French CNRS researchers with a group of scientists from Institut Curie and INSERM have used two-photon microscopy to demonstrate, for the first time in vivo and real-time, how T lymphocytes infiltrate a solid tumour in order to fight it. How is a tumour destroyed by T lymphocytes? This scenario has recently been visualised and published in the journal of Experimental Medicine.
Specific mutations in a viral protein, the polymerase, contribute to the ability of the bird influenza virus to jump the species barrier to humans. Researchers from the European Molecular Biology Laboratory (EMBL) in Grenoble and Heidelberg, the Institut de Biologie Structurale (IBS) and the Unit of Virus Host Cell Interactions (UVHCI)*, both in Grenoble, have now produced the first 3-D image of part of this key protein.
Academics have found, for the first time, smells from healthy feces and people with infectious diarrhea differ significantly in their chemical composition and could be used to diagnose quickly diseases such as Clostridium difficile (C. Diff.).
