Traffic jam suppresses immunity
Proteases commit microbicide hite blood cells use proteases to kill their targets, according to new results from Emer Reeves, Hiu Lu, Anthony Segal (University College, London, England), and colleagues. The findings contradict previously accepted notions that reactive oxygen species (ROSs) are the killing agents. ROSs like superoxide are produced by NADPH oxidase activity when white blood cells...
متن کاملParkinson’s Disease: A Traffic Jam?
Recent large-scale proteomic analyses of two protein kinases that are linked to Parkinson's disease have identified a remarkable convergence between their respective impacts on the phosphoproteome: activation of both LRRK2 and PINK1 leads to phosphorylation of several members of the Rab family of small GTPases, which regulate membrane trafficking.
متن کاملConsequences of a traffic jam
In This Issue In This Issue trophin, a member of the spectrin superfamily of actin-binding proteins ubiquitously expressed in human cells, helps link the actin cytoskeleton to the extracellular matrix. Galkin et al. report on page 231 that a newly developed image analysis method identifies two different modes of utrophin binding to F-actin. The findings contradict earlier studies on utrophin–ac...
متن کاملTwo-way traffic flow: Exactly solvable model of traffic jam
We study completely asymmetric two-channel exclusion processes in one dimension. It describes a two-way traffic flow with cars moving in opposite directions. The interchannel interaction makes cars slow down in the vicinity of approaching cars in the other lane. Particularly, we consider in detail the system with a finite density of cars on one lane and a single car on the other. When the inter...
متن کاملExactly solvable cellular automaton traffic jam model.
A detailed study is undertaken of the v{max}=1 limit of the cellular automaton traffic model proposed by Nagel and Paczuski [Phys. Rev. E 51, 2909 (1995)]. The model allows one to analyze the behavior of a traffic jam initiated in an otherwise freely flowing stream of traffic. By mapping onto a discrete-time queueing system, itself related to various problems encountered in lattice combinatoric...
