These results suggested that secretory vesicles act as paracrine mediators for regulation of cellular responses.
In this case, the metal precipitation occurs as intracellular granules of different types which, after being stored, are directly discharged by secretory vesicles into the lumen or by substitution of the intestinal epithelium (Hubert, 1979a; Nogarol and Fontanetti, 2010; Godoy and Fontanetti, 2010).
These results suggested that (1) the fusion of secretory vesicles from cytoplasm and apical membrane in the lacrimal gland and conjunctiva and (2) the maturation of secretory vesicles were vulnerable to cGVHD.
In order to efficiently migrate and become functionally highly active, neutrophils need to mobilize their secretory vesicles and upregulate CD11b [64].
Increases in [Ca.sup.2+] levels often lead to the release of many different kinds of stored hormones and other proteins from secretory vesicles (Kits and Mansvelder 2000).
The 14-3-3 proteins were localized in the shak region, which coincides with the localization of H+-ATPase pumps, the nucleus, and the tip of the pollen tubes, where secretory vesicles are delivered to the plasma membrane.
Cell structures called secretory vesicles have been found all along the length of the fiber in the process of fusing to the cell membrane.
Neutrophils contain primary (azurofil), secondary (specific), and tertiary (gelatinase) granules, as well as secretory vesicles [1].
e) In ultrastructural section of control group; Many mitochondria and secretory vesicles in odontoblasts (yellow), regular capillary vessels of subodontoblastic layer (red arrow) (Uranyl acetate and lead citrate staining, Bar 2 [micro]m).
Notably, in contrast to mammalian secretory vesicles, CV retain this fusion-competent or readily releasable state in vitro, even after isolation from the PM; CV thus serve as a unique tool with which to rigorously and quantitatively assess the fundamental molecular mechanisms underlying the docked or primed state and fast [Ca.sup.2+]-triggered fusion (Vogel et al., 1996; Coorssen et al., 1998, 2003; Tahara et al., 1998; Blank et al., 2001; Szule et al., 2003; Whalley et al., 2004; Churchward et al., 2005; Hibbert et al., 2006; Rogasevskaia and Coorssen, 2011; Rogasevskaia et al., 2012).
In the present study, we determined the subcellular localization of the PAFR in resting neutrophils, and our studies demonstrate that PAFRs are localized in a light membrane fraction containing plasma membranes and secretory vesicles. Mobilization data show that the cells lack an easily mobilizable PAFR pool, suggesting that the receptor is present primarily in the plasma membrane.
The presence of double-labeled A[beta]42 in the RER indicates that the catabolic proteolytic [beta] and [gamma] secretases are in the membrane of the RER and breakdown of the precursor protein APP occurs before the Golgi and secretory vesicles. Intracellular A[beta]42 may interact with the lipids in the RER to induce lipid peroxidation (toxic aldehydic products like 4-hydroxynonenal) as it does with the plasma membrane.
