Frontiers in Microbiology, 2019 The second messenger cyclic-di-GMP (c-di-GMP) is a critical regulator of biofilm formation in the plant pathogen Erwinia amylovora. Phosphodiesterase (PDE) enzymes are responsible for the degradation of intracellular c-di-GMP.

Lytic transglycosylases RlpA and MltC assist in Vibrio cholerae daughter cell separation
bioRxiv, 2019 The cell wall is a crucial structural feature in the vast majority of bacteria and comprises a rigid, covalently closed, mesh-like network of peptidoglycan (PG) strands.

Tripartite phase separation of two signal effectors with vesicles priming B cell responsiveness. [PDF]
, 2020 Antibody-mediated immune responses rely on antigen recognition by the B cell antigen receptor (BCR) and the proper engagement of its intracellular signal effector proteins.

On cell separation with topographically engineered surfaces [PDF]
Biointerphases, 2013 Background Topographical modifications of the surface influence several cell functions and can be exploited to modulate cellular activities such as adhesion, migration and proliferation. These complex interactions are cell-type specific, therefore engineered substrates featuring patterns of two or more different ...

Microfluidic Devices for Blood Fractionation
Micromachines, 2011 Blood, a complex biological fluid, comprises 45% cellular components suspended in protein rich plasma. These different hematologic components perform distinct functions in vivo and thus the ability to efficiently fractionate blood into its individual ...

WNK kinases sense molecular crowding and rescue cell volume via phase separation
Cell, 2022 When challenged by hypertonicity, dehydrated cells must defend their volume to survive. This process requires the phosphorylation-dependent regulation of SLC12 cation chloride transporters by WNK kinases, but how these kinases are activated by cell ...

Cell decision-making through the lens of Bayesian learning [PDF]
, 2023 Cell decision-making refers to the process by which cells gather information from their local microenvironment and regulate their internal states to create appropriate responses. Microenvironmental cell sensing plays a key role in this process. Our hypothesis is that cell decision-making regulation is dictated by Bayesian learning.

Pair separation of magnetic elements in the quiet Sun [PDF]
, 2014 The dynamic properties of the quiet Sun photosphere can be investigated by analyzing the pair dispersion of small-scale magnetic fields (i.e., magnetic elements). By using $25$ hr-long Hinode magnetograms at high spatial resolution ($0".3$), we tracked

Phase Separation in Cell Division
Molecular Cell, 2020 Cell division requires the assembly and organization of a microtubule spindle for the proper separation of chromosomes in mitosis and meiosis. Phase separation is an emerging paradigm for understanding spatial and temporal regulation of a variety of cellular processes, including cell division.
