POLYPRENYL PHOSPHATES AS ADJUVANTS, POLARIZING THE IMMUNE RESPONSE TO Th1

Abstract

Abstract. The attempts to decrease a toxic action of Freund complete adjuvant have led to development of new emulsion adjuvant compositions. More often they are based on metabolizable oil (squalene) with addition the Tween 80 (Polisorbate 80) as an emulsifier. The third component is an immunomodulator. Adjuvants, intended for prevention of virus infections, should include the immunomodulators polarizing the immune response to Th1. From this point of view adjuvant based on a colloidal solution prepared by means of the Tween 80 from polyprenyl phasphates of fir needles (Phosprenyl) can be rather perspective. The last one, as well as squalene, is constructed by isoprene links, but has them not 6, but 16 that essentially reduces its toxicity. The obtained data shows that Phosprenyl essentially enhances efficiency of vaccination in such virus infections as tick born encephalitis, bird flu, poliomyelitis and polarizes the immune response to Th1.
