The present disclosure provides compositions and methods for cell transplantation therapy based on forced expression of an exogenous HLA-F protein in donor cells to be transplanted into a subject. In some embodiments, the donor cells express an exogenous chimeric HLA-F protein comprising an extracellular region comprising an HLA-F alpha 1 domain, an HLA alpha 2 domain, an HLA-F alpha 3 domain, a linker and a β2m protein.

Genetically modified non-human animals expressing human SIRPα and human IL-15 from the non-human animal genome are provided. Also provided are methods for making non-human animals expressing human SIRPα and human IL-15 from the non-human animal genome, and methods for using non-human animals expressing human SIRPα and human IL-15 from the non-human animal genome. These animals and methods find many uses in the art, including, for example, in modeling human T cell and/or natural killer (NK) cell development and function, in modeling human pathogen infection of human T cells and/or NK cells, and in various in vivo screens.

An isolated cytotoxic T-lymphocyte (CTL), said CTL being a tolerance inducing cell and substantially depleted of alloreactivity, and wherein said CTL does not comprise a central memory T-lymphocyte (Tcm) phenotype, the CTL being transduced to express a cell surface receptor comprising a T cell receptor signaling module, is disclosed. Methods of generating same and using same are also disclosed.

A method of treating cancer in a subject in need thereof includes administering in situ to the cancer a therapeutically effective amount of a virus or virus-like particle.

The invention describes a method and compounds for the prevention of immune responses towards allofactors, towards viral vectors used for gene therapy and gene vaccination, towards proteins to which subjects are naturally exposed, towards genetically-modified organisms and towards undesirable effects related to vaccine administration for allergic or infectious diseases.

The present invention provides modified stem cells (SCs) and use of the SCs to treat disease.

The present disclosure provides compositions and methods for cell transplantation therapy based on forced expression of an exogenous HLA-F protein in donor cells to be transplanted into a subject. In some embodiments, the donor cells express an exogenous chimeric HLA-F protein comprising an extracellular region comprising an HLA-F alpha 1 domain, an HLA alpha 2 domain, an HLA-F alpha 3 domain, a linker and a β2m protein.

This document relates to bioengineering and involves bioengineered thymus organoids and related humanized animal models. The thymus organoids and animal models have various commercial and clinical uses, including generating humanized antibodies, making antigen-specific human T cells, inducing transplantation tolerance, rejuvenating thymus functions, and modeling human diseases.

Malignant tumors that are resistant to conventional therapies represent significant therapeutic challenges. An embodiment of the present invention provides a new generation regulatable fusogenic oncolytic herpes simplex virus-1 that is more effective at selective killing target cells, such as tumor cells. In various embodiments presented herein, the oncolytic virus described herein is suitable for treatment of solid tumors, as well as other cancers.

Provided are use of an Echovirus 25 (ECHO25) or a modified form thereof, or a nucleic acid molecule comprising a genomic sequence or cDNA sequence of the ECHO25 or a modified form thereof, or a complementary sequence of the genomic sequence or cDNA sequence, in treatment of a tumor in a subject, and in the manufacture of a medicament for treatment a tumor in a subject.
