Abstract

The mechanism of interaction of the copolymers N-vinylpyrrolidone-acrylic acid and N-vinylpyrrolidone-maleic anhydride with bovine serum albumin, influenza virus total surface antigen (haemagglutinin and neuraminidase), and the BCG protein fraction in the presence of divalent copper ions was investigated. Novel water-soluble triple polymer-metal complexes of the above protein antigens were formed. These complexes showed high immunogenicity and conferred high levels of immunological protection. Study of the replication of pathogenic influenza A virus in animal lungs showed that, in mice immunised with the triple complex containing surface glycoprotein influenza virus A antigens, reproduction of the homologous virus was sharply inhibited, and immunisation of B mice, exhibiting pronounced T-cell deficiency, with complexes containing the BCG protein fraction ensured development of a high level of protection with respect to BCG infection.

Avian Influenza: Innate Immune Adjuvant (ASM)

Adjuvants systems that are added to vaccines against avian influenza have be explored to enhance the innate immune system response against the virus. Here is the latest research on avian influenza and the innate immune adjuvant.
