摘要:
An adenovirus is disclosed, having a capsid comprising a hexon protein of SAdV-42.1 or an amino acid sequence at least about 99% identical thereto, or a hybrid hexon protein. The capsid encapsidates a heterologous nucleic acid molecule carrying a gene sequence operably linked to expression control sequences which direct transcription, translation, and/or expression in a host cell, and further encapsidates 5' and 3' adenovirus cis-elements necessary for replication and encapsidation.
摘要:
A recombinant vector comprises simian adenovirus at least one SAdV-30 sequence and a heterologous gene under the control of regulatory sequences. A cell line which expresses simian adenovirus SAdV-30 gene(s) is also disclosed. Methods of using the vectors and cell lines are provided.
摘要:
A method of inducing a CD8+ T-cell response against a selected molecule by delivering the molecule via a recombinant simian adenovirus is provided. Also provided are methods of inducing interferon-alpha and interferon-beta by delivering a recombinant simian adenovirus to a subject. The methods of the invention are particularly well suited for prophylaxis and treatment of infections with human immunodeficiency virus and human papilloma virus, among others, and cancer therapy.
摘要:
The present invention provides a method of altering the specificity of an adenovirus vector. The method involves providing an adenovirus having a capsid with a modified adenovirus hexon protein. The modified adenovirus has a capsid comprising a hexon protein with a deletion in hypervariable region 1 and/or hypervariable region 4 of the hexon and an insert of an exogenous molecule therein.
摘要:
A method of prolonging gene expression by reducing immune response to a recombinant adeno-associated virus (AAV) bearing a desired gene administered into the muscle of a mammal is described.
摘要:
A system for generating viral vectors carrying two distinct expression cassettes is provided. The system utilizes a unique polyvalent transfer vector that permits efficient detection and selection of inserted expression cassettes.
摘要:
A method for providing an adenovirus from a serotype which does not grow efficiently in a desired cell line with the ability to grow in that cell line is described. The method involves replacing the left and right termini of the adenovirus with the corresponding termini from an adenovirus which grow efficiently in the desired cell line. At a minimum, the left terminus spans the (5') inverted terminal repeat, the left terminus spans the E4 region and the (3') inverted terminal repeat. The resulting chimeric adenovirus contains the internal regions spanning the genes encoding the penton, hexon and fiber from the serotype which does not grow efficiently in the desired cell. Also provided are vectors constructed from novel simian adenovirus sequences and proteins, host cells containing same, and uses thereof.
摘要:
The present invention provides a hybrid vector construct which comprises a portion of an adenovirus, 5' and 3' ITR sequences from an AAV, and a selected transgene. Also provided is a hybrid virus linked via a polycation conjugate to an AAV rep gene to form a single particle. These trans-infection particles are characterized by high titer transgene delivery to a host cell and the ability to stably integrate the transgene into the host cell chromosome. Also disclosed is the use of the hybrid vectors and viruses to produce large quantities of recombinant AAV.
摘要:
Methods for efficient production of recombinant AAV are described. In one aspect, three vectors are introduced into a host cell. A first vector directs expression of cre recombinase, a second vector contains a promoter, a spacer sequence flanked by loxP sites and rep/cap, and a third vector contains a minigene containing a transgene and regulatory sequences flanked by AAV ITRs. In another aspect, the host cell stably or inducibly expresses cre recombinase and two vectors carrying the other elements of the system are introduced into the host cell.
