"They have a central effect on the weather, on our climate system.
Assuming that ASA could have a central effect on pain related structures as the anterior cingulate cortex, SI or SII as indicated by earlier studies [21, 26], we were especially interested in the responses of these regions to trigeminal-nociceptive stimulation.
For example, recently Lannfelt and colleagues found that PBT2 (a metal-protein attenuating compound) reduced the levels of Aβ42 in CSF, but not plasma, of patients with AD, indicating that the drug had a central effect on Aβ metabolism[27].
The ability of an NSAID to have a central effect through penetration of the blood brain barrier is variable and depends on various molecular characteristics such as size, lipid solubility, and capacity to bind to plasma proteins [ 15].
Although the question of whether plasma GLP-1 can cross an intact blood-brain barrier is controversial [ 4], pre-treatment with supratherapeutic doses of linagliptin, a DPP-4 inhibitor, reduced neuronal loss in a mouse model of stroke [ 11], suggesting that GLP-1 may indeed have a central effect after injury.
Here we demonstrate that IL-7 has a central hypothalamic effect.
On the contrary, the result of the hot-plate test did not show that TFC has a central antinociceptive effect.
Conversely, an overactive ECS has a central orexigenic effect and reduces energy expenditure, promoting lipid deposition in peripheral tissues like the liver and WAT (Cota, 2008).
It has a central analgesic effect with a weak affinity for the μ-opioid receptor and also causes spinal inhibition of the reuptake of noradrenaline and serotonin (Budd 1999; Schnitzer 1999).
