Crucial roles of B7-H1 and B7-DC expressed on mesenteric lymph node dendritic cells in the generation of antigen-specific CD4+Foxp3+ regulatory T cells in the establishment of oral tolerance

open access: yesBlood, 2010
Abstract Oral tolerance is a key feature of intestinal immunity, generating systemic tolerance to fed antigens. However, the molecular mechanism mediating oral tolerance remains unclear. In this study, we examined the role of the B7 family members of costimulatory molecules in the establishment of oral tolerance.

Sarcoma immunotherapy. [PDF]

open access: yes, 2011
Much of our knowledge regarding cancer immunotherapy has been derived from sarcoma models. However, translation of preclinical findings to bedside success has been limited in this disease, though several intriguing clinical studies hint at the potential ...

Synergistic effects of IL-4 and TNFα on the induction of B7-H1 in renal cell carcinoma cells inhibiting allogeneic T cell proliferation [PDF]

open access: yes, 2014
BACKGROUND: The importance of B7-H molecules for the T cell/tumor communication and its impact on renal cell carcinoma (RCC) progression and prognosis has been recently described.

CHARACTERISTICS OF SIGNALING PATHWAYS MEDIATING A CYTOTOXIC EFFECT OF DENDRITIC CELLS UPON ACTIVATED Т LYMPHOCYTES AND NK CELLS

open access: yesМедицинская иммунология, 2014
. Cytotoxic/pro-apoptogenic effects of IFNα-induced dendritic cells (IFN-DCs) directed against Т-lymphocytes and NK cells were investigated in healthy donors.

Germline-encoded neutralization of a Staphylococcus aureus virulence factor by the human antibody repertoire. [PDF]

open access: yes, 2016
Staphylococcus aureus is both an important pathogen and a human commensal. To explore this ambivalent relationship between host and microbe, we analysed the memory humoral response against IsdB, a protein involved in iron acquisition, in four healthy ...

The PD-1/PD-L1 Axis and Virus Infections: A Delicate Balance [PDF]

open access: yes, 2019
Programmed cell death protein (PD-1) and its ligands play a fundamental role in the evasion of tumor cells from antitumor immunity. Less well appreciated is the fact that the PD-1/PD-L1 axis also regulates antiviral immune responses and is therefore ...

Specific zinc finger‐induced methylation of PD‐L1 promoter inhibits its expression

open access: yesFEBS Open Bio, 2019
DNA methylation of promoter regions is often associated with epigenetic silencing of gene expression, and DNA methyltransferase (DNMTs) has been used to suppress gene expression.

CpGs Induce Differentiation of Atlantic Salmon Mononuclear Phagocytes Into Cells With Dendritic Morphology and a Proinflammatory Transcriptional Profile but an Exhausted Allostimulatory Activity

open access: yesFrontiers in Immunology, 2019
Due to their ability to present foreign antigens and prime naïve T cells, macrophages, and dendritic cells (DCs) are referred to as professional antigen-presenting cells (APCs).

Hantavirus-driven PD-L1/PD-L2 upregulation: An imperfect viral immune evasion mechanism [PDF]

open access: yes, 2018
Viruses often subvert antiviral immune responses by taking advantage of inhibitory immune signaling. We investigated if hantaviruses use this strategy.

Immunological backbone of uveal melanoma: is there a rationale for immunotherapy? [PDF]

open access: yes, 2019
No standard treatment has been established for metastatic uveal melanoma (mUM). Immunotherapy is commonly used for this disease even though UM has not been included in phase III clinical trials with checkpoint inhibitors.
