The human carotid body is a small structure located at the upper end of the common carotid artery. It consists of nerve fibers, connective tissue, and clusters of parenchyma which contain two kinds of cells—chief and sustentacular (Schwann) cells. In addition to these two kinds of cells, there are enlarged nerve terminals in the parenchyma’ so that the

Dendritic cells: the commanders-in-chief of mucosal immune defenses
Current Opinion in Gastroenterology, 2006Intestinal dendritic cells have emerged as key regulators of immunity to pathogens, oral tolerance and intestinal inflammation. Studies have begun to elucidate the regulatory mechanisms responsible for defining region- and compartment-specific phenotypes and functions of dendritic cells in mucosal tissues.Specific subsets of dendritic cells appear to ...

Hormonal effects on development of the secretory apparatus of chief cells
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1987We used light microscopy, transmission electron microscopy, and stereological point-counting methods to investigate the response of rat gastric chief cells to corticosterone and thyroxine during postnatal development. Administration of corticosterone or thyroxine to normal animals in the first two postnatal weeks increased relative numbers of chief ...

Nuclear and cytoplasmic microfilaments in the pineal chief cells of the rat
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1967The presence of identical groups of parallel microfilaments in the nucleus and in the cytoplasm of the rat epiphyseal chief cells are described. The areas of microfilaments are not surrounded by any membranes and the single filaments are about 70–80 A in diameter and vary largely in length. At higher magnification the filaments are shown to be composed

Cells Tissues Organs, 1988
The electron immunocytochemical co-localization of prochymosin and pepsinogen in chief cells mucous neck cells and transitional mucous neck/chief cells of calf fundic glands was studied using specific antisera for prochymosin and pepsinogen with a protein A-gold method.

Histochemistry, 1986
Specific PgI antibodies devoid of PgII cross reactivity have been applied to aldehyde-osmium fixed human, fundic-type, gastric mucosa investigated with the protein A-immunogold technique. PgI immunoreactivity has been detected in the homogeneous secretory granules of glandular chief cells, in bipartite granules of mucous-neck cells, in the granules of ...

The Carotid Body Chief Cell as a Paraneuron
1977The term paraneuron was proposed by Fujita (9) in a symposium on chromaffin, enterochromaffin, and related cells. Fujita listed the following characteristics as common to all the varieties of paraneurons:{1} they secrete special peptides with hormone actions; {2} they contain substances like neurotransmitters; {3} they possess membrane-bound particles ...

Gastric chief cells: Receptors and signal-transduction mechanisms
Gastroenterology, 1992Elucidation of receptors and mediators regulating gastric pepsinogen secretion has lagged behind understanding of the factors that control acid secretion. During the past decade, as a consequence of the development of in vitro models for studying the control of pepsinogen secretion at the cellular level, much information about chief cell receptors and ...
