The Universitat de Barcelona (UB) is Spain's largest university and a preeminent center for neuroscience and neurodegenerative disease research in Catalonia and the broader Mediterranean region. Founded in 1450, it is one of the oldest universities in Spain and has evolved into a modern research institution with exceptional programs in basic science and clinical research. The university serves approximately 64,000 students and houses more than 5,000 researchers across its various faculties and institutes.
The university's research in neurodegenerative diseases spans the full translational spectrum, from fundamental molecular and cellular studies through clinical trials of novel therapeutic interventions. UB researchers have made significant contributions to understanding Alzheimer's disease, Parkinson's disease, and related disorders, with particular strength in studying the Mediterranean population's unique genetic and environmental risk factor profiles. The institution's position in Barcelona provides natural connections to leading European research networks and access to diverse patient populations for clinical studies.
The combination of excellence in molecular biology, cellular neuroscience, and clinical neurology positions UB as a leading institution in the global effort to understand and combat neurodegenerative diseases. Researchers at UB contribute significantly to the European neuroscience community through active participation in international consortia, clinical trials, and basic science collaborations with institutions worldwide.
The Universitat de Barcelona traces its origins to 1450, making it one of the oldest universities in Spain and among the oldest in Europe. The institution was founded during the reign of King Alfonso V of Aragon and has operated continuously for over five centuries. Throughout its history, UB has evolved from a medieval center of learning into one of Spain's premier research universities.
The Faculty of Medicine was established in the 18th century, marking the beginning of UB's formal engagement with medical and health sciences. This establishment laid the foundation for what would become one of Europe's largest medical schools and a major center for clinical research. The Faculty of Biology followed in the 20th century, bringing together researchers focused on understanding the fundamental mechanisms of life at molecular, cellular, and organismal levels.
The Institute of Neuroscience (Institut de Neurociències) was founded more recently to coordinate interdisciplinary research across multiple departments and faculties. This institute serves as the central hub for neuroscience research at UB, bringing together researchers from biology, medicine, psychology, and related disciplines to tackle the complex challenges posed by neurodegenerative diseases. The institute coordinates research programs spanning Alzheimer's disease, Parkinson's disease, multiple sclerosis, and other neurological conditions.
UB's main campus in Barcelona houses the historic building complex, including the Faculty of Medicine, Faculty of Biology, and central research facilities. The university has invested significantly in modern research infrastructure over the past two decades, establishing state-of-the-art facilities for neuroscience research:
The Alzheimer's disease research program at UB represents one of the leading efforts in Spain and Southern Europe. Researchers investigate multiple aspects of the disease, from molecular mechanisms to clinical interventions, with particular focus on the Mediterranean population's unique characteristics.
Amyloid and Tau Pathology
UB researchers have made significant contributions to understanding the molecular mechanisms underlying protein aggregation in Alzheimer's disease. Studies have examined the processes of amyloid-beta production, aggregation, and clearance, as well as tau protein phosphorylation and spread throughout the brain. Research has demonstrated that neuroinflammation plays a critical role in disease progression, with microglial activation and inflammatory cytokine release contributing to neuronal dysfunction and death[@bullón2022].
White matter damage, as revealed by advanced diffusion tensor imaging, has been characterized in Spanish Alzheimer's disease patients, providing insights into the disease's impact on brain connectivity and cognitive function[@agosta2021]. These neuroimaging studies have established important baseline data for early detection and disease monitoring.
Neuroinflammation and Biomarkers
A major focus of UB's Alzheimer's research concerns the role of neuroinflammation in disease progression. Studies have demonstrated that microglial activation, as measured by PET imaging, correlates with disease severity and cognitive decline[@alvarez2022]. This work has important implications for developing anti-inflammatory therapeutic interventions and for using neuroinflammation markers as biomarkers.
Research into blood-based biomarkers has established reference values for Spanish populations, enabling more accurate early detection of Alzheimer's disease[@luna2023]. These studies have demonstrated that Mediterranean populations show characteristic patterns of biomarker abnormalities that differ slightly from Northern European populations, highlighting the importance of population-specific reference values.
Genetic Studies and Risk Factors
Genetic research at UB has focused on identifying risk factors for Alzheimer's disease in the Spanish population. Studies have examined the role of APOE4 carrier status in Spanish cohorts, demonstrating population-specific patterns of genetic risk[@saenz2023]. Research has also investigated novel genetic variants associated with disease risk in Mediterranean populations, contributing to the global understanding of Alzheimer's disease genetics.
The Mediterranean diet's protective effects against cognitive decline have been extensively studied by UB researchers. Longitudinal cohort studies have demonstrated that adherence to Mediterranean dietary patterns is associated with reduced risk of cognitive decline and Alzheimer's disease[@rivera2021]. This work has important implications for preventive strategies and public health recommendations.
Parkinson's disease research at UB encompasses both basic science and clinical investigation, with particular strengths in movement disorders, neuroimaging, and non-motor symptom characterization.
Alpha-Synuclein Biology
Research has focused on understanding the molecular mechanisms of alpha-synuclein aggregation and the formation of Lewy bodies in Parkinson's disease[@calvo2021]. Studies have examined the relationship between alpha-synuclein pathology and clinical symptoms, as well as the mechanisms by which pathological proteins spread throughout the nervous system.
Advanced biomarker studies using real-time quaking-induced conversion (RT-QuIC) technology have been developed for detecting alpha-synuclein aggregates in cerebrospinal fluid, enabling more accurate diagnosis of Parkinson's disease and related disorders[@vilas2022].
Non-Motor Symptoms
A major focus of UB's Parkinson's research has been the characterization and treatment of non-motor symptoms, which are increasingly recognized as important determinants of quality of life. Studies have examined sleep disorders, particularly REM behavior disorder, as early biomarkers of Parkinson's disease[@perez2023]. Research has also addressed autonomic dysfunction, psychiatric symptoms, and cognitive impairment in Parkinson's disease patients.
Genetics and Environmental Factors
The genetic epidemiology of Parkinson's disease in Southern European populations has been characterized through large cohort studies[@ortega2021]. Research has identified novel genetic variants associated with disease risk in Mediterranean populations and has examined the interaction between genetic susceptibility and environmental factors.
UB researchers investigate a broad range of neurodegenerative conditions beyond Alzheimer's and Parkinson's disease:
Motor Neuron Disease and ALS: Research addresses the interplay between genetic susceptibility and environmental factors in Spanish ALS patients, revealing unique patterns of risk factor association.
Tauopathies: Studies examine therapeutic targets in tauopathies, including Alzheimer's disease and other conditions characterized by tau protein pathology[@gomez2023].
