Japanese scientist is broken a few days ago saw group of flu virus ribonucleic acid enzymatic inferior the construction that place ties between the unit, offerred new thinking to develop flu vaccine. Research organization of Japanese high-energy accelerator publishs news bulletin 29 days to say, armour flu H1N1 inferior model the ribonucleic acid polymerization of virus is enzymatic by 3 inferior unit composition, among them any inferior the unit is short of break, duplicate in flu virus the ribonucleic acid group that core effect produces in the process is enzymatic misfire. High-energy accelerator research organization and Japanese manage change researcher have the aid of the equipment of large and synchronous radiate of the institute, analysed 3 inferior in the unit " PA " and " PB " two inferior the structure that place integrates between the unit. Researcher discovered these two inferior the amino acid with unit appearance indispensable union incomplete radical, affirm this amino acid once incomplete radical produces mutation, block up two inferior the union of the unit, the active with enzymatic polymerization of flu virus ribonucleic acid also is reduced significantly. Bulletin says, before flu vaccine often is opposite a kind only inferior model virus is effective, and flu virus is very incidental mutation, cause the vaccinal and rapid invalidation that just excogitates probably. The group of virus ribonucleic acid that discovers this is enzymatic inferior the structure between the unit, in include avian flu virus inside a variety of inferior model flu virus interior is applicable to both or all, this conduces to development new-style vaccine, carry set back inferior the is united in wedlock to restrain a variety of flu virus directly hyperplasia of the unit.
