Acquisition of optimal TFH cell function is defined by specific molecular, positional, and TCR dynamic signatures
(2021)The development of follicular helper CD4 T (TFH) cells is a dynamic process resulting in a heterogenous pool of TFH subsets. However, the cellular and molecular determinants of this heterogeneity and the possible mechanistic ... -
Altered DNA methylation pattern characterizes the peripheral immune cells of patients with autoimmune hepatitis
(2022)Background and Aims: Little is known about the impact of DNA methylation modifications on autoimmune hepatitis (AIH) pathogenesis and therapeutic response. We investigated the potential alterations of DNA methylation in ... -
Curcumin mediates attenuation of pro-inflammatory interferon γ and interleukin 17 cytokine responses in psoriatic disease, strengthening its role as a dietary immunosuppressant
(2020)Curcumin exhibits anti-inflammatory properties and has been used for centuries in traditional medicine and as dietary supplement. Data from clinical trials has strengthened the notion that curcumin may exert an anti-inflammatory ... -
Differential effects of the two amino acid sensing systems, the GCN2 kinase and the mTOR complex 1, on primary human alloreactive CD4+ T-cells
(2016)Amino acid deprivation activates general control nonderepressible 2 (GCN2) kinase and inhibits mammalian target of rapamycin (mTOR), affecting the immune response. In this study, the effects of GCN2 kinase activation or ... -
The effect of hexanic extract of Serenoa repens on prostatic inflammation: results from a randomized biopsy study
(2019)Purpose: To evaluate the effect of hexanic extract of Serenoa repens (HESr) on prostatic inflammation in patients with diagnosed prostatic inflammation. Methods: Patients with prostatic inflammation histologically confirmed ... -
IDO decreases glycolysis and glutaminolysis by activating GCN2K, while it increases fatty acid oxidation by activating AhR, thus preserving CD4+ T-cell survival and proliferation
(2018)It is generally hypothesized in the literature that indoleamine 2,3-dioxygenase (IDO), by degrading L-tryptophan along the kynurenine pathway, suppresses CD4+ T-cell function by inducing apoptosis, inhibiting proliferation ... -
In human alloreactive CD4+ T-cells, dichloroacetate inhibits aerobic glycolysis, induces apoptosis and favors differentiation towards the regulatory T-cell subset instead of effector T-cell subsets
(2016)Although kidney transplantation is the best therapy for end-stage renal disease, rejection remains a concern, and currently available immunosuppressive agents contribute to morbidity and mortality. Thus, novel immunosuppressive ... -
Indoleamine 2,3-dioxygenase, by degrading L-tryptophan, enhances carnitine palmitoyltransferase i activity and fatty acid oxidation, and exerts fatty acid-dependent effects in human alloreactive CD4+ T-cells
(2016)Indoleamine 2,3-dioxygenase (IDO) is expressed in antigen presenting cells and by degrading L-tryptophan along the kynurenine pathway suppresses CD4+ T-cell proliferation, induces apoptosis and promotes differentiation ... -
Lamivudine plus interleukin-12 combination therapy in chronic hepatitis B: Antiviral and immunological activity
(2005)Interleukin-12 (IL-12) is an immunomodulatory cytokine that promotes cellular immunity. Pre-clinical data suggest that IL-12 inhibits hepatitis B virus (HBV) replication by stimulating interferon-gamma (IFN-γ) production. ... -
A role for human renal tubular epithelial cells in direct allo-recognition by CD4+ T-cells and the effect of ischemia-reperfusion
(2021)Direct allorecognition is the earliest and most potent immune response against a kidney allograft. Currently, it is thought that passenger donor professional antigen-presenting cells (APCs) are responsible. Further, many ... -
Tc2 response at the onset of COPD exacerbations
(2008)Background: T lymphocytes and especially the subpopulations of CD8+ cells are believed to have a key role in COPD pathophysiology, but there are only few data regarding the role of these cells in COPD exacerbation. Aim: ... -
Th1/Th2 cytokine pattern in bronchoalveolar lavage fluid and induced sputum in pulmonary sarcoidosis
(2005)Background: Sarcoidosis is thought to be a T-helper type 1 cytokine (Th2 cytokine) mediated disorder. Induced sputum (IS) has been proposed as a useful non-invasive method, mainly for the assessment of the airway diseases. ...
