In the present study, inflammation, reflected as induction of Il1b, Il6, and Tnf, after exposure to chemotherapy was evident, but we found no phenotypic differences in inflammatory parameters when evaluating Pglyrp2. It is therefore likely that Pglyrp2 plays a secondary role in the development of chemotherapy-induced gastrointestinal mucositis. The gene discussed is IL1B; the disease is gastrointestinal mucositis.
