Post‐Translational Modifications in Cilia and Ciliopathies

Advanced Science, EarlyView.
This review synthesizes current understanding of post‐translational modifications (PTMs) in ciliary proteins and emphasizes their roles in ciliary formation, homeostasis, and signaling. This review also discusses the implication of PTM dysregulation in ciliopathies and explores therapeutic strategies targeting PTM‐modifying enzymes.

Kinematics of the most efficient cilium [PDF]

Phys. Rev. Lett. 109, 038101 (2012), 2012
In a variety of biological processes, eukaryotic cells use cilia to transport flow. Although cilia have a remarkably conserved internal molecular structure, experimental observations report very diverse kinematics. To address this diversity, we determine numerically the kinematics and energetics of the most efficient cilium.

A Live Cell Imaging‐Compatible Bioreactor for the Interrogation of Cellular Responses to Modulated Flow Conditions

Advanced Science, EarlyView.
An open‐source, low‐cost 3D perfusion system integrating bioprinted scaffolds and live‐imaging overcomes 2D culture limitations. Modeling the cerebrospinal fluid‐filled subarachnoid space, it reveals flow‐dependent focal adhesion kinase activation in meningothelial cells, demonstrating a powerful platform for studying mechanobiology and creating ...

Artificial ciliary bundles with nano fiber tip links [PDF]

arXiv, 2015
Mechanosensory ciliary bundles in fishes are the inspiration for carefully engineered artificial flow sensors. We report the development of a new class of ultrasensitive MEMS flow sensors that mimic the intricate morphology of the ciliary bundles, including the stereocilia, tip links, and the cupula, and thereby achieve threshold detection limits that ...

Natural Toolbox–Chemical Engineering Aspect and High‐Value Applications of Janus Cellulose Nanomaterials

Advanced Science, EarlyView.
The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.

Quantitative optical coherence tomography imaging of intermediate flow defect phenotypes in ciliary physiology and pathophysiology.

Journal of Biomedical Optics, 2015
Cilia-driven fluid flow is a critical yet poorly understood aspect of pulmonary physiology. Here, we demonstrate that optical coherence tomography-based particle tracking velocimetry can be used to quantify subtle variability in cilia-driven flow ...

Hydrodynamic coupling of a cilia--mucus system in Herschel--Bulkley flows [PDF]

Journal of Fluid Mechanics, 2024, 994, pp.A8
The yield stress and shear thinning properties of mucus are identified as critical for ciliary coordination and mucus transport in human airways. We use here numerical simulations to explore the hydrodynamic coupling of cilia and mucus with these two properties using the Herschel--Bulkley model, in a lattice Boltzmann solver for the fluid flow.

Microfluidic propulsion by the metachronal beating of magnetic artificial cilia: a numerical analysis [PDF]

, 2011
In this work we study the effect of metachronal waves on the flow created by magnetically-driven plate-like artificial cilia in microchannels using numerical simulations. The simulations are performed using a coupled magneto-mechanical solid-fluid computational model that captures the physical interactions between the fluid flow, ciliary deformation ...
