Abstract

Official abstract text for this publication.

Methods are described for predicting ancestral sequences for viruses or portions thereof. Also described are predicted ancestral sequences for adeno-associated virus (AAV) capsid polypeptides. The disclosure also provides methods of gene transfer and methods of vaccinating subjects by administering a target antigen operably linked to the AAV capsid polypeptides.

First claim

Opening claim text (preview).

What is claimed is: 1 . An adeno-associated virus (AAV) capsid polypeptide having the amino acid sequence shown in SEQ ID NO: 42. 2 . The AAV capsid polypeptide of claim 1 , wherein the AAV capsid polypeptide or a virus particle comprising the AAV capsid polypeptide exhibits about the same or a lower seroprevalence than does an AAV9 capsid polypeptide or a virus particle comprising an AAV9 capsid polypeptide. 3 . The AAV capsid polypeptide of claim 1 , wherein the AAV capsid polypeptide or a virus particle comprising the AAV capsid polypeptide is neutralized to a similar or lesser extent by human serum than is an AAV9 capsid polypeptide or a virus particle comprising an AAV9 capsid polypeptide. 4 . The AAV capsid polypeptide of claim 1 , wherein the AAV capsid polypeptide is purified. 5 . The AAV capsid polypeptide of claim 1 encoded by the nucleic acid sequence shown in SEQ ID NO: 43. 6 . A nucleic acid molecule encoding an adeno-associated virus (AAV) capsid polypeptide having the nucleic acid sequence shown in SEQ ID NO: 43. 7 . A vector comprising the nucleic acid molecule of claim 6 . 8 . A host cell comprising the vector of claim 7 . 9 . A purified virus particle comprising the AAV capsid polypeptide of claim 1 . 10 . The purified virus particle of claim 9 , further comprising a transgene. 11 . A method of gene transfer and/or vaccination with a transgene, the method comprising administering the virus particle of claim 10 to a subject in need of gene transfer or vaccination, wherein the virus particle exhibits about the same or a lower seroprevalence than does an AAV9 virus particle. 12 . The method of claim 11 , wherein the virus particle is neutralized to the same or to a lesser extent by human serum than is an AAV9 virus particle. 13 . A method of vaccinating a subject, the method comprising administering a target antigen operably linked to the AAV capsid polypeptide of claim 1 to a subject in need of vaccination, wherein the AAV capsid polypeptide exhibits about the same or a lower seroprevalence than does an AAV9 capsid polypeptide. 14 . The method of claim 13 , wherein the AAV capsid polypeptide is neutralized to the same or to a lesser extent by human serum than is an AAV9 capsid polypeptide.
