These studies tested whether antigenic competition between T cells occurs. We generated CD8+ cell responses in H-2b mice against the dominant ovalbumin epitope SIINFEKL (ova8) and subdominant KRVVFDKL, using either vaccinia virus expressing (VV-ova) or peptide-pulsed dendritic cells. were visualized by major histocompatibility complex class I–peptide tetrameric molecules. Transfer of transgenic with high affinity for ova8 (OT1 cells) completely inhibited response host antigen-specific to...
Tezepelumab (AMG 157/MEDI9929), a first-in-class monoclonal antibody, targets thymic stromal lymphopoietin, cytokine that is implicated in the pathogenesis of atopic dermatitis (AD).We sought to evaluate efficacy and safety tezepelumab adults with moderate severe AD.In this phase 2a study (NCT02525094), 113 patients were randomized 1:1 subcutaneous 280 mg or placebo every 2 weeks, plus class 3 topical corticosteroids (TCS). The primary endpoint was week 12 response rate for ≥50% reduction...
MEDI2070 is a human monoclonal antibody that selectively inhibits interleukin 23 (IL23), cytokine implicated in the pathogenesis of Crohn's disease (CD). We analyzed its safety and efficacy treatment CD phase 2a study.We conducted double-blind, placebo-controlled study 119 adults with moderate to severe failed by tumor necrosis factor antagonists. Patients were randomly assigned (1:1) groups given (700 mg) or placebo intravenously at weeks 0 4. received open-label (210 subcutaneously every 4...
Blood tests to monitor disease activity, attack severity, or treatment impact in neuromyelitis optica spectrum disorder (NMOSD) have not been developed. This study investigated the relationship between serum glial fibrillary acidic protein (sGFAP) concentration and NMOSD activity assessed of inebilizumab treatment.N-MOmentum was a prospective, multicenter, double-blind, placebo-controlled, randomized clinical trial adults with NMOSD. sGFAP levels were measured by single-molecule arrays...

Multimeric peptide/class II MHC staining reagents were synthesized and shown to bind with appropriate specificity T cell hybridomas. A small, expanded population of cells detected one these in peptide-immunized C57BL/10 mice persisted for several months. This further on secondary immunization. Equating the extent binding this reagent receptor affinity, we saw little correlation immunizing peptide dose affinity at peak primary response. However, there was an inverse relation between apparent...
During activation T cells are thought to change their patterns of gene expression dramatically. To find out whether this is true for activated in animals, the genes expressed resting and 8 48 hr after were examined by using Affymetrix arrays. Gene arrays gave accurate comparisons different cell types because known vary during changed as expected. Of approximately 6,300 assessed arrays, about one-third appreciable extents any tested. Thus, express a surprisingly large diversity genes. The...

Abstract Sjögren’s disease (SjD) is a chronic, systemic autoimmune with no approved disease-modifying therapies. Dazodalibep (DAZ), novel nonantibody fusion protein, CD40 ligand antagonist that blocks costimulatory signals between T and B cells antigen-presenting cells, therefore may suppress the wide spectrum of cellular humoral responses drive autoimmunity in SjD. This study was phase 2, randomized, double-blinded, placebo (PBO)-controlled trial DAZ crossover stage two distinct populations...
Objective To investigate relationships between serum neurofilament light chain (sNfL), ubiquitin C-terminal hydrolase L1 (sUCHL1), tau (sTau) and glial fibrillary acidic protein (sGFAP) levels disease activity/disability in neuromyelitis optica spectrum disorder (NMOSD), the effects of inebilizumab on these biomarkers N-MOmentum. Methods N-MOmentum randomised participants to receive or placebo with a controlled period (RCP) 28 weeks an open-label follow-up ≥2 years. The sNfL, sUCHL1, sTau...
Inebilizumab is an anti-CD19 antibody approved for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adults with aquaporin-4 autoantibodies. The relationship between B-cell, plasma-cell (PC), and immunoglobulin depletion longitudinal reductions NMOSD activity after inebilizumab was characterised post hoc exploratory analysis from N-MOmentum study (NCT02200770).Peripheral blood CD20+ B cells, PC gene signature, levels were assessed throughout (follow-up ≥2.5 years);...

AMG X, a human neutralizing monoclonal antibody (mAb) against soluble protein, caused thrombocytopenia, platelet activation, reduced mean arterial pressure, and transient loss of consciousness in cynomolgus monkeys after first intravenous administration. In vitro, X induced activation platelets from macaque species but not humans or baboons. Other similar mAbs the same pharmacological target failed to induce these vivo vitro effects. addition, protein was known be expressed on platelets,...
Specific and processive antitermination by bacteriophage lambda N protein in vivo vitro requires the participation of a large number Escherichia coli proteins (Nus factors), as well an RNA hairpin (boxB) within nut site nascent transcript. In this study we show that efficient, though nonprocessive, can be induced concentrations alone, even absence site. By adding back individual components system, also with nut+ is much more effective than alone. This effect abolished if competed away from...
