Is TNF-α really involved in giant cell arteritis pathogenesis?

2013

Giant cell arteritis (GCA) is the most frequent vasculitis in people >50 years, and glucocorticoids (GC) remain the cornerstone of the treatment. However, this long-term treatment is responsible for numerous GC-related complications.1 Thus, reliable GC-sparing drugs need to be explored. Seror et al 2 have recently reported the inefficacy of adalimumab, a humanised anti-TNF-α therapy, as a GC-sparing drug in the treatment of GCA. These clinical results contrast with previous studies reporting a production of TNF-α by giant cells and macrophages in GCA lesions.3 However, recent advance in the knowledge of GCA pathogenesis have shown that macrophages and giant cells are not involved in the fir…

Regulation of Protein-DNA Interactions at the Interferon-gamma Gene Promoter by Corticosteroids: Implications for Inflammatory Bowel Diseases

miR-155 inhibition sensitizes CD4+ Th cells for TREG mediated suppression.

2009

BackgroundIn humans and mice naturally occurring CD4(+)CD25(+) regulatory T cells (nTregs) are a thymus-derived subset of T cells, crucial for the maintenance of peripheral tolerance by controlling not only potentially autoreactive T cells but virtually all cells of the adaptive and innate immune system. Recent work using Dicer-deficient mice irrevocably demonstrated the importance of miRNAs for nTreg cell-mediated tolerance.Principal findingsDNA-Microarray analyses of human as well as murine conventional CD4(+) Th cells and nTregs revealed a strong up-regulation of mature miR-155 (microRNA-155) upon activation in both populations. Studying miR-155 expression in FoxP3-deficient scurfy mice …

A rapid and simple multiparameter assay to quantify spike-specific CD4 and CD8 T cells after SARS-CoV-2 vaccination: A preliminary report

2021

mRNA and Adenovirus vaccines for COVID-19 are used to induce humoral and cell-mediated immunity, with the aim to generate both SARS-CoV-2 B and T memory cells. In present study, we described a simple assay to detect and quantify Spike-specific CD4+ and CD8+ T cell responses induced by vaccination in healthy donors and in subjects with B cell compart impairment, in which antibody response is absent due to primary immunodeficiencies or CD20 depleting therapy. We detect and quantified memory T cell immune responses against SARS-CoV-2 evocated by vaccination in both groups, irrespective to the humoral response. Furthermore, we identified TNF-α as the main cytokine produced by T memory cells, af…

Evidence of a sudden increase in the nuclear size of proton-rich silver-96

2021

Understanding the evolution of the nuclear charge radius is one of the long-standing challenges for nuclear theory. Recently, density functional theory calculations utilizing Fayans functionals have successfully reproduced the charge radii of a variety of exotic isotopes. However, difficulties in the isotope production have hindered testing these models in the immediate region of the nuclear chart below the heaviest self-conjugate doubly-magic nucleus 100Sn, where the near-equal number of protons (Z) and neutrons (N) lead to enhanced neutron-proton pairing. Here, we present an optical excursion into this region by crossing the N = 50 magic neutron number in the silver isotopic chain with th…

Skin conductance measurement for the assessment of analgosedation adequacy in infants treated with mechanical ventilation: A multicenter pilot study

2020

Background Patients treated in neonatal/pediatric intensive care units (N/PICUs) are frequently exposed to pain. To assess its severity, several behavioral and behavioral-physiological scales are used, but their usefulness is limited. It is therefore justified to search for additional methods to assess the adequacy of analgesia and sedation in these patients. Objectives To evaluate the usefulness of skin conductance (SC) measurement in the assessment of analgosedation quality in infants requiring mechanical ventilation treated in N/PICUs. Material and methods Thirty infants aged 6-208 days treated in 6 N/PICUs, mechanically ventilated and receiving analgosedation, were included for the stud…

The effect of social information from live demonstrators compared to video playback on blue tit foraging decisions.

2019

Video playback provides a promising method to study social interactions, and the number of video playback experiments has been growing in recent years. Using videos has advantages over live individuals as it increases the repeatability of demonstrations, and enables researchers to manipulate the features of the presented stimulus. How observers respond to video playback might, however, differ among species, and the efficacy of video playback should be validated by investigating if individuals’ responses to videos are comparable to their responses to live demonstrators. Here, we use a novel foraging task to compare blue tits’ (Cyanistes caeruleus) responses to social information from a live …

Safety and efficacy outcomes after intranasal administration of neural stem cells in cerebral palsy : a randomized phase 1/2 controlled trial

2023

Abstract Background Neural stem cells (NSCs) are believed to have the most therapeutic potential for neurological disorders because they can differentiate into various neurons and glial cells. This research evaluated the safety and efficacy of intranasal administration of NSCs in children with cerebral palsy (CP). The functional brain network (FBN) analysis based on electroencephalogram (EEG) and voxel-based morphometry (VBM) analysis based on T1-weighted images were performed to evaluate functional and structural changes in the brain. Methods A total of 25 CP patients aged 3–12 years were randomly assigned to the treatment group (n = 15), which received an intranasal infusion of NSCs loade…
