Developmental immunohistochemistry of the 22 kDa peroxisomal membrane protein in the human brain.
We studied immunohistochemically the 22 kDa peroxisomal membrane protein (PMP 22). In the control brain, the immunopositive neurons for PMP 22 appeared 2-3 weeks earlier than those for peroxisomal enzymes. PMP 22-immunopositive glial cells appeared at 26-27 gestational weeks, increased with gestational age, and were rarely recognized after 1 year of age. In the patients with Zellweger syndrome, PMP 22-immunoreactivity was recognized in neurons, glias, liver and kidney cells.
