Neuronal and glial cell alterations involved in the retinal degeneration of the familial dysautonomia optic neuropathy.

Familial dysautonomia (FD) is a rare genetic neurodevelopmental and neurodegenerative disorder. In addition to the autonomic and peripheral sensory neuropathies that challenge patient survival, one of the most debilitating symptoms affecting patients' quality of life is progressive blindness resulting from the steady loss of retinal ganglion cells (RGCs). Within the FD community, there is a concerted effort to develop treatments to prevent the loss of RGCs.

Holistic in silico developability assessment of novel classes of small proteins using publicly available sequence-based predictors.

The development of novel therapeutic proteins is a lengthy and costly process, with an average attrition rate of 91% (Thomas et al. Clinical Development Success Rates and Contributing Factors 2011-2020, 2021). To increase the probability of success and ensure robust drug supply beyond approval, it is essential to assess the developability profile of new potential drug candidates as early and broadly as possible in development (Jain et al.

, the Gene Mutated in Familial Dysautonomia, Is Required for Normal Enteric Nervous System Development and Maintenance and for Gut Epithelium Homeostasis.

Familial dysautonomia (FD) is a rare sensory and autonomic neuropathy that results from a mutation in the gene. Virtually all patients report gastrointestinal (GI) dysfunction and we have recently shown that FD patients have a dysbiotic gut microbiome and altered metabolome. These findings were recapitulated in an FD mouse model and moreover, the FD mice had reduced intestinal motility, as did patients.

Pain in Multiple System Atrophy: A Community-Based Survey.

Background: Pain is a frequent yet poorly characterized symptom of multiple system atrophy (MSA). Understanding the factors influencing pain and its burden is crucial for improving the symptomatic treatment and quality of life of MSA individuals.

Objective: This study aimed at assessing the prevalence, characteristics, and current treatment strategies for pain in MSA.
