Immune responses must be fine-tuned to allow effective clearance of invading pathogens, while maintain tolerance to self-antigens. T cells are the major effector cells for fighting and killing tumor cells. Immune checkpoints play a pivotal role in T cell activation, and determine the functional outcome of T cell receptor (TCR) signaling. The blockade of immune checkpoints CTLA-4 and PD-1 has already been one of the most successful cancer immunotherapies. In this review, we will focus on three novel inhibitory B7 family checkpoint molecules, B7-H3, B7S1 and VISTA...

The B7-CD28 family of ligands and receptors play important roles in T-cell co-stimulation and co-inhibition. Phylogenetically they can be divided into three groups. The recent discovery of the new molecules (B7-H3 [CD276], B7x [B7-H4/B7S1], and HHLA2 [B7H7/B7-H5]/TMIGD2 [IGPR-1/CD28H]) of the group III has expanded therapeutic possibilities for the treatment of human diseases. In this review, we describe the discovery, structure, and function of B7-H3, B7x, HHLA2, and TMIGD2 in immune regulation. We also discuss their roles in important pathological states such as cancers, autoimmune diseases, transplantation, and infection...

Increasing evidence has demonstrated an association between increased soluble B7-H3 (sB7-H3) levels and unfavorable progression in patients with malignant tumors. In the present study, we detected sB7-H3 levels in serum to investigate the value of sB7-H3 as a tool for differential diagnosis of cirrhotic patients with or without early-stage hepatocellular carcinoma (ESHCC). We also assessed the diagnostic value of sB7-H3regarding the prediction of overall survival (OS) of cirrhotic patients with ESHCC. sB7-H3 expression was measured in 91 healthy volunteers, 149 cirrhotic patients with ESHCC, and 87 cirrhotic patients by ELISA, and correlations between DCP1a level and clinical characteristics were analyzed...

The costimulatory protein B7-H3 has been shown to play a contributory role in the development and progression of experimental pneumococcal meningitis by augmentation of the innate immunity-associated inflammatory response via a TLR2-dependent manner. This study aimed to clarify the component(s) of TLR2-mediated signal transduction pathways responsible for B7-H3-augmented inflammatory response and subsequent brain damage during experimental pneumococcal meningitis. Administration of B7-H3 did not augment expression of TLR2 and other TLR2 upstream components, but led to an enhanced formation of MyD88-IRAK immunocomplex in the brain of S...

B7-H3, a new member of the B7 superfamily, acts as both a T cell costimulator and coinhibitor. Recent studies identified B7-H3 plays a critical role in the development of asthma. But the definitive mechanism is not clear. In this study, we further report that B7-H3 participates in the development of OVA-induced asthma in a murine model. And study its mechanism through the vitro and vivo experiment. Exogenous administration of B7-H3 strongly amplified the inflammatory response and augmented proinflammatory cytokines in vitro and vivo...

OBJECTIVES: Compared with non-smoking counterparts, smoking-associated lung cancers have a higher mutational load, resulting in the creation of more tumor neoantigens and increased immunogenicity. B7-H3 (also known as CD276) belongs to a family of immune modulators that includes PD-1 and PD-L1 (also known as B7-H1 or CD274). Considering the evidence that PD-L1 inhibitors have been shown to be more effective against lung cancer in smokers, we herein examined the prognostic interaction of tumor B7-H3 expression level with smoking history in lung adenocarcinoma patients...

B7-H3 is a glycoprotein overexpressed in cancer, but its functional contribution in this setting remains poorly understood. In the present study, we identified that the overexpression of B7-H3 in lung cancer resulted in aberrant lipid metabolism via SREBP-1/FASN signaling pathway. Immunohistochemical analysis of tissue microarrays revealed that approximately 80.4% (37/46) of lung cancer tissues were positive for B7-H3 accompanying poor prognosis. Notably, Oil red O staining and total triglyceride assay exhibited that down-regulation of B7-H3 decreased lipid synthesis in lung cancer A549 and H446 cell lines...

The co-stimulatory ligands of B7-family have been confirmed to play an important role in negatively regulating the T-cell mediated anti-tumor immunity. In addition, these inhibitory molecules are also aberrantly expressed on various human cancers tissues, and significantly associated with cancer progression and patients' poor prognoses. We have previously reported that B7-H3 and B7-H4 ligands are highly expressed in human esophageal cancer tissues. Herein, we tried to further analyze the value of their combined expression on prognostic prediction for esophageal cancer patients...
