Abstract

Den foreliggende oppfinnelse vedører nøytrale, vandige leselige /3-glukaner som har potente og spesifikke immunolo- giske effekter uten å stimulere produksjonen av visse cyto- kiner, preparater som inneholder de nye /3-glukaner, og en ny fremstillingsfremgangsmåte for disse. Det noytrale, vandige løselige /3-glukanpreparat har høy affinitet for 0-glukan- reseptoren på humane monocytter, og beholder to primære biolo- giske (eller immunologiske) aktiviteter, (1) økningen av mikrobicid aktivitet hos fagocyttceller, og (2) monocytt, neutrofil og blodplatehemopoietisk aktivitet. Ulikt løselige glukaner beskrevet i tidligere teknologi, vil det nøytrale, vandige løselige /3-glukan ifølge denne oppfinnelse verken indusere eller prime IL-1/3 og TNFa-produksjon in vitro og in vivo. Sikre og virksomme preparater av nøytralt, vandig løselige /3-glukan ifølge den foreliggende oppfinnelse kan anvendes i terapeutiske og/eller profylaktiske behandlings- regimer av mennesker og dyr for å øke deres immunrespons, uten å stimulere produksjonen av visse biokjemiske mediatorer (f.eks. IL-1/3, TNFa) som kan forårsake skadelige side- virkninger, slik som feber og betennelse.
