Abstract:
A conditionally live virion and method for making the same whereby the viral DNA or RNA is modified so that the virion is incapable of replication unless a protein supplement is added to the expression system. The expression system is either a traditional cell culture or cell free expression system suitable for self assembly of viral particles. Both expression systems require the addition of viral proteins either for replication or assembly of the replication incompetent virion. The conditionally live viron is then used for creating a vaccine with three fold . immunogenic properties that are elicited by 1) the whole intact replication incompetent virus; 2) the conditionally live virion temporally resuscitated by addition of protein supplements; and 3) the protein supplement itself acting as a subunit vaccine.
Abstract:
An antigenic and immunogenic composition of predetermined inactivated strains of human immunodeficiency virus (HIV) is disclosed. Inactivation is through psoralen and ultraviolet radiation; the composition is rendered more effective by the removal of structural features of HIV that interfere with immune response. In particular, sialic acid is removed to enhance immune recognition of the composition and to impair Complement Factor H binding. CD55 and CD59 are also removed to prevent the binding of Complement Factor H. Determination of strains for inactivation may be though immunotherapeutic genotyping or probabilistic assessment of risk of exposure.
Abstract:
An immunogenic composition able to provide an immune response to Human Complement Factor H binding on one or more HIV glycoproteins is disclosed, which is characterized by at least one binding site epitope of the glycoproteins. Such immunogenic composition wherein the glycoprotein comprises gp120, gp4l, or both glycoproteins gp120 and gp4l is hereby disclosed. Sialic acid is removed to enhance immune recognition of the composition and to impair Factor H binding. A medication having an inhibitive action on autoimmune response by specific inhibition of the cleavage of C3b by Factor H into inactive cell fragments.
Abstract:
The present invention relates to an immunogenic composition. More particularly, the present invention is a composition directed to eliciting an immune response to at least one binding site of Cyclophilin A on the HIV capsid protein. The present invention contemplates three categories of embodiments: protein or protein fragments, messenger RNA, or DNA/RNA. DNA/RNA compositions may be either naked or recombinant. The present invention further contemplates use with a variety of immune stimulants.
