Zika virus (ZIKV) is primarily transmitted to humans through mosquito bites or sexual contact. The excretion and persistence of contagious ZIKV in various body fluids have been well documented in ZIKV patients; however, the risk of direct contact exposure remains unclear. Here, we show that guinea pigs are susceptible to ZIKV infection via subcutaneous inoculation route; infected guinea pigs exhibit seroconversion and significant viral secretion in sera, saliva, and tears. Notably, ZIKV is efficiently transmitted from infected guinea pigs to naïve co-caged animals...

Perturbation of OAT1- and OAT3-mediated transport can alter the exposure, efficacy, and safety of drugs. Although these have been reports of the endogenous biomarkers for OAT1/3, none of these have all of the characteristics required for a clinical useful biomarker. Cynomolgus monkeys were treated with intravenous probenecid (PROB) at a dose of 40 mg/kg in this study. As expected, PROB increased the AUC of co-administered furosemide (FSM), a known substrate of OAT1 and OAT3, by 4.1-fold, consistent with the values reported in humans (3...

Although avian paramyxovirus type 1 is known to cause mild transient conjunctivitis in human beings, there are two recent reports of fatal respiratory disease in immunocompromised human patients infected with the pigeon lineage of the virus (PPMV-1). In order to evaluate the potential of PPMV-1 to cause respiratory tract disease, we inoculated a PPMV-1 isolate (hPPMV-1/Netherlands/579/2003) from an immunocompromised human patient into three healthy cynomolgus macaques (Macaca fascicularis) and examined them by clinical, virological, and pathological assays...

The cellular composition of brains shows largely conserved, gradual evolutionary trends between species. In the primate spinal cord, however, the glia-neuron ratio was reported to be greatly increased over that in the rodent spinal cord. Here, we re-examined the cellular composition of the spinal cord of one human and one non-human primate species by employing two different counting methods, the isotropic fractionator and stereology. We also determined whether segmental differences in cellular composition, possibly reflecting increased fine motor control of the upper extremities, may explain a sharply increased glia-neuron ratio in primates...

MHC-E is a highly conserved nonclassical MHC class Ib molecule that predominantly binds and presents MHC class Ia leader sequence-derived peptides for NK cell regulation. However, MHC-E also binds pathogen-derived peptide Ags for presentation to CD8(+) T cells. Given this role in adaptive immunity and its highly monomorphic nature in the human population, HLA-E is an attractive target for novel vaccine and immunotherapeutic modalities. Development of HLA-E-targeted therapies will require a physiologically relevant animal model that recapitulates HLA-E-restricted T cell biology...

Domoic acid (DA), a neurotoxin, is produced by marine algae and has caused toxications worldwide in animals and humans. However, the toxicokinetics of DA has not been fully evaluated, and information is missing on the disposition of DA following oral exposures at doses that are considered safe for human consumption. In this study, toxicokinetics of DA were investigated in cynomolgus monkeys, following single doses of 5 µg/kg DA iv, 0.075 mg/kg DA po and 0.15 mg/kg DA po. Following iv dosing, DA had a systemic clearance of 124 ± 71 ml/hr/kg, volume of distribution at steady state of 131±71 ml/kg and elimination half-life of 1...

Objectives: Extremely multiresistant strains of Enterobacteriaceae, such as those of Escherichia coli and Klebsiella pneumoniae, are emerging and spreading at a worrisome speed. Polymyxins (polymyxin B, colistin) are used as last-line therapy against such strains, in spite of their notable nephrotoxicity that may even require discontinuation of the therapy. We have previously developed polymyxin derivatives NAB739 and NAB815 that are better tolerated in cynomolgus monkeys than polymyxin B and are, in contrast to polymyxin B, excreted in the cynomolgus urine to a very significant degree...

Hematologically-derived tumors make up ~10% of all newly-diagnosed cancer cases in the U.S. Of these, the non-Hodgkin lymphoma (NHL) designation describes a diverse group of cancers that collectively rank among the top 10 most commonly diagnosed cancers worldwide. Although long-term survival trends are improving, there remains a significant unmet clinical need for treatments to help patients with relapsed or refractory disease, one cause of which is drug efflux through upregulation of xenobiotic pumps, such as MDR1...

Experimental autoimmune encephalomyelitis (EAE) induced by self-myelin antigen is a widely used multiple sclerosis (MS) model for preclinical studies of new therapeutics and potential pathogenesis. By comparison with rodent EAE models, EAE models in primates are more similar to MS. Some groups have developed EAE models in primates by using common marmoset (Callithrix jacchus). However, this model has some limitations. EAE in cynomolgus monkey (Macaque fasciculrais) could overcome these limitations. In this study, EAE was induced in cynomolgus monkey by immunizing with the recombinant human myelin oligodendrocyte glycoprotein extracellular domain (1-125) (rhMOG1-125) and a synthetic peptide, representing peptide 34-56 of human myelin oligodendrocyte glycoprotein (MOG34-56) in complete Freund's adjuvant (CFA) and in combination with intravenous injection of pertussis toxin, and subsequent booster immunizations with the same dose of antigen in incomplete Freund's adjuvant (IFA) until the animals developed clinically significant EAE (score≥2)...

