In the anterior pituitary gland, inflammatory mediators regulate cell function through an immuno-endocrine pathway. Recent studies have shown that undifferentiated stem cells act as immunomodulators. These studies prompted us to establish a progenitor cell line from the bovine anterior pituitary gland and to detail its function. First, we localised(More)
Myostatin is involved in an inhibitor of muscular growth and differentiation. Myoblasts derived from double-muscled Japanese shorthorn cattle (DM myoblasts) with absence of functional myostatin had higher abilities to proliferate and differentiate than myoblasts derived from normal-muscled cattle (NM myoblasts). In DM myoblasts, mRNA expressions of fetal(More)
Stem/Progenitor cells in the postnatal pituitary gland are embedded in a marginal cell layer around Rathke's pouch. However, the nature and behavior of anterior pituitary progenitor cells remain unclear. We established bovine anterior pituitary progenitor cell line (BAPC)-1 from the anterior pituitary gland, which expressed stem/progenitor cell-related(More)
There are two independent serotonin (5-HT) systems of organization: one in the central nervous system and the other in the periphery. 5-HT affects feeding behavior and obesity in the central nervous system. On the other hand, peripheral 5-HT also may play an important role in obesity, as it has been reported that 5-HT regulates glucose and lipid metabolism.(More)
Recent studies show that myostatin mRNA expression is found in some regions of the brain. However, the functional significance of this is currently unknown. We therefore investigated myostatin expression and function in the brain. In this study, we used immunohistochemistry, in situ hybridization, and RT-PCR analysis to reveal that myostatin is expressed in(More)
Microfold (M) cells in the follicle-associated epithelium (FAE) of Peyer’s patches contribute to the mucosal immune response by the transcytosis of microorganisms. The mechanism by which M cells take up microorganisms, and the functional proteins by which they do this, are not clear. In order to explore one such protein, we developed a 2H5-F3 monoclonal(More)
In mice, peripheral 5-HT induces an increase in the plasma concentrations of glucose, insulin and bile acids, and a decrease in plasma triglyceride, NEFA and cholesterol concentrations. However, given the unique characteristics of the metabolism of ruminants relative to monogastric animals, the physiological role of peripheral 5-HT on glucose and lipid(More)
Neuropeptide Y (NPY), a 36-amino acid member of the pancreatic polypeptide family, was found to be present by immunohistochemistry in the bovine adenohypophysis. NPY mRNA expression was confirmed in the adenohypophysis by RT-PCR. NPY immunoreactivity was present in about 38% of adenohypophyseal cells in the pars distalis. However, NPY immunoreactive cells(More)
