Chyi's review on intracellular thermometry probes and their application to study thermodynamic properties of cells and energy flow in protein aggregation is published in ChemBioChem and featured as the technology of the month in Trends in Biochemical Sciences.
We highlight different nanoscale thermoprobes that have enabled intracellular temperature gradients to be visualised. Intracellular thermometry is proposed as a tool to quantify energetics involved in amyloid-beta 42 aggregation, a hallmark of Alzheimers' disease.

A new mechanism on how endoplasmic reticulum reshapes is revealed by a combinatorial method of super-resolution imaging, optogenetic tools and machine-learning from LAG-MNG:
The endoplasmic reticulum (ER) is dynamically regulated by lysosomes by VAPA dependent membrane contacts.
In neuronal axons, lysosomes drive ER tubules to move along axons thus connect ER fragments to be a continuous membrane structure.

Our new publication 'Purification of Recombinant α-synuclein: A Comparison of Commonly Used Protocols'shows our choice of purification method for a-syn influences the outcome of downstream assays
We therefore wonder whether the choice of purification method e.g. 'harsh' treatments such as boiling, can influence the dynamic ensemble of the monomeric protein, changing the conformational distribution, and influence downstream assays, such as cell response or aggregation rate.

A new paper on Αβ purification led by Amberley Stephens is out now.
We provide a method for the purification of recombinant label-free amyloid-β using commercially available reagents and without the need for a freeze drying step which induces oligomerisation.

We are very excited to share our latest research published in Nature Communications on alpha-synuclein conformational dynamics!
We investigated the monomeric conformation of aSyn in different conditions and found that the more exposed the N-terminus of the protein becomes, the more aggregation-prone it becomes.
Sequence alterations such as the presence of post-translational modifications and familial point mutations that lead to early-onset Parkinson's disease also lead to differing exposure of the N-terminus, linked to aggregation propensity.
This paper is led by Amberley Stephens and Maria Zacharopoulou and is a result of a big collaboration cohort. Many congratulations to all!

Monomeric amyloid-β is notoriously challenging to purify. Fear not, as the new preprint led by Amberley Stephens is now on bioRxiv.
We provide a protocol to purify monomeric recombinant Abeta in 3 hours using a one-step chromatography approach.

Our new article sheds light on the coupling between mitochondrial impairment and α-synuclein pathology!
We show that protein homeostasis in mitochondria plays a major role in α-synuclein aggregation, as a disruption of intramitochondrial proteases leads to aggravated α-synuclein seeding.
The paper is led by Janin Lautenshläger, and includes work performed by many LAG and MNG members. Many congratulations to all!

The article introduces a new method based on fluorescence lifetime to measure chromatin compaction in any cell, live or fixed, without genetic modification. It is a result of the collaboration between members of the Laser Analytics Group and the Molecular Neuroscience Group. Many congratulations to all who contributed!

Ioanna Mela's article on DNA-origami as an antimicrobial delivery agent is published in Angewandte Chemie.
The paper is led by the Laser Analytics Group's postdoc Ioanna Mela and includes collaborations with MNG.
Many congratulations to authors: Ioanna Mela, Pedro Vallejo-Ramirez, Stanislaw Makarchuk and Clemens Kaminski!

Despite the national quarantine we continue our work remotely - more new exciting projects on the way!
Congratulations to our authors of the recent paper "Structural progression of amyloid-β Arctic mutant aggregation in cells revealed by multi-parametric imaging.”!
The article was selected for the 2019 retrospective collection called “The year in JBC: 2019.” The associate editors looked through hundreds of papers to come up with what they felt best represented the exciting advances reported in JBC last year. The issue can be found here.
