The lipid bilayer of the cell membrane constitutes the boundary between the cell and the rest of the world -- and, as such,
acts as the key gateway for communications between the cell and its environment. A special collection of articles in Science and its online companion Signal Transduction Knowledge Environment (STKE) explores the current understanding of ion and macromolecule
transport across these semipermeable membranes. In Science, Review articles examines the mechanisms that cells use to allow proteins, DNA, and ions to cross biological membranes both
within the cell (for example, among organelles) and in transfers between the cell and its environment. And a set of articles
in STKE addresses how information is transmitted across cell membranes to contribute to cell signaling processes.
