Abstract:
The present disclosure relates to adenovirus protein modifications to augment immune response to a transgene of a recombinant adenovirus and to circumvent pre-existing anti-adenovirus immunity. Some embodiments are directed to a recombinant adenovirus derived from a recombinant adenovirus plasmid vector, wherein the recombinant adenovirus plasmid vector comprises a nucleotide sequence encoding a Plasmodium circumsporozoite protein, or antigenic portion thereof, operably linked to a heterologous promoter and a modified capsid or core protein, wherein an immunogenic epitope of Plasmodium circumsporozoite is inserted into or replaces at least part of a capsid or core protein. Other embodiments are directed to a pharmaceutical composition or a malaria vaccine composition comprising a recombinant adenovirus according to the above embodiments. Further embodiments include a method of treating, preventing, or diagnosing malaria, comprising administering a therapeutic amount of the pharmaceutical composition or malaria vaccine composition in accordance with the above embodiment.
Abstract:
The invention is directed to novel synthetic C-glycolipids that selectively induce a ThI -type immune response characterized by enhanced IL- 12 secretion and increased activation of dendritic cells. The compounds of the invention are thereby useful in treating infections, cancers, cell proliferative disorders, and autoimmune diseases, both directly and as adjuvants.
