Identification of effective targets alleviating the programmed cell removal (PrCR) of tumor cells by macrophages is of very high interest. The present inventors have identified that the cyclin-dependent kinase inhibitor p21 protein is a strong regulator of the macrophage-mediated PrCR. Also, they showed that the adoptive transfer of p21 overexpressing monocytes induces macrophage PrCR and transition from an anti-inflammatory to a pro-inflammatory phenotype in vivo, delays cancer progression and increases significantly the overall survival of mice engrafted with cancer cells. The present invention therefore concerns therapeutic compositions comprising monocytes that over-express the cyclin-dependent kinase inhibitor p21 protein, and their use for treating mammals suffering from cancer, especially leukemia.

A CRISPR-Cas system targeting a genomic target sequence in a eukaryotic cell and capable of promoting death of the eukaryotic cell is provided. A viral particle and an isolated eukaryotic cell including the CRISPR-Cas system, a method that uses the CRISPR-Cas system, and use of the CRISPR-Cas system as a medicament in the treatment of neoplastic diseases are also provided.

The present invention provides the use of a packaging cell line for the production of VSV-G pseudotyped retroviral vector particles or virus like particles thereof, wherein said packaging cell line is negative for Low-Density Lipoprotein Receptor (LDLR), optionally said packaging cell line stably expresses VSV-G. A method for producing said VSV-G pseudotyped retroviral vector particles or virus like particles thereof is disclosed as well as said particles obtained by said method.

Disclosed herein are virus-like particle (VLP)-based bivalent vaccine compositions. The compositions may comprise a spherical retroviral Group—specific Antigen (“Gag”) protein core and at least two Ebola glycoproteins. The at least two Ebola glycoproteins may be located at the exterior surface of the spherical Gag protein core, such that the VLP-based vaccine presents at least two Ebola glycoprotein antigens. In one aspect, the at least two Ebola glycoproteins are a Zaire (EBOV) glycoprotein, and a Sudan (SUDV) glycoprotein.

The invention relates to a pharmaceutical composition for targeting drug delivery including gene delivery to lung tissue, comprising at least a therapeutic drug or gene associated to a syncytin protein, and its use in the prevention and/or treatment of lung diseases, in particular in gene therapy of said diseases using lentiviral vector particles or lentivirus-like particles pseudotyped with syncytin protein.

The present invention provides methods and compositions for treatment of hemophilia and other bleeding disorders in a subject in need thereof.

Embodiments relate to a method comprising (a) expressing a vector comprising a PSGL-1 (P-selectin glycoprotein ligand-1) or a mutant thereof in a VPC (virus producing cell); and blocking a virus infection by inactivating an infectivity of a released virions from the VPC; or (b) expressing a glycoprotein or a mutant thereof in the VPC; blocking the virus infection by preventing binding of the released virions to a target cell; inactivating infectivity of the released virions; and targeting a viral infection. Other embodiments relate to (1) a broad-spectrum anti-viral product comprising: a vector expressing a glycoprotein or a mutant thereof in a VPC; and blocking a virus infection by inactivating infectivity of a released virion from the VPC; and (2) a vaccine comprising a viral particle is configured to a live attenuated or an inactivated or a non-infectious, wherein the viral particle are produced in a VPC.

In one aspect, the invention relates to methods and compositions for determining migration of a virus particle to the nucleus of a cell. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The present disclosure relates generally to methods and compositions for activating gamma-delta (GD) T cells. Such methods and compositions can be used to treat cancer.
