neuroserpin

neu·ro·ser·pin

(nūr-ō-sĕr-pin),
Axonally released neuronal serine protease inhibitor found in cortical and hippocampal neurons; a familial form of presenile dementia has been linked to mutations of neuroserpins; mutant neuroserpins form polymers or inclusion bodies result in neuronal degeneration

SERPINI1

A gene on chromosome 3q26.1 that encodes a member of the serpin superfamily of serine proteinase inhibitors that inhibits tissue-type plasminogen activator. It is secreted by axons in the brain and thought to play a role in regulating axonal growth and the development of synaptic plasticity or the reorganisation of synaptic connections. SERPINI1 may protect neurons from cell damage by tissue-type plasminogen activator.

Molecular pathology
SERPINI1 mutations cause familial encephalopathy with neuroserpin inclusion bodies (FENIB), an autosomal dominant form of familial encephalopathy and epilepsy.

Zygin, neuroserpin, and GAD67 were below the limit of detection of this method (<2.5 [micro]g/L), and the intensity of the VLP-1 band was between the 25 and 250 [micro]g/L VLP-1 standards.
