Project description:This study mapped the genome wide DNA methylation changes in whole blood and buccal swab samples of 2 year old male rhesus monkeys subjected to parental deprivation in their first months of life (surrogate peer-reared condition). Equal numbers of control mother-reared (MR) and surrogate peer-reared (SPR) male monkeys whole blood (5 vs 5) and buccal swab samples (3 vs 3) were analyzed by methylated DNA immunoprecipitation (MeDIP) coupled with promoter tiling arrays.

Project description:Gene expression profiling was carried out on peripheral blood mononuclear cell mRNA samples collected from 4 mo old rhesus macaques subject to maternal rearing, peer rearing, or surrogate peer rearing. The primary research question is whether gene expression differs as a function of early rearing conditions.

Project description:Sleep deprivation in humans is associated with both cognitive impairment and immune dysregulation. An animal model of neuropathogenesis may provide insight to understand the effects of sleep deprivation on the brain. Human neurocognition is more closely mirrored by nonhuman primates (NHP) than other animals. As such, we developed an NHP model to assess the impact of sleep deprivation on neurocognition and markers of systemic immune activation. Six male rhesus macaques underwent three rounds of sleep deprivation (48 h without sleep) at days 0, 14, and 28. We performed domain specific cognitive assessments using the Cambridge Neuropsychological Test Automated Battery (CANTAB) via a touch screen before and after 24 and 48 h of sleep deprivation. Immune activation markers were measured in the blood by multiplex assay and flow cytometry. Although we observed variability in cognitive performance between the three rounds of sleep deprivation, cognitive impairments were identified in all six animals. We noted more cognitive impairments after 48 h than after 24 h of sleep deprivation. Following 48 h of sleep deprivation, elevations in markers of immune activation in the blood were observed in most animals. The observed impairments largely normalized after sleep. The co-occurrence of systemic immune alterations and cognitive impairment establishes this model as useful for studying the impact of sleep deprivation on neurobehavior and immune perturbations in rhesus macaques.

Project description:To identify immunodominant antigens that elicit a humoral immune response following a primary genital infection, rhesus monkeys were inoculated cervically with Chlamydia trachomatis serovar D. Serum samples were collected and probed with a protein microarray expressing 864/894 (96.4%) of the open reading frames of the C. trachomatis serovar D genome. The antibody response was analyzed in 72 serum samples from 12 inoculated monkeys. The following criteria were utilized to identify immunodominant antigens: proteins found to be recognized by at least 75% (9/12) of the infected monkeys with at least 15% elevations in normalized signal intensity from week 0 to week 8 post infection. All infected monkeys developed Chlamydia specific serum antibodies. Eight proteins satisfied the selection criteria for immunodominant antigens: CT242 (OmpH-like protein), CT541 (mip), CT681 (ompA), CT381 (artJ), CT443 (omcB), CT119 (incA), CT486 (fliY), and CT110 (groEL). Of these, three antigens, CT119, CT486 and CT381, were not previously identified as immunodominant antigens using non-human primate sera. In conclusion, these immunodominant antigens can now be tested for their ability to identify individuals with a primary C. trachomatis genital infection and to design a vaccine strategy to protect against a primary infection with this pathogen.

Project description:Dietary restriction has shown benefits in physiological, metabolic, and molecular signatures associated with aging. In mice, periodic dietary restriction, that accompanies cyclical periods of reduced calories, mitigates aging phenotypes, yet the effects of this periodic restriction in higher order, genetically heterogenous mammals, have not been investigated. Reducing caloric intake in middle-aged Rhesus Macaques for four days followed by ad libitum eating for ten days, repeated for six cycles, led to significant changes in body composition, metabolome, and microbiome of the restricted monkeys compared to their ad libitum fed (age and sex matched) controls. These changes were also associated with stabilized blood parameters. The changes in metabolome, microbiome, and body compositions were additive, with consistent but increasingly pronounced changes in later cycles, suggesting sustaining benefits in non-human primates. These results suggest this type of cyclical dietary restriction, that is easy to adhere to, will also have translational benefits in humans while enhancing aging-associated parameters.

Project description:Adverse early life experiences are well-established risk factors for neurological disorders later in life. However, the molecular mechanisms underlying the impact of adverse experiences on neurophysiological systems throughout life remain incompletely understood. Previous studies suggest that social attachment to parents in early development are indispensable for infants to grow into healthy adults. In situations where multiple offspring are born in a single birth in common marmosets, human hand-rearing is employed to ensure the survival of the offspring in captivity. However, hand-reared marmosets often exhibit behavioral abnormalities, including abnormal vocalizations, excessive attachment to the caretaker, and aggressive behavior. In this study, comprehensive transcriptome analyses were conducted on hippocampus tissues, a neuroanatomical region sensitive to social attachment, obtained from human hand-reared (N = 6) and parent-reared male marmosets (N = 5) at distinct developmental stages. Our analyses revealed consistent alterations in a subset of genes, including those related to neurodevelopmental diseases, across different developmental stages, indicating their continuous susceptibility to the effects of early parental deprivation. These findings highlight the dynamic nature of gene expression in response to early life experiences and suggest that the impact of early parental deprivation on gene expression may vary across different stages of development.

Project description:A small block of the midbrain containing the dorsal raphe nucleus was obtained from ovariectomized monkeys treated with placebo, estrogen, progesterone or estrogen plus progesterone for one month. The RNA was extracted and hybridized to the Rhesus Affymetrix chip. The results were analyzed with GCOS 1.0 Each chip represents one monkey. N=3 monkeys per treatment.

Project description:Type 2 diabetes mellitus (TM) is a severely metabolic disorder that affects above 10% worldwide population. Obesity is a major cause of insulin resistance and contributes to the development of TM. Liver is an essential metabolic organ that plays crucial roles in the pathogenesis of obesity and diabetes. However, the underlying mechanisms of liver in the transition of obesity to diabetes are not fully understood. Nonhuman primate (NHP) rhesus monkey is an appropriate animal for research of human diseases. Here, we first screened and selected three individual spontaneous and diabetic rhesus monkeys. Interestingly, the diabetic monkeys were obese with high BMI at beginning, but gradually lost their body weight during one-year observation. Furthermore, we performed a SILAC-based quantitative proteomics to identify proteins and signaling pathways with altered expression in the liver of obese and diabetic monkeys. Totally, 3509 proteins were identified and quantified, and of which 185 proteins displayed altered expression level. GO analysis revealed that the expression of proteins involved in fatty acids β-oxidation and galactose metabolism was increased in obese monkeys; while proteins involved in oxidative phosphorylation (OXPHOS) and branched chain amino acid (BCAA) degradation was upregulated in diabetic monkeys. In addition, we observed a mild impaired mitophagy and apoptosis in the liver of diabetic monkeys, suggesting a dysfunction of mitochondria and liver injury in the late onset of diabetics. Taken together, our liver proteomics may reveal a distinct metabolic transition from fatty acids β-oxidation in obese monkey to BCAA degradation in diabetic monkeys.
