Abstract—
Using the immunofluorescence confocal microscopy, we detected the following GABAergic structures in the somatic muscle of the body wall of the earthworm: neurotransmitter gamma-aminobutyric acid (GABA); the enzyme responsible for synthesis of GABA, glutamate decarboxylase; type 1, 2, and 3 membrane transporters of GABA providing its reuptake; pre- and postsynaptic type A (ionotropic) and type B (metabotropic) GABA receptors. These structures are localized in the areas of cholinergic neuromuscular synapses. We assume that GABA can participate in modulation of motor activity of the earthworm somatic muscles both at pre- and postsynaptic levels of cholinergic neuromuscular synapses.
期刊介绍：
Biochemistry (Moscow), Supplement Series A: Membrane and Cell Biology is an international peer reviewed journal that publishes original articles on physical, chemical, and molecular mechanisms that underlie basic properties of biological membranes and mediate membrane-related cellular functions. The primary topics of the journal are membrane structure, mechanisms of membrane transport, bioenergetics and photobiology, intracellular signaling as well as membrane aspects of cell biology, immunology, and medicine. The journal is multidisciplinary and gives preference to those articles that employ a variety of experimental approaches, basically in biophysics but also in biochemistry, cytology, and molecular biology. The journal publishes articles that strive for unveiling membrane and cellular functions through innovative theoretical models and computer simulations.
