Aberrant proteostasis is thought to be involved in the pathogenesis of neurodegenerative diseases. Some proteostasis abnormalities are ameliorated by chaperones. Chaperones are divided into three groups: molecular, pharmacological and chemical. Chemical chaperones intended to alleviate stress in organelles, such as the endoplasmic reticulum (ER), are now being administered clinically. Of the chemical chaperones, 4-phenylbutyrate (4-PBA) has been used as a research reagent, and its mechanism of action includes chaperone effects and the inhibition of histone deacetylase. Moreover, it also binds to the B-site of SEC24 and regulates COPII-mediated transport from the ER. Although its therapeutic effect may not be strong, elucidating the mechanism of action of 4-PBA may contribute to the identification of novel therapeutic targets for neurodegenerative diseases.

Copyright © 2018 by the American Clinical Neurophysiology Society Purpose: Lateral trunk flexion is often observed in patients with Parkinson disease (PD) and causes poor quality of life. Asymmetrical function of the basal ganglia is believed to be the main cause of lateral trunk flexion, and dysfunction of the basal ganglia facilitates the blink reflex by disinhibiting the spinal trigeminal nucleus. Our aim was to investigate whether a disinhibited blink reflex recovery curve (BRrc) was associated with lateral trunk flexion in PD patients. Methods: We enrolled 21 PD patients, including 11 with marked lateral trunk flexion (F-PD) and 10 with normal posture (N-PD), and 10 normal controls. Blink reflex recovery curves at interstimulus intervals of 200, 300, and 500 ms were compared between F-PD N-PD and normal controls. Results: The BRrc in F-PD patients was more disinhibited than in N-PD patients and controls, and this disinhibition was asymmetrical. Conclusions: The asymmetrically disinhibited BRrc in F-PD patients was associated with lateral trunk flexion. This is the first neurophysiological study of patients with PD with abnormal posture. Examination of the BRrc may permit early detection of asymmetrical basal ganglia dysfunction that can eventually cause lateral trunk flexion.
