Molekulare und bioorganische Grundlagen des Sekundärstoffwechsels / SFB 369

Im Rahmen des Sonderforschungsbereichs werden die Analyse von Pilz- und Pflanzeninhaltsstoffen, ihre Biosynthese, die Regulation ihrer Biosynthese, die Signalfunktion solcher Metabolite und die Rolle von Sekundärmetaboliten im Stoffwechsel untersucht. Darüber hinaus wird die Entwicklung neuer und verbesserter NMR-Methoden und Rechenverfahren für die Strukturaufklärung vorangetrieben. Es wird erwartet, dass sich hieraus langfristig neue Ansätze für die Herstellung pharmazeutisch und landwirtschaftlich wirksa

Wachstum oder Parasitenabwehr? Wettbewerb um Ressourcen in Nutzpflanzen aus Land- und Forstwirtschaft / SFB 607

Ziel ist es, die Regulation der Ressourcenverteilung zwischen und innerhalb von Nutzpflanzen aus Land- und Forstwirtschaft sowie die hierbei, unter dem Einfluss pflanzlicher Konkurrenten, Wirt-Parasit-Interaktion und Mykorrhizen sich einstellenden stofflich-energetischen ,,Kosten-Nutzen-Bilanzen“ zu klären. Das ,,Dilemma“ der Pflanze, Primär- und Sekundärstoffwechsel im Spannungsfeld zwischen Wachstumsprozessen und effizienter Konkurrenz gegenüber Nachbarindividuen einerseits und der Parasitenabwehr anderer

Optimierte molekulare Bibliotheken zum Studium biologischer Erkennungsprozesse / FOR 299

Es sollen biologische Erkennungsprozesse unter Verwendung molekularer Bibliotheken untersucht werden. Nahziel ist die Bearbeitung ausgesuchter Modellbeispiele aus Immunologie, Zellbiologie und Strukturbiologie. Unter Verwendung von Peptid-Bibliotheken wird beispielsweise die Corticotropin Releasing Hormon Rezeptor-Wechselwirkung, die Interaktion von a2–Makroglobulin mit verschiedenen Zytokinen sowie die Spezifität der MHC-Peptid-Erkennung untersucht. Röntgenkristallstrukturanalyse, NMR und andere physikalis

Launch of Biosciences Federation

The Biosciences Federation, an umbrella organisation representing over 60,000 life scientists, will be launched today at the House of Lords.

The Federation has been formed by an amalgamation of the Institute of Biology and the UK Life Sciences Committee.

It has over 20 member societies, in disciplines as disparate as ecology and neuroscience.

The main aims of the Federation are to promote dialogue between life scientists and to provide a single coherent voice for bioscient

New study begins to unravel fate of toxic pollutants harbored in Arctic waters

An analysis of pesticides that accumulate in Arctic waterways is giving scientists insight into the fate of such pollutants once they settle in polar regions.

The Arctic holds a telltale record of how humans have used chemicals globally during the past several decades. These cold corners of the earth act as a sink of sorts – chemicals used in industry and agriculture worldwide slowly migrate to and settle there – in sizeable quantities – in water, snow, ice, soil and vegetation.

Discovering New Regulators Of The Immune System

In an attempt to find new regulators of the immune system, a team of researchers at Rigel Pharmaceuticals, Inc. have created a successful method for discovering molecules that are involved in signalling pathways. As published this week in the Journal of Biology, the team conducted a functional genome-wide screen and discovered novel modulators of T-cell receptor signalling that could aid in the development of drugs that target the immune response.

T cells are an integral part of the immune r
