Klaus Aktories

from Wikipedia, the free encyclopedia

Klaus Aktories (born August 4, 1948 in Wanne-Eickel ) is a German physician and pharmacologist . His research interests are in signal transduction by GTPases and their interaction with bacterial toxins .

Life

Aktories studied pharmacy and medicine in Frankfurt am Main . Under the guidance of Hans-Dieter Taubert , he wrote his dissertation The Influence of Different Types of Hormonal Contraceptives on the Ovarian Cycle and was awarded a Dr. med. PhD . At the Ruprecht-Karls-Universität Heidelberg he was awarded a Dr. rer. nat. PhD ("Inhibition of fat cell adenylate cyclase by hormonal factors and drugs"). From 1981 to 1984 Aktories worked with Günter Schultz at the Pharmacological Institute of Heidelberg University and completed his habilitation in 1983 on the subject of hormone-sensitive GTPases - studies on the regulation and role of GTPases in the hormonal control of adenylate cyclase .

From 1985 to 1989 and 1989 to 1991 Aktories held an extraordinary professorship in Gießen and Essen. In 1991 he switched to a full professorship at Saarland University . In 1995 he was selected from 57 applicants for Chair I at the Institute for Experimental and Clinical Pharmacology and Toxicology at the University of Freiburg and appointed.

The work of Klaus Aktories contributes significantly to the understanding of the mode of action of bacterial protein toxins. In 1986 he and his colleagues were able to show that the botulinum C2 toxin destroys the polymer structure of actin through ADP ribosylation. The Clostridium difficile toxins A and B, the zyototoxic-necrotizing factor 1 from E. coli strains and the toxins from Photorhabdus luminescens also lead to a destruction of the cytoskeleton via modification of Rho-GTPases .

An overview article published in 2005 gives a deeper insight into Klaus Aktories' research.

Together with others, Aktories is the publisher of the German-language standard work General and Special Pharmacology and Toxicology founded by Wolfgang Forth .
