Samenwerkende bacteriën offeren zichzelf op voor kolonie
Net zoals mieren, termieten en bijen, werken sommige bacteriën ook samen in een groep. Daarbij is er sprake van een strikte taakverdeling, zodat de groep als geheel weerbaar is tegen gevaren van buitenaf. Onderzoekers hebben nu ontdekt dat een deel van sommige bacteriën zich wel heel erg in dienst stellen…

Macrophages inhibit human osteosarcoma cell growth after activation with the bacterial cell wall derivative liposomal muramyl tripeptide in combination
CONCLUSION: This study demonstrates that human macrophages can be induced to exert direct anti-tumor activity against osteosarcoma cells. Our observation that the induction of macrophage anti-tumor activity by L-MTP-PE required IFN-gamma may be of relevance for the optimization of L-MTP-PE therapy in…
