The 50th anniversary of the European Society for Muscle Research: a journey through half a century of scientific advances.

Abstract

The European Society for Muscle Research (ESMR) started in 1971 as "European Muscle Club" in a joint initiative of Marcus Schaub, Eduard Jenny and Rudolf Billeter (Zurich), Caspar Rüegg (Heidelberg), Jean Légér (Montpellier), Bernard Swynghedauw (Paris), George Maréchal (Brussels), Gabriel Hamoir (Liège), and Endre Biró (Budapest). Since 1972, local organizers took care of muscle conferences held yearly in different European countries and in Israel in 1987. One of the goals was to establish contacts and collaborations between scientists on both sides of the Iron Curtain. Starting as an informal club, enthusiastically guided by Marcus Schaub as secretary (1971-1995) and later by Ger Stienen (1996-2005), Anders Arner (2006-2017) and Wolfgang Linke (2018-), the ESMR meetings steered international collaborations. The meetings witnessed the remarkable advancement of the insight in skeletal, smooth and cardiac muscle structure and function. In the five decades, the thin and thick filament structure has been resolved to the atomic level, the mechanism of acto-myosin energy transduction and force generation as well as its regulation have been elucidated. The molecular basis of striated and smooth muscle diversity has been found in the existence of multiple protein isoforms. The transcriptional, translational and post-translational regulations which give rise to adaptive responses of muscle tissue have been revealed. Many new players entered the field, such as titin, the ryanodine receptor and several signalling factors. Substantial progress has also been made in the identification of the pathogenesis of many hereditary muscle diseases such as Duchenne MuscularDystrophy and Hypertrophic Cardiac Myopathies.
