Lymphocyte Crawling and Transendothelial Migration Require Chemokine Triggering of High-Affinity LFA-1 Integrin
Ziv Shulman,Vera Shinder,Eugenia Klein,Valentin Grabovsky,Orna Yeger,Erez Geron,Alessio Montresor,Matteo Bolomini-Vittori,Sara W. Feigelson,Tomas Kirchhausen,Carlo Laudanna,Guy Shakhar,Ronen Alon +12 more
TL;DR: It is proposed that shear forces exerted on HA-LFA-1 trigger adhesive and invasive filopodia at apical endothelial surfaces and thereby promote lymphocyte crawling and probing for TEM sites.

NaCl-dependent expression of amiloride-blockable Na+ channel in Xenopus oocytes
TL;DR: The previously reported regulation of transport by the dietary NaCl intake involves modulations in the level of mRNA that codes either for the Na+ channel or a posttranscriptional regulator of the channel.

Sodium-dependent inhibition of the epithelial sodium channel by an arginyl-specific reagent.
TL;DR: It was shown that the augmentation of transport induced by incubating whole cells in Ca2+-free solution involves the activation or recruitment of channels that are not vulnerable to PGO prior to incubation, and this effect is compatible with a model in which the conductive path of the channel contains a functional arginine.

Direct inhibition of epithelial Na+ channels by a pH-dependent interaction with calcium, and by other divalent ions.
TL;DR: The fact that the apical Na+ conductance in vesicles, can effectively be modulated by minor variations of the internal pH near the physiological value, raises the possibility that channels are being regulated by pH changes which alter their apparent affinity to cytoplasmic Ca2+, rather than, or in addition to changes in the cytopalasmic level of free Ca2+.
Self-suppression of biofilm formation in the cyanobacterium Synechococcus elongatus

TL;DR: A mutant of the cyanobacterium Synechococcus elongatus, which unlike the wild type, developed biofilms was identified, which suggested that the planktonic nature of the wild-type strain is a result of a self-suppression mechanism, which depends on the deposition of a factor to the extracellular milieu.
