γδ T Cells Contribute to Injury in the Developing Brain.

ABSTRACT: Brain injury in premature infants, especially periventricular leukomalacia, is an important cause of neurologic disabilities. Inflammation contributes to perinatal brain injury development, but the essential mediators that lead to early-life brain injury remain largely unknown. Neonates have reduced capacity for mounting conventional αβT-cell responses. However, γδT cells are already functionally competent during early development and are important in early-life immunity. We investigated the potential contribution of γδT cells to preterm brain injury using postmortem brains from human preterm infants with periventricular leukomalacia and two animal models of preterm brain injury-the hypoxic-ischemic mouse model and a fetal sheep asphyxia model. Large numbers of γδT cells were observed in t
