Pinto LG, Souza GR, Kusuda R, Lopes AH, Sant’Anna MB, Cunha FQ, Ferreira SH, Cunha TM (2019) Non-peptidergic nociceptive neurons are essential for mechanical inflammatory hypersensitivity in mice. Mol Neurobiol 56(8):5715-5728. doi: 10.1007/s12035-019-1494-5
Objective: To determine the role of non-peptidergic nociceptors in mediating mechanical inflammatory hypersensitivity in mice.
Summary: rIB4-SAP oblates non-peptidergic neurons as displayed by the decrease of purinoceptor 3. The depletion of these neurons inhibited the mechanical inflammatory sensitivity induced by GDMF and carrageenan, but not by other expected factors such as nerve growth factor implying the role of this subset of neurons to be one of mediation as opposed to direct nociception.
Usage: IB4-SAP (0.16–3.2 μg/5 μl, i.t.), unconjugated Saporin (as control, 1.8 μg/5 μl, i.t.), or saline (vehicle, 5 μl/i.t.) were injected into the subarachnoid space on the midline between the L5 and L6 vertebrae.
