Abstract
The present disclosure relates generally to the field of molecular virology, and particularly relates to nucleic acid molecules encoding a modified alphavirus virus viral genome or self-replicating RNA (srRNA) construct, recombinant cells and pharmaceutical compositions containing the same, as well as the use of such nucleic acid molecules, recombinant cells and compositions for production of desired products in cell cultures or in a living body. Also provided are methods for eliciting an immune response in a subject in need thereof, as well as methods for preventing and/or treating rabies virus infection.
Claims29
A nucleic acid construct comprising a nucleic acid sequence encoding a modified alphavirus genome or self-replicating RNA (srRNA), wherein at least a portion of the nucleic acid sequence encoding the viral structural proteins of the modified alphavirus genome or srRNA has been replaced by a coding sequence for a polypeptide construct comprising an envelope glycoprotein G of a rabies virus (RABV-G), a variant thereof, or an antigenic determinant of either thereof.
The nucleic acid construct of any preceding claim, wherein the envelope glycoprotein G is of a virulent rabies virus strain or an avirulent rabies virus strain.

The nucleic acid construct of any preceding claim, wherein the polypeptide construct comprises a molecular alteration that stabilizes the RABV-G, variant thereof, or antigenic determinant of either thereof.
The nucleic acid construct of any preceding claim, wherein the modified alphavirus genome or srRNA comprises no nucleic acid sequence encoding viral structural proteins.
The nucleic acid construct of any preceding claim, wherein the nucleic acid sequence encoding the polypeptide construct is operably linked to a promoter sequence.
The nucleic acid construct of any preceding claim, wherein the modified alphavirus genome or srRNA is of an alphavirus belonging to the VEEV/EEEV/WEEV group, or the SFV group, or the SINV group.
The nucleic acid construct of any preceding claim, wherein the nucleic acid sequence has at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to a nucleic acid sequence selected from the group consisting of SEQ ID NOS:
