Premature thymic involution in young Foxn1lacz mutant mice causes peripheral T cell phenotypes similar to aging-induced immunosenescence.

Abstract excerpt

The thymus is a primary lymphoid organ generating self-restricted and self-tolerant naïve T cells. Early in life the thymus starts to involute, resulting in decreased naïve T cell output which may be more self-reactive, leading to an increased prevalence of autoimmunity. A decrease in the transcription factor FOXN1 is an early event in thymic involution. Using the Foxn1lacz model, we studied how premature thymic...
