Incidence and Properties of Thermosensitive TRP Ion Channels in Cellular Models of Sensory Neurones
Loudová, Leona ; Vlachová, Viktorie (advisor) ; Boušová, Kristýna (referee)
Primary afferent sensory neurons enable all living organisms to survive in their environment and react to dangerous stimuli, including noxious and irritant chemicals, temperature, and pressure. These pseudo-unipolar neurons represent a heterologous population that, depending on functional properties, morphology, receptor equipment, degree of myelination, and conduction velocity, determines the intensity at which a stimulus is converted to an electrical signal that is then conducted to the central nervous system to elicit defensive response. The cell bodies of the peripheral sensory neurons are localized in the dorsal root ganglia (DRG) and cell lines derived from these neurons are intensively used not only to study the mechanisms of pain, but also to rationally search for substances with potential analgesic effect. The main goal of this bachelor's thesis is to summarize the current research on molecular mechanisms of nociception using cell lines derived from DRG neurons with a focus on a specific group of temperature-sensitive transient receptor potential (thermoTRP) ion channels. The aim is to present currently available studies focusing on cellular and molecular differences that result from different methodological approaches to the preparation and cultivation of cell cultures, especially in the...
