Not only chemistry plays a role in the docking of antigens to the T-cell; micromechanical effects are important too. Submicrometer structures on the cell surface act like microscopic tension springs. Tiny forces that occur as a result are likely to be of great importance for the recognition of antigens. It has now become possible to observe these forces directly using highly developed microscopy methods.
