Exploration into the spatial and temporal mechanisms of bacterial polarity.
The recognition of bacterial asymmetry is not new: the first high-resolution microscopy studies revealed that bacteria come in a multitude of shapes and sometimes carry asymmetrically localized external structures such as flagella on the cell surface. Even so, the idea that bacteria could have an inherent overall polarity, which affects not only their outer appearance but also many of their vit...
متن کاملMglB Fills a GAP in Bacterial Polarity and Motility
Bacteria exemplify—in miniature and simplified form—many of the processes found in more complex, eukaryotic cells. For example, like their eukaryotic cousins, motile bacteria exhibit polarized morphologies: their front and back ends are distinguished by different concentrations of proteins and specialized cellular structures like pili or flagella. And, just as motile eukaryotic cells can reorga...
متن کاملAn Ising model of transcription polarity in bacterial chromosomes
Bacterial genes form clusters of the same transcription polarity and typically exhibit a preference to be coded on the leading strand of replication. An Ising model is proposed to quantify these two phenomena by analogy to the behavior of magnetic dipoles (spins) in a one-dimensional lattice. Corresponding to magnetic forces that co-orient adjacent spins and align them with an externally applie...
متن کاملWiener Polarity Index of Tensor Product of Graphs
Mathematical chemistry is a branch of theoretical chemistry for discussion and prediction of the molecular structure using mathematical methods without necessarily referring to quantum mechanics. In theoretical chemistry, distance-based molecular structure descriptors are used for modeling physical, pharmacologic, biological and other properties of chemical compounds. The Wiener Polarity index ...
متن کاملCystic fibrosis airway epithelial cell polarity and bacterial flagellin determine host response to Pseudomonas aeruginosa.
The role of epithelial polarity and bacterial factors in the control of the innate immune response of airway epithelial cells to Pseudomonas aeruginosa PAK was investigated using a human, nasal cystic fibrosis (DeltaF508/DeltaF508) epithelial cell line CF15 grown as confluent layers on permeable supports. Addition of PAK to the basal surface of CF15 layers caused significant expression changes ...
