Core Tip
Core Tip: A model of chronic cross-organ visceral sensitization in mice was developed using ultrasound-guided intravesical injections of acetic acid. Visceral hypersensitivity to colorectal distension was observed as early as 1 h post-injection and lasted up to 7 d. Visceral hypersensitivity was associated with an increased expression of c-Fos protein in the spinal cord. The NK1 receptor and MAPK-p38 levels were upregulated in the spinal cord 7 d post-injection. Colorectal sensitization was prevented by intrathecal or intracerebroventricular injections of minocycline, a microglia inhibitor, by intracerebroventricular injection of CP-99994, a NK1 antagonist, and by intracerebroventricular injection of SB203580, a MAPK-p38 inhibitor.
