Interferon α2b Selectively Modulates Ionotropic AMPA, but not NMDA Receptors of the Glutamatergic Synapse of the Vestibular Apparatus.
Interferon (IFN) used in the treatment of severe viral infections and cancer can lead to acute hearing loss and balance problems. The effect of type I interferon IFNα2b on the function of the afferent glutamatergic synapse of the vestibular epithelium was studied in vitro using electrophysiological method and perfusion of the synaptic area with solutions containing glutamate (GLU) and ionotropic glutamate receptor agonists (AMPA, NMDA). IFNα2b selectively activates AMPA, but not NMDA receptors, and modulates the afferent flow from the sensory epithelium to CNS. The delayed activation of AMPA receptors is one of the mechanisms of the neuromodulatory effect of IFNα2b on glutamatergic synaptic transmission in the vestibular apparatus.
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.
