Gas permeability of biological membranes
We have shown that the cell membrane of red blood cells has a high permeability for CO2 because it is equipped with special "CO2 channels". In this case, we have identified the rhesus protein (which also has blood group properties) and aquaporin-1 (which is also a carrier of the blood group property Colton). Both proteins increase the CO2 permeability of the erythrocyte membrane more than tenfold. The two proteins probably have the same effect on other gases, including O2. Other cell membranes lacking these two proteins have much lower gas permeabilities. We are investigating the molecular mechanism of CO2 permeation through these channels using molecular biological methods by expressing the proteins and specifically produced mutants in cell culture and by studying rhesus and aquaporin-1-deficient erythrocytes from human and mouse blood.

Plasticity of skeletal muscle
Different types of stress, such as continuous stress (e.g. marathon) or short-term maximum stress (e.g. sprint), lead to characteristic adaptations of the skeletal muscle after a longer period of time, which makes it better able to meet these requirements. One example is the "white-red transformation", in which "fast" muscle fibers are transformed into "slow" muscle fibers as a result of prolonged exertion. Due to a change in the isoforms of the contractile proteins and metabolic enzymes (with a preference for oxidative metabolism), these fibers are considerably less fatiguable than fast fibers. We investigate the signals and signaling cascades that are responsible for these adaptations of skeletal muscle. These investigations are mainly carried out on muscle cells in culture.

The role of myoglobin for oxygen transport in heart and skeletal muscle
From measurements of the diffusivity of myoglobin in intact heart and skeletal muscle cells, we deduce the quantitative role of myoglobin as an intracellular O2 store on the one hand and as an intracellular "O2 transporter" on the other. Theoretical calculations and numerous experimental findings show that myoglobin is of comparable importance as a store and as a transporter. However, myoglobin becomes important mainly under non-steady-state conditions. Examples are the systolic phase of the heart, during which the blood supply to the wall of the left ventricle is largely suspended, or in skeletal muscle at the beginning of intensive contractile activity. Bridging these periods of poor O2 supply appears to be the main task of myoglobin.

The elimination of lactic acid from skeletal muscle and the role of muscular membrane-bound carbonic anhydrases
By studying the muscles of knockout mice for the membrane-bound carbonic anhydrases CA IV, CA IX and CA XIV, we were able to show that the release of lactic acid formed in the muscle cell occurs in two ways: 1) the lactic acid diffuses through the sarcoplasm and leaves the cell with the help of the sarcolemmal lactic acid carrier (MCT). This process is supported by carboanyhydrases IV and XIV; 2) the lactic acid is released into the intracellular network of T-tubules at the site of its production. These can transport the lactic acid considerably faster to the cell surface, which means that they contribute very effectively to the release of lactic acid from the muscle fiber despite the small volume of the T-tubules. In addition to their role in electromechanical coupling, the T-tubules therefore play an important role as a "drainage system of the muscle cell" for lactic acid.
