Active NCL Network


Collaborations initiated by the NCL Foundation

 

Since its establishment in 2002, the NCL Foundation attempts to close research gaps through targeted start-up financing. Scientific meetings with focus on changing topics are organized by the NCL Foundation. They account to indirect measures with the goal to improve the research networking. These events are used as platform to exchange results as well as innovative research ideas and as basis for new collaborations. The arising research projects are partially supported with start-up funds in form of Ph.D. scholarships.

 

Moreover, the NCL Foundation directly links research groups on a one-to-one basis. The current intermediate results (August 2013) show that the NCL Foundation was able to launch around 40 new research collaborations since 2002. The majority of the newly established cooperations are university groups (66 %). Collaborations between university groups and research institutes or researching companies, respectively, each account for 17 %. 

 

The exchange with other non-profit NCL organizations as well as training programs for doctors, students, and pupils are further indirect measures to improve the research networking.

Dr. Susan L. Cotman (Homepage)

 

Dr. Cotman is a partner in the Community program NCL disease, a clinical and translational research program within the Center for Human Genetic Research at the Massachusetts General Hospital. The Cotman laboratory specializes in genetic and cell biological research and its goal is to describe the first occurrences which are caused by a genetic defect NCL. Exact genetic models were established for early detection as well as for drug screening and for pre-clinical drug development. Among developed NCL models there are both the Cln3ex7/8-mice, which will carry the common mutation described in NCL patients and now in widespread use, as well as newer model systems, such as human induced pluripotent stem cells (iPS cells) for several NCL forms.

 


Prof. Dr. Ronald G. Crystal (Homepage)

 

Dr. Crystal is a professor in the department of genetic medicine at Weill Medical College of Cornell University in New York. His research focuses on gene therapy and personalized medicine. The development of therapies for paediatric neurodegenerative diseases, particularly lysosomal metabolic diseases, is one of its biggest areas of research. Using the late-infantile NCL (caused by mutations in the CLN2 gene as a model, his lab was able to develop a strategy for the treatment of CNS manifestations in these diseases). Studies with multiple animal models have supported the initiation of clinical trials with NCL patients.

 


Prof. Dr. Beverly L. Davidson (Homepage)


The Davidson laboratory in Iowa, USA showed that CLN3 is a lysosomal membrane protein and also how mutations within CLN3 alter protein trafficking and function. Using in vitro transcription and translation experiments, we have begun to unravel how the protein orientates itself within the lysosomal membrane. Additional experiments are underway to test if CLN3 associates with other lysosomal or non-lysosomal proteins. With the CLN3 animal model in hand, we are also determining if gene transfer of CLN3 to the brain restores neuron survival. The ultimate goal is to understand how an absence of CLN3 leads to neurodegeneration, and to test if gene replacement imparts protection to the degenerative phenotype.

They are currently investigating several lysosomal transporters at various levels. 

 


Prof. Dr. Jeffrey Gerst (Homepage)

 

His group is studying the mechanisms of endosomal protein sorting and delivery to the vacuole/lysosome in Rehovot, Israel. In particular, they use yeast as a model for Batten Disease, a severe neurodegenerative disorder that results from the aberrant accumulation of material in lysosomes. Their work suggests that mutations in the yeast orthologs of human Batten disease genes have specific defects in intracellular protein trafficking. Thus, yeast can serve as a simple tool to understand how Batten disease and related human lysosomal storage disorders occur.

Three different mouse models for CLN1, CLNf3 and CLN6 are now being investigated with regard to visual acuity using non-invasive optokinetic and electrophysiological tests. These parameters are combined with comprehensive histological studies to estimate the effect of microgliosia and Müller cell gliosis on the development of retinal degeneration in NCL models.

 


Dr. Stephane Lefrancois (Homepage)

 

Dr. Lefrancois’ reserach is of the regulation of intracellular sorting and transport processes with a focus on the monitoring of the sorting through the trans-Golgi network and endsomes. The model they study is the lysome sorting receptor CI-MPR and Sortilin. Recently they discovered that CLN5 is a key regulator in the intracellular sorting via the endosome. Right now they are working on understanding the molecular details of how CLN5 monitors the activity of the small GTPase Rab7 and the recruitment of retromer, a protein complex that is used for sorting the endosome to Golgi from CI-MPR and Sortilin.

 

The laboratory uses a number of techniques such as acquisition and analysis of images with high image content, confocal microscopy, BRET (“bioluminescence resonance energy transfer“) and various ways to study post-translational modifications such as palmitoylation and ubiquitination.

Dr. Mika O. Ruonala (Homepage)

 

By combining novel methods of biochemistry, molecular biology and biophysics we aim to the discovery of the function of the CLN3 protein at its physiological state. Using novel tagging technologies we have generated reliable imaging tools which allow us to investigate the localization, properties and lifetime of CLN3 in living cells and tissues. These tools are also applicable for biochemical determination of the interaction partners of CLN3 in combination with mass-spectrometry, and the location of the found interacting partners are verified with state-of-the-art FRET-FLIM microscopy. Once we have a good understanding about the function of the CLN3 we will apply similar approaches to investigate the properties and behaviour of the diseased form of the CLN3. A recently initiated project aims to determine the changes in the molecular networks in the JNCL mouse model. This novel imaging technology is able to resolve the amount and localization of any given number of proteins in the same tissue or cell sample with high accuracy. Using the toponomics approach the abnormal behaviour of 'lead' protein, lipid or carbohydrate components will be exposed and will reflect the initial changes in the proteomic landscape that eventually lead to the acceleration of the JNCL. The generated information can be used to guide the design and monitoring of the effects of future therapeutic approaches.
