New proteins involved in Spinocerebellar Ataxia provide insight into selective neuronal vulnerability

1/10/23

Neurodegenerative disorders like Alzheimer’s and Parkinson’s disease result from the loss of specific types of neurons due to abnormal accumulation of mutant proteins. Although specific brain regions have been found to be particularly vulnerable in each of these disorders, intriguingly, the disease-driving genes and the proteins they encode are usually broadly expressed and are known to function throughout the brain.

New tau regulators and therapeutic targets for neurodegenerative disorders discovered

1/10/23

Neurodegenerative diseases affect millions of people worldwide and as our life expectancy increases, more individuals are expected to be affected in the coming decades. Tauopathies such as Alzheimer’s disease are a class of neurodegenerative disorders involving a pathological accumulation of tau proteins which eventually results in massive loss of brain cells.

A new neurodevelopmental epilepsy disorder and its genetic cause discovered

12/16/22

Neurodevelopmental disorders (NDD) encompass highly prevalent conditions such as autism and epilepsy, with cognitive disabilities alone affecting 1-3% of the global population. Developmental epileptic encephalopathies (DEE) are NDD characterized by epilepsy and delayed development or loss of developmental skills. Although the prevalence of DEEs remains to be determined, studies estimate that single-gene epilepsies occur in around 1 in 2100 births annually.

Oxytocin drives development of neural connections in adult-born neurons

12/13/22

Learning a new task, mastering a musical instrument or being able to adapt to the constantly changing environment are all possible thanks to the brain’s plasticity, or its ability to modify itself by rearranging existing neural networks and forming new ones to acquire new functional properties. This also helps neural circuits to remain healthy, robust and stable.

An animal model of West syndrome exhibits a progressive increase in epileptic spasms and learning and memory deficits

11/2/22
The Swann lab provides the first demonstration of a progressive increase in seizure duration along with a decline in learning and memory in the tetrodotoxin-induced model of infantile spasm.

11/2/22
The study reveals an extraordinary and an unprecedented mechanism for synaptic plasticity.

Spontaneously arising variants in FRMD5 gene are associated with a novel neurological disease

10/7/22
Researchers in the Bellen lab discover a new neurological disorder.

Researchers discover 50 novel Parkinson's disease candidate genes using an innovative multilayered approach

10/3/22
Jianyang Li and others in the Botas lab use an integrated functional genomics approach to find 50 new genes involved in Parkinson's disease.

Disruption of MTSS2 function causes a new syndromic intellectual disability

9/27/22
The Bellen lab discovers that a spontaneous mutation in MTSS2 gene is the underlying cause of a new syndromic intellectual disability.

A comprehensive clinical study confirms the molecular link between microcephaly caused by Zika and ANKLE2 variants

9/13/22
In a first-of-its-kind study, an international team of researchers report a comprehensive phenotypic and genotypic analysis of the largest cohort to date of patients with ANKLE2 gene variants, which were identified a few years ago as the cause of microcephaly (‘abnormally small head’) in infants.

Duncan NRI team develops an award-winning new computational tool to study movement disorders

9/8/22
The Duncan NRI team plan to use the Poly(A)Miner-Bulk tool to create a signature APA pattern for XDP, which can then be used to develop specific and effective diagnostic and treatment options for XDP patients. They are hopeful that if successful, this strategy can then be replicated for those with Parkinson’s disease and different forms of dystonia. 

Researchers discover novel light-gated potassium channel

7/20/22
The Xue lab and collaborators find a new class of light-gated channels that promise to pave the way for rapid and efficient optical neuronal silencing.  

Disruptions in brain sphingolipid metabolism reveal new insights into cause of Gaucher disease

7/14/22
A study by Bellen lab researchers is the first to associate neuronal activity to the levels of sphingolipids, a type of fat, in brain cells.

A pioneering study discovers an underlying cause for infantile spasms and points to a novel therapy

5/11/22
An exciting new study by Dr. Carlos Ballester-Rosado and others in the Swann lab finds an underlying cause and a potential new therapy for infantile spasms.

Texas Children’s Hospital and Baylor College of Medicine study opens the door to improved diagnosis, prognosis and potential therapies for EBF3 and other neurodevelopmental disorders

4/20/22
Dr. Chao and her team have discovered that patients with EBF3 gene variants affecting a critical region — zinc finger domain (ZNF) of the encoded transcription factor protein — suffer from a more severe subtype of EBF3-related neurodevelopmental disorders and other autism spectrum disorders.
