- the inventors used a murine model which makes it possible to measure postoperative pain and which is known to be a good model of pain associated with surgical acts (Pogatzki et al. (2003) Anesthesiology 99: 1023-7; Cowie et al. (Pogatzki et al. (2003) Anesthesiology 99: 1023-7; Cowie et al. ( 2019) Bio Profoc. 9: e3140).
- This model is interesting for exploring immediate postoperative pain but also chronic pain such as the latter has often been associated with insufficient treatment of the former (Pogafzki-Zahn et al. (2017) Pain Rep. 2: e588).
- mice under inhaled anesthetic had an approximately 5 mm skin and muscle incision at the sole of the foot of the hind paw (the incision through ⁇ in front of the heel towards the toes) .
- the incision is made in two stages, first the skin and then the flexor flexor muscle of the fingers (or f / exor digiforum brevis) after lifting the latter with a curved forceps.
- the wound is then sutured (nylon 5.0 thread) at two points on the skin. The sutures are removed on the fourth day.
- the pain sensitivity tests carried out in mice by the inventors are tests of mechanical thrust at the plantar level just at the level of the heel, 3 mm from the end of the incision.
- Each filament is applied 5 times for approximately 1 s, with an interval of 10 s between each application, starting with the smallest force, then gradually.
- a withdrawal of the paw following a pressure is considered as a signal, e ⁇ when there were at least 3 withdrawals out of the 5 tests with the same filament, it is considered that there is sensitivity to the force considered.
- the first filament inducing at least 3 withdrawals out of the 5 tests therefore corresponds to the threshold of mechanical sensitivity of a mouse. If no filament induces shrinkage, it is considered that the sensitivity threshold is 4 g force (39.2 mN), which corresponds to the filament of size greater than that of force 2 g. Sensitivity is measured daily for 7 days from the day after the incision.
- mice treated per year ⁇ i-IL-6, untreated to an ⁇ i-IL-6, incised or not incised were compared.
- Two types of treatment were evaluated in this model of postoperative pain: administration of an anti-IL-6 antibody (example 1) and active immunization against an immunogenic peptide derived from murine IL-6 (example 2).
- Example 1 Passive immunization.
- mice which will be incised receiving PBS (6 mice, group 1) or anti-IL-6 antibody (6 mice, group 2) by intraperitoneal injection (ip) one day before the incision;
- mice (group 3) receiving PBS by ip injection and which will follow the operating protocol but which will not be incised (anesthesia and awakening, without incision).
- PBS is injected ip at a rate of 0.3 mL.
- 0.5 mg of the anti-IL-6 polyclonal antibody (R&D Systems, ref AF406 NA) is dissolved in 1 mL of PBS and 0.3 mL of the mixture is injected ip.
- mice immunized against the carrier protein KLH (6 mice, group 3) immunized on D0, D 15, D45, and D75 which will follow the operating protocol on D80 without being cut (anesthesia and awakening without incision).
- the immunizations are carried out by subcutaneous injection in the upper back of the mouse of 100 m ⁇ of ISA51 mixed with 100 ⁇ L of KLH protein (quantity 80 ⁇ g) for groups 1 and 3, and mixed with 100 m ⁇ of KLH ( quantity 80 mg) covalently coupled to the murine IL-6_200 peptide (quantity 40 mr) for group 2.
- the murine IL-6_200 peptide coupled to KLH has the sequence: CMNNDDALAENNLKLPECY (SEQ ID NO: 2) (cyclized by CC bridge ) and has already been described in the publication by Desallais et al. (2014) Arfhrifis Research & Therapy 16: R157.
