To investigate the in vivo role of glial cells in synaptic function, maintenance, and development, we have developed an approach to selectively ablate perisynaptic Schwann cells (PSCs), the glial cells at the neuromuscular junction (NMJ), en masse from live frog muscles. In adults, following acute PSC ablation, synaptic structure and function were not(More)
To explore novel roles of glial cells in synaptic function and formation, we examined the expression of agrin in frog Schwann cells and tested their role in the aggregation of acetylcholine receptors (AChRs). Using reverse transcription-PCR, we found that Schwann cells along nerve fibers in tadpoles expressed only the inactive agrin isoform B0 but began to(More)
We have developed a specific and sensitive method to detect the human pathogen Aspergillus fumigatus by polymerase chain reaction (PCR) with an objective of detecting the organism in peripheral blood and urine which can be obtained by non-invasive procedures. A pair of oligonucleotide primers for PCR were designed based on the published partial protein(More)
BACKGROUND Aspergillus fumigatus, a common environmental fungus, is responsible for a number of lung disorders, including allergy and infection, in human beings. For immunodiagnosis of these diseases, standardized, pure, and relevant antigens are not currently available. METHODS A complementary DNA library of A. fumigatus was constructed with messenger(More)
Like other vertebrate synapses, the neuromuscular junction (NMJ) has glial cells that are closely associated with the pre- and post-synaptic components. These "perisynaptic Schwann cells" (PSCs) cover nerve terminals and are in close proximity to the synapse, yet their role at the NMJ has remained mysterious for decades. In this review we explore historical(More)
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease leading to cell death of predominantly motor neurons. Despite extensive research in this disease, finding a way to slow the progress of the disease has been challenging. RNA-targeted therapeutic approaches, including small interfering RNA and antisense oligonucleotides are being developed(More)
The changes in the pattern of production and detoxification of ammonia have been studied in the skeletal muscles and blood of rats of different age groups (1, 3, 6, 12 and 24 months), subjected to exhaustive exercise. The protein profiles at exhaustion showed a sharp drop in all muscles and the decrement was more in the senile rats. In general, the muscle(More)
Secretions of salivary glands are essential for the maintenance of oral health. Due to the lack of suitable in vitro models, studies to examine biochemical and molecular mechanisms of the cellular secretions have been difficult. Furthermore, adequate quantities of human epithelial cells could not be obtained, because normal diploid cells are believed to(More)
