Relation between chemotaxis and consumption of amino acids in bacteria
Molecular Microbiology, 2015 Chemotaxis enables bacteria to navigate chemical gradients in their environment, accumulating toward high concentrations of attractants and avoiding high concentrations of repellents.

Advanced Science, EarlyView.Women with overweight or obesity follow intended isocaloric early and late time‐restricted eating (TRE) in a crossover trial. Shotgun plasma lipidomics reveals no significant differences between interventions, but identify pronounced lipid changes—including reductions in ceramides and phosphatidylcholines—within the early TRE.

Integration of the Second Messenger c-di-GMP into the Chemotactic Signaling Pathway
mBio, 2013 Elevated intracellular levels of the bacterial second messenger c-di-GMP are known to suppress motility and promote sessility. Bacterial chemotaxis guides motile cells in gradients of attractants and repellents over broad concentration ranges, thus ...

Advanced Science, EarlyView.The mechanism of secondary cognitive impairment following AKI. When renal ischemic injury progresses to fibrosis, renal fibroblasts and damaged tubular cells secrete MDK, which circulates through the bloodstream, crosses the damaged BBB, and accumulates in the hippocampus tissue (an area crucial for learning and memory).

Stabilization in a chemotaxis model for tumor invasion
, 2015 This paper deals with the chemotaxis system \[ \begin{cases} u_t=\Delta u - \nabla \cdot (u\nabla v), \qquad x\in \Omega, \ t>0, \\ v_t=\Delta v + wz, \qquad x\in \Omega, \ t>0, \\ w_t=-wz, \qquad x\in \Omega, \ t>0, \\ z_t=\Delta z - z +

LEUKOCYTE LOCOMOTION AND CHEMOTAXIS
Journal of Experimental Medicine, 1973 Polymorphonuclear leukocyte (PMN) locomotion and chemotaxis have been evaluated by direct microscopic observation of individual cells in thin slide-cover slip preparations, and also by observations on populations of cells migrating into a Millipore ...

Single‐Cell RNA Sequencing of Thyroid Tissues Reveals Pathogenesis of Graves' Disease
Advanced Science, EarlyView.Using single‐cell RNA sequencing and TCR profiling, this study constructed an immune cell atlas in thyroid tissue of Graves’ disease (GD), revealing dominant IFN‐γ‐secreting CD4+ T cells, expanded Tph and CD11c+ B cells, and enriched T/NK cells. Notably, GD thyroid follicular cells (TFCs) activated γδ T cells, which recruited cDC1 cells, suggesting a ...
