On the parabolic-elliptic Keller-Segel system with signal-dependent motilities: a paradigm for global boundedness and steady states [PDF]
, 2020 This paper is concerned with a parabolic-elliptic Keller-Segel system where both diffusive and chemotactic coefficients (motility functions) depend on the chemical signal density. This system was originally proposed by Keller and Segel in \cite{KS-1971-JTB2} to describe the aggregation phase of {\it Dictyostelium discoideum} cells in response to the ...

A Critical-like Collective State Leads to Long-range Cell Communication in Dictyostelium discoideum Aggregation [PDF]
Final version (mainly different Fig. 4 and a bit less technical):
De Palo G, Yi D, Endres RG. PLoS Biol. 15(4): e1002602 (2017), 2018 The transition from single-cell to multicellular behavior is important in early development but rarely studied. The starvation-induced aggregation of the social amoeba Dictyostelium discoideum into a multicellular slug is known to result from single-cell chemotaxis towards emitted pulses of cyclic adenosine monophosphate (cAMP). However, how exactly do

Phosphorus availability regulates intracellular nucleotides in marine eukaryotic phytoplankton
Limnology and Oceanography Letters, 2017 Marine eukaryotic phytoplankton adapt to low phosphorus (P) in the oceans through a variety of stepâwise mechanisms including lipid substitution and decreased nucleic acid content.

Mechanobiology predicts raft formations triggered by ligand-receptor activity across the cell membrane [PDF]
, 2020 Clustering of ligand-binding receptors of different types on thickened isles of the cell membrane, namely lipid rafts, is an experimentally observed phenomenon. Although its influence on cell response is deeply investigated, the role of the coupling between mechanical processes and multiphysics involving the active receptors and the surrounding lipid ...
