PY - 2019/11/12. Y1 - 2019/11/12. N2 - The nexin-dynein regulatory complex (N-DRC) in motile cilia and flagella functions as a linker between neighboring doublet microtubules, acts to stabilize the axonemal core structure, and serves as a central hub for the regulation of ciliary motility. Although the N-DRC has been studied extensively using genetic, biochemical, and structural approaches, the precise arrangement of the 11 (or more) N-DRC subunits remains unknown. Here, using cryo-electron tomography, we have compared the structure of Chlamydomonas wild-type flagella to that of strains with specific DRC subunit ...

Ciliary defects can lead to a number of human diseases. Genetic mutations compromising the proper functioning of cilia, ciliopathies, can cause chronic disorders such as primary ciliary dyskinesia (PCD), nephronophthisis or Senior-Loken syndrome. In addition, a defect of the primary cilium in the renal tube cells can lead to polycystic kidney disease (PKD). In another genetic disorder called Bardet-Biedl syndrome (BBS), the mutant gene products are the components in the basal body and cilia.[9]. Lack of functional cilia in female Fallopian tubes can cause ectopic pregnancy. A fertilized ovum may not reach the uterus if the cilia are unable to move it there. In such a case, the ovum will implant in the Fallopian tubes, causing a tubal pregnancy, the most common form of ectopic pregnancy.[28]. As noted above, epithelial sodium channels ENaC that are expressed along the length of cilia regulate fluid level surrounding the cilia. Mutations that decrease the activity of ENaC result in multisystem ...

Our study provides direct visualization of the asymmetric distribution of dynein activity and conformational switching between opposite sides of a beating flagellum. However, the nature of the switching signal(s) is still unknown. Four major models have been proposed for how the regular switching of dynein activity might be regulated, including (i) the distributor model, which proposes that a series of enzymatic and mechanical interactions between regulatory complexes [e.g., CPC, radial spokes, nexin-dynein regulatory complex (N-DRC), and I1 dynein] modulate dynein activity (23, 26); (ii) the geometric clutch model, which posits that bending-induced distortions of the axoneme change the spacing between DMTs, acting as a clutch to disengage dyneins from their DMT tracks so that they can no longer generate force (or impede interdoublet sliding) (27); (iii) the sliding-control model, which postulates collective dynein behavior and a positive feedback mechanism in which the activity of dyneins ...

Cilia and flagella have a characteristic 9 + 2 structure in which a ring of nine microtubule doublets surrounds a central pair of two microtubules and numerous associated proteins. The central pair is critical for motility, but we know little about its associated proteins and their functions. On p. 4179, Hui Zhang and David Mitchell reveal that one of these, Cpc1, is responsible for refuelling the organelle. Chlamydomonas cpc1 mutants exhibit reduced flagellar beating. The authors have cloned the Cpc1 gene and use an anti-Cpc1 antibody to show that it encodes a conserved component of a 16S complex associated with the central pair. Sequence analysis indicates that Cpc1 has an unusual adenylate kinase domain. Since adenylate kinases generate ATP from ADP, Zhang and Mitchell examined the effect of increasing the concentration of ATP on flagellar beating in cpc1 mutants: significantly, the increase suppresses the beating defect. The authors conclude that, under normal conditions, Cpc1 is needed to ...

The three were very confiding. Especially Yuri loved our company and liked to be petted. Nami was cheeky while Sora was very calm. Being an albino, Sora had severe eye problems and was almost blind which didnt seem to bother her much. Luckily eyesight is not as important to rats as it is to us humans.. All three had long rat lives. Yuri had cancer but luckily we found a good vet in Gauting, a city near our home (I grew up in Gauting). Not only did she know how to treat rats, she had some herself at a time. Shes also very friendly and committed. Yuri was the first of our rats that was treated by her and since then shes the vet we trust. Unfortunately Yuri grew another cancer a few months later. We didnt want to have Yuri suffer an operation again so we decided to have it untreated as she already was well over two years old. Eventually we had her euthanized as the cancer grew too big.. ...

TY - JOUR. T1 - The IFT-A complex regulates Shh signaling through cilia structure and membrane protein trafficking. AU - Liem, Karel F.. AU - Ashe, Alyson. AU - He, Mu. AU - Satir, Peter. AU - Moran, Jennifer. AU - Beier, David. AU - Wicking, Carol. AU - Anderson, Kathryn V.. PY - 2012/6/11. Y1 - 2012/6/11. N2 - Two intraflagellar transport (IFT) complexes, IFT-A and IFT-B, build and maintain primary cilia and are required for activity of the Sonic hedgehog (Shh) pathway. A weak allele of the IFT-A gene, Ift144, caused subtle defects in cilia structure and ectopic activation of the Shh pathway. In contrast, strong loss of IFT-A, caused by either absence of Ift144 or mutations in two IFT-A genes, blocked normal ciliogenesis and decreased Shh signaling. In strong IFT-A mutants, the Shh pathway proteins Gli2, Sufu, and Kif7 localized correctly to cilia tips, suggesting that these pathway components were trafficked by IFT-B. In contrast, the membrane proteins Arl13b, ACIII, and Smo failed to ...

