| combining in vivo and organotypic in vitro approaches to assess the human relevance of basimglurant (rg7090), a potential car activator. | basimglurant (rg7090), a small molecule under development to treat certain forms of depression, demonstrated foci of altered hepatocytes in a long-term rodent-toxicity study. additional evidence pointed toward the activation of the constitutive androstane receptor (car), an established promoter of nongenotoxic and rodent-specific hepatic tumors. this mode of action and the potential human relevance was explored in vivo using rodent and cynomolgus monkey models and in vitro using murine and human ... | 2020 | 32458970 |
| distinct spatiotemporal mechanisms underlie extra-classical receptive field modulation in macaque v1 microcircuits. | complex scene perception depends upon the interaction between signals from the classical receptive field (crf) and the extra-classical receptive field (ecrf) in primary visual cortex (v1) neurons. although much is known about v1 ecrf properties, we do not yet know how the underlying mechanisms map onto the cortical microcircuit. we probed the spatio-temporal dynamics of ecrf modulation using a reverse correlation paradigm, and found three principal ecrf mechanisms: tuned-facilitation, untuned-su ... | 2020 | 32458798 |
| development of cdx-527: a bispecific antibody combining pd-1 blockade and cd27 costimulation for cancer immunotherapy. | cd27 is a costimulatory molecule that provides a complementary target to the pd-1/pd-l1 checkpoint axis on t cells. combining a cd27 agonist antibody with pd-1/pd-l1 blockade has shown synergistic antitumor activity in preclinical models, which led to clinical studies of the combination in cancer patients. we theorized that coupling cd27 costimulation with pd-1/pd-l1 blockade in a bispecific antibody (bsab) may provide greater immune activating properties than combining the individual mabs due t ... | 2020 | 32451681 |
| anti-vascular endothelial growth factor antibody limits vascular leakage and decreases subretinal fibrosis in a cynomolgus monkey choroidal neovascularization model. | this study was conducted to evaluate the effects of anti-vascular endothelial growth factor (vegf) antibody (bevacizumab) on vascular leakage and fibrosis in a monkey choroidal neovascularization (cnv) model. the relationship between fibrotic tissue and subretinal hyper-reflective material (shrm) in optical coherence tomography (oct) images was also investigated. | 2020 | 32445455 |
| characterization of tumour-infiltrating lymphocytes in a tumour rejection cynomolgus macaque model. | immunotherapy has emerged as a promising and effective treatment for cancer, yet the clinical benefit is still variable, in part due to insufficient accumulation of immune effector cells in the tumour microenvironment. better understanding of tumour-infiltrating lymphocytes (tils) from nonhuman primate tumours could provide insights into improving effector cell accumulation in tumour tissues during immunotherapy. here, we characterize tils in a cynomolgus macaque tumour model in which the tumour ... | 2020 | 32439888 |
| assessment of parp-1 distribution in tissues of cynomolgus monkeys. | the poly(adp-ribose) polymerase 1 (parp-1) enzyme has received much attention in the last decade due to its promising role in cancer therapeutics. despite the expanding use of parp inhibitors in cancer therapy, little is known about parp-1 tissue distribution. our study provides a detailed survey of parp-1 tissue and cellular distribution using well-preserved cynomolgus monkey organs and a well-characterized, highly specific monoclonal parp-1 antibody. overall, parp-1 was detected in most organs ... | 2020 | 32436762 |
| mait cells are functionally impaired in a mauritian cynomolgus macaque model of siv and mtb co-infection. | mucosal-associated invariant t (mait) cells can recognize and respond to some bacterially infected cells. several in vitro and in vivo models of mycobacterium tuberculosis (mtb) infection suggest that mait cells can contribute to control of mtb, but these studies are often cross-sectional and use peripheral blood cells. whether mait cells are recruited to mtb-affected granulomas and lymph nodes (lns) during early mtb infection and what purpose they might serve there is less well understood. furt ... | 2020 | 32433713 |
| diazoxide preconditioning of nonhuman primate pancreas improves islet isolation outcomes by mitochondrial protection. | previously, we showed that diazoxide (dz), an effective ischemic preconditioning agent, protected rodent pancreas against ischemia-reperfusion injury. here, we further investigate whether dz supplementation to university of wisconsin (uw) solution during pancreas procurement and islet isolation has similar cytoprotection in a preclinical nonhuman primate model. | 2020 | 32433410 |
| in vitro and in vivo interspecies chimera assay using early pig embryos. | chimeric pigs harboring organs derived from human stem cells are promising for patient-specific regenerative therapies. induced pluripotent stem cells (ipscs) can contribute to all cell types of the fetus, including germline after injection into embryos. however, ethical concerns prohibit testing human ipscs in chimera assays. here, we evaluated porcine embryos as hosts for an interspecies chimera assay using ipscs from either cynomolgus monkeys (cyipscs) or mouse (mipscs). to establish an in vi ... | 2020 | 32429746 |
