- Abstract
- The induction of the p75 neurotrophin receptor (p75NTR) on striatal cholinergic neurons by global hypoxic-ischemia has been reported to promote neuron survival. We have found, however, while the p75NTR-expressing neurons survive the insult for the first 5 days, subsequently they undergo shrinkage, loss of choline acetyl transferase (ChAT) expression, and more than 96% are eventually lost by 8 days. In contrast ChAT-expressing cells in the surrounding region of the infarction, do not express p75NTR and there is no evidence of neuronal loss. These results suggest the expression of p75NTR on cholinergic interneurons of the rat striatum is associated with delayed neuronal degeneration. (C) 2002 Elsevier Science Ireland Ltd.
