...Yuichi Yanagihashi; Tadao Usui; Yasushi Izumi; Shigenobu Yonemura; Motoyuki Sumida; Shoichiro Tsukita; Tadashi Uemura; Mikio Furuse Septate junctions (SJs) are the membrane specializations observed between epithelial cells in invertebrates. SJs play a crucial role in epithelial barrier function...

... and invertebrates, despite the differing molecular composition of the protective barrier. Epithelial cells also have junctions that create a paracellular diffusion barrier (tight or septate junctions). To examine whether Grh has a role in regulating such characteristics, we used an epidermal layer in the Drosophila...

...Nancy J. Lane; Stephen M. Dilworth ABSTRACT Septate junctions are found only in invertebrate tissues, and are almost ubiquitous within them. In arthropods, the two major types are the ‘pleated’ and the ‘smooth’ varieties. Using tissues from different species, including the cockroach Periplaneta...

...H. Le; B. Skaer; S. H. P. Maddrell; J. B. Harrison ABSTRACT This paper describes the structural characteristics and permeability properties of the smooth septate junctions between the upper Malpighian tubule cells of a blood-sucking bug, Rhodnius prolixus . The permeability of the paracellular...

...Bechara Kachar; Nicholas A. Christakis; Thomas S. Reese; Nancy J. Lane ABSTRACT Smooth septate junctions from the midgut of the cricket, Acheta , and the horseshoe crab, Limulus , as well as Hydra-type septate junctions from the epidermis of Hydra have been studied by freeze-fracture after direct...
