https://www.selleckchem.com/peptide/gsmtx4.html We recently reported that tumor necrosis factor (TNF) signaling via the TNFR1 and TNFR2 receptors mediates the effects of long-term exercise on locomotion, cognition and anxiety, but not depressive-like behavior. We now investigated whether the TNF signaling via its receptors also mediates the effects of short-term exercise on cognition, anxiety and depressive-like behaviors. Thirteen-month-old C57BL/6 (WT), TNF , TNFR1 , and TNFR2 mice were provided with 4 weeks of voluntary wheel running followed by behavioral testing using an established behavioral battery. Each genotype had a respective non-exercise control. There was no interaction between genotype and exercise in any of the tests but the main effect of genotype, and not exercise, were found to be significant in the open field (OF), forced-swim test (FST) and Barnes maze (BM). In the OF, the control and exercise TNFR2 mice spent significantly less time in the inner zone than mice in the control and exercise WT and TNF cohorts. In the FST, ctly, it does not mediate the effects of short-term exercise on these behaviors in middle-aged mice.Oxytocin (OT) is a nanopeptide released into systemic circulation via the posterior pituitary (peripheral) and into the central nervous system via widespread OTergic pathways (central). Central OT plays a significant role in variety of functions from social and executive cognition to immune regulation. Many ongoing studies explore its therapeutic potential for variety of neuropsychiatric disorders. Measures of peripheral OT levels are most frequently used as an indicator of its concentration in the central nervous system in humans and animal models. In this study, LC-MS/MS was used to measure OT in pituitary samples collected from adult male macaque monkeys in order to explore the correlation between individual levels of OT in the CSF (central) and pituitary (peripheral). We quantified individual differences in the levels of OT in
