Is there a flame in the brain in psychosis?

摘要

For many decades, it was believed that the brain was immunologically privileged, hence it was surprising when Shatz and colleagues (1) reported in 2000 that a number of immune proteins (cytokines and major histocompatibility complex [MHC] proteins) were not just present in the brain but were localized at functional synapses. Subsequent work has shown that these molecules play a major role in brain development as well as in mature synaptic function and plasticity (2,3).
