Tumor necrosis factor (TNF)-dependent sites of action in the generation of autoimmune inflammation have been defined by targeted disruption of TNF in the C57BL/6 mouse strain. C57BL/6 mice are susceptible to an inflammatory, demyelinating form of experimental autoimmune encephalomyelitis (EAE) induced by the 35-55 peptide of myelin oligodendrocyte(More)
Neuropathologic abnormalities can be sufficiently characteristic to suggest the genetic basis of some hereditary neuropathies such as those associated with mutations in MPZ, GJB1, GDAP1, MTMR2, SH3TC2, PRX, FGD4, and LMNA. We analyzed the morphologic features of 9 sural nerve biopsies from 6 patients with mutations of mitofusin 2. All patients presented in(More)
In studying autoimmune diseases of the human peripheral nervous system (PNS), in vitro studies involving the use of cultured rat Schwann cells, neurons, and disease-inducing immune system cells have provided basic information about disease pathogenesis. For example, T-cells that induce experimental allergic neuritis have been shown in vitro to damage(More)
The clinical, electrophysiological and pathological features and prognosis of 34 patients with peripheral neuropathy caused by necrotizing vasculitis were evaluated. The causes included polyarteritis nodosa and its Churg-Strauss variant, rheumatoid arthritis, undifferentiated connective tissue disease, Wegener's granulomatosis, primary Sjögren's disease,(More)
Focal cortical dysplasia type IIB with Ballon cells is a developmental malformation of the cerebral cortex highly associated with epilepsy. As a strategy to define the embryonic origin and neurochemical phenotype of cells in this disease, we probed specimens (n = 10) resected during epilepsy surgery with a panel of 13 antibodies recognizing proteins(More)
Early pathological studies in patients with acute and chronic inflammatory demyelinating neuropathies, and the animal model experimental autoimmune neuritis (EAN) showed similarities in the process of demyelination. These studies focused on compact myelin proteins and peptides as targets of immune attack in Guillain-Barré syndrome (GBS), chronic(More)
OBJECTIVE The aim of this two-year prospective study was to examine the relationship between multiple aspects of life-event stress and relapse in multiple sclerosis (MS) patients. BACKGROUND Few studies have defined the critical features of this life-event stress; for example, stressor duration, frequency, severity, disease-dependency, valency, or(More)
We describe 5 infants (4 male, 1 female) with a severe intractable form of motor-sensory axonal neuropathy. All became ventilator-dependent, 4 have since died and 1 remains static. Diaphragmatic paralysis was an early feature with generalized neuropathy evolving rapidly. Nerve conduction studies and biopsies were consistent with axonal disease. This(More)
Studies were conducted in experimental allergic neuritis (EAN) to evaluate the possible interaction of cellular and humoral immune mechanisms in the demyelinating process. EAN was induced in Lewis rats by passive transfer of T cells reactive to P2 myelin protein or by active immunisation with whole myelin. Animals were then given systemic antimyelin(More)
Over a 33-year period, 260 patients (< 17 years of age; 119 males, 141 females) from New South Wales, Australia who had peripheral neuropathies confirmed by nerve biopsy, were studied. Of these, 50 infants presented with symptoms or signs of neuropathy under 1 year of age: including 24 patients with demyelinating neuropathies and 21 axonal neuropathies; a(More)
