Their utilization in non-human primates (NHPs) is however limited and their efficacy still debated. Here, we recorded and examined the neuronal activity in the hM4Di DREADD-transduced and hM4Di DREADD-free GPe of two anesthetized animals following local intra-GPe microinjection of clozapine-N-oxide (CNO). Our results revealed that the neuronal activity of the well-isolated units recorded in the hM4Di DREADD-transduced GPe exhibited diverse patterns in timing and polarity (increase/decrease) of firing rate modulations following CNO injection. Nevertheless, significant decreases in activity were more frequent (and more pronounced) than significant increases in activity during CNO injection (6/18 vs. 3/18 units), and were exclusive after CNO Injection (8/18 units). In contrast, only one of the 8 well-isolated units recorded in hM4Di DREADD-free GPe exhibited a significant increase in activity after CNO injection. Overall, the number of units exhibiting a significant period-related decrease following CNO injection were significantly larger in hM4Di DREADD-transduced GPe than in the hM4Di DREADD-free GPe [8/18 (44.4%) vs. 0/8 (0%)]. Moreover, post-mortem histochemical analysis revealed that hM4Di DREADDs were expressed at high level in the GPe neurons located in the vicinity of the viral vector injection sites. Our results therefore show in vivo hM4Di DREADD-based inhibition of pallidal neurons in the NHP model and reinforce the view that DREADD technology can be effective in NHPs.

We sought to assess the effects of intermittent PTH 1-34 administration on bone angiogenesis, bone marrow blood vessel redistribution, and matrix metalloproteinase-9 as a function of advancing age in mice. What is the main finding and its importance? Short-term (i.e., 10 days) intermittent PTH 1-34 administration increased the number of small (≤ 29μm) bone marrow blood vessels and augmented matrix metalloproteinase-9. These changes occurred prior to alterations in trabecular bone. Given the rapid response in bone angiogenesis, this investigation highlights the impact of intermittent PTH administration on the bone vascular network. selleck chemicals ABSTRACT Intermittent parathyroid hormone (PTH) administration augments bone, stimulates the production of matrix metalloproteinase (MMP)-9, and relocates bone marrow blood vessels closer to osteoid seams. Discrepancies exist, however, regarding bone angiogenesis. Since MMP-9 participates in cellular homing and migration, it med blood vessels was higher (p less then 0.05) and tended (p = 0.055) to be higher, respectively, in 10dPTH vs. 5dPTH and CON. MMP-9 was augmented (p less then 0.05) in 10dPTH vs. the other groups. MMP-9 was closer (p less then 0.05) to 1-29 μm blood vessels and furthest (p less then 0.05) from bone. In conclusion, bone angiogenesis occurred by day 10 of intermittent PTH administration, coinciding with augmented MMP-9 secretion near the smallest (1-29 μm) blood vessels.
