Helicobacter pylori cag pathogenicity island's role in B7-H1 induction and immune evasion. [PDF]

, 2015
During Helicobacter pylori (H. pylori) infection CD4+ T cells in the gastric lamina propria are hyporesponsive and polarized by Th1/Th17 cell responses controlled by Treg cells. We have previously shown that H. pylori upregulates B7-H1 expression on GEC,

Overexpression of B7-H1 significantly associates with tumor grade and postoperative prognosis in human urothelial cancers [PDF]

, 2007
熊本大学博士（医学）The programmed death-1 (PD-1)/B7-H1 (also called PD-L1) pathway negatively regulates T-cell activation and has been suggested to play an important role in regulating antitumor host immunity.

B7-H1 Determines Accumulation and Deletion of Intrahepatic CD8+ T Lymphocytes [PDF]

, 2004
Upon systemic activation by antigens, CD8+, but not CD4+, T cells selectively accumulate and undergo apoptosis in the liver, a mechanism associated with the induction of hepatic tolerance and chronic infection.

B7-H1 Overexpression Regulates Epithelial–Mesenchymal Transition and Accelerates Carcinogenesis in Skin

, 2011
B7-H1 (CD274) is a T-cell coinhibitory molecule that is also often induced on human carcinoma cells, where its expression has been implicated in immune escape.

The role of B7-H1 in immunotherapy of pancreatic cancer in the murine Panc02 model

, 2020
Pancreatic ductal adenocarcinoma (PDA) is a quite frequent, hardly treatable and usually terminal neoplasia. Therefore, new approaches in cancer-immunotherapy are currently being searched for.

Tumor-expressed B7-H1 and B7-DC in relation to PD-1+ T-cell infiltration and survival of patients with cervical carcinoma

, 2009
PURPOSE: The interaction between programmed cell death 1 (PD-1), expressed by activated effector or regulatory T cells, and B7-H1 (PD-L1) and B7-DC (PD-L2) results in the inhibition of T-cell function. The aim of this study was to determine B7-H1, B7-DC,

Recognition of PG by NOD1 causes induction of B7-H1 expression by GEC.

, 2015
(A) B7-H1 mRNA expression was analyzed using real-time quantitative RT-PCR in AGS cells. RNA was isolated from untreated and 2-h iEDAP (dipeptide present in PG) treated (10 μg/mL) cells.
