Myelin loss in C9orf72 hexanucleotide expansion carriers

Myelin loss in C9orf72 hexanucleotide expansion carriers   The expansion of the intronic GGGGCC repeat (G4C2) in the C9orf72 gene is the most common genetic cause of Frontotemporal Dementia (FTD), Amyotrophic Lateral Sclerosis (ALS) and in the continuum of FTD/ALS. Three pathological mechanisms associated with the presence of this genetic alteration have been described: a … Read more

The link between Alzheimer’s disease and Down syndrome

Association of Alzheimer Disease With Life Expectancy in People With Down Syndrome

The link between Alzheimer’s disease and Down syndrome People with Down syndrome are genetically predisposed to developing Alzheimer´s disease. The strong association between Alzheimer disease and Down syndrome has a genetic basis through a gene-dose effect of the amyloid precursor protein (APP) gene located on chromosome 21, which is triplicated in this population. Consequently, neuropathologic changes associated with … Read more

Characterization of the transcriptome of the motor cortex in amyotrophic lateral sclerosis

Transcriptoma - ELA - Sant Pau Memory Unit - Barcelona

What is the transcriptome and why the motor cortex? The transcriptome is a set of tens of thousands of molecules called RNAs that have a key role in the formation of proteins and, therefore, in the response to pathological processes in the body. On the other hand, the motor cortex is the region of the … Read more

Circular RNAs in Alzheimer and frontotemporal dementia

Circular RNAs in Alzheimer and frontotemporal - Cervera - Sant Pau Memory Unit

What are circular RNAs? RNAs are a type of molecules present in all human cells. They usually have a linear conformation. However, some species with a ring-like structure have recently been described and named “circular RNAs”, but little is known about their function. Recent studies in the field have reported changes in the levels of … Read more

Now available our review on genetics in neurodegenerative dementias

Genetics - Clarimon - Sant Pau Memory Unit

Although there are other unmodifiable causes of dementia, the existence of family aggregation indicates that genetics play a role to a greater or lesser extent. In recent years, there have been numerous studies that have provided new information that helps to better understand the genetic component in neurodegenerative diseases. Our Research Group, together with researchers … Read more
