Cui, Guang-Lin. "Functional Aspects of the ECL Cell in Rodents". Doctoral thesis, Norwegian University of Science and Technology, Faculty of Medicine, 2001. http://urn.kb.se/resolve?urn=urn:nbn:no:ntnu:diva-999.
Pełny tekst źródłaGastric acid plays an important role in digesting food (especially proteins), iron absorption, and destroying swallowed micro-organism. N4 is secreted by the oxyntic parietal cells. Its secretion is regulated by endocrine, neurocrine and paracrine mechanisms. Gastrin released from the antral G cell is the principal physiological stimulus of gastric acid secretion. The ECL cell is accepted as the source of histamine participating in the regulation o f acid secretion and is functionally and trophically controlled by gastrin. Amidated gastrin is the main biologically active form of gastrin, and its main precursor Gly-G-17 was formerly thought to be without any biological activity. However, recent studies raised the possibility of both secretory and trophic effects of Gly-gastrin. No Glt-G-17 receptor has been cloned yet. In paper I, the effect of this peptide on gastric acid secretion was examined in the totally isolated vascularly perfused rat stomach. This study clearly demonstrates that the administration of Gly-G-17 in high doses was followed by an increase in histamine release and gastric acid output. Moreover, Gly-G-17 induced gastric acid secretion was completely inhibited by the H2 receptor antagonist ranitidine. Thus, the natural interpretation of these data is that Gly-G-17 is a weak gastrin agonist, interacting with the CCK-2 receptor on the ECL cell, resulting in a subsequent release of histamine, which in turn stimulates the parietal cell. The stomach is also regulated by nerves, principally by the vagal nerves. The gastric neurons contain various neuropeptides, some of them, such ad PACAP are known to influence gastric acid secretion. In paper II, PACAP was studied with respect to the effect on gastric acid secretion using totally isolated vascularly perfused rat stomachs, chronic fistula rats and isolated parietal cells. The results show that its stimulatory effects on gastric acid secretion is mainly due to an increase in histamine release from the ECL cell. PACAP is a powerful stimulator of histamine release from the ECL cell.
As mentioned above, aside from its stimulatory effect on gastric acid secretion, gastrin also has a trophic effect on the oxyntic mucosa, especially on the ECL cell. A definite connection has been found between hypergastrinemia and gastric carcinoids both in rats and humans. Moreover, some of the gastric adenocarcinomas in rodents with hypergastrinemia have been reclassified as ECLomas. However, spontaneous gastric ECL omas in laboratory animals are extremely rare. Japanese cotton rats (Sigmodon hispidus) have a very high incidence of gastric carcinomas occurring predominately in females, and which we previously showed, were associated with achlorhydria and hypergastrinemia. In paper III, the gastric carcinomas in cotton rats are described further. Particularly the oxyntic mucosa outside the tumour is shown to contain normal parietal cells indicating a normal ability to produce acid.
Long-term potent inhibitors of acid secretion resulting in secondary hypergastrinemia will induce ECL cell hyperplasia and probably carcinoids. Accordingly, the induction of ECL-cell hyperplasia and carcinoids remains a topic of considerable concern, especially in young individuals. Furthermore, the stomach is important for the absorption of calcium. Achlorhydria has been described as causing impairment of calcium absorption. Thus, a mechanism related to gastric acid secretion has been postulated to be involved in osteopenia developing in patients after gastric resection. More specifically, a postulated peptide, gastrocalcin, has been hypothesised to exist in the ECL cell. We therefore examined the effect of long-term hypergastrinemia secondary to drug induced hypoacidity with respect to bone developing in young male rats (paper IV). Long-term potent acid inhibition evoked a marked increase in plasma gastrin levels, leading to enlargement of oxyntic mucosa with ECL cell hyperplasia. However, body weight and bone mineral density were reduced in the hypergastrinemic young male rats. These findings do not support the hypothesis that the ECL cell plays a role in bone metabolism.
Finally, anaesthetized animal models have been widely used to study gastric acid secretion. However, anaesthetic agents also affect acid output. Anaesthetic agents naturally reduce acid secretion by interaction with neural activity, but could also play a role by affecting the function of the different cells taking part in the regulatory chain of acid secretion as well as the parietal cell itself. In paper V, the totally isolated vascularly perfused rat stomach was used to study the effect of anaesthetic agents on the ECL cell and the parietal cell functions. The results indicate that anaesthetic agents can also affect gastric acid secretion through a direct inhibitory action on parietal cells and ECL cells.

Pełny tekst źródłaNeuronal networks spontaneously generate “immature” patterns of activity during development, which are thought to participate on the formation of neural circuits. Local neocortical as well as hippocampal circuits generate synchronised neuronal discharges providing support for Hebbian plasticity. Studies of sensory systems showed that local pauci-neuronal circuits were able to generate synchronous activity while isolated from other brain structures. Isolated spinal cord produces bursts evoking muscle twitching, light insensitive retina generates waves of activity, as well as other brain regions generate synchronous activities before fulfilling the function for which they are intended. Similarly, the hippocampus of newborn rat or premature primate in vitro, as well as immature neocortex in vitro, generates synchronised neuronal activity called giant depolarising potentials (GDPs). Based solely on these studies and taking into account the delayed maturation of certain long-distance neuronal projections, it would be tempting to conclude that the immature brain functions as a set of small functional modules that self-maintain their intrinsic activity before connecting together to create a functional adult brain. However, some long-distance connections are formed very early during development and allow the propagation of oscillations between immature connected structures. Indeed, retinal waves propagate to the lateral geniculate nucleus and then to the visual cortex, hippocampal GDPs propagate to the contralateral hippocampus, septum and entorhinal cortex, and finally, twitching, creating a sensory feedback, triggers immature gamma oscillations and spindle bursts in the thalamo-cortical network. A similar functioning is described in the premature newborn. It therefore seems more likely that the brain is, during the early stages of development, organised into functional subsystems interconnected anatomically and functionally. Within functional units are generated immature patterns of synchronous activity to create topographically organised connections that serve as anatomical basis of the final function. If these developmental stages are disturbed during critical periods, the system cannot perform its function adequately in mature stage. The mature hippocampus, or more precisely the cortico-hippocampal circuits, plays a key role in declarative memory, spatial organisation and behavioural inhibition. The establishment of these functions is progressive during development. For example, human adults rarely have personal memories dating before the age of three years. However, we now know that the human baby is able to keep memories in declarative memory (hippocampus-dependent) during the first year of life with increasing efficiency, but will not remember them in the adulthood. We do not know if the encoding of the memories is different or a secondary process inhibits the access to the early memories. We can assume that changes in electrophysiological activity during development support modification of these functions. In this thesis, we wanted to know how and from when the hippocampus, which receives convergent information from many cortical areas, acquires his adult mode of functioning. To answer this question we studied the entorhinal cortex-hippocampus system, entorhinal cortex being the main excitatory input to the hippocampus and receiving afferents from many parts of the neocortex. We were able to distinguish several periods in the development of the immature hippocampus: Period from P1 till P12 characterised by the sole presence of immature sharp waves triggered by the entorhinal cortex. Period from P13, when two types of sharp waves coexisted: the immature sharp waves and sharp waves as described in the adult animals newly emerged. The mature sharp waves, unlike the immature, can be accompanied by ripples. (...)
