Role of cilia activity and surrounding viscous fluid on properties of metachronal waves [PDF]
arXiv, 2023 Large groups of active cilia collectively beat in a fluid medium as metachronal waves, essential for some microorganisms motility and for flow generation in mucociliary clearance. Several models can predict the emergence of metachronal waves, but what controls the properties of metachronal waves is still unclear.

eLife, 2023 The Reissner fiber (RF) is an acellular thread positioned in the midline of the central canal that aggregates thanks to the beating of numerous cilia from ependymal radial glial cells (ERGs) generating flow in the central canal of the spinal cord.

Combined exome and whole-genome sequencing identifies mutations in ARMC4 as a cause of primary ciliary dyskinesia with defects in the outer dynein arm [PDF]
, 2013 Primary ciliary dyskinesia (PCD) is a rare, genetically heterogeneous ciliopathy disorder affecting cilia and sperm motility. A range of ultrastructural defects of the axoneme underlie the disease, which is characterised by chronic respiratory symptoms ...

Islet primary cilia motility controls insulin secretion [PDF]
, 2022 Primary cilia are specialized cell-surface organelles that mediate sensory perception and, in contrast to motile cilia and flagella, are thought to lack motility function.

Cryo-electron tomography of motile cilia and flagella [PDF]
Cilia, 2015 Cryo-electron tomography has been a valuable tool in the analysis of 3D structures of cilia at molecular and cellular levels. It opened a way to reconstruct 3D conformations of proteins in cilia at 3-nm resolution, revealed networks of a number of component proteins in cilia, and has even allowed the study of component dynamics.

Nonlinear Dynamics of Cilia and Flagella [PDF]
Phys. Rev. E 79, 051918 (2009), 2009 Cilia and flagella are hair-like extensions of eukaryotic cells which generate oscillatory beat patterns that can propel micro-organisms and create fluid flows near cellular surfaces. The evolutionary highly conserved core of cilia and flagella consists of a cylindrical arrangement of nine microtubule doublets, called the axoneme.

Cells, 2019 Cilia are highly evolutionarily conserved, microtubule-based cell protrusions present in eukaryotic organisms from protists to humans, with the exception of fungi and higher plants.

Concurrent Actuation and Sensing in Fluid by Cilia‐Like Transducers
Advanced Intelligent Systems, 2023 Motile cilia are miniature, hair‐like organelles whose beating moves fluid in various organisms and the human body. Motile cilia are also able to sense many mechanical or fluidic cues.

Sensory functions of motile cilia and implication for bronchiectasis [PDF]
Frontiers in Bioscience, 2012 Cilia are specialized organelles that extend from the cell surface into the local environment. Cilia of the airway epithelia are motile to provide mucociliary clearance. On other cells, solitary cilia are specialized to detect chemical or mechanosensory signals.

Basal body stability and ciliogenesis requires the conserved component Poc1 [PDF]
, 2009 Centrioles are the foundation for centrosome and cilia formation. The biogenesis of centrioles is initiated by an assembly mechanism that first synthesizes the ninefold symmetrical cartwheel and subsequently leads to a stable cylindrical microtubule ...
