In-depth molecular pathogenesis of ground-glass nodular lung adenocarcinoma has not been well understood. The objectives of this study were to identify genomic alterations in ground-glass nodular lung adenocarcinomas and to investigate whether viral transcripts were detected in these tumors. Nine patients with pure (n = 4) and part-solid (n = 5) ground-glass nodular adenocarcinomas were included. Six were females with a median age of 58 years. We performed targeted exon sequencing and RNA sequencing...

Impairments in oligodendrocyte development and resultant myelination deficits appear as a common denominator to all neurological diseases. An optimal in utero environment is obligatory for normal fetal brain development and later life brain functioning. Late embryonic and early postnatal brains from F1 rat born to protein malnourished mothers were studied through a combination of immunocytochemical and quantitative PCR assay for analyzing the relative expression of platelet-derived growth factor receptor-α (PDGFRα), myelin-associated glycoprotein (MAG), proteolipid protein (PLP), and myelin oligodendrocyte glycoprotein (MOG) to determine oligodendrocyte genesis, differentiation, maturation, and myelination...

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) has been widely accepted for treating superficial esophageal squamous cell carcinoma (SESCC). However, long-term outcomes of ESD and esophagectomy for SESCC have not been compared. We compared the clinical outcomes of ESD and esophagectomy in a matched cohort. METHODS: Patients who underwent ESD and esophagectomy for SESCC were included. We selected SESCCs without obvious submucosal invasion from the surgical database by reviewing endoscopic images...

Late-onset neutropenia after rituximab therapy (LONART) is defined as a fall in the absolute neutrophil count below 500/mm3 at least 3 weeks after rituximab infusion, in the absence of any other explanation. LONART is rare during dysimmune conditions but can be life-threatening. We report on two patients with LONART and associated neurological relapse occurring in myelin oligodendrocyte glycoprotein (MOG)-antibody spectrum disorders. Rituximab was reintroduced in one patient, while the second patient was switched to tocilizumab...

Over the past few years, new-generation cell-based assays have demonstrated a robust association of autoantibodies to full-length human myelin oligodendrocyte glycoprotein (MOG-IgG) with (mostly recurrent) optic neuritis, myelitis and brainstem encephalitis, as well as with acute disseminated encephalomyelitis (ADEM)-like presentations. Most experts now consider MOG-IgG-associated encephalomyelitis (MOG-EM) a disease entity in its own right, immunopathogenetically distinct from both classic multiple sclerosis (MS) and aquaporin-4 (AQP4)-IgG-positive neuromyelitis optica spectrum disorders (NMOSD)...

BACKGROUND AND PURPOSE: Autoimmune responses can occur when antigens from the central nervous system are presented to lymphocytes in the periphery or central nervous system in several neurological diseases. However, whether autoimmune responses emerge after brain ischemia and their impact on clinical outcomes remains controversial. We hypothesized that brain ischemia facilitates the genesis of autoimmunity and aggravates ischemic brain injury. METHODS: Using a mouse strain that harbors a transgenic T-cell receptor to a central nervous system antigen, MOG35-55 (myelin oligodendrocyte glycoprotein) epitope (2D2), we determined the anatomic location and involvement of antigen-presenting cells in the development of T-cell reactivity after brain ischemia and how T-cell reactivity impacts stroke outcome...

REVIEW
C Alves Do Rego, N Collongues
The new diagnostic classification of neuromyelitis optica spectrum disorder (NMOSD) in 2015 highlights the central role of biomarkers, such as antibodies against aquaporin-4 (AQP4-Ab), in diagnosis. Also, in approximately 20-25% of patients without AQP4-Ab (NMOSDAQP4- ) the presence of an antibody directed against myelin oligodendrocyte glycoprotein (MOG) characterizes a specific population of NMOSD patients (NMOSDMOG+ ), according to their demographic and clinical data and prognoses. While double-seronegative cases (NMOSDNEG ) have not been fully described, they may correspond to the very first patients with opticospinal demyelination reported by Devic and Gault in 1894...

Antibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been found in some cases diagnosed as seronegative neuromyelitis optica spectrum disorder (NMOSD). MOG-IgG allowed the identification of a subgroup with a clinical course distinct from that of NMOSD patients who are seropositive for aquaporin-4-IgG antibodies. MOG-IgG is associated with a wider clinical phenotype, not limited to NMOSD, with the majority of cases presenting with optic neuritis (ON), encephalitis with brain demyelinating lesions, and/or myelitis...

We hypothesized that Octamer-binding transcription factor 4 (OCT4) inhibition would have therapeutic benefits in Testicular germ cell tumors (TGCT). To identify inhibitors of OCT4, a chemical library was screened using a luciferase reporter system under the control of an OCT4 response element. A compound named KRIBB53 was identified based on its blocking of OCT4-dependent luciferase activation. When NCCIT cells were exposed to KRIBB53, the expression levels of OCT4 target genes, such as NANOG and USP44, were inhibited with an IC50 of 13 and 15 μM, respectively...

We report the case of a patient who presented with progressive unsteadiness and narcoleptic attacks followed by behavioral change and psychosis, without visual disturbances or seizures. MRI revealed multiple areas of fluid attenuation inversion recovery (FLAIR) high-intensity lesions involving the cerebellum, brainstem, thalamus and third ventricular peri-ependymal region consistent with demyelination. Both the serum myelin oligodendrocyte glycoprotein-antibodies (MOG-Abs) and cerebral spinal fluid (CSF) anti-N-methyl-d-as-partate receptor (NMDAR) antibodies were positive using transfected cell based assays...

PURPOSE OF REVIEW: Neuroimmunological diseases encompass a wide spectrum of diseases in children. Apart from the discovery of autoantibodies affecting primarily grey matter structures and the improved clinical characterization of rare entities such as N-methyl D-aspartate receptor-R- encephalitis, important strides have also been made in autoimmune-mediated white matter diseases, including paediatric multiple sclerosis (pedMS) and other acute demyelinating syndromes (ADS) often associated with antibodies (abs) against myelin-oligodendrocyte-glycoprotein (MOG)...
