Wechselspiel von zwei Immunstoffen zur Abwehr bakterieller Infektionen identifiziert

Unser Immunsystem muss ständig Bakterien und Viren abwehren und dabei eine kritische Gratwanderung zwischen Über- und Unterreaktion schaffen, ähnlich wie Daedalus und Ikarus in der griechischen Mythologie, die weder zu hoch noch zu tief fliegen dürfen, um ihrem Gefängnis zu entfliehen. ImmunbiologInnen um Pavel Kovarik erforschen, was beim Balanceakt des Immunsystems auf molekularer Ebene passiert. Die WissenschafterInnen der Max F. Perutz Laboratories der Universität Wien und der Medizinischen Universität Wien zeigen, dass bei der Abwehr von Gruppe A-Streptokokken – Bakterien, die Mandelentzündung, aber auch schwere und zum Teil tödliche Infektionen auslösen können – ein perfekt abgestimmtes Wechselspiel von zwei Immunstoffen eine Schlüsselrolle spielt: Die Moleküle IL-1β und Interferon vom Typ I steuern die Stärke der Immunreaktion. Die Ergebnisse bieten neue Ansätze zur Behandlung schwerer Streptokokkeninfektionen.

A team of researchers from have discovered that lycopene – the red pigment in tomatoes – is extremely successful at guarding against the harmful effects of radiation.

Dr Ruth Edge from The University of Manchester, together with her colleagues Professor George Truscott from Keele University and Professors Fritz Boehm & Christian Witt from Berlin, undertook a study of lycopene (one of the carotenoids – plant pigments found in many fruits and vegetables) and its effectiveness at protecting against radiation at the University of Manchester’s Dalton Cumbrian Facility, part of the Dalton Nuclear Institute.

AUSTIN, Texas — Researchers at The University of Texas at Austin have discovered that a type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous. The finding, published in the Proceedings of the National Academy of Sciences, contributes to a growing body of research that implicates the environment around a cancer in its spread — an area of study that holds promise for new alternatives to treat the disease.

Approach borrows from technique of inhibiting protein fibers that cause Alzheimer’s and Parkinson’s diseases

UCLA scientists have developed a promising novel method to treat gynecologic tumors. The approach focuses on a protein called p53, which is commonly mutated in women who have high-grade serous ovarian cancer, the deadliest form of reproductive cancer. In many women with the disease, the cancer is very advanced by the time it is diagnosed and is therefore difficult to treat. (more…)
