Smoking is associated with shortened airway cilia. [PDF]
PLoS ONE, 2009 BACKGROUND:Whereas cilia damage and reduced cilia beat frequency have been implicated as causative of reduced mucociliary clearance in smokers, theoretically mucociliary clearance could also be affected by cilia length.

Metachronal motion of artificial magnetic cilia [PDF]
Soft Matter, 2018,14, 3689-3693, 2018 Organisms use hair-like cilia that beat in a metachronal fashion to actively transport fluid and suspended particles. Metachronal motion emerges due to a phase difference between beating cycles of neighboring cilia and appears as traveling waves propagating along ciliary carpet.

Template-Free Preparation of Thermoresponsive Mag-netic Cilia Compatible with Biological Conditions [PDF]
Journal of Physical Chemistry C 124 (47), 26068 - 26075 (2020), 2020 Bio-inspired materials are commonly used in the development of functional devices. The fabrication of artificial cilia mimicking the biological functions has emerged as a promising strategy for fluid manipulation in miniaturized systems. In this study, we propose a different physicochemical insight for the preparation of magnetic cilia based on the ...

Microfluidic pumping using artificial magnetic cilia [PDF]
. Microsystems & Nanoengineering (2018) 4:11, 2018 One of the vital functions of naturally occurring cilia is fluid transport. Biological cilia use spatially asymmetric strokes to generate a net fluid flow that can be utilized for feeding, swimming, and other functions. Biomimetic synthetic cilia with similar asymmetric beating can be useful for fluid manipulations in lab-on-chip devices. In this paper,

Coordination of Cilia Movements in Multi-Ciliated Cells
Journal of Developmental Biology, 2022 Multiple motile cilia are formed at the apical surface of multi-ciliated cells in the epithelium of the oviduct or the fallopian tube, the trachea, and the ventricle of the brain. Those cilia beat unidirectionally along the tissue axis, and this provides

Developmental Dynamics, Volume 251, Issue 12, Page 1968-1981, December 2022., 2022 Abstract Background Injury response is key to successful regeneration. Yet, transcriptome analyses of injury response were performed only on a handful of regenerative organisms. Here, we studied the injury response of the solitary ascidian Polycarpa mytiligera, an emerging model system, capable of regenerating any body part.

Diverged morphology changes of astrocytic and neuronal primary cilia under reactive insults
Molecular Brain, 2020 Primary cilia are centriole-derived sensory organelles that are present in most mammalian cells, including astrocytes and neurons. Evidence is emerging that astrocyte and neuronal primary cilia demonstrate a dichotomy in the mature mouse brain.

Neuronal cilia in energy homeostasis
Frontiers in Cell and Developmental Biology, 2022 A subset of genetic disorders termed ciliopathies are associated with obesity. The mechanisms behind cilia dysfunction and altered energy homeostasis in these syndromes are complex and likely involve deficits in both development and adult homeostasis ...

Frontiers in Cellular Neuroscience, 2019 In the adult mammalian brain, the apical surface of the subependymal zone (SEZ) is covered by many motile ependymal cilia and a few primary cilia originating from rare intermingled neural stem cells (NSCs).

Role of spatial heterogeneity on the collective dynamics of cilia beating in a minimal 1D model [PDF]
Phys. Rev. E 97, 012403 (2018), 2017 Cilia are elastic hairlike protuberances of the cell membrane found in various unicellular organisms and in several tissues of most living organisms. In some tissues such as the airway tissues of the lung, the coordinated beating of cilia induce a fluid flow of crucial importance as it allows the continuous cleaning of our bronchia, known as ...
