Long time behavior of the solution to a chemotaxis system with nonlinear indirect signal production and logistic source

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
This paper is devoted to studying the following quasilinear parabolic-elliptic-elliptic chemotaxis system \begin{equation*} \begin{cases} u_{t}=\nabla\cdot(\varphi(u)\nabla u-\psi(u)\nabla v)+au-bu^{\gamma},\ &\ \ x\in \Omega, \ t>0,\\[2.5mm] 0 ...

Existence of global solutions to chemotaxis fluid system with logistic source

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We establish the existence of global solutions and $L^q$ time-decay of a three dimensional chemotaxis system with chemoattractant and repellent. We show the existence of global solutions by the energy method.

Boundedness and global solvability for a chemotaxis-haptotaxis model with p-Laplacian diffusion

open access: yesElectronic Journal of Differential Equations, 2020
We consider a chemotaxis-haptotaxis system with $p$-Laplacian diffusion in three dimensional bounded domains. It is asserted that for any p>2, under the appropriate assumptions, the chemotaxis-haptotaxis system admits a global bounded weak ...

Multiple CheY Proteins Control Surface-Associated Lifestyles of Azospirillum brasilense

open access: yesFrontiers in Microbiology, 2021
Bacterial chemotaxis is the directed movement of motile bacteria in gradients of chemoeffectors. This behavior is mediated by dedicated signal transduction pathways that couple environment sensing with changes in the direction of rotation of flagellar ...

Bovine neutrophil chemotaxis to Listeria monocytogenes in neurolisteriosis depends on microglia-released rather than bacterial factors

open access: yesJournal of Neuroinflammation, 2022
Background Listeria monocytogenes (Lm) is a bacterial pathogen of major concern for humans and ruminants due to its neuroinvasive potential and its ability to cause deadly encephalitis (neurolisteriosis).

A quasi-linear parabolic system of chemotaxis

open access: yesAbstract and Applied Analysis, 2006
We consider a quasi-linear parabolic system with respect to unknown functions u and v on a bounded domain of n-dimensional Euclidean space. We assume that the diffusion coefficient of u is a positive smooth function A(u), and that the diffusion ...

Uniform boundedness of solutions for a predator-prey system with diffusion and chemotaxis

open access: yesComptes Rendus. Mathématique, 2020
In this Note we study a nonlinear system of reaction-diffusion differential equations consisting of an ordinary differential equation coupled to a fully parabolic chemotaxis system. This system constitutes a mathematical model for the evolution of a prey-

Mimic Nature Using Chemotaxis of Ionic Liquid Microdroplets for Drug Delivery Purposes

open access: yesMolecules, 2022
Due to the growing prevalence of incurable diseases, such as cancer, worldwide, nowadays, the development of smart drug delivery systems is an inevitable necessity. Chemotaxis-driven movement of ionic liquid microdroplets containing therapeutic compounds

Distinct Chemotaxis Protein Paralogs Assemble into Chemoreceptor Signaling Arrays To Coordinate Signaling Output

open access: yesmBio, 2019
Most chemotactic motile bacteria possess multiple chemotaxis signaling systems, the functions of which are not well characterized. Chemotaxis signaling is initiated by chemoreceptors that assemble as large arrays, together with chemotaxis coupling ...
