IMMUNOGENIC COMPOSITION AND METHOD OF DEVELOPING A VACCINE BASED ON FACTOR H BINDING SITES.

摘要

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.
