Furthermore, we show that VISTA.COMP, but not VISTA-Fc, functions as an immunosuppressive agonist in vivo capable of prolonging the survival of skin allografts in a mouse transplant model as well as rescuing mice from acute concanavalin-A–induced hepatitis.

In contrast to VISTA-Fc, VISTA.COMP does not require immobilization to inhibit the proliferation of CD4+ T cells undergoing polyclonal activation. Herein, we have designed a stable pentameric VISTA construct (VISTA.COMP) by genetically fusing its IgV domain to the pentamerization domain from the cartilage oligomeric matrix protein (COMP).

However, this effect required its immobilization on a solid surface, suggesting that VISTA-Fc may display limited efficacy as a VISTA-receptor agonist in vivo.

A dimeric construct of the IgV domain of VISTA (VISTA-Fc) was shown to suppress the activation of T cells in vitro. The therapeutic potential of activating this immune checkpoint pathway to reduce inflammatory responses remains untapped, largely due to the inability to derive agonists targeting its unknown receptor. 148556).V-domain immunoglobulin suppressor of T cell activation (VISTA) is a recently discovered immune checkpoint ligand that functions to suppress T cell activity. Canadian Institutes of Health Research (no. Among germline TP53 mutation carriers, increased residual transcriptional activity is correlated with prolonged lifetime cancer survival and delayed tumor onset, and males are more prone to develop brain and gastric tumors. The retention of mutant p53 transcriptional activity prognosticates superior survival for men with glioma and gastric adenocarcinoma harboring sporadic TP53 mutations. The correlation between mutant p53 residual activity with survival was recapitulated in the dataset of germline TP53 mutation carriers (HR = 3.0, 95% CI, 2.7–3.4, P < 0.001 HR = 2.2, 95% CI, 1.8–2.6, P < 0.001 ), where brain and gastric tumors were more common among males (P < 0.001 and P = 0.001, respectively). Male glioma and gastric cancer patients with TP53 mutations resulting in >5% transcriptional activity had 3.1-fold (95% CI, 2.4–3.8 P = 0.002 multivariate analysis hazard ratio ) and 4.6-fold (95% CI, 3.7–5.6 P = 0.001 multivariate analysis HR) lower risk of death as compared with patients harboring inactive (0% activity) p53 mutants. Pan-cancer survival analyses revealed a strong association between increased mutant p53 residual activity and improved survival in males with glioma and gastric adenocarcinoma (P = 0.002 and P = 0.02) that was not present in the female cohorts (P = 0.16 and P = 0.50). Survival was projected by stratifying patients according to their p53 mutant–specific residual transcriptional activity scores. This retrospective cohort analysis included 2,074 patients with sporadic TP53 mutations (403 unique mutations) and 1,049 germline TP53 mutation carriers (188 unique mutations). The objective of this study was to determine whether these biological differences have clinical significance. There is currently no clinical distinction between different TP53 mutations, despite increasing evidence that not all mutations have equally deleterious effects on the activity of the encoded tumor suppressor protein p53.
