Abstract
In experiments on the motor nerve endings of the diaphragm of transgenic FUS mice with a model of amyotrophic lateral sclerosis at the pre-symptomatic stage of the disease, the processes of transmitter release and endocytosis of synaptic vesicles were studied. In FUS mice, the intensity of transmitter release during high-frequency stimulation of the motor nerve (50 imp/sec) was lowered. At the same duration of stimulation, the loading of fluorescent dye FM1-43 was lower in FUS mice. However, at the time of stimulation, during which an equal number of quanta are released in wild-type and FUS mice, no differences in the intensity of dye loading were found. Thus, endocytosis is not the key factor in the mechanism of synaptic dysfunction in FUS mice at the pre-symptomatic stage.
期刊介绍：
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
