Laboratory for Neurotoxicity Studies
The Virginia Tech Laboratory for Neurotoxicity Studies, located at the Virginia-Maryland Regional College of
Veterinary Medicine, conducts investigations studying the effects of toxins on the nervous system.
Current programs of the Laboratory include:
- Research - Interdisciplinary investigations in experimental neurotoxicology studying the effects
of agents, such as pesticides, solvents, heavy metals, mycotoxins and nanomaterials, in in vitro and
in vivo models, funded by federal agencies and industry. Faculty with expertise in toxicology,
pharmacology, neuropathology and veterinary pathology conduct this work.
- Education - Graduate programs in relevant disciplines are available at the masters and doctoral
levels, including neuroanatomy, neurotoxicology, neurology, and neuropathology. Trainees gain experience
with the quality standards of the Good Laboratory Practice (GLP) regulations to increase opportunities in laboratories
of government and industry.
- Good Laboratory Practice Compliant Services- General and neuropathology services of the laboratory
are compliant with the federal GLP regulations and available to industry to support product
development and safety assessment. This includes transmission electron microscopy,
immunohistochemistry and morphometry. The laboratory has over 20 years of experience in supporting
GLP-compliant studies.
Expertise
- Staffed by highly-skilled, experienced laboratory technicians working closely with faculty members
in active research programs
- Expertise in histology, electron microscopy, biochemistry, neurobehavior, toxicology, tissue culture,
and immunohistochemistry
- Additional support services for research investigations provided by Morphology Service Laboratory and
Veterinary Teaching Hospital Histopathology Laboratory
