Resumo

Inflammatory bowel diseases are debilitating illnesses characterized by severe inflammation of the gastrointestinal tract. Treatments currently available are expensive and ineffective. We here investigated the role of red-light emitting diode (LED) on dextran sodium sulfate (DSS)-induced colitis. DSS was added to the drinking water of male mice at days 0, 2, 4 and withdrawn at day 6. LED irradiation was performed daily for 90s from day 6 to 9 on the right and left sides of the ventral surface and beside the external anal region. LED treatment decreased the amount of crypt dysplasia/edema, inflammatory infiltrates and ulcers, attenuated apoptosis and increased proliferation of crypt cells. Also, LED treatment induced expression of annexin Al in the damaged epithelium, preserved the organization of claudin-1 and skewed cytokine profiling towards a more anti-inflammatory status. Thus, LED treatment promotes structural protection and modulates the inflammatory response, constituting a potential non-invasive and low-cost combined therapy to help patients achieve disease remission.
