Outline of Final Research Achievements	Microarray analysis suggested that PTEN is involved in the signal transduction of regulatory B cell development. Conditional kick-out mice that has no PTEB expression specifically in B cells were generated. In this mouse, a novel regulatory B cell subset was identified in B-1 cell population. This subset has potent suppressing capability in various immune responses, and thus is considered as a potential target in treating autoimmune diseases and cancers. Additionally, new cell surface markers for regulatory B cells are identified.
