Protective effect of corticosteroids on intercellular junction
Experimental Cell Research, 1977Abstract Actions of adrenocortical hormones on intercellular communication in salivary gland cells of Chironomus plumosus were studied by means of electrophysiological measurements. Glucocorticoids have an effect maintaining junctional communication, while mineralocorticoids have an effect blocking it.

Intercellular junctions in nerve-free hydra
Cell and Tissue Research, 1980Epithelial cells of nerve-free hydra contain septate and gap junctions. In thin sections the gap junctions are characterized by a gap of 3-4 nm. Freeze-fracture demonstrates the presence of septate junctions and two further types of structures: (i) the "E-type" or "inverted" gap junctions with particles in an "enplaque conformation appearing as a ...

The Structure and Function of Intercellular Junctions in Cancer
1976Publisher Summary Intercellular junctions are a set of structurally complex membrane components that are incorporated into the general plasma membrane at the sites of close cell-to-cell apposition. The primary function of some types of junctions, such as gap junctions, remains obscure; this is unfortunate because a considerable body of information on

Structural modifications of intercellular junctions.
Proceedings, annual meeting, Electron Microscopy Society of America, 1978Structure and function of intercellular junctions were studied under the electronmicroscope using conventional thin sectioning and freeze-etch replicas. Alterations of tight and gap junctions were analyzed 1. of exocrine pancreatic cells under cell isolation conditions and pancreatic duct ligation and 2.

Structure and function of the intercellular junctions: barrier of paracellular drug delivery.
Current pharmaceutical design, 2006The delivery of large hydrophilic molecules (i.e., peptides and proteins) across biological barriers has been hampered by the presence of tight junctions.

Intercellular Junctions in the Developing Mammalian Thymus*
Anatomia, Histologia, Embryologia, 1977AbstractLymphopoiesis in fetal thymuses of mice and rabbits was studied to try to correlate heterogeneity of lymphocytes with heterogeneity of embryonic origin. The thymuses of fetal mice of 11 to 14 days gestation and of fetal rabbits of 18 and 19 days gestation were examined by electron microscopy. At the time of earliest appearance of lymphoid cells

Intercellular Junctions in Rabbit Eye Ora Serrata
Anatomia, Histologia, Embryologia, 2006SummaryThe aim of this study was to describe and localize the intercellular junctions in the ora serrata region of albino and pigmented rabbit eyes. Eyes of albino and pigmented rabbits were fixed and processed for transmission electron microscopy. Light and electron microscope examination was carried out on semithin and ultrathin sections.

Terbinafine inhibits gap junctional intercellular communication
Toxicology and Applied Pharmacology, 2016Terbinafine is an antifungal agent that selectively inhibits fungal sterol synthesis by blocking squalene epoxidase. We evaluated the effect of terbinafine on gap junctional intercellular communication (GJIC). Fluorescence recovery after photobleaching (FRAP) and I-YFP GJIC assays revealed that terbinafine inhibits GJIC in a reversible and dose ...

Intercellular Junctions in Insect Tissues
1980Publisher Summary This chapter reviews the development of intercellular junctions in insect tissues. Studies that have been made on developing junctions show that pleated septate, smooth septate and tight junctions, being linear structures, tend to differentiate in a stepwise assembly process, while gap junctions being macular, form by “streaming” of

Intercellular junctions in the Xenopus embryo prior to gastrulation
Journal of Experimental Zoology, 1976AbstractA freeze‐fracture study of Xenopus embryos at the eight‐cell stage revealed the presence of tight junctions and small aggregations of 120 Å diameter intramembranous particles. These aggregations consited of up to ten particles and resembled forming gap junctions.
