The COVID-19 pandemic has highlighted how our small genetic differences can have a tremendous effect on how our bodies respond to disease. Researchers have created 3D maps of how enhancer sequences and genes interact in several types of immune cells. Their new study opens the door to understanding individual risk for diseases from asthma to cancer.

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.
