Airway ciliated cells in adult lung homeostasis and COPD
European Respiratory Review, 2023 Cilia are organelles emanating from the cell surface, consisting of an axoneme of microtubules that extends from a basal body derived from the centrioles. They are either isolated and nonmotile (primary cilia), or grouped and motile (motile cilia). Cilia

Energetics of synchronisation for model flagella and cilia [PDF]
Phys. Rev. E 103, 042419 (2021), 2021 Synchronisation is often observed in the swimming of flagellated cells, either for multiple appendages on the same organism or between the flagella of nearby cells. Beating cilia are also seen to synchronise their dynamics. In 1951, Taylor showed that the observed in-phase beating of the flagella of co-swimming spermatozoa was consistent with ...

Intrinsic and Extrinsic Factors Affecting Microtubule Dynamics in Normal and Cancer Cells
Molecules, 2020 Microtubules (MTs), highly dynamic structures composed of α- and β-tubulin heterodimers, are involved in cell movement and intracellular traffic and are essential for cell division.

ARL13B regulates Sonic hedgehog signaling from outside primary cilia
eLife, 2020 ARL13B is a regulatory GTPase highly enriched in cilia. Complete loss of Arl13b disrupts cilia architecture, protein trafficking and Sonic hedgehog signaling. To determine whether ARL13B is required within cilia, we knocked in a cilia-excluded variant of

Ependymal cilia beating induces an actin network to protect centrioles against shear stress
Nature Communications, 2018 Ependymal ciliary beating contributes to the flow of cerebrospinal fluid in the brain ventricles and these cilia resist the flow forces. Here the authors show that the assembly of a dense actin network around the centrioles is induced by cilia beating to

Identification and characterization of a novel allele of Caenorhabditis elegans bbs-7. [PDF]
PLoS ONE, 2014 Primary cilia play a role in the sensation of and response to the surrounding environment. Caenorhabditis elegans (C. elegans) have primary cilia only on the distal tips of some dendrites.

Evaluating efficiency and robustness in cilia design [PDF]
Phys. Rev. E 93, 033119 (2016), 2015 Motile cilia are used by many eukaryotic cells to transport flow. Cilia-driven flows are important to many physiological functions, yet a deep understanding of the interplay between the mechanical structure of cilia and their physiological functions in healthy and diseased conditions remains elusive.

The effects of acute hydrogen peroxide exposure on respiratory cilia motility and viability [PDF]
PeerJ, 2023 COVID-19 has seen the propagation of alternative remedies to treat respiratory disease, such as nebulization of hydrogen peroxide (H2O2). As H2O2 has known cytotoxicity, it was hypothesised that H2O2 inhalation would negatively impact respiratory cilia ...

Spontaneous phase coordination and fluid pumping in model ciliary carpets [PDF]
, 2022 Ciliated tissues such as in the mammalian lungs, brains, and reproductive tracts, are specialized to pump fluid. They generate flows by the collective activity of hundreds of thousands of individual cilia that beat in a striking metachronal wave pattern.

BioFactors, Volume 48, Issue 6, Page 1226-1249, November/December 2022., 2022 Abstract Ocular allergies are becoming more prevalent as more airborne pollutants, irritants and microbes pervade our environment. Inflammatory and allergic mediators released by dendritic and mast cells within the conjunctiva cause allergic conjunctivitis (AC), a prevalent ocular surface disorder that affects >40% of the world's human population on a ...
