Anti-aquaporin-4 antibodies in neuromyelitis optica: how to prove their pathogenetic relevance?
The discovery of a specific autoantibody response in neuromyelitis optica (NMO) patients, which selectively targets astrocytic end feet at the glia limitans1 and which is directed against the water channel aquaporin-4 (AQP-4)2 was a milestone in defining this disease entity and profoundly changed our view regarding its pathogenesis.3 Indirect evidence, coming from clinical observations and path...
متن کاملAnti-aquaporin-4 monoclonal antibody blocker therapy for neuromyelitis optica.
OBJECTIVE Neuromyelitis optica (NMO) is an inflammatory demyelinating disease of the central nervous system. Circulating autoantibodies (NMO-immunoglobulin [Ig]G) against astrocyte water channel aquaporin-4 (AQP4) cause complement- and cell-mediated astrocyte damage with consequent neuroinflammation and demyelination. Current NMO therapies, which have limited efficacy, include immunosuppression...
متن کاملDiscovering ligands for a microRNA precursor with peptoid microarrays
We have screened peptoid microarrays to identify specific ligands for the RNA hairpin precursor of miR-21, a microRNA involved in cancer and heart disease. Microarrays were printed by spotting a library of 7680 N-substituted oligoglycines (peptoids) onto glass slides. Two compounds on the array specifically bind RNA having the sequence and predicted secondary structure of the miR-21 precursor h...
متن کاملLongitudinally extensive transverse myelitis with and without aquaporin 4 antibodies.
IMPORTANCE Aquaporin 4 antibody (AQP4-Ab)-negative patients with longitudinally extensive transverse myelitis (LETM) behave differently from those with AQP4-Ab. Aquaporin 4 antibody-negative neuromyelitis optica (NMO) is rare when good assays are used. OBJECTIVE To assess if AQP4-Ab-negative patients with LETM share similar disease characteristics with AQP4-Ab-positive patients or whether the...
متن کاملDiscovery of nanomolar ligands for 7-transmembrane G-protein-coupled receptors from a diverse N-(substituted)glycine peptoid library.
Screening a diverse, combinatorial library of ca. 5000 synthetic dimer and trimer N-(substituted)glycine "peptides" yielded novel, high-affinity ligands for 7-transmembrane G-protein-coupled receptors. The peptoid library was efficiently assembled using readily available chemical building blocks. The choice of side chains was biased to resemble known ligands to 7-transmembrane G-protein-coupled...
