        Instead of being regarded as just an immature version of the adult immune system, the immune system in early life increasingly is being recognized as different, with a bias toward the induction of a Th2 response or of immune tolerance. Originally proposed as a hypothesis by Adrian Hayday, there is increasing evidence, including our own results, that γδ T cells are important in early life. Although in humans circulating T cells can be detected as early as 12.5 wk gestation, most information on T cells in early life, including γδ T cells, is derived from studies on cord blood at term delivery (>37 wk gestation). We found that fetal blood around midgestation (before 30 wk) contained high levels of Vγ9Vδ2 T cells. These lymphocytes expressed a semi-invariant TCR, were phosphoantigen reactive, and showed a preprogrammed effector potential, suggesting that these γδ T cells may fulfill an important role in the immunosurveillance of fetal tissues.
