Focus on the spatial organization of signalling.
Since the early days of light microscopy it has been apparent that cells are highly organized and compartmentalized. However, only in recent decades has the molecular basis of this spatial organization and its functional role in cellular signalling events emerged. Furthermore, modern molecular and imaging techniques, together with the intricate combination of cellular and developmental biologic...
متن کاملEffect of gonadotrophin-releasing hormone aned human chorionic gonadotrophin on the response of the ewe to pregnant mare serum gonadotrophin.
An experiment was conducted to determine whether gonadotrophin-releasing hormone (Gn-RH) or HCG would reduce the proportion of unruptured follicles in the Galway ewe following a high superovulating dose of PMSG given in conjunction with a progestagen to synchronize oestrus. Forty-four Galway ewes aged 1\m=1/2\to 5 years (average wt 64\m=.\7kg) were treated with intravaginal pessaries impregnate...
متن کاملEffects of changing gonadotrophin-releasing hormone pulse frequency on gonadotrophin secretion in men.
To investigate the effects of alterations in GnRH pulse frequency on gonadotrophin secretion, we administered low dose GnRH pulses (25 ng/kg) at hourly or 2-hourly frequencies to eight normal men. All subjects received GnRH pulses i.v. every 2 h for 88 h. Following this, exogenous GnRH was discontinued in four normal men (Group A, GnRH withdrawal), and the frequency of GnRH injections was incre...
متن کاملOptogenetic Modulation of Intracellular Signalling and Transcription: Focus on Neuronal Plasticity
Several fields in neuroscience have been revolutionized by the advent of optogenetics, a technique that offers the possibility to modulate neuronal physiology in response to light stimulation. This innovative and far-reaching tool provided unprecedented spatial and temporal resolution to explore the activity of neural circuits underlying cognition and behaviour. With an exponential growth in th...
متن کاملFocus on Extracellular Vesicles: Physiological Role and Signalling Properties of Extracellular Membrane Vesicles
Extracellular vesicles (EVs) are a heterogeneous population of secreted membrane vesicles, with distinct biogenesis routes, biophysical properties and different functions both in physiological conditions and in disease. The release of EVs is a widespread biological process, which is conserved across species. In recent years, numerous studies have demonstrated that several bioactive molecules ar...
