Mucociliary clearance defects in a murine in vitro model of pneumococcal airway infection. [PDF]
PLoS ONE, 2013 Mucociliary airway clearance is an innate defense mechanism that protects the lung from harmful effects of inhaled pathogens. In order to escape mechanical clearance, airway pathogens including Streptococcus pneumoniae (pneumococcus) are thought to ...

Mouse models of polycystic kidney disease induced by defects of ciliary proteins [PDF]
BMB Reports, 2013 Polycystic kidney disease (PKD) is a common hereditarydisorder which is characterized by fluid-filled cysts in thekidney. Mutation in either PKD1, encoding polycystin-1 (PC1),or PKD2, encoding polycystin-2 (PC2), are causative genes ofPKD. Recent studies

Microfluidics for Hydrodynamics Investigations of Sand Dollar Larvae [PDF]
arXiv, 2023 The life cycle of most marine invertebrates includes a planktonic larval stage before metamorphosis to bottom-dwelling adulthood. During larval stage, ciliary-mediated activity enables feeding (capture unicellular algae) and transport of materials (oxygen) required for the larva's growth, development, and successful metamorphosis.

Vortex arrays and ciliary tangles underlie the feeding-swimming tradeoff in starfish larvae [PDF]
, 2016 Many marine invertebrates have larval stages covered in linear arrays of beating cilia, which propel the animal while simultaneously entraining planktonic prey. These bands are strongly conserved across taxa spanning four major superphyla, and they are responsible for the unusual morphologies of many invertebrate larvae.

Flow Characteristics of Chlamydomonas result in Purely Hydrodynamic Scattering [PDF]
Phys. Rev. E 98, 012603 (2018), 2018 It has long been believed that swimming eukaryotes feel solid boundaries through direct ciliary contact. Specifically, based on observations of behavior of green alga Chlamydomonas reinhardtii it has been reported that it is their "flagella [that] prevent the cell body from touching the surface" [Kantsler et al. PNAS, 2013].

The European Physical Journal E : Soft matter, 2021 Cilia are hair-like membrane protrusions that emanate from the surface of most vertebrate cells and are classified into motile and primary cilia. Motile cilia move fluid flow or propel cells, while also fulfill sensory functions.

Relationship between Ciliary Blood Flow and Aqueous Production in Rabbits
Investigative Opthalmology & Visual Science, 2003 To determine the relationship between ciliary blood flow and aqueous flow by changing the mean arterial pressure (MAP) mechanically under controlled conditions in an animal model.In anesthetized rabbits, MAP and intraocular pressure (IOP) were measured by direct cannulation. MAP was controlled with occluders placed on the aorta and vena cava.

Programmable metachronal motion of densely packed magnetic artificial cilia [PDF]
arXiv, 2023 Despite recent advances in artificial cilia technologies, the application of metachrony, which is the collective wavelike motion by cilia moving out-of-phase, has been severely hampered by difficulties in controlling densely packed artificial cilia at micrometer length scales. Moreover, there has been no direct experimental proof yet that a metachronal

Advanced Functional Materials, EarlyView.Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.
