immunity. In mammals and other higher vertebrates, a plethora of information exists on the …

Vanadate ions, low-molecular-weight phosphate analogues, mimic most of the rapid actions
of insulin in various cell types. When administered orally to diabetic hyperglycemic rats …

High-speed microcinematography of nematocyst discharge in Hydra attenuata Pall. shows
that this specialized exocytosis, which appears to result from an increase in the intracapsular …

Opiomelanotropinergic cells in the intermediate lobe of the pituitary and in neurons in the
brain secrete at least 7 peptides related to melanocyte stimulating hormone (MSH) and β …

Mammalian cell membranes harbor several types of chloride channels, chloride-cation
symporters/cotransporters, and several classes of anion exchangers/antiporters. These …

Gold-labelled rabbit antiserum was used to demonstrate that a cuticle-degrading protease
(Pr1) is produced by Metarhizium anisopliae during penetration of host (Manduca sexta) …

Lipopolysaccharides (LPS) and the β-1, 3-glucan laminarin G, both of which specifically
activate the prophenoloxidase (proPO) activating system of crayfish haemocyte lysate, were …

When isolated chromaffin granules were aggregated by synexin (a Ca2+-binding protein
present in chromaffin and other secretory tissues) and then exposed to cis-unsaturated fatty …

Structural changes underlying exocytosis evoked by the application of endotoxin to Limulus
amebocytes were studied at the level of detail afforded by freeze-fracture and freeze …

Regulated secretion in exocrine and neuroendocrine cells occurs through exocytosis of
secretory granules and the subsequent release of stored small molecules and proteins. The …
