Chemical Proteomic Analysis of Serine Hydrolase Activity in Niemann-Pick Type C Mouse Brain

2018

The endocannabinoid system (ECS) is considered to be an endogenous protective system in various neurodegenerative diseases. Niemann-Pick type C (NPC) is a neurodegenerative disease in which the role of the ECS has not been studied yet. Most of the endocannabinoid enzymes are serine hydrolases, which can be studied using activity-based protein profiling (ABPP). Here, we report the serine hydrolase activity in brain proteomes of a NPC mouse model as measured by ABPP. Two ABPP methods are used: a gel-based method and a chemical proteomics method. The activities of the following endocannabinoid enzymes were quantified: diacylglycerol lipase (DAGL) α, α/β-hydrolase domain-containing protein 4, α…

Current state of clinical and morphological features in human NCL.

2004

The neuronal ceroid lipofuscinoses (NCL) are large group of autosomal recessive lysosomal storage disorders with both enzymatic deficiency and structural protein dysfunction. Previously, diagnosis of (NCL) was based on age at onset clinicopathological (C‐P) findings described 4 forms, classified as infantile (INCL) (2), late‐infantile (LINCL) (5), juvenile (JNCL) (6), and adult (ANCL) most patients with NCL have progressive ocular and cerebral dysfunvtion, including cognitive/motor dysfunction and uncontrolled seizures. After reviewing 520 patients with NCL, we found that about 104 (20%) did not fit this classification of NCL With further research, 4 additional forms have been recognized: F…

Dementia in the Neuronal Ceroidlipofuscinoses

2001

Dementia is defined as a decline in cognitive abilities such as impairment of memory, reasoning, behaviour, attention, motivation and effectiveness. The term usually implies that normal mature mental capability was achieved before, and it is therefore mostly ascribed to adult patients.
