Epineural optogenetic activation of nociceptors initiates and amplifies inflammation

Stéphanie Lacour, Katia Galan, Ivan Furfaro, Outman Akouissi, Frédéric Pierre Gérald Michoud

Activation of nociceptor sensory neurons by noxious stimuli both triggers pain and increases capillary permeability and blood flow to produce neurogenic inflammation(1,2), but whether nociceptors also interact with the immune system remains poorly understo ...
