  journal={Zeitschrift f{\"u}r angewandte Mathematik und Physik},
Kinetic-transport equations that take into account the intracellular pathways are now considered as the correct description of bacterial chemotaxis by run and tumble. Recent mathematical studies have shown their interest and their relations to more standard models. Macroscopic equations of Keller–Segel type have been derived using parabolic scaling. Due to the randomness of receptor methylation or intracellular chemical reactions, noise occurs in the signaling pathways and affects the tumbling… Expand
Mathematical Modelling and Analysis of Fractional Diffusion Induced by Intracellular Noise
In this paper we use an individual-based model and its associated kinetic equation to study the generation of long jumps in the motion of E. coli. These models relate the run-and-tumble process toExpand
Space-time fractional diffusion in cell movement models with delay

Macroscopic limit of a kinetic model describing the switch in T cell migration modes via binary interactions
A kinetic model for such a switch in CTL migration modes is developed and its possible generalisations are expected to find applications in the study of the immune response to cancer and in other biological contexts in which switch from non-local to localised migration patterns occurs. Expand


Derivation of the bacterial run-and-tumble kinetic equation from a model with biochemical pathway
This program shows how the first class of equations can be derived from the second class with molecular content after appropriate rescaling, and how Randomness of receptor methylation events can be included and used to compute the tumbling frequency in presence of such a noise. Expand
