Vgamma9/Vdelta2 T lymphocytes in Italian patients with Behçet's disease: evidence for expansion, and tumour necrosis factor receptor II and interleukin-12 receptor beta1 expression in active disease.

Behçet's disease is a multisystem disease in which there is evidence of immunological dysregulation. It has been proposed that gamma/delta T cells are involved in its pathogenesis. The aim of the present study was to assess the capacity of gamma/delta T cells with phenotype Vgamma9/Vdelta2, from a group of Italian patients with Behçet's disease, to proliferate in the presence of various phosphoantigens and to express tumour necrosis factor (TNF) and IL-12 receptors. Twenty-five patients and 45 healthy individuals were studied. Vgamma9/Vdelta2 T cells were analyzed by fluorescence activated cell sorting, utilizing specific monoclonal antibodies. For the expansion of Vgamma9/Vdelta2 T cells, …

LEMON-DERIVED EXTRACELLULAR VESICLES EXERT ANTI-INFLAMMATORY EFFECTS BY INHIBITING THE ERK/NF-KB PATHWAY

nflammation can be the leading cause of several diseases, including cancer, diabetes, and ulcerative colitis; however, the existing anti-inflammatory drugs cause side effects. For these reasons, it is necessary to find new supportive therapeutic agents. In recent years, plant-derived extracellular vesicles (PDEVs) are gaining increasing interest in the scientific community as they have been found to possess a variety of biological properties; among those, the anti-inflammatory effects have been described by different groups that evaluated the effects of PDEVs in in vitro and in vivo models. We successfully isolated and characterized extracellular vesicles from Citrus limon juice (LEVs) and …
