Drying-induced hydrophobic polymer collapse.
We have used computer simulation to study the collapse of a hydrophobic chain in water. We find that the mechanism of collapse is much like that of a first-order phase transition. The evaporation of water in the vicinity of the polymer provides the driving force for collapse, and the rate limiting step is the nucleation of a sufficiently large vapor bubble. The study is made possible through th...
متن کاملMembrane cytoskeleton: PIP2 pulls the strings
A recent application of optical tweezers has shown that plasma membrane phosphatidylinositol 4,5-bisphosphate (PIP(2)) levels control adhesion of the membrane bilayer to the underlying cytoskeleton, by regulated direct binding of PIP(2) to cytoskeletal proteins and/or indirect effects on cytoskeleton structure.
متن کاملGalectin-1 Pulls the Strings on VEGFR2
Anti-vascular endothelial growth factor (VEGF) cancer immunotherapy targets angiogenesis but development of resistance in patients is common. In this issue of Cell, Croci et al. identify a complex set of mechanisms by which galectin-1 prolongs cell-surface retention of VEGF receptor 2 (VEGFR2) and stimulates VEGF-independent tumor angiogenesis.
متن کاملCytomegalovirus pulls strings behind NK cells
Tyrosine kinase inhibitors (TKIs) targeting the BCRABL1 kinase have revolutionized the treatment strategy for Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) and acute lymphoblastic leukemia (ALL). Among the TKIs, dasatinib is distinctive in that it inhibits a broad spectrum of tyrosine kinases, including key regulators of immune responses [1]. In agreement with this p...
متن کاملHydrophobic coordination polymer nanoparticles and application for oil – water separation †
Having control over the chemistry of colloid surfaces has attracted the interest of scientists for many years as they play a critical role in many chemical and life science processes; by chemically modifying the surface or by adding other components one can enhance their stability and performance. Over the past decades, different experimental approaches have been developed with this aim and a v...
