PD‐L1Galectin 1immune escapeAlthough melanoma is considered one of the most immunogenic malignancies, spontaneous T‐cell responses to melanoma antigens are ineffective due to tumor cell‐intrinsic or microenvironment‐driven immune evasion mechanisms. For example, oncogenic BRAF V600E mutation in ...
PD-1:PD-L1 interactions contribute to the functional suppression of virus-specific CD8+ T lymphocytes in the liver. Mechanisms contributing to the development of chronic viral infections, including chronic hepatitis B virus (HBV) infections, are not well understood. We h......
It is well established that IFN-γ signalling promotes the expression of PD-L1 in the tumour microenvironment [42,43,44,45], and blocking the PD-1/PD-L1 axis could potentially enhance IFN-mediated inflammatory responses [46]. On the other hand, not all patients with serious irAEs in our...
T cell exhaustion; PD-1 pathway; HIV infection; vaccine-induced immunity; anti-PD-1; anti-PD-L1 1. Introduction Immune cell exhaustion is a hallmark of chronic viral infections. Continuous antigenic exposure drives the permanent activation of T cells, which, in turn, leads to a gradual loss...

Here, we confirmed that interferon-gamma (IFN-纬)-induced PD-L1 expression in melanoma cell lines. This increased expression was down-regulated by the reduction in phosphorylated STAT3 signaling via MET tyrosine kinase inhibitor treatment. Furthermore, immunoprecipitation and confocal ...
Results demonstrated that beta 3-AR antagonism lead to an immune response reactivation, partially dependent on the PD-1/PD-L1 signaling axis involvement. Indeed, beta 3-AR blockade on tumor-infiltrating lymphocytes (TILs) dampened their ability to secrete IFN-gamma, which in turn reduced the PD...
(IFN-g),thereby enhancing the anti-tumor effect of NK92-MI cells.Conclusions:Current data show that the immunomodulatory role of berberine is to enhance the cytotoxic effect of NK92-MI cells and inhibit tumor immune escape by reducing the expression of PD-L1.Our study provides a rationale ...
We found that IFN-gamma altered the expression of PD-L1, a major suppressor gene in the immune system during allograft rejection, in a strictly dose-dependent manner in BMSCs. Ten nanograms per milliliter IFN-gamma-incubated BMSCs significantly stimulated PD-L1 expression and suppressed T cell...
