Mast cell stabilization promotes antinociceptive effects in a mouse model of postoperative pain

The mast cell appears to be more important than many scientists thought. Rita Levi-Montalcini already pointed out that mast cells are not Cinderella cells of immunology, but real diva’s!

Abstract

Background

Nerve injury and consequent inflammatory responses produced by surgical incision result in a complicated pain status which still affects half of all surgical patients. Therefore, it is essential for anesthesiologists to identify the mechanisms of postoperative pain. Mast cells are resident cells of connective tissue and the mucosa that participate in the immune response. Degranulation of mast cells is involved in the development of postoperative pain and can be induced by surgical incision. The aim of this study was to investigate whether stabilization of mast cells causes an antinociceptive effect in a mouse model of postoperative pain.

Methods

Postoperative pain was induced by making an incision in the hind paw of BALB/c mice. The mast cell membrane stabilizer cromoglycate (200 μg/20 μL) was…
