Langenhan Lab

​​We focus on two research fields: Adhesion G protein-coupled receptors ​and Molecular processes of synaptic transmission.

Several of our research activities are embedded in the CRC 1423 "Structural dynamics of GPCR activation and signaling", the Graduate school "Brain Dynamics" and the Comprehensive Cancer Center Central Germany.

Adhesion G protein-coupled receptors

We are dedicated to solve important questions regarding this outstanding yet insufficiently understood receptor family:

  • Which stimuli activate adhesion GPCRs?
  • Which effects on cells, tissues and organs are controlled through adhesion GPCRs?
  • How do defective adhesion GPCR signals contribute to human diseases (neuropsychiatric conditions, immune diseases, cancers)?​

Molecular processes of synaptic transmission

We investigate the action of genes and proteins that partake in synaptic transmission and information processing:

  • How do synaptic proteins interact at such small local (in the sub-nanometer range) and temporal (in the millisecond range) scales?
  • How does disease arise from defective molecular components of the synaptic machinery?


Adhesion G protein-coupled receptors

  • Enzymology of autoproteolysis and signaling function of the GAIN domain in adhesion GPCRs (supported through CRC 1423; collaboration with Prof. N. Sträter)
  • Dynamic modulation of adhesion GPCR function through complex formation (supported through CRC 1423; collaboration with Dr. N. Scholz)
  • Functional analysis of the adhesion GPCR class in Drosophila (previously supported through FOR 2149; collaboration with Dr. N. Scholz)
  • Interaction of adhesion GPCR signalling and ionotropic pathways during mechano-sensory signal transduction (previously supported through FOR 2149; collaboration with Prof. R.J. Kittel)
  • FRET-based monitoring of Adhesion class G protein-coupled receptor activity (previously supported through CRC-TRR 166)
  • Physiology and pathophysiology of mechanoceptive signalling pathways
  • Disease models for neuropsychiatric conditions, immune system ailments and cancers
  • Molecular processes of synaptic transmission
  • Molecular control of the synaptic cleft dimensions
  • Diseases models for neuropsychiatric conditions
