Praxisrelevante Forschungsgebiete:
  • Research in our laboratory is focused on trying to better understand the complex interactions, at a molecular and cellular level, between stress and genetics that lead to the manifestation of multiple pathologies such as anxiety, reactive depression, neuronal loss, substance abuse and cognitive dysfunction in certain susceptible individuals. This effort is paralleled with investigations towards discovery and characterization of new pharmacological therapies – eventually aiming to counteract the deleterious consequences of acute and chronic stress
  • The Flor laboratory works mainly on the role of Metabotropic Glutamate Receptors (mGluRs, the G protein-coupled receptors for the mammalian main excitatory neurotransmitter L-glutamate) in conditions related to Chronic Stress, such as Anxiety, Depression and Substance Abuse.

Praxisrelevante aktuelle Projekte:
  • mGluR2/3, mGluR5 and mGluR7 are crucially involved in the regulation of physiological processes involved in acute stress and fear/anxiety-related behaviours. However the underlying neurobiochemical, molecular, and cellular pathways are insufficiently understood. Our future research is intended to shed light on these topics!
  • Although mGluR2/3, mGluR5 and mGluR7 are emerging as fine-tuning regulators of neuroendocrine function and roles in acute stress are established, there is virtually nothing known about their involvement in chronic stress. We intend to determine the effect of modulation of mGluR2/3, mGluR5 and mGluR7 on physiological and behavioural consequences of chronic psychosocial stress in mammals!
  • Over the past two decades we have discovered novel drugs acting on mGluRs, such as PPG, CPCCOEt, MPEP, AMN082, and PHCCC (see publication references below). Over the next years, we intend to increase our knowledge about the exact molecular mechanisms and sites of action of these and related mGluR drugs!
