Although inflammatory mechanisms have been linked to neuronal injury following
global cerebral ischemia, the presence of infiltrating peripheral immune cells
remains understudied. We performed flow cytometry of single cell suspensions
obtained from the brains of mice at varying time points after global cerebral
ischemia induced by cardiac arrest and cardiopulmonary resuscitation (CA/CPR) to
characterize the influx of lymphocytes into the injured brain. We observed that
CA/CPR caused a large influx of lymphocytes within 3h of resuscitation that was
maintained for the 3day duration of our experiments. Using cell staining flow
cytometry we observed that the large majority of infiltrating lymphocytes were
CD4(+) T cells. Intracellular stains revealed a large proportion of
pro-inflammatory T cells expressing either TNF? or INF?. Importantly, the lack of
functional T cells in TCR? knockout mice reduced neuronal injury following
CA/CPR, implicating pro-inflammatory T cells in the progression of ischemic
neuronal injury. Finally, we made the remarkable observation that the novel
CD4(+)CD40(+) (Th40) population of pro-inflammatory T cells that are strongly
associated with autoimmunity are present in large numbers in the injured brain.
These data indicate that studies investigating the neuro-immune response after
global cerebral ischemia should consider the role of infiltrating T cells in
orchestrating the acute and sustained immune response.
