The aim of the study was to investigate the immunomodulating effect of β-1,3/1,6 glucan from yeast on the production of interleukin-4 (IL-4), interleukin-5 (IL-5) in a medium of peripheral venous blood leukocytes from patients with periodontitis.
The study was performed using venous blood of 22 patients, aged 20 to 45 years, suffering from untreated severe chronic generalized periodontitis confirmed by clinical and radiological examination, and 22 periodontally healthy subjects. The effects of β-1,3/1,6 glucan on the production of the cytokines IL-4 (pg/ml) and IL-5 (pg/ml) levels by unstimulated and stimulated leukocyte incubation medium with unopsonized E. coli were determined using the Enzymes Linked Immunosorbent Assay (ELISA) method.
We found that the incubation medium of stimulated leukocytes by unopsonized E. coli and treated with 0.2 mg and 0.4 mg of ß -1,3/1,6-glucan of patients with periodontitis produced significantly higher (P<0,001; P<0,001) levels of IL-4 and IL-5 than the analogous medium of healthy subjects.
This study indicates that β-1,3/1,6-glucan may significantly increase production of IL-4 and IL-5 cytokine levels in a stimulated peripheral blood leukocytes incubation medium from periodontitis patients.
