RESUMEN
Aim: To evaluate the behavior of oral keratinocytes in the presence of Vitamin C (Vit C) and its anti-inflammatory potential. Materials & methods: Oral keratinocytes were initially exposed to 0.1-2.5 mM of Vit C and the metabolic activity and cell migration were evaluated using MTS assay and Ibidi culture inserts, respectively. After, the cells were challenged with Candida albicans and inflammatory markers were analyzed by qPCR. Results: The treatment was not cytotoxic, and the highest concentrations increased the metabolic activity at 24 h. Vit C delayed the cell migration at 48 and 72 h. Interestingly, it downregulated the genes IL-8 and IL-1ß. Conclusion: Vit C could be an interesting adjuvant to anti-fungal treatment due to its anti-inflammatory potential.
Vitamin C, also known as ascorbic acid, is a vitamin commonly found in fruits and vegetables. It is popular for supporting our immune system, so is commonly taken as a supplement. We looked at the action of vitamin C on cells from the mouth and its potential to reduce inflammation in a fungal disease of the mouth oral candidiasis. We showed that vitamin C is not toxic to cells of the mouth and may reduce inflammation in cells infected by the fungus. This suggests that vitamin C could be used as a complementary therapy for oral candidiasis.
