A Monoclonal Antibody to M-Phase Phosphoprotein 1/Kinesin-Like Protein KIF20B.

A Monoclonal Antibody to M-Phase Phosphoprotein 1/Kinesin-Like Protein KIF20B. Monoclon Antib Immunodiagn Immunother. 2019 Jun 28;: Authors: Fritzler MJ, Brown RD, Zhang M Abstract Kinesin-like protein KIF20B, originally named M-phase phosphoprotein 1 (MPP1), is a plus-end-directed kinesin-related protein that exhibits in vitro microtubule-binding and -bundling properties as well as microtubule-stimulated ATPase activity. It has been characterized as a slow molecular motor that moves toward the plus-end of microtubules. Human autoantibodies directed against KIF20B have been described in up to 25% of patients with idiopathic ataxia and less commonly in other neuropathies and autoinflammatory conditions. One of the limitations of research into the structure and function of KIF20B has been a reliable monoclonal antibody that can be used in a variety of applications. To establish a reference standard for anti-KIF20B immunoassays and facilitate studies on the role of KIF20B in developmental cell biology, we developed an IgG1 monoclonal antibody, 10C7, which reacts with the cognate KIF20B protein in Western immunoblots and in addressable laser bead immunoassays. In HEp2 cells, leptomeningeal pericytes, and transfected HEK293T cells, indirect immunofluorescence studies showed that reactivity was mainly localized to a proportion of interphase nuclei, but during metaphase, it was redistributed throughout the cytoplasm and perichromatin mass. Later in telophase/ana...

Abstract Autoimmune encephalitides, with an estimated incidence of 1.5 per million population per year, although described only 15 years ago, have already had a remarkable impact in neurology and paved the field to autoimmune neuropsychiatry. Many patients traditionally presented with aberrant behavior, especially of acute or subacute onset, and treated with anti-psychotic therapies, turn out to have a CNS autoimmune disease with pathogenic autoantibodies against synaptic antigens responding to immunotherapies. The review describes the clinical spectrum of these disorders, and the pathogenetic role of key autoanti...

This article will update and review the Miller Fisher variants (MFV) of Guillain–Barré syndrome (GBS) including the clinical presentation, diagnostic testing, and treatment. Recent findings Although the diagnosis of GBS and MFV can be made on clinical grounds, cerebrospinal fluid (CSF) analysis, nerve conduction studies, imaging (e.g. ultrasound and MRI), and serologic testing can help to confirm the diagnosis. Some patients may need immunotherapy with either intravenous immunoglobulin (IVIg) or plasma exchange, and recent studies suggest that complement inhibition combined with IVIg could be of benefit, bu...

Conclusion In our series, neurochondrin autoimmunity was usually accompanied by a nonparaneoplastic rapidly progressive rhombencephalitis with poor neurologic outcomes. Other phenotypes and occasional paraneoplastic causes may occur.

We report herein incidence and clinical features of hyperacute onset PCD, a vertebrobasilar stroke mimic. We performed a retrospective analysis of all suspected PCD cases referred to the Udine University Hospital between 2009 and 2017. Our center provides the only neuroimmunology laboratory for three provinces of the Friuli-Venezia Giulia region, Italy (983,190 people as of January 1, 2017). Inclusion criteria were (1) abrupt onset of neurological symptoms; (2) initial consideration of a vascular etiology; (3) final diagnosis of "definite PCD." We also carried out a systematic review of the literature in order to...

Abstract To report three cases of autoimmune ataxia patients with positive neurochondrin (NCDN) antibodies. Patients with unknown cerebellar ataxia were screened for autoimmune cerebellar ataxia (ACA)-related antibodies, including glutamic acid decarboxylase 65 (GAD65), delta/notch-like epidermal growth factor-related receptor (Tr/DNER), zinc finger protein 4 (ZIC4), inositol 1,4,5-triphosphate receptor 1 (ITPR1), Homer protein homologue 3 (Homer-3), neurochondrin (NCDN), Purkinje cell antibody 2 (PCA-2) and carbonic anhydrase-related protein VII (CARPVII). The antibodies were assessed by indirect immunofluorescen...
