Research summary

Currently, neurodegenerative diseases are attracting the interest of the scientific community due to the dramatic increase in the number of cases and their impact on public health. Many of these diseases, such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and prion diseases, share common features and molecular patterns including protein misfolding, protein aggregation, and cell death. There is an unrevealed understanding on the specific mechanisms of how these aggregation process starts, and how they are implicated with complex pathways to trigger finally toxicity and neuronal loss. Prion research has been utilized to reveal details of protein misfolding disorders expanding the possibility to develop an early diagnostic method and future treatments for prions disease and to other protein misfolded disorders.

Current research interests

Dr Barria research interests lie in the field of neurodegenerative disorders, and for the last two decades He has been investigating the molecular pathology of prion diseases using tissue-base approaches, and animal and in vitro models. Prion diseases are associated with the conformational change of a normal protein, termed the prion protein, to a misfolded isoform. They can affect both animals and humans, and they are transmissible and fatal. Dr Barria current research interests are to explore (i) the molecular basis of human and animal prion diseases and their potential for zoonotic transmission; (ii) the effect of cofactors which may influence prion conversion; (iii) the events that trigger their spontaneous formation; and (iv) developing of highly sensitive molecular tools for the early diagnosis of neurodegenerative illnesses.
