摘要:
Malignant tumors that are resistant to conventional therapies represent significant therapeutic challenges. An embodiment of the present invention provides a second generation oncolytic virus rQNestin34.5v2 with less toxicity 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 glioblastoma, as well as other cancers.
摘要:
Adeno-associated virus (AAV) Clade F vectors or AAV vector variants (relative to AAV9) for precise editing of the genome of a cell and methods and kits thereof are provided. Targeted genome editing using the AAV Clade F vectors or AAV vector variants provided herein occurred at frequencies that were shown to be 1,000 to 100,000 fold more efficient than has previously been reported. Also provided are methods of treating a disease or disorder in a subject by editing the genome of a cell of the subject via transducing the cell with an AAV Clade F vector or AAV vector variant as described herein and further transplanting the transduced cell into the subject to treat the disease or disorder of the subject. Also provided herein are methods of treating a disease or disorder in a subject by in vivo genome editing by directly administering the AAV Clade F vector or AAV vector variant as described herein to the subject.
摘要:
The present invention relates, in general, to human immunodeficiency virus (HIV), and in particular to a vaccine for HIV-1 and to methods of making and using same.
摘要:
Provided herein are nucleic acid sequences that encode novel consensus amino acid sequences of herpes virus antigens, as well as genetic constructs/vectors and vaccines expressing the sequences. Also provided herein are methods for generating an immune response against herpes virus using the vaccines that are provided.
摘要:
The invention provides HSV antigens and epitopes that are useful for the prevention and treatment of HSV infection. T-cells having specificity for antigens of the invention have demonstrated cytotoxic activity against cells loaded with virally-encoded peptide epitopes, and in many cases, against cells infected with HSV. The identification of immunogenic antigens responsible for T-cell specificity provides improved anti-viral therapeutic and prophylactic strategies. Compositions containing antigens or polynucleotides encoding antigens of the invention provide effectively targeted vaccines for prevention and treatment of HSV infection.
摘要:
A mutant herpesvirus that has a mutated gene that encodes a mutant infected cell protein 0 (ICPO) can be used in therapeutic methods as well as in diagnostics and research experiments. The encoded mutant ICPO protein can be altered in one or more regions of ICPO that are substantially conserved between two or more herpesviruses and/or within a phosphorylation region. The mutant herpesvirus can be substantially avirulent and immunogenic.
摘要:
An I-CreI variant, wherein at least one of the two l-Crel monomers has at least two substitutions, one in each of the two functional subdomains of the LAGLIDADG core domain situated from positions 26 to 40 and 44 to 77 of I-CreI, said variant being able to cleave a DNA target sequence from the genome of a non- integrating virus, inparticular herpes simplex virus (HSV) or Hepatitis B virus (HBV) for use in genome engineering and for in vivo and ex vivo (gene cell therapy) genome therapy as well as the treatment of a virus infection.
摘要:
Compositions containing HLA-A2 binding-peptides and adjuvants are described as well as methods of using such compositions to stimulate immune responses to herpes simplex virus-2 infection in mammals.
摘要:
Processes vectors and engineered cell lines for large-scale transfection and protein production in mammalian cells, especially Chinese Hamster Ovary (CHO) cells are described in which transfection efficiencies are realized through the use of a single vector system, the use of functional oriP sequences in all plasmids, the use of codon- optimized Epstein-Barr virus nuclear antigen-1 (EBNA1 ) constructs the use of a fusion protein between a truncated Epstein-Barr virus nuclear antigenen-1c (EBNA1c) protein and a herpes simplex virus protein VP16, the use of a 40 kDa fully deacetylated poly(ethylenimine) as a transfection reagent, the use of co-expression of a fibroblast growth factor (FGF) and/or the use of protein kinase B to potentiate heterologous gene expression enhancement by valproic acid (VPA).
