Embodiments relate to expressing or overexpressing P-selectin glycoprotein ligand-1 (PSGL-1) in human immunodeficiency virus (HIV) producing cells; isolating HIV particles from the HIV producing cells; and preparing the isolated HIV particles as a HIV vaccine. Embodiments relate to a HIV vaccine comprising live attenuated, inactivated, or non-infectious HIV particles. Embodiments relate to systems performing a method comprising administering a vaccine comprising live attenuated, inactivated, or non-infectious HIV particles to a subject in need of the vaccine; and treating or preventing one or more disease states in the subject resulting from HIV infection. Embodiments relate to expressing or overexpressing PSGL-1 in virus producing cells; and inhibiting viral infection; or inhibiting viral spreading; or inactivating viruses and virus producing cells; or producing non-infectious virion particles; or allowing the virus producing cells to produce non-infectious virions, isolating the virions, and preparing non-infectious virions, the virions being HIV particles.

The present invention provides compositions and methods for treating an ocular condition and/or disease. In particular, compositions and methods of the invention are directed to a gene therapy for treatment of an ocular condition and/or disease. One particular aspect of the invention provides a recombinant DNA comprising (i) a therapeutic gene, a functional counterpart of a defective gene associated with manifestation said ocular condition or disease, or a combination thereof; and (ii) a delivery vehicle adapted for delivering said gene of (i) to cells in target ocular area for treating said ocular condition or disease, said delivery vehicle comprising an adeno-associated virus (AAV) serotype.

Chimeric transmembrane immunoreceptors (CAR) which include an extracellular domain that includes IL-13 or a variant thereof that binds interleukin-13R2 (IL13R2), a transmembrane region, a costimulatory domain and an intracellular signaling domain are described.

The present invention relates to a method of preserving CD62L expression in a regulatory T cell (Treg) population that has been cryopreserved, comprising introducing a polynucleotide encoding a FOXP3 polypeptide into the Treg population prior to cryopreservation. The present invention also relates to a method of preserving CD62L in a Treg population after cryopreservation, comprising introducing a polynucleotide encoding a FOXP3 polypeptide into the Treg population and cryopreserving said Treg population. Furthermore, the present invention relates to the use of an exogenous polynucleotide encoding FOXP3 for the preservation of CD62L expression in a Treg population after cryopreservation, and to a cryopreserved engineered Treg, pharmaceutical compositions comprising the cryopreserved engineered Treg and to therapeutic uses thereof.
