Myasthenia gravis (MG) is a T cell-dependent, B cell-mediated, and complement-dependent autoimmune disease. Lymphocyte activation gene-3 (LAG-3; CD223) is an immune checkpoint protein that plays an im...
When testing the proliferative activity of 14 strains of permafrost microorganisms in the reaction of blast transformation of human lymphocytes in vitro, a strain (Alcaligenes sp.) with mitogen proper...
Upon lymphocyte stimulation, accumulation of intracellular NAD(H) reflects the strength of antigen receptor signals and controls the rate of cell cycle entry and proliferation (see related Research Ar...
Deficiencies in Mannosidase β (MANBA) are associated with neurological abnormalities and recurrent infections. The single nucleotide polymorphism located in the 3′UTR of MANBA, rs7665090, was found to...
Zinc is important for a balanced immune system, but the mechanisms are not yet fully elucidated. One possibility is an interaction of zinc with the tricarboxylic acid cycle (TCA), in which zinc inhibi...
After allogeneic (MLC) or superantigen stimulation, the interferon-γ (IFNγ) production is quantified by ELISA and T cell subpopulations are determined by Western Blot. Intracellular concentrations of ...
These results may explain the immunosuppressive effect of blood products anticoagulated by citrate. In addition, high citrate consumption may lead to immunosuppressive effects, so upper limits for cit...
Lymphocyte activation gene-3 (LAG-3) inhibits T cell activation and interferes with the immune response by binding to MHC-II. As antigen presentation is central in rheumatoid arthritis (RA) pathogenes...
Plasma levels of soluble (s) LAG-3 were measured in early RA patients (eRA, n = 99) at baseline and after 12 months on a treat-to-target protocol, in self-reportedly healthy controls (HC, n = 32), and...
Baseline sLAG-3 in the plasma was increased in eRA compared to HC and remained significantly elevated throughout 12 months of treatment. A high level of sLAG-3 at baseline was associated with the pres...
sLAG-3 in the plasma and synovial fluid is increased in both early and chronic RA patients, particularly in the inflamed joint. High levels of sLAG-3 are associated with autoantibody seropositivity an...
T cell activation and programming from their naïve/resting state, characterized by widespread modifications in chromatin accessibility triggering extensive changes in transcriptional programs, is orch...
We analyzed the transcription signature of the main variants from PRDM1 (BLIMP1a and BLIMP1b) and PRDM2 (RIZ1 and RIZ2) genes, in human T lymphocytes and Jurkat cells overexpressing PRDM2 cDNAs follow...
T lymphocyte activation induced an early increase of RIZ2 and RIZ1 followed by BLIMP1b increase and finally by BLIMP1a increase. The "first" and the "second" signals shifted the balance towards the PR...
This study provides the first characterization of PRDM2 in T-lymphocyte activation/differentiation and novel insights on PRDM1 and PRDM2 transcription regulation during initial activation phases....
Despite immune-reconstitution, after TARc HIV-positive patients, neurocognitive disorders related to HIV-1 (HAND) have been observed in these patients. The diagnosis occurs, in most cases, in the adva...
Stress granules (SGs) and processing bodies (PBs) are membraneless cytoplasmic assemblies regulating mRNAs under environmental stress such as viral infections, neurological disorders, or cancer. Upon ...
Dysregulated T-cell activation is a hallmark of several autoimmune diseases such as rheumatoid arthritis (RA) and multiple sclerosis (MS). The lymphocyte cytosolic protein 2 (LCP2), also known as SLP-...
