Research Interest:

Pathophysiology and pharmacology of neuropathic pain. By combining molecular, cell biology, biochemical (microdialysis) and behavioral approaches, our team is deciphering the role of 5-HT2A and 5-HT6 serotonin receptors and/or their signalling pathways in order to propose alternative strategies for the treatment of neuropathic pain and associated comorbidities.

Key words: Neuropathic pain, serotonin, antidepressants, 5-HT2A receptor, 5-HT6 receptor

Technical expertise:

- Spinal microdialysis in awake rats;

- Animal behavioural tests (nociception, anxiety, cognition, depression);

- Experimental models of neuropathic pain (STZ-, SNL-, CC-I, Oxaliplatin-induced neuropathic pain in rats)
