Fachtierarzt für Physiologie.

Arbeitsgebiet: Psychoneuroimmunologie
Schwerpunkt: Schmerzempfinden
Fragestellung: Wie verändert sich das Schmerzempfinden von Tieren und Menschen bei Erkrankungen und wie wird es durch Medikamente (Analgetika), zell-basierte Therapieansätze (Stammzellen) oder körpereigene Mechanismen (Erwartung, Konditionierung) moduliert?
Mechanismen der peripheren und zentralen Sensibilisierung im Zusammenhang mit Veränderungen des Schmerzempfindens (in vivo, in vitro, ex vivo); Veränderungen der neuronalen Erregbarkeit (Ca2+-imaging); Modulation von TRP-Kanälen (TRPV1, TRPA1, TRPM8, TRPM3); Rolle lokaler Immun- und Glia-Zellen bei der Entzündungsantwort (z.B. Aktivierung von Mikroglia, Astrozyten); Expression und Freisetzung von Entzündungsmediatoren (z.B. Zytokine; RT-qPCR, ELISA, Bioassays); Aktivierung inflammatorischer Transkriptionsfaktoren (NF-kB, STAT3; Immunhistochemie); Einsatzmöglichkeiten von Zellkultur-Modellen in der Schmerzforschung im Sinne des 3R-Prinzips (Replace, Reduce, Refine); in vivo-Untersuchung des Schmerzempfindens bei Versuchstieren durch Verhaltenstests (mechanische/thermische Rückzugsschwelle, Spontanverhalten).
