The circadian clock regulates the “push-pull” of the molecular signaling mechanisms that arrange the rhythmic organization of the physiology to maintain cellular homeostasis. In mammals, molecular clock genes tightly arrange cellular rhythmicity.

Lattice gas cellular automata model for rippling and aggregation in myxobacteria
A lattice-gas cellular automaton (LGCA) model is used to simulate rippling and aggregation in myxobacteria. An efficient way of representing cells of different cell size, shape and orientation is presented that may be easily extended to model later ...

Human iNKT Cells Promote Protective Inflammation by Inducing Oscillating Purinergic Signaling in Monocyte-Derived DCs [PDF]
Invariant natural killer T (iNKT) cells are innate T lymphocytes that promote host defense against a variety of microbial pathogens. Whether microbial ligands are required for their protective effects remains unclear. Here, we show that iNKT cells stimulate human-monocyte-derived dendritic cells (DCs) to produce inflammatory mediators in a manner that ...

G protein-coupled receptor signalling in astrocytes in health and disease: A focus on metabotropic glutamate receptors [PDF]
Work published over the past 10–15 years has caused the neuroscience community to engage in a process of constant re-evaluation of the roles of glial cells in the mammalian central nervous system.

The role of calcium oscillations in the phenotype selection in endothelial cells
Angiogenesis is an important process in the formation and maintenance of tissues which is driven by a complex system of intracellular and intercellular signaling mechanisms.

Noise-induced Input Dependence in a Convective Unstable Dynamical System
Unidirectionally coupled dynamical system is studied by focusing on the input (or boundary) dependence. Due to convective instability, noise at an up-flow is spatially amplified to form an oscillation. The response, given by the down-flow dynamics, shows

Genetic disruption of the core circadian clock impairs hippocampus-dependent memory [PDF]
Perturbing the circadian system by electrolytically lesioning the suprachiasmatic nucleus (SCN) or varying the environmental light:dark schedule impairs memory, suggesting that memory depends on the circadian system.

Dynamic expression of Notch signaling genes in neural stem/progenitor cells
In neural stem/progenitor cells, expression of the Notch effector Hes1, a transcriptional repressor, oscillates with a period of 2-3 hours by negative feedback, and Hes1 oscillations induce the oscillatory expression of the proneural gene Neurogenin2 ...
