Picture a row of heads facing the outside of the cell . Cell Membrane Definition The researchers found that after HIV docks onto a host cell, it dramatically lowers the energy required for a cell membrane to bend, making it easier for the virus to infect immune cells. The finding, in press in Biophysical Journal, . Furthermore, our studies indicate that collagen XXIII is localized in lipid rafts in the plasma membrane and that ectodomain shedding is altered by a cholesterol-dependent mechanism. Moreover, newly synthesized collagen XXIII either is .
