Nykjær Group

Receptor Neurobiology

Research activities are focused towards the functional characterization of a group of type-1 receptors denoted the Vps10p-domain family, or so-called sortlins, that comprises sortilin, SorLA, and SorCS-1, -2, and -3. The receptors are enriched in neurons where they mediate trafficking and signaling of a vast number of ligands such as neurotrophic factors along with their cognate receptors, neurotransmitter receptors, APP, and progranulin. Among many activities, the receptors regulate neuronal cell fate, differentiation, innervation, synaptic plasticity, and learning and memory. Key goals of the Nykjaer lab is to understand their functions in the heathy brain, dissect out their mode of actions, investigate how genetic variation contributes to disease development - in particular of neuropsychiatric disorders and memory impairment -, and to evaluate their potential as drug targets.

Methodologies include transgenic mice and zebrafish, a broad repertoire of molecular, cellular and genetic and viral tools, transcriptomics and (phospho)proteomics, neuroembryology, mouse behavior, electrophysiology and advanced imaging including high-resolution microscopy. In vivo fiber photometry and mesoscale single unit recordings are currently being implemented.

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:

  • Molecular mechanisms underlying memory and psychiatric disorders

New publication from Anders Nykjær's group - SorCS2 is required for BDNF-dependent plasticity in the hippocampus

SorCS2 is a member of the Vps10p-domain receptor gene family receptors with critical roles in the control of neuronal viability and function. Several genetic studies have suggested SORCS2 to confer risk of bipolar disorder, schizophrenia and attention deficit-hyperactivity disorder. Here we report that hippocampal N-methyl-d-aspartate…

New publication from Anders Nykjær's group - The proneurotrophin receptor sortilin is required for Mycobacterium tuberculosis control by macrophages

Sorting of luminal and membrane proteins into phagosomes is critical for the immune function of this organelle. However, little is known about the mechanisms that contribute to the spatiotemporal regulation of this process. Here, we investigated the role of the proneurotrophin receptor sortilin during phagosome maturation and mycobacterial…

New publication from Anders Nykjær's group - Sortilin mediates vascular calcification via its recruitment into extracellular vesicles

Vascular calcification is a common feature of major cardiovascular diseases. Extracellular vesicles participate in the formation of microcalcifications that are implicated in atherosclerotic plaque rupture; however, the mechanisms that regulate formation of calcifying extracellular vesicles remain obscure. Here, we have demonstrated that sortilin…

Growing pains in the brain's reward system can lead to ADHD

New research from Anders Nykjær's group at Aarhus University and one of the world's leading hospitals contributes to the understanding of ADHD. Experiments on mice show how the incorrect branching of nerve cells in the brain’s reward system leads to behavioural disorders.

New publication from DANDRITE researchers - new way for cholesterol treatment

Researchers from Anders Nykjær's group publish new results on cholesterol research in the article "The Hypercholesterolemia-Risk Gene SORT1 Facilitates PCSK9 Secretion" published in Journal of Cell Metabolism. The results show that there is apparently another and just as effective way of reducing so-called bad cholesterol, which is the cause of…
