Werner Goebel

Werner Goebel (born 19 September 1939 in Siemianowice Śląskie, Upper Silesia) was a German microbiologist who held the chair of microbiology at the University of Würzburg from 1974 to 2007 and became one of the leading figures in the molecular genetics of Listeria monocytogenes, the bacterium that causes listeriosis.¹ His laboratory identified and characterized the bacterium's principal virulence factors, including the hemolysin gene hly (listeriolysin O) and its positive regulator PrfA, and he led the German contribution to the complete sequencing of the L. monocytogenes genome announced in 2000.²^•³^•⁴

Early life and education

Goebel studied chemistry at the University of Tübingen from 1958 to 1963 and received his doctorate in 1965.

Career and academic positions

Later DFG funding records list his address as the Max-von-Pettenkofer-Institut für Hygiene und Medizinische Mikrobiologie of the Ludwig-Maximilians-Universität München, indicating an affiliation in Munich in the later phase of his funded work.⁶

Scientific contributions: Listeria virulence, listeriolysin O, and PrfA

The hemolysin gene. Studies by the Würzburg group and others led between 1986 and 1989 to the discovery of the hemolysin gene hly, the first virulence determinant to be identified and sequenced in Listeria species. The hemolysin, listeriolysin O, plays the key role in escape from destruction inside phagosomes, the prerequisite for intracellular bacterial proliferation.² A 1989 paper from the Institut für Genetik und Mikrobiologie der Universität Würzburg, with Martin Leimeister-Wächter and Trinad Chakraborty among the authors, cloned the listeriolysin gene from a weakly hemolytic but virulent L. monocytogenes strain in Escherichia coli K-12.⁷ The hly gene maps to a 9-kb chromosomal virulence gene cluster involved in functions essential to intracellular survival, and in the same period the internalin locus inlAB, encoding the first invasin described in a gram-positive bacterium, was identified and characterized.²

The regulator PrfA. In 1990 Goebel, with Leimeister-Wächter, Haffner, Domann, and Chakraborty, published in PNAS the identification of a gene that positively regulates expression of listeriolysin, the major virulence factor of L. monocytogenes (PNAS 87(21):8336–8340).³ The genetic evidence came from the mutant strain SLCC53, which is nonhemolytic and avirulent, and carries a 450-base-pair deletion located approximately 1,500 base pairs upstream of the listeriolysin gene.⁸ This regulator, PrfA, is the central transcriptional activator for the most important virulence genes of L. monocytogenes and is itself controlled in its synthesis and activity in complex ways.⁹

PrfA modulation by carbon metabolism. A DFG project running from 1998 to 2006, subproject B 01 of SFB 479, investigated how PrfA activity is modulated by PTS permeases, the sugar-transport systems of the bacterium. The work found that PrfA activity is strongly inhibited by glucose and other PTS substrates, and it disproved the hypothesized model in which modulation depended on the phosphorylation state of EIIA.⁹^•¹¹ The project used 13C-isotopologue metabolic analysis in primary murine bone-marrow macrophages and the J774 macrophage cell line to compare host-cell carbon metabolism during infection, and it produced reviews with his collaborators, including Götz, Eylert, Eisenreich, and Goebel, "Carbon metabolism of intracellular bacterial pathogens and possible links to virulence," Nature Reviews Microbiology 8:401–412 (2010).⁹

Goebel also co-authored the 2001 review "Listeria Pathogenesis and Molecular Virulence Determinants" in Clinical Microbiology Reviews.²

Genome sequencing and patho-biotechnology

On 12 April 2000, at a press conference at the "Genom 2000" congress in Paris, it was announced that the entire genome of L. monocytogenes had been deciphered, with scientists of the Würzburg Biozentrum including Goebel's group among the contributors. The work was carried out by an EU-funded consortium of ten research groups from France, Spain, and Germany, funded since 1998, and the genome comprises about 3,000 genes.⁴ The University of Marburg's 2006 prize announcement credits Goebel as a key initiator of the German genome network and states that in an international consortium he achieved the complete sequencing of the Listeria genome.¹

The same announcement describes the applied line of his later work: the "Patho-Biotechnologie" uses the ability of L. monocytogenes to infect cells of the immune system to develop novel live vaccines, a development in which Goebel was substantially involved, and he contributed to the BMBF competence network "PathoGenoMik" for pathogen genome research.¹ The Würzburg groups of Goebel, Jürgen Kreft, and Michael Kuhn received 500,000 DM over three years for the follow-up EU project REALIS on Listeria gene function.⁴

By the numbers

On the funding side, the DFG record documents individual projects, including the 1998–2006 SFB 479 subproject on PrfA regulation.⁹

Students, collaborators, and the Würzburg school

The 1989 listeriolysin cloning paper and the 1990 PNAS regulator paper carry the names of Leimeister-Wächter and Chakraborty alongside Goebel's.⁷^•³ Jürgen Kreft and Michael Kuhn led neighboring groups at the same chair in the genome-sequencing era.⁴ Later collaborators named in his ORCID record include Wolfgang Eisenreich, Thomas Rudel, and Jürgen Heesemann, with works such as "Differential regulation of the virulence genes of Listeria monocytogenes by the transcriptional activator PrfA" and studies of the carbon substrates used by L. monocytogenes in J774A.1 macrophages.¹⁰

Honors and recognition

Goebel was elected to the German National Academy of Sciences Leopoldina in 1988, in the Section Microbiology and Immunology, with his location listed as München.⁵ On 1 June 2006 he received the Emil von Behring Prize of the City of Marburg together with the microbiologist Gerhard Gottschalk; the university release describes him as one of the doyens of bacterial pathogenesis research worldwide.¹
