VISTA (protein)

(Redirected from C10orf54)

V-domain Ig suppressor of T cell activation (VISTA) is a type I transmembrane protein that functions as an immune checkpoint and is encoded by the VSIR gene.[5][6][7]

Structure and function

edit

VISTA is approximately 50 kDa and belongs to the immunoglobulin superfamily and has one IgV domain.[8][5]

VISTA is part of the B7 family, is primarily expressed in white blood cells and its transcription is partially controlled by p53.[8][9] There is evidence that VISTA can act as both a ligand[10] and a receptor[11] on T cells to inhibit T cell effector function and maintain peripheral tolerance.[5][8] Similarly, VISTA and TIM-3 may co-exist on macrophages infiltrating different human and mouse tumours where they can co-regulate immunotherapy resistance.[12]

Clinical significance

edit

VISTA is produced at high levels in tumor-infiltrating lymphocytes, such as myeloid-derived suppressor cells and regulatory T cells, and its blockade with an antibody results in delayed tumor growth in mouse models of melanoma[13] and squamous cell carcinoma.[14] It is also up-regulated in tumour-associated macrophages in various malignancies, including melanoma, especially in immunotherapy-resistant human context.[12]

Monocytes from HIV-infected patients produce higher levels of VISTA compared to uninfected individuals. The increased VISTA levels correlated with an increase in immune activation and a decrease in CD4-positive T cells.[15]

As a drug target

edit

There is an ongoing cancer immunotherapy clinical trial for a monoclonal antibody targeting VISTA in advanced cancer.[16] Preliminary results of the phase I clinical trial show good safety tolerance and anti-cancer activity in patients with advanced tumours.[17] Another ongoing clinical trial involves a small molecule that antagonizes the programmed death-ligands 1 and 2 (PD-L1 and PD-L2), and VISTA pathways in patients with advanced solid tumors or lymphomas.[18]
