GCH1 gene and Parkinson's risk

A study published in Brain, led by researchers at UCL Institute of Neurology, has shown that genetic mutations which cause a decrease in dopamine production in the brain and lead to a form of childhood-onset Dystonia, also play a role in the development of Parkinson’s disease.

Audioslide presentation on Claudia Manzoni's paper examining how fibroblasts with LRRK2 mutations react to starvation conditions and the possible deficits that they have in autophagy.

LRRK2 and autophagy in fibroblasts

In this paper Claudia Manzoni studies how fibroblast cells from people with Parkinson’s disease caused by mutations in LRRK2 react to starvation. Although the changes are quite subtle, there are differences between the way that fibroblasts that contain mutant LRRK2 respond to being starved – suggesting that there may be changes in the way that these cells regulate a key process called autophagy (a term which comes from the greek meaning to eat yourself, and is one of the ways that cells get rid of waste and recycle proteins and organellles).

Genetic mutations linked to Parkinson's disease

Research led by consortium researchers Dr Helene Plun-Favreau (UCL Institute of Neurology) and Dr Alex Whitworth (University of Sheffield), and collaborator Dr Heike Laman (University of Cambridge), has discovered how genetic mutations linked to Parkinson’s disease might play a key role in the death of brain cells, potentially paving the way for the development of more effective drug treatments. In the new study, published in Nature Neuroscience, the team of cross-institutional researchers showed how defects in the Parkinson’s gene Fbxo7 cause problems with mitophagy. More...

LRRK2 and autophagy

Mutations in LRRK2 are the most common genetic cause of Parkinson’s disease. Here, Claudia Manzoni talks about her research (funded by the Rosetrees Trust and the Michael J. Fox Foundation) into what LRRK2 might be doing within the cell: Parkinson’s disease is a brain illness that afflicts 1 in 500 people in the UK. High profile patients, such as the actor Michael J Fox, the boxer Muhammad Ali and the late Pope John Paul II, have raised public awareness of Parkinson’s and its devastating impact. More...

Adamantios Mamais


I hold a multi-disciplinary research background having had the opportunity to study and investigate many aspects of cell biology leading to human disease. Having completed a BSc in Molecular Biology at University College London in 2001, I pursued an MSc in Molecular Medicine, at the same university, that equipped me with a deeper understanding of the underlying mechanisms and consequences that give rise to pathology, when the blue-prints of nature go wrong.

My academic studies cultivated my enthusiasm on the molecular events of human disease, while I had the chance to work on proteins involved in gastrulation and synaptic neurotransmission, and also tumour targeting drugs, during my BSc/MSc research projects respectively. During a summer placement at the UCL Institute of Neurology I was involved in a project investigating the mechanistics of filopodia formation in developing neurons. I then joined the Institute of Cancer Research for two years as a Scientific Officer to investigate nucleosomal positioning and chromatin remodelling mechanisms in V(D)J recombination. In 2005 I focused my research skills and experience in pursuing a PhD at the UCL Institute of Neurology, in the lab of Prof Louis Lim and Dr Christine Hall, investigating novel mechanisms of interplay between cytoskeletal remodelling factors involved in neuronal differentiation and mRNA binding factors involved in local translation in axons and formation of Stress Granules.

In 2010, I joined the team of Dr Rina Bandopadhyay and Dr Patrick Lewis at the Reta Lila Weston Institute, UCL Institute of Neurology, as a post-doc Research Associate, and I am currently investigating the molecular events that underlie LRRK2 associated Parkinson’s disease. My research utilises the invaluable resource of post-mortem human brain tissue from Parkinson’s cases, provided by the Queen Square Brain Bank. We are focusing on the post-translational modifications and neuropathological features of two LRRK2 putative partners in disease, a-Synuclein and 4E-BP1. Furthermore, I have initiated a novel project investigating the role of mutated LRRK2 in mRNA Stress Granule formation, recently involved in pathologic protein aggregation in neurodegenerative diseases.
