| intratracheal exposure of common marmosets to mers-cov jordan-n3/2012 or mers-cov emc/2012 isolates does not result in lethal disease. | middle east respiratory syndrome coronavirus (mers-cov) continues to be a threat to human health in the middle east. development of countermeasures is ongoing; however, an animal model that faithfully recapitulates human disease has yet to be defined. a recent study indicated that inoculation of common marmosets resulted in inconsistent lethality. based on these data we sought to compare two isolates of mers-cov. we followed disease progression in common marmosets after intratracheal exposure wi ... | 2015 | 26342468 |
| middle east respiratory syndrome coronavirus efficiently infects human primary t lymphocytes and activates the extrinsic and intrinsic apoptosis pathways. | middle east respiratory syndrome (mers) is associated with a mortality rate of >35%. we previously showed that mers coronavirus (mers-cov) could infect human macrophages and dendritic cells and induce cytokine dysregulation. here, we further investigated the interplay between human primary t cells and mers-cov in disease pathogenesis. importantly, our results suggested that mers-cov efficiently infected t cells from the peripheral blood and from human lymphoid organs, including the spleen and th ... | 2016 | 26203058 |
| occurrence of hemotropic mycoplasmas in non-human primates (alouatta caraya, sapajus nigritus and callithrix jacchus) of southern brazil. | hemoplasmas, the erythrocyte-associated mycoplasmas, have been detected in several primates, causing mostly subclinical infection. this study aimed to determine the prevalence of hemoplasma infection in captive and free-ranging monkeys from southern brazil, as well as factors and hematological abnormalities associated with infection. blood samples from 40 non-human primates (nhp) were tested for hemoplasmas and coinfections. an overall of 10/40 (25.0%) nhp tested positive for hemoplasmas using p ... | 2017 | 28673463 |
| identification and characterization of a subtelomeric satellite dna in callitrichini monkeys. | repetitive dnas are abundant fast-evolving components of eukaryotic genomes, which often possess important structural and functional roles. despite their ubiquity, repetitive dnas are poorly studied when compared with the genic fraction of genomes. here, we took advantage of the availability of the sequenced genome of the common marmoset callithrix jacchus to assess its satellite dnas (satdnas) and their distribution in callitrichini. after clustering analysis of all reads and comparisons by sim ... | 2017 | 28854689 |
| thorny ganglion cells in marmoset retina: morphological and neurochemical characterization with antibodies against calretinin. | in primates over 17 morphological types of retinal ganglion cell have been distinguished by their dendritic morphology and stratification, but reliable markers for specific ganglion cell populations are still rare. the calcium binding protein calretinin is known to be expressed in the inner nuclear and the ganglion cell layer of marmoset retina, however, the specific cell type(s) expressing calretinin in the ganglion cell layer are yet to be determined. here we identified calretinin positive ret ... | 2017 | 28875500 |
| silencing of fus in the common marmoset (callithrix jacchus) brain via stereotaxic injection of an adeno-associated virus encoding shrna. | fused in sarcoma (fus) is an rna binding protein that is involved in frontotemporal lobar degeneration (ftld) and amyotrophic lateral sclerosis (als). to establish the common marmoset (callithrix jacchus) as a model for ftld, we generated a stereotaxic injection-based marmoset model of fus-silencing. we designed shrnas against the marmoset fus gene and generated an aav9 virus encoding the most effective shrna against fus (shfus). the aav encoding shfus (aav-shfus) was introduced into the frontal ... | 2017 | 28842245 |
| different methods for volatile sampling in mammals. | previous studies showed that olfactory cues are important for mammalian communication. however, many specific compounds that convey information between conspecifics are still unknown. to understand mechanisms and functions of olfactory cues, olfactory signals such as volatile compounds emitted from individuals need to be assessed. sampling of animals with and without scent glands was typically conducted using cotton swabs rubbed over the skin or fur and analysed by gas chromatography-mass spectr ... | 2017 | 28841690 |
