Abstract:
The level of the endocannabinoid anandamide is controlled by fatty acid amide hydrolase (FAAH). In 2011, PF-04457845, an irreversible inhibitor of FAAH, was progressed to phase II clinical trials for osteoarthritic pain. This article discusses a prospective, integrated systems pharmacology model evaluation of FAAH as a target for pain in humans, using physiologically based pharmacokinetic and systems biology approaches. The model integrated physiological compartments; endocannabinoid production, degradation, and disposition data; PF-04457845 pharmacokinetics and pharmacodynamics, and cannabinoid receptor CB1-binding kinetics. The modeling identified clear gaps in our understanding and highlighted key risks going forward, in particular relating to whether methods are in place to demonstrate target engagement and pharmacological effect. The value of this modeling exercise will be discussed in detail and in the context of the clinical phase II data, together with recommendations to enable optimal future evaluation of FAAH inhibitors.

Project description:Chronic pain is one of the most significant and costly medical problems throughout the world. Recent evidence has confirmed the hippocampus as an active modulator of pain chronicity but the underlying mechanisms remain poorly defined. By means of in vivo electrophysiology together with chemogenetic and optogenetic manipulations in freely behaving mice, we identified a neural ensemble in the ventral hippocampal CA1 (vCA1) that showed inhibitory responses to noxious external stimuli, but not to innocuous stimuli. Following peripheral inflammation, this neuronal ensemble became responsive to innocuous stimuli and causally contributed to sensory hypersensitivity in inflammatory animals. Mimicking this inhibition of vCA1 neurons using chemogenetics in naïve mice induced chronic pain-like behavioral changes, whereas activating these vCA1 neurons in mice with chronic peripheral inflammation resulted in a striking reduction of pain-related behaviors. Pathway-specific manipulation of vCA1 projections to the basolateral amygdala (BLA) and infralimbic cortex (IL) showed that these pathways were differentially involved in pain modulation at different temporal stages of chronic inflammatory pain. These results confirm a crucial role of the ventral hippocampus and its circuits in modulating the development of chronic pain in mice.
Project description:While depression and chronic pain are frequently comorbid, underlying neuronal circuits, and their relevance for the understanding of psychopathology, remain poorly defined. Here we show in mice that hyperactivity of the neuronal pathway linking the basolateral amygdala to the anterior cingulate cortex is essential for chronic pain-induced depression. In naive male mice, we demonstrate that activation of this pathway is sufficient to trigger depressive-like behaviors, as well as transcriptomic alterations that recapitulate core molecular features of depression in the human brain. These alterations notably impact gene modules related to myelination and the oligodendrocyte lineage. Among these, we show that Sema4a, a hub gene significantly upregulated in both male mice and humans in the context of altered mood, is necessary for the emergence of depressive-like behaviors. Overall, these results place the BLA-ACC pathway at the core of pain and depression comorbidity, and unravel the role of impaired myelination and Sema4a in mood control.

Project description:Neuroinflammation is a major component in the transition to and perpetuation of neuropathic pain states. Spinal neuroinflammation involves activation of TLR4, localized to enlarged, cholesterol-enriched lipid rafts, designated here as inflammarafts. Conditional deletion of cholesterol transporters ABCA1 and ABCG1 in microglia, leading to inflammaraft formation, induced tactile allodynia in naïve mice. The apoA-I binding protein (AIBP) facilitated cholesterol depletion from inflammarafts and reversed neuropathic pain in a model of chemotherapy-induced peripheral neuropathy (CIPN) in wild-type mice, but AIBP failed to reverse allodynia in mice with ABCA1/ABCG1-deficient microglia, suggesting a cholesterol-dependent mechanism. An AIBP mutant lacking the TLR4-binding domain did not bind microglia nor reversed CIPN allodynia. The long-lasting therapeutic effect of a single AIBP dose in CIPN was associated with anti-inflammatory and cholesterol metabolism reprogramming and reduced accumulation of lipid droplets in microglia. These results suggest a cholesterol-driven mechanism of regulation of neuropathic pain by controlling TLR4 inflammarafts and gene expression program in microglia and blocking the perpetuation of neuroinflammation.
