody fragments thereof.

Provided herein are compositions, methods, kits and systems for treating cells, tissues and subjects to alter age-related biology (e.g., to study or to treat age-related diseases and conditions). In particular, provided herein are compositions, methods, and uses for inhibition or modification of sialic acid or its cognate receptor to restore phagocytosis in aged cells.

The present invention relates to the field of the production of lentiviral vectors (LV) for gene therapy. More particularly, the invention relates to a system to obtain the stable integration of a Self Inactivating (SIN) lentiviral transfer vector into a packaging cell line. The SIN lentiviral transfer vector is integrated using a DNA fragment containing the Inverted Terminal Repeats (ITR) of Adeno Associated Virus (AAV), thus obtaining the stable producer cell line for SIN lentiviral vectors.
