NPY and CGRP Inhibitor Influence on ERK Pathway and Macrophage Aggregation during Fracture Healing

Aim: The aims of this study are to investigate the effects of neurotransmitters NPY and CGRP on ERK signaling in fracture healing, and to identify the correlation between macrophage aggregation and fracture healing. Methods: Male Sprague-Dawley rats were used to build a fracture model. The neurotransmitter receptor inhibitors were injected intraperitoneally into the rats. Immunofluorescence staining and ELISA were employed to determine the...
