We recently isolated a cDNA clone that encodes the melanocyte lineage-specific antigen glycoprotein (gp)100. Antibodies directed against gp100 are an important tool in diagnosis of human melanoma. Since is highly expressed melanocytic cells, we investigated whether this might serve as target for antimelanoma cytotoxic T lymphocytes (CTL). Here, demonstrate tumor-infiltrating (TIL) derived from melanoma patient (TIL 1200) gp100. HLA-A2.1+ cells lysed by TIL patient. In addition, murine double...

All developed severe prodromal weight loss or diarrhea followed by cognitive...
<h3>Objective</h3> Antibodies against glutamic acid decarboxylase 65 (anti-GAD65) are associated with a number of neurologic syndromes. However, their pathogenic role is controversial. Our objective was to describe clinical and paraclinical characteristics anti-GAD65 patients analyze response immunotherapy. <h3>Methods</h3> Retrospectively, we studied (n = 56) positive any symptom. We tested serum CSF ELISA, immunohistochemistry, cell-based assay. Accordingly, set cutoff value 10,000 IU/mL...
Abstract In a randomized clinical trial of 86 hospitalized COVID-19 patients comparing standard care to treatment with 300mL convalescent plasma containing high titers neutralizing SARS-CoV-2 antibodies, no overall benefit was observed. Using comprehensive translational approach, we unravel the virological and immunological responses following disentangle which may should be focus future studies. Convalescent is safe, does not improve survival, has effect on disease course, nor enhance viral...
We describe the effect on neonate of administration rituximab to a woman with idiopathic thrombocytopenic purpura (ITP). Rituximab, an anti-CD20 antibody, was given weekly for 4 weeks ITP in her third trimester pregnancy. One month after last healthy girl born. She had normal growth and development during first six months. At birth, B-lymphocytes were not detectable. Rituximab levels mother 24000 6700 ng/mL, respectively. Only 7 cases pregnancy described. No adverse events are described...
Enterocyte damage is the hallmark of coeliac disease (CD) resulting in malabsorption. Little known about recovery enterocyte and its clinical consequences. Serum intestinal fatty acid binding protein (I-FABP) a sensitive marker to study damage.To evaluate severity adult-onset CD course upon gluten-free diet (GFD). Furthermore, correlation among damage, autoantibodies histological abnormalities during studied.Serum I-FABP levels were determined 96 biopsy-proven adult patients 69 repeatedly...
To assess the clinical relevance of a positive voltage-gated potassium channel (VGKC) test in patients lacking antibodies to LGI1 and Caspr2.VGKC-positive were tested for Caspr2 antibodies. Patients both matched (1:2) VGKC-negative patients. Clinical paraclinical criteria used blindly determine evidence autoimmune inflammation groups. with an inconclusive VGKC titer analyzed same way.A total 1,455 by radioimmunoassay. Fifty-six positive, 50 whom available be included. Twenty-five had (n =...
Leucine‐rich glioma‐inactivated1 (LGI1) encephalitis is an antibody‐associated inflammation of the limbic area. An autoimmune etiology suspected but not yet proven. We performed human leukocyte antigen (HLA) analysis in 25 nontumor anti‐LGI1 patients and discovered a remarkably strong HLA association. HLA‐DR7 was present 88% compared to 19.6% healthy controls ( p = 4.1 × 10 −11 ). HLA‐DRB4 all 46.5% 1.19 −7 These findings support hypothesis. exploratory small group 4 tumor‐LGI1 patients. The...
<h3>Objective</h3> To provide detailed long-term outcome data of children and adolescents following pediatric anti-<i>N</i>-methyl-d-aspartate receptor (anti-NMDAR) encephalitis, to identify neuropsychological impairments, evaluate the influence these factors on quality life (QoL). <h3>Methods</h3> All Dutch diagnosed with anti-NMDAR encephalitis were identified. Patients currently aged 4 years or older included in follow-up study, consisting a visit our clinic for interview standardized...

Background: Thyroid dysfunction is among the most common adverse effects during anti-programmed cell death 1 (PD-1) immunotherapy, and alongside correlations with elevated anti-thyroid antibodies (ATAb), studies have found survival. However, exact relations remain to be clarified. We, therefore, aimed at clarifying relationship between thyroid dysfunction, ATAbs, survival in anti-PD-1 treated cancer patients. Methods: We included 168 patients nonsmall-cell lung carcinoma, renal metastatic...
Quantitative or qualitative differences in immunity may drive clinical severity COVID-19. Although longitudinal studies to record the course of immunological changes are ample, they do not necessarily predict progression at time hospital admission. Here we show, by a machine learning approach using serum pro-inflammatory, anti-inflammatory and anti-viral cytokine anti-SARS-CoV-2 antibody measurements as input data, that COVID-19 patients cluster into three distinct immune phenotype groups....
