Jensen Group

Jensen Group - Neurodegenerative Disease Laboratory

Our group is interested in understanding how alpha-synuclein contributes to the neurodegenerative processes in Parkinson’s disease, Lewy body dementia and multiple systems atrophy, which are hallmarked by the development of intracellular aggregates of alpha-synuclein. This is investigated in studies of alpha-synuclein aggregates in vitro, in cell models, transgenic animals and human tissue and involves development of new aggregate selective tools.

Research focus

The aim is to decipher how cells regulate their pools of alpha-synuclein species and how they respond to misfolded alpha-synuclein with respect to cytotoxic and protective mechanisms that can be targeted by therapy. This involves proteostatic mechanisms like autophagy, unconventional secretion, prion-like intercellular propagation and homeostatic cellular mechanisms being offset by alpha-synuclein aggregates.

Currently specific projects focuses on alpha-synucleins role in calcium regulation, kinase pathways regulating alpha-synuclein turn-over and toxicity, relation to the innate immune system and implementation of a mouse model for prion-like spreading of alpha-synuclein brain pathology.

Available projects

The Jensen group currently has projects available for Master and PhD students. Please contact Group Leader Poul Henning Jensen directly, if interested.

Hjalte Gram is new masterstudent in Jensen Group

Hjalte is new masterstudent in Poul Henning Jensen's group from August 15th. He is going to study  gene expression related to the Calcium changes that are induced by intracellular alpha-synuclein aggregation. The aim is to characterise pathogenic pathways induced by aggretade alpha-synuclein.

Polo-like kinase 2 (PLK-2) phosphorylates an unknown target, which leads to regulation of α-synuclein mRNA by targeting exonal sequences in the gene encoding α-synuclein, SNCA. PLK-2, and other kinases, additionally phosphorylates α-synuclein, which might be involved in the misfolding of the protein and development of toxic protein species such as oligomers and fibrils.

Emil Gregersen is new PhD student in Jensen Group

Emil Gregersen started as a PhD student in Poul Henning Jensen's group per March 1st 2017. Emil will work with the endoplasmic reticulum anchored deubiquitinase USP19 which has a key role in targeting misfolded proteins including α-syn for secretion under proteasomal stress. Preliminary data suggest aggregated α-syn as a target of USP19 and this…
