Lattice ultrasensitivity amplifies signals in E. coli without fine-tuning [PDF]

open access: yesarXiv
The E. coli chemosensory lattice, consisting of receptors, kinases, and adaptor proteins, is an important test case for biochemical signal processing. Kinase output is characterized by precise adaptation to a wide range of background ligand levels and large gain in response to small relative changes in concentration.

Neutrophils in cancer: At the crucial crossroads of anti‐tumor and pro‐tumor

open access: yesCancer Communications, EarlyView.
Abstract Neutrophils are important components of the immune system and play a key role in defending against pathogenic infections and responding to inflammatory cues, including cancer. Their dysregulation indicates potential disease risk factors. However, their functional importance in disease progression has often been underestimated due to their ...

Methods for Controlling Small GTPase Activity

open access: yesChemBioChem, Accepted Article.
Small GTPases comprise a diverse class of signaling proteins in mammalian cells and regulate a variety of cellular processes such as cell growth, cell movement, vesicle formation, and nuclear transport. Due to their involvement in critical cellular pathways, changes in the activation state of small GTPases due to genetic mutations or alterations in ...
