The Bottini laboratory is currently focused on the tyrosine phosphatase LYP, encoded by PTPN22, a major T1D gene. LYP is a critical negative regulator of T lymphocyte activation. During his postdoctoral training, Dr. Bottini discovered that a mutation in the PTPN22 gene is a predisposing factor for T1D. Research is ongoing to understand the mechanism of action of LYP in T1D and its molecular regulation.
The Bottini laboratory is a proud supporter of the JDRF effort to find a cure for T1D. T1D-relevant research in the Bottini laboratory has been repeatedly funded by the JDRF in the recent past, and Dr. Bottini is currently a Member of the JDRF Autoimmunity Study Session.
