Humoral Response to SARS-COV-2 Vaccination in Patients with Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder: A Real-World Study.

Introduction: The risk of SARS-CoV-2 infection or severe coronavirus disease 2019 (COVID-19) has been shown to increase in patients with multiple sclerosis (MS). Vaccination is recommended in this patient population, and the effect of disease-modifying treatments (DMTs) on response to vaccination should be considered.

Methods: This prospective, observational, cross-sectional study investigated humoral response after COVID-19 vaccination as well as possible predictors for response in patients with MS and other neuroinflammatory diseases who received DMTs in routine clinical practice in Spain.

Treatment with natalizumab during pregnancy in multiple sclerosis: The experience of implementing a clinical practice protocol (NAP-30).

Background: Pregnancy planning in women with highly active multiple sclerosis (HAMS) who need a high-efficacy disease-modifying therapy (heDMT) currently requires a careful risk-benefit evaluation. This includes minimizing fetal drug toxicity and preventing MS reactivation. We describe our experience with natalizumab in women with HAMS and unplanned pregnancy by implementing a clinical practice protocol (NAP-30) designed to maintain the effectiveness of natalizumab during pregnancy, reduce fetal exposure and prevent complications.

Generation of RRMS and PPMS specific iPSCs as a platform for modeling Multiple Sclerosis.

The advent of cellular reprogramming technology converting somatic cells into induced pluripotent stem cells (iPSCs) has revolutionized our understandings of neurodegenerative diseases that are otherwise hard to access and model. Multiple Sclerosis (MS) is a chronic demyelinating, inflammatory disease of central nervous system eventually causing neuronal death and accompanied disabilities. Here, we report the generation of several relapsing-remitting MS (RRMS) and primary progressive MS (PPMS) iPSC lines from MS patients along with their age matched healthy controls from peripheral blood mononuclear cells (PBMC).

Prevention of rebound effect after natalizumab withdrawal in multiple sclerosis. Study of two high-dose methylprednisolone schedules.

Background: Natalizumab (NTZ) is a disease-modifying treatment (DMT) in multiple sclerosis (MS) whose discontinuation can produce a "rebound effect", consisting of severe clinical deterioration and/or evidence of disease reactivation on magnetic resonance imaging (MRI).

Objective: To analyze the efficacy of two treatment schedules with intravenous methylprednisolone (IVMP) administered during the washout period of natalizumab (i.e.

Possible Influence of the Route of Treatment Administration on Treatment Adherence in Patients With Multiple Sclerosis.

Purpose: Multiple sclerosis is a chronic, demyelinating, and degenerative disease of the central nervous system with an immune-based pathologic origin. The present pilot study aimed to assess whether the change in the route of treatment administration is associated with a variation in adherence and whether there is a change in quality of life, treatment satisfaction, and fatigue.

Methods: Patients with relapsing-remitting multiple sclerosis who were >18 years of age and who used to receive immunomodulatory parenteral treatment and were ready to change administration route were eligible for the study.

Production via good manufacturing practice of exofucosylated human mesenchymal stromal cells for clinical applications.

Background: The regenerative and immunomodulatory properties of human mesenchymal stromal cells (hMSCs) have raised great hope for their use in cell therapy. However, when intravenously infused, hMSCs fail to reach sites of tissue injury. Fucose addition in α(1,3)-linkage to terminal sialyllactosamines on CD44 creates the molecule known as hematopoietic cell E-/L-selectin ligand (HCELL), programming hMSC binding to E-selectin that is expressed on microvascular endothelial cells of bone marrow (BM), skin and at all sites of inflammation.

NIK controls classical and alternative NF-κB activation and is necessary for the survival of human T-cell lymphoma cells.

Purpose: Peripheral T-cell lymphomas (PTCL) are a heterogeneous entity of neoplasms with poor prognosis, a lack of effective therapies, and a largely unknown molecular pathology. Deregulated NF-κB activity has been associated with several lymphoproliferative diseases, but its importance in T-cell lymphomagenesis is poorly understood. We investigated the function of the NF-κB-inducing kinase (NIK), in this pathway and its role as a potential molecular target in T-cell lymphomas.
