| Outline of Final Research Achievements |
We attempted detection of human IL-10 produced regulated B cells from airway local (induced sputum) and systemic (peripheral blood) using flow cytometry. The frequency of B cell (CD 19 positive) differentiations of the total lymphocytes in induced sputum and peripheral blood in healthy individuals were about 1.0% and 10%, respectively, and there was no significant difference in frequency of B cell differentiations between healthy individuals and asthmatic patients. Furthermore, the IL-10 produced regulatory B cell differentiations peripheral blood were about 0.6% of B lymphocytes, and there was no difference in frequency of regulatory B cell differentiations between healthy individuals and asthmatic patients.
