Blood resident lymphocytes can break through the BBB during a Multiple
Sclerosis relapse, where they are directed to inflammation sites by IL-10.
I don't think this normally ever happens though. As far as I know,
macrophages can do the same thing. I'd imagine that any oxygen required by
the neuron is provided via the  astrocyte, as there are no RBCs in CSF.
