Nykjær Group - Receptor Biology


Using transgenic animal models the Nykjær group is studying sortilin receptors in memory, trans-synaptic communication and signaling.

Research focus

Research activities are focused towards the functional characterization of a family of neuronal type-1 receptors denoted sortilins, comprising sortilin, SorLA, and SorCS-1, -2, and -3 with particular emphasis on their role in memory formation and recall, and in emotional regulation. Sortilins bind a vast number of ligands including neurotrophic factors, synaptic proteins, Alzheimer precursor protein (APP), and progranulin implying critical roles in regulation of neuronal survival, differentiation and integrity, and in synaptic plasticity. Indeed, a number of genetic association studies and gene targeting in mice have linked dysfunction of the sortilin receptors with neuropsychiatric and degenerative diseases including ADHD, schizophrenia, bipolar disorder, Alzheimer’s Disease, and frontotemporal lobar dementia.

Using transgenic mouse models, a broad repertoire of molecular, cellular and genetic tools, electrophysiology, mouse behavior, and confocal and two-photon microscopy it is our goal to unravel the function of the receptor family in health and disease and to evaluate their potential as drug targets.  

Available projects

The Nykjær group currently has projects available for Master students and postdocs within the following research areas.

Functions of the sortilin receptor family in health and disease:

  • Synaptic plasticity, memory, and psychiatric disorders
  • Functionality of the dopaminergic system

Congratulations to Pernille Bogetofte Thomasen who has started as a postdoctoral researcher in Anders Nykjær’s group from September 1st

In Nykjærs group she will continue the work from her PhD project. Pernille is investigating the function of SorCS2 in motor neuron development and regeneration by combining cell biological experiments with in vivo studies in zebrafish and mice. The findings can provide important information about mechanisms underlying neuronal wiring but also…
