Freeze-fracture architecture and polypeptide composition of thylakoid membranes from euploid Ricinus cells.
The freeze-fracture architecture and polypeptide composition of thylakoid membranes of euploid cells of Ricinus communis L. were examined. Electron microscopic examination of the chloroplasts of 1N 2N and 4N cells revealed little variation in the size of chloroplasts, lamellar structure and internal organization of plastids, despite increases in plastid numbers per cell observed to accompany th...
متن کاملArchitecture effects on L-selectin shedding induced by polypeptide-based multivalent ligands.
Multivalent interactions between selectins and their ligands play key roles in mediating the rolling and tethering of leukocytes in the early steps of the inflammatory response, as well as in lymphocyte circulation. L-selectin shedding, which is the proteolytic cleavage of L-selectin, can be induced by L-selectin clustering through the binding of multivalent ligands to multiple L-selectin molec...
متن کاملPancreatic polypeptide.
Pancreatic polypeptide (PP) was discovered fortuitously during the purification of insulin from birds (Kimmel et al., 1968) and later from mammals (Chance et al., 1976). PP has since been extracted and purified from several mammalian species. It contains 36 amino-acid residues and is quite distinct from other known hormonal peptides (Lin and Chance, 1974). The amino-acid sequence of the peptide...
متن کاملPancreatic Polypeptide
Pancreatic Polypeptide (PP) is a 36 amino acid peptide produced and secreted by PP cells (originally termed F cells) of the pancreas which are primarily located in the Islets of Langerhans. It is part of a family of peptides that also includes Peptide YY (PYY) and Neuropeptide Y (NPY). PP is rapidly released after a meal but remains elevated for 4-6 hours in humans with the Vagus nerve being th...
متن کاملGlucose-Dependent Insulinotropic Polypeptide
OBJECTIVE To evaluate the glucose dependency of glucose-dependent insulinotropic polypeptide (GIP) effects on insulin and glucagon release in 10 healthy male subjects ([means ± SEM] aged 23 ± 1 years, BMI 23 ± 1 kg/m(2), and HbA(1c) 5.5 ± 0.1%). RESEARCH DESIGN AND METHODS Saline or physiological doses of GIP were administered intravenously (randomized and double blinded) during 90 min of ins...
