Previously, we observed that an adenoviral (Ad) vector encoding human glial cell line-derived neurotrophic factor (GDNF), injected near the rat substantia nigra (SN), protects SN dopaminergic (DA) neuronal soma from 6-hydroxydopamine (6-OHDA)-induced degeneration. In the present study, the effects of Ad GDNF injected into the striatum, the site of DA nerve(More)
Glial cell line-derived neurotrophic factor (GDNF) supports growth and survival of dopaminergic (DA) neurons. A replication-defective adenoviral (Ad) vector encoding human GDNF injected near the rat substantia nigra was found to protect DA neurons from the progressive degeneration induced by the neurotoxin 6-hydroxydopamine (6-OHDA) injected into the(More)
BACKGROUND The long-term use of methamphetamine (MAMP) can result in psychosis but it is not clear why some individuals develop psychotic symptoms, while others use MAMP regularly over long periods and remain unscathed. We set out to characterize MAMP users and to examine the relationship of pre-morbid personality, pre-morbid social function and other(More)
Langerhans cells act as antigen-presenting cells in immune reactions in the skin. What other roles they may play in inflammation is less well defined. We have tested whether these cells can produce TNF-alpha, an important mediator of inflammation. Resting Langerhans cells produce less than 0.1 U TNF-alpha/ml. Langerhans cells stimulated with phorbol(More)
Proteoglycan aggregates, the binding of disc proteoglycan to hyaluronate, chondroitin sulfate chain length, hexosamine and amino acid compositions were measured in different regions of the L1/L2 and L4/L5 intervertebral discs from 3 spines aged 35, 49, and 60 years. The results were as follows: proteoglycan aggregates and the binding of disc proteoglycan to(More)
