Datasheet & COA

Antibody FAQs

Description

This recombinant monoclonal antibody is developed as a research-grade biosimilar to Solnerstotug, targeting VSIR (V-Set Immunoregulatory Receptor), also known as VISTA or PD-1H. VSIR functions as an immune checkpoint protein predominantly expressed on myeloid cells and T lymphocytes, where it delivers inhibitory signals that suppress T cell activation and proliferation. This immunoregulatory molecule plays a critical role in maintaining immune homeostasis and self-tolerance. VSIR has emerged as a significant target in immuno-oncology research, as its expression in the tumor microenvironment contributes to immune evasion mechanisms in various cancers, including melanoma, ovarian cancer, and hematological malignancies.

Solnerstotug represents a clinical-stage therapeutic antibody designed to block VSIR-mediated immunosuppression, thereby enhancing anti-tumor immune responses. This biosimilar antibody provides researchers with a valuable tool for investigating VSIR biology, exploring immune checkpoint mechanisms, and developing novel immunotherapeutic strategies. It supports studies examining T cell regulation, myeloid cell function, and tumor immunity, making it particularly relevant for cancer immunology and autoimmune disease research.

Target Background

Function(From Uniprot)

Immunoregulatory receptor which inhibits the T-cell response. May promote differentiation of embryonic stem cells, by inhibiting BMP4 signaling. May stimulate MMP14-mediated MMP2 activation.

Gene References into Functions

Data indicate that VISTA is predominantly expressed and up-regulated in the high-density infiltrated immune cells but minimal in pancreatic cancerous cells. PMID:29771768
High VISTA expression is associated with colorectal carcinoma. PMID:30128738
VISTA expression supports immune-complex inflammation in collagen antibody-induced arthritis and VISTA is expressed in human synovium PMID:29216931
This study is the first to describe the expression of VISTA-expressing lymphocytes in melanoma samples and in the context of acquired resistance to immune checkpoint inhibitors PMID:28776578
Taken together, the results indicated that the VISTA high and CD8 low group, as an immunosuppressive subgroup, might be associated with a poor prognosis in primary OSCC. These findings indicated that VISTA might be a potential immunotherapeutic target in OSCC treatment. PMID:28236118
this review describes the functions of VISTA in the context of cancer immunotherapy PMID:28258694
overexpression of the newly described co-stimulatory molecule, PD1 homologue (PD-1H) in human monocyte/macrophages is sufficient to induce spontaneous secretion of multiple cytokines. PMID:25279955
p53-induced expression of DD1alpha prevents persistence of cell corpses and ensures efficient generation of precise immune responses in mice. PMID:26228159
Results suggest that GI24 contributes to tumor-invasive growth in the collagen matrix by augmenting cell surface MT1-MMP. PMID:20666777
