PEST Domain-Enriched Tyrosine Phosphatase (PEP) Regulation of Effector/Memory T Cells
Abstract
Protein tyrosine kinases and phosphatases cooperate to regulate normal immune cell function. We examined the role of PEST domain–enriched tyrosine phosphatase (PEP) in regulating T cell antigen–receptor function during thymocyte development and peripheral T cell differentiation. Although normal naïve T cell functions were retained in pep -deficient mice, effector/memory T cells demonstrated enhanced activation of Lck. In turn, this resulted in increased expansion and function of the effector/memory T cell pool, which was also associated with spontaneous development of germinal centers and elevated serum antibody levels. These results revealed a central role for PEP in negatively regulating specific aspects of T cell development and function.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
