local inflammatory processes in the gastric mucosa are followed by extensive immune cell infiltration, resulting in chronic active gastritis characterized by a marked infiltration of t(h)1 cytokine-producing cd4+ and cd8+t-cells objective. to investigate the correlation between cd4+/cd8+ t-cells in gastric mucosa with endoscopic appearance in chronic gastritis with or without h.pylori infection...
Abstract Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a devastating disease that confines ~65 million people worldwide to life of pain, severe exhaustion, cognitive deficits, flu-like symptoms, and postexertional malaise. We previously discovered decreased glycolysis, mitochondrial membrane potential, increased fatty acid oxidation in ME/CFS T cells. These features are commonl...
Background: Th1 cells preferentially express CXCR3, CCR5 and CCR6, while CCR3 and CCR4 are predominantly expressed by Th2 cell subsets. Multiple Sclerosis (MS) is a Th1 cell-dependant chronic inflammatory disease of the central nervous system, and immunomudolatory cytokines could alter the chemokine expression pattern of these lymphocyte subsets. Objective: This study was performed to measure c...
Molecular profiling of CD8 T cells in autochthonous melanoma identifies Maf as driver of exhaustion.
T cells infiltrating neoplasms express surface molecules typical of chronically virus-stimulated T cells, often termed "exhausted" T cells. We compared the transcriptome of "exhausted" CD8 T cells infiltrating autochthonous melanomas to those of naïve and acutely stimulated CD8 T cells. Despite strong similarities between transcriptional signatures of tumor- and virus-induced exhausted CD8 T ce...
Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...
Abstract Clinical trials of systemic T cell checkpoint blockade in GBM patients showed only disappointing results. This may be attributed part to the immunosuppressive components immune tumor microenvironment (iTME). Therefore, major efforts have been undertaken describe iTME on a single level. However, human data composition different regions (contrast enhancing center versus peripheral infilt...
Antiretroviral therapy (ART) only partially restores HIV-induced alterations in lymphocyte populations. We assessed B and T cell phenotypes in a cohort of children from a single centre in the United Kingdom with perinatally acquired HIV compared to healthy controls. The majority of HIV infected children (44 of 56) were on fully suppressive combination ART. Children with perinatally acquired HIV...