Cynomolgus monkeys have been widely used for the prediction of drug absorption in humans. The purpose of this study was to clarify the regional protein expression levels of cytochromes P450 (CYPs), UDP-glucuronosyltransferases (UGTs), and transporters in small intestine of cynomolgus monkey using liquid chromatography-tandem mass spectrometry, and to compare them with the corresponding levels in human.

Plague has led to millions of deaths in history and outbreaks continue to the present day. The efficacy limitations and safety concerns of the existing killed whole cell and live-attenuated vaccines call for the development of new vaccines. In this study, we evaluated the immunogenicity and safety of a novel subunit plague vaccine, comprising native F1 antigen and recombinant V antigen. The cynomolgus macaques in low- and high-dose vaccine groups were vaccinated at weeks 0, 2, 4 and 6, at dose levels of 15 μg F1 + 15 μg rV and 30 μg F1 + 30 μg rV respectively...

Pig-tailed macaques (Macaca nemestrina, Mane) are important models for human immunodeficiency virus (HIV) studies. Their infectability with minimally modified HIV makes them a uniquely valuable animal model to mimic human infection with HIV and progression to acquired immunodeficiency syndrome (AIDS). However, variation in the pig-tailed macaque major histocompatibility complex (MHC) and the impact of individual transcripts on the pathogenesis of HIV and other infectious diseases is understudied compared to that of rhesus and cynomolgus macaques...

INTRODUCTION: Depressive symptoms (DS) in humans are associated with decreased resting state vagal activity, but sex seems to moderate this association. Recently, in human females DS have been associated with greater or similar cardiac vagal activity compared to men in both, clinical and non-clinical samples. A previously validated animal model of behavioral depression was used in the present study to investigate the association of DS and cardiac vagal activity in non-human primates. METHODS: The root mean square of successive differences between adjacent heart beats (RMSSD) was used as an indicator of vagally-mediated heart rate variability in 24h heart rate recordings collected via telemetry in 42 adult female cynomolgus monkeys (Macaca fascicularis)...

Allogeneic hematopoietic stem cell transplantation (HSCT) is a critically important therapy for hematological malignancies, inborn errors of metabolism, and immunodeficiency disorders, yet complications such as graft-vs.-host disease (GvHD) limit survival. Development of anti-GvHD therapies that do not adversely affect susceptibility to infection or graft-vs.-tumor immunity are hampered by the lack of a physiologically relevant, preclinical model of allogeneic HSCT. Here we show a spectrum of diverse clinical HSCT outcomes including primary and secondary graft failure, lethal GvHD, and stable, disease-free full donor engraftment using reduced intensity conditioning and mobilized peripheral blood HSCT in unrelated, fully MHC-matched Mauritian-origin cynomolgus macaques...

A case of bilateral superior canine tooth pulp necrosis in an 18-year-old male Macaca fascicularis is described . A skull computed tomography scan was performed to confirm the diagnostic suspicion. A successful bilateral endodontic treatment with coronotomy was performed using rotary nickel-titanium instruments. Post-operative dental radiographs confirmed the correct positioning of the sealant. A rapid and excellent clinical recovery was obtained after each surgery. This innovative approach may contribute to improving the quality of root canal treatments provided to non-human primates...

Existing models of Ebola virus disease (EVD) suggest antigen-presenting cells are initial targets of Zaire ebolavirus (ZEBOV). In vitro studies have shown that ZEBOV infection of monocytes and macrophages results in the production of inflammatory mediators, which may cause lymphocyte apoptosis. However, these findings have not been corroborated by in vivo studies. In this study, we report the first longitudinal analysis of transcriptional changes in purified monocytes, T-cells, and B-cells isolated from cynomolgus macaques following infection with ZEBOV-Makona...

AZD8848 is a TLR7 agonist antedrug developed for administration by inhalation dosing for the treatment of allergic diseases, such as asthma. Allergic asthma is associated with increased levels of Th2 cytokines which are suppressed for extended periods by TLR7 agonists in a number of preclinical models of allergic airway inflammation. However, TLRs form a central part of innate immunity and their activation often results in proinflammatory responses. Whilst AZD8848's antedrug mechanism is designed to restrict its pharmacological action beyond the lung, the effect of chronic, supramaximal dosing to the target tissue has yet to be defined...

BACKGROUND: The treatments currently approved for Duchenne muscular dystrophy (DMD), a progressive skeletal muscle wasting disease, address the needs of only a small proportion of patients resulting in an urgent need for therapies that benefit all patients regardless of the underlying mutation. Myostatin is a member of the transforming growth factor-β (TGF-β) family of ligands and is a negative regulator of skeletal muscle mass. Loss of myostatin has been shown to increase muscle mass and improve muscle function in both normal and dystrophic mice...

AIMS/HYPOTHESIS: Glucagon like peptide-1 (GLP-1) enhances glucose-dependent insulin secretion by binding to GLP-1 receptors (GLP1Rs) on pancreatic beta cells. GLP-1 mimetics are used in the clinic for the treatment of type 2 diabetes, but despite their therapeutic success, several clinical effects of GLP-1 remain unexplained at a mechanistic level, particularly in extrapancreatic tissues. The aim of this study was to generate and characterise a monoclonal antagonistic antibody for the GLP1R for use in vivo...
