Immune cells that operate by phagocytizing harmful bacteria, rely on their cytoskeleton for their ability to move and for their ability release molecules that attract other immune cells.Explain which parts of the cytoskeleton are involved in these two processes and how cytoskeletal proteins are able to help the cell move, and also release signaling molecules.
