A team of scientists from MSU and the Institute of Theoretical and Experimental Biophysics of Russian Academy of Sciences (located in Pushchino) have studied the mechanisms of interaction between the Fas-ligand protein that causes cell death and a respective membrane receptor. To initiate cell death, the ligand needs to contact with a specific protein component of the cell—caveolin. If the caveolin-binding domain is removed from the molecule of Fas-ligand, cell death may be prevented. The results of the study were published in Cell Death & Disease.
