In vivo depletion of DC impairs the anti‐tumor effect of agonistic anti‐CD137 mAb

Anti-CD137 mAb are capable of inducing tumor rejection in several syngeneic murine tumor models and are undergoing clinical trials for cancer. The anti-tumor effect involves costimulation of tumor-specific CD8 1 T cells. Whether antigen cross-presenting DC are required for the efficacy of anti-CD137 mAb treatment has never been examined. Here we show that the administration of anti-CD137 mAb eradicates EG7-OVA tumors by a strictly CD8b 1 T-celldependent mechanism that correlates with increased CTL activity. Ex vivo analyses to determine the identity of the draining lymph node cell type responsible for tumor antigen crosspresentation revealed that CD11c 1 cells, most likely DC, are the main players in this tumor model. A minute number of tumor cells, revealed by the presence of OVA cDNA, reach tumordraining lymph nodes. Direct antigen presentation by tumor cells themselves also participates in anti-OVA CTL induction. Using CD11c diphtheria toxin receptor-green fluorescent protein-C57BL/6 BM chimeric mice, which allow for sustained ablation of DC with diphtheria toxin, we confirmed the involvement of DC in tumor antigen cross-presentation in CTL induction against OVA [257][258][259][260][261][262][263][264] epitope and in the antitumor efficacy induced by anti-CD137 mAb.Key words: CD137 (4-1BB) . Cross-priming . CTL . DC . Tumor immunity Supporting Information available online Introduction CD137, also known as 4-1BB, is a TNF-receptor family costimulatory molecule originally identified on activated T cells [1]. Its natural ligand CD137L is found on APC, including B cells, macrophages, and DC [2]. In the presence of TCR engagement, signaling through CD137 leads to increased T-cell proliferation, cytokine production, and prolonged CD8 1 T-cell survival in vitro [2]. Administration of agonistic anti-CD137 mAb either alone or following peptide vaccination is capable of inducing the eradication of established tumors in several transplantable tumor models [3,4]. This anti-tumor effect is dependent on CD8 1 T cells that show increases in tumor-specific cytotoxic activity and associated IFN-g production [3,4]. Recent studies have demonstrated that the activity of anti-CD137 mAb treatment is also dependent on their ability to enhance the survival of CD8 1 CTL, and on the prevention/reversal of established anergy [5][6][7]. In addition, antigen-independent anti-CD137 mAb effects have been described for memory T cells, and CD137 seems to be an Ã These authors contributed equally to this work.ÃÃ These authors share equal senior authorship. 2424important player in the differentiation of memory cells [8][9][10].

“…3 It is of particular interest that several markers have been characterized that show a specific expression in tumor-associated endothelial cells, but not in normal endothelial cells. 2,4,5 One such molecule, that shows high expression in the tumor-associated neovasculature is prostate-specific membrane antigen (PSMA, also known as folate hydrolase 1, FOLH1). PSMA is a metallo-protease that was originally cloned from human prostate carcinoma cells and has been shown to be overexpressed in the vast majority of prostate cancers.…”

High expression of prostate-specific membrane antigen in the tumor-associated neo-vasculature is associated with worse prognosis in squamous cell carcinoma of the oral cavity

Prostate-specific membrane antigen (PSMA) is a transmembrane protein expressed in prostate cancer as well as in the neo-vasculature of nonprostatic solid tumors. Here, we determined the expression pattern of PSMA in the vasculature of oral squamous cell carcinoma. Using a previously validated antibody, PSMA staining distribution and cyclooxygenase 2 (COX2) expression status was evaluated in a cohort of patients with squamous cell carcinoma of the oral cavity (n ¼ 96) using immunohistochemistry and was correlated with clinicopathological features as well as outcome. Twenty-four (25%) cases showed no detectable PSMA staining, 48 (50%) demonstrated positive immunoreactivity for PSMA in less than 50% of microvessels and 24 (25%) cases showed strong endothelial PSMA expression in more than 50% of tumor-associated microvessels. High endothelial PSMA expression was associated with greatly reduced survival (18.2 vs 77.3 months; P ¼ 0.0001) and maintained prognostic significance after adjusting for grade and stage in multivariate analysis (hazard ratio ¼ 2.19, P ¼ 0.007). Furthermore, we observed a strong association between endothelial PSMA and cancer cell-specific COX2 expression. In conclusion, we provide the first evidence for the prognostic significance of endothelial PSMA expression in oral squamous cell carcinoma and, suggest a potential interaction between arachidonic acid metabolites and endothelial PSMA expression in the tumor neo-vasculature.

“…While CD146 has been found to be widely expressed in adult normal vascular endothelium through gene expression profiling and using various anti-CD146 antibodies, for example the s-Endo-1 or the P1H12 antibodies, the AA98 mouse anti-human CD146 antibody developed in Yan's laboratory appears to preferentially label CD146 on tumor-associated endothelium compared to normal endothelium [9,10]. AA98, which binds the same region of CD146 as netrin-1, prevents dimerization of the receptor [7,11].…”
