Tumor cells often evade an immune response, e.g., by reducing or eliminating MHC expression and/or IFN-signaling, which enables uncontrolled growth. We demonstrate herein that antibody-based immunotherapy in combination with IL2 administration is an effective therapy against such resistant tumors. Specifically, the present disclosure relates to methods of treating a subject with cancer that is at least partially resistant to an MHC-dependent T cell response comprising administering to the subject: a. a polypeptide comprising IL2 or a functional variant thereof or a polynucleotide encoding a polypeptide comprising IL2 or a functional variant thereof; and b. antibody-based immunotherapy.

Compositions and methods are described for the delivery of a fully human-glycosylated (HuGly) α-L-iduronidase (IDUA) to the cerebrospinal fluid of the central nervous system (CNS) of a human subject diagnosed with mucopolysaccharidosis I (MPS I).

A device for treatment of cells with particles is disclosed. The device includes a semi-permeable membrane positioned between two plates, the first plate defining a first flow chamber and comprising a port, a flow channel, a transverse port, and a transverse flow channel, the first flow chamber constructed and arranged to deliver fluid in a transverse direction along the first side of the semi-permeable membrane, the second plate defining a second flow chamber and comprising a port. A method for transducing cells is disclosed. The method includes introducing a fluid with cells and viral particles into a flow chamber adjacent a semi-permeable membrane such that the cells and the viral particles are substantially evenly distributed on the semi-permeable membrane. The method also includes introducing a recovery fluid to suspend the cells and the viral particles, and separating the cells from the viral particles. A method of activating cells is disclosed.

Provided herein are compositions, kits and methods related to permitting a human or non-human primate subject to receive multiple doses of recombinant adeno-associate virus (rAAV) vectors. In some aspects, provided herein are methods comprising administering an anti-CD20 antibody, optionally in combination with an mTOR inhibitor, to the subject to permit multiple doses of an rAAV vector to be administered.

Provided herein are methods for managing host immune responses to improve therapeutic outcomes in adeno-associated virus (AAV)-mediated gene therapy. Such methods may include administering a recombinant adeno-associated vims (rAAV) to a subject following administration of a CD 19 inhibitor, e.g., an anti-CD 19 antibody. The methods described herein can facilitate improved transgene expression, help overcome pre-existing NAbs, and/or permit redosing with the same or substantially similar rAAV or transgene.

Compositions and methods are described for the delivery of recombinant human iduronate-2-sulfatase (IDS) produced by human neuronal or glial cells to the cerebrospinal fluid of the central nervous system (CNS) of a human subject diagnosed with mucopolysaccharidosis II (MPS II).

Polynucleotides encoding peptides, proteins, enzymes, and functional fragments thereof are disclosed. The polynucleotides of the disclosure can be effectively delivered to an organ, such as the lung, and expressed within cells of the organ. The polyribonucleotides of the disclosure can be used to treat a disease or condition associated with a gene of the ATP-binding cassette (ABC) family, such as ABCA3.

The present disclosure provides, among other aspects, codon-altered polynucleotides encoding Factor VIII variants for expression in mammalian cells. In some embodiments, the disclosure also provides mammalian gene therapy vectors and methods for treating hemophilia A. In some embodiments, the present disclosure provides methods for dosing a hemophilia A patient with a polynucleotide, e.g., a codon-altered polynucleotide, encoding a Factor VIII polypeptide.

A method for optogenetics experiments, based on wavefront shaping and including: calculating the transmission matrix between an input end and an output end of the multimode fiber under a fixed shape; implanting the output end into an intracranial space of an experimental subject; and performing wavefront compensation to a light to be input into the input end, according to the spatial position of the optical stimulation and the transmission matrix of the multimode fiber, to form a compensated expanded light, and inputting the compensated expanded light from the input end into the multimode fiber, such that the compensated expanded light, after being transmitted by the multimode fiber to the output end and output from the output end, is capable of focusing at the spatial position of the optical stimulation.
