DeCure for Familial encephalopathy with neuroserpin inclusion bodies
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for familial encephalopathy with neuroserpin inclusion bodies — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.
Disease moduleFamilial encephalopathy with neuroserpin inclusion bodies maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead
No approved-drug candidate for familial encephalopathy with neuroserpin inclusion bodies is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.
Molecular view
serpin family I member 1 (SERPINI1) — SERPINI1 is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

Encephalopathy with Neuroserpin Inclusion Bodies Presenting as Progressive Myoclonus Epilepsy and Associated with a Novel Mutation in the <i>Proteinase Inhibitor 12</i> Gene
AbstractNeuroserpin encephalopathy is an autosomal-dominant degenerative disease associated with mutations in the Proteinase Inhibitor 12 (PI12) gene. A 26-year-old male presented with progressive myoclonus epilepsy and declining mental status. He had failed in university studies because of impaired attention, memory and concentration. Generalized seizures started to occur approximately once a month, and he developed myoclonus and progressive gait disturbances. Neuroimaging revealed mild atrophy and multiple periventricular white matter lesions, consistent with demyelination. He progressively declined and died at age 34. Neuropathologic examination revealed widespread involvement of the cerebral cortex by numerous round eosinophilic inclusions in neuronal perikarya and neuropil, predominantly within the deep cortical layers. Numerous inclusions were also found in the basal ganglia, thalamus, hippocampus, brain stem, spinal gray matter, and dorsal root ganglia. They were essentially absent from the cerebellum. The inclusions were immunopositive for antibodies raised against neuroserpin. The white matter lesions showed histologic features compatible with multiple sclerosis. Genetic analysis revealed a nucleotide substitution in codon 47 in one allele of the PI12 gene, resulting in a proline for leucine amino acid substitution (L47P). In summary, we report a case of neuroserpin encephalopathy associated with a novel PI12 mutation and complicated by coexistent multiple sclerosis.

Limited Unfolded Protein Response and Inflammation in Neuroserpinopathy
AbstractFamilial encephalopathy with neuroserpin inclusion bodies (FENIB) is a rare disease characterized by the deposition of multiple intracytoplasmic neuronal inclusions that contain mutated neuroserpin. Tg-Syracuse (Tg-Syr) mice express Ser49Pro mutated neuroserpin and develop clinical and neuropathological features of human FENIB. We used 8-, 34-, 45- and 80-week-old Tg-Syr mice to characterize neuroinflammation and the unfolded protein response (UPR) in a neurodegenerative disease in which abnormal protein aggregates accumulate within the endoplasmic reticulum (ER). There were scattered neuroserpin inclusions in Tg-Syr mice at 8 weeks of age; the numbers of neurons involved and the amount of neuroserpin per neuron increased with age throughout the CNS to 80 weeks of age; no similar inclusions were found in wild type (Tg-WT) mice at any age. Increases in numbers of astrocytes and microglia occurred at advanced disease stages. Among 22 markers in 80-week-old Tg-Syr mice, only II1b and II10rb mRNAs in the somatosensory cortex and CxCl10 and Il10rb mRNAs in the olfactory bulb were upregulated when compared with Tg-WT mice indicating a limited relationship between neuroserpin inclusions and inflammatory responses. The changes were accompanied by a transient increase in expression of Xbp1 spliced at 45 weeks and increased ERdJ4 mRNAs at 80 weeks. The sequestration of UPR activators GRP78 and GRP94 in neuroserpin inclusions might explain the limited UPR responses despite the accumulation of neuroserpin in the ER in this FENIB mouse model.
