A molecular relay race: sequential first-passage events to the terminal reaction centre in a cascade of diffusion controlled processes
Denis S. Grebenkov, Ralf Metzler, Gleb Oshanin
We consider a sequential cascade of molecular first-reaction events towards a terminal reaction centre in which each reaction step is controlled by diffusive motion of the particle…
A first-passage approach to diffusion-influenced reversible binding: insights into nanoscale signaling at the presynapse
Maria Reva, David A. DiGregorio, Denis S. Grebenkov
Synaptic transmission between neurons is governed by a cascade of stochastic reaction-diffusion events that lead to calcium-induced vesicle release of neurotransmitter. Since exper…
Heterogeneities Shape Passive Intracellular Transport
P. Witzel, M. Götz, Y. Lanoiselée +3
A living cell's interior is one of the most complex and intrinsically dynamic systems, providing an elaborate interplay between cytosolic crowding and ATP-driven motion, which cont…
Brownian-like deviation of neighboring cells in the early embryogenesis of the zebrafish
Juan Raphael Diaz Simoes, Denis Grebenkov, Paul Bourgine +1
We investigate cell trajectories during zebrafish early embryogenesis based on 3D+time photonic microscopy imaging data. To remove the collective flow motion and focus on fluctuati…
A model of non-Gaussian diffusion in heterogeneous media
Yann Lanoiselée, Denis S. Grebenkov
Recent progresses in single particle tracking have shown evidences of non-Gaussian distribution of displacements in living cells, both near the cellular membrane and inside the cyt…
