A joint research team from the A.N. Frumkin Institute of Physical Chemistry & Electrochemistry (RAS), NUST MISIS, and MIPT, as well as participants from several other research centers, have described the biophysical principles of influenza’s infiltration into the body’s cells. The researchers have created a theoretical model describing the mechanical properties of the lipid membranes of both the virus and the targeted cells, making it possible to connect the mechanisms of membranes with cell resistance. A series of three articles (1, 2, 3) containing the new research have been published in special editions of the International Journal of Molecular Sciences.
