The biological activity of new tuftsin derivatives - induction of phagocytosis
PublicationFagocytoza odgrywa ważną rolę w ochronie organizmu przed różnymi mikroorganizmami. Proces ten może być indukowany przez różne czynniki np. endogenny immunomodulator jakim jest tuftsyna czy muramylo-dipeptyd (MDP), najmniejszy syntetyczny glikopeptyd bakteryjnej ściany komórkowej. Zsyntetyzowano nowe analogi MDP i nor-MDP z tuftsyną i retro-tuftsyną, które są zdolne do indukowania fagocytozy. Najbardziej obiecujące okazały się dwa...
