Researchers surprised by similar structures in Sanfilippo syndrome and Alzheimer's disease

06.05.2009
Rare genetic disorder may benefit from development of new dementia treatments

Researchers seeking to understand the causes of a rare genetic lysosomal storage disease, Sanfilippo syndrome type B, were surprised to find protein aggregates, known as neurofibrillary tangles, that are usually seen in Alzheimer's and other forms of dementia, according to a study published May 4 in the Proceedings of the National Academy of Sciences.

The discovery, in a study conducted at the Los Angeles Biomedical Research Institute (LA BioMed) and the University of California, Los Angeles (UCLA), means that the childhood dementia often seen in lysosomal storage diseases may have mechanisms similar to those found in Alzheimer's disease and other age-related dementias, which are characterized by an abnormal accumulation of the protein, P-tau.

The scientists also said these findings mean those suffering from these rare disorders could one day benefit from the abundance of research underway for the growing numbers of Alzheimer's patients.

"We were trying to determine what in the cellular environment makes certain brain regions more vulnerable to neurodegeneration, and we were surprised to find the presence of a protein, P-tau, and the corresponding aggregates similar to neurofibrillary tangles we see in Alzheimer's patients," said Stanislav L. Karsten, PhD, a corresponding author of the study and a LA BioMed investigator. "With the increasing incidence of Alzheimer's disease, we expect to see new drugs developed to prevent these neurofibrillary tangles or dissolve them. Our findings suggest those treatments could also benefit patients with this rare genetic disorder, Sanfilippo syndrome."

Sanfilippo syndrome, also known as MPS III, occurs in approximately one in 70,000 births, causing profound mental retardation, behavior problems and, frequently, death before the age of 20. It is one of nearly 40 lysosomal storage diseases caused by the body's inability to produce enzymes that break down and recycle materials in cells. Without the enzymes, materials are stored in virtually every cell of the body, causing severe damage over time. There is no treatment for Sanfilippo syndrome.

Alzheimer's disease affects 2 million to 4 million Americans, and their ranks are expected to grow to as many as 14 million by the middle of the 21st century as the population ages.

Grants from the National Institutes of Health, the Children's Medical Research Foundation, the National Alliance for Research on Schizophrenia and Depression and the Alzheimer's Association funded this research.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
