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.

Current trends in glioblastoma multiforme treatment: radiation therapy and immune checkpoint inhibitors. [PDF]

open access: yes, 2013
Glioblastoma multiforme (GBM) is the most common primary brain cancer. Even with aggressive combination therapy, the median life expectancy for patients with GBM remains approximately 14 months.

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.

Expression of the costimulatory molecule B7-H3 is associated with prolonged survival in human pancreatic cancer [PDF]

open access: yes, 2009
Background Costimulatory signaling has been implicated as a potential regulator of antitumor immunity in various human cancers. In contrast to the negative prognostic value of aberrant B7-H1 expression by pancreatic cancer cells, the role of B7-H3 is ...

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.

Differential inflammatory response to Helicobacter pylori infection: etiology and clinical outcomes [PDF]

open access: yes, 2015
The bacterial pathogen Helicobacter pylori commonly colonizes the human gastric mucosa during early childhood and persists throughout life. The organism has evolved multiple mechanisms for evading clearance by the immune system and, despite inducing ...

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).

Immune checkpoint inhibitors in renal cell carcinoma [PDF]

open access: yes, 2017
The immune system has long been known to play a critical role in the body's defence against cancer, and there have been multiple attempts to harness it for therapeutic gain.
