Protective Effect of Latex Proteins on Intestinal Mucositis Induced by 5-Fluorouracil.

Intestinal mucositis is characterized by inflammation and ulceration of the mucosa that affects the gastrointestinal tract and is associated with administering some drugs, such as 5- Fluorouracil (5-FU), conventional chemotherapy used in clinics for cancer therapy. Inside intestinal mucosa, the 5-FU acts, leading to oxidative stress, stimulating the production/release of proinflammatory cytokines, local accumulation of neutrophils and consequent tissue damage. These alterations favor bacterial proliferation, triggering secondary infections, and are responsible for undesired effects such as myelosuppression and diarrhea.
