Research and Practice Interests

Crutcher Lab Research Program: The research program is focused on two major areas. The first is the study of themechanisms underlying axonal sprouting and abortive regeneration in the mature mammalian brain. The primary model involves studies of axonal sprouting in the CNS or on sections of the CNS. Some of the findings that have emerged from this research programinclude: the demonstration of nerve growth factor (NGF) in the mammalian CNS, increased NGF in the hippocampus following septal denervation, induction of perivascular sympathetic sprouting in response to intraventricular infusion of NGF, CNS white matter inhibition of neurite outgrowth in culture, penetration of the hippocampal neuropil by sympathetic fibers, age-related decreases in target receptivity to sprouting, geometric constraints on axonal regeneration, and the hypothesis of trophomorphism. Current research, funded through the NIH, is focused on identifying the role that NGF plays in regulation of axonal growth in CNS white matter. The second research area involves studies of the role of apolipoprotein E in Alzheimer's disease. This program is funded through a grant from the NIH and focuses on the hypothesis that apoE exhibits isoform-specific neurotoxic effects that may be mediated through proteolytic fragments. Current work involves studies of human brain tissue and transgenic apoE mice.