The highly motile, 9 + 0 sperm axoneme of Anguilla has inner dynein arms (IDAs) but not outer dynein arms. The in situ morphology of these IDAs is shown here to be essentially identical to the IDA morphology already seen in the axonemes of Chlamydomonas, Tetrahymena and Beroe, and in the sperm tails of echinoderms and several vertebrate species. In addition, this study demonstrates: (1) that the nexin (circumferential) links are present in Anguilla and are typical; (2) that IDA1 incorporates an archway, supported by a pillar-structure; (3) that images from thin sections and whole mounts are consistent with those from replicas of rapidly-frozen specimens; and (4) that the IDA and nexin link morphology is apparently unaffected by whether the axoneme is depleted of ATP, relaxed with ATP and vanadate, or inhibited by high ATP. An attempt has been made to reconcile the emergent morphology of the IDA complex with all earlier descriptions in the literature. From a detailed comparison of the results ...

The ciliary transition zone (TZ) is a complex structure found at the cilia base. Defects in TZ assembly are associated with human ciliopathies. In most eukaryotes, three protein complexes (CEP290, NPHP, and MKS) cooperate to build the TZ. We show that in Drosophila melanogaster, mild TZ defects are observed in the absence of MKS components. In contrast, Cby and Azi1 cooperate to build the TZ by acting upstream of Cep290 and MKS components. Without Cby and Azi1, centrioles fail to form the TZ, precluding sensory cilia assembly, and no ciliary membrane cap associated with sperm ciliogenesis is made. This ciliary cap is critical to recruit the tubulin-depolymerizing kinesin Klp59D, required for regulation of axonemal growth. Our results show that Drosophila TZ assembly in sensory neurons and male germ cells involves cooperative actions of Cby and Dila. They further reveal that temporal control of membrane cap assembly by TZ components and microtubule elongation by kinesin-13 is required for axoneme ...

TY - JOUR. T1 - Three-headed outer arm dynein from Chlamydonwnas that can functionally combine with outer-arm-missing axonemes. AU - Takada, Saeko. AU - Sakakibara, Hitoshi. AU - Kamiya, Ritsu. PY - 1992/6. Y1 - 1992/6. N2 - A procedure was developed for Isolating Chlamydonzonas outer-arm dynein that can functionally combine with the axoneme of an outer-arm-missing mutant, oda1. Previous studies showed that the outer-arm dyneln of this organism, containing three heavy chains (α, β, γ), dissociates upon extraction with a high-salt-concentration buffer solution into an 18-S particle containing the α and β heavy chains and a 12-S particle containing the γ heavy chain. It was found, however, that the three heavy chains did not dissociate if the high-salt extract was centrifuged in the presence of Mg2+ the three chains constituted a single species (23-S dynein) sedimenting at about 23 S and displayed a three-headed bouquet configuration in electron micrographs. Furthermore, the 23-S dyneln had ...

Bridge-like connections between axoneme and mitochondrial derivatives of Triatoma infestans are identical to those of other Heteropterans where they have been identified as a typical characteristic of the spermatozoa of this group of insects. Whole-mount preparations revealed bridge localization in the grooves between mitochondrial cristae. Bridges occur regularly along the axoneme with a spacing of approximately 52 nm and are not in horizontal register on opposite sides of the axoneme. Shearing of flagellar organelles demonstrated strong attachment of bridges directly to the mitochondrial derivatives at one extremity, while at the other, bridges pull out connecting fibers from the axoneme (after sodium citrate treatment). © 1988 ...

If you have a question about this talk, please contact miriamh.. Abstract: New cryo-EM technologies enable to investigate protein structures in the native physiological context of the cell. We use these technologies to study the self-organized assembly of cilia, ubiquitous organelles of eukaryotic cells. Assembly of the cilium requires the rapid bidirectional intraflagellar transport (IFT) of building blocks to and from the site of assembly at its tip. This bidirectional transport is driven by the anterograde motor kinesin-2 and the retrograde motor dynein-1b, which are both bound to a large complex of 25 IFT adaptor proteins. We have recently developed a millisecond resolution 3D correlative light and electron microscopy (CLEM) approach to show that anterograde and retrograde IFT trains use separated microtubule tracks along the microtubule doublets of the cilium (Stepanek & Pigino, 2016). With this method at hand we showed that the spatial segregation of oppositely directed trains ensures a ...

Many eukaryotic cells carry cilia or flagella. These whip-like cell appendages are characterized by highly-conserved cytoskeletal elements consisting of a regular arrangement of microtubule doublets. In many cells, the regular flagellar bending is powered by molecular motors that propel the cell. It is well established that Ca2+ is key for the control of bending in many cell types from sperm to algae. Sperm are bio-machines that steer their swimming path along chemical signposts or chemoattractants, a process termed chemotaxis. The binding of chemoattractant to receptors on the flagellum triggers a signaling cascade that eventually leads to a change in Ca2+. Simultaneously, a corresponding change in the flagellar bending arises resulting in a chemotactic steering response. Previous research identified Ca2+ as a key player for flagellar motility. In particular, the concept was that flagellar bending is directly controlled by the absolute Ca2+ concentration. Studying intact sea urchin sperm ...

Investigator: Grant Turner. Mentor: Joseph Sisson, MD. Cilia are essential components of multiple organ systems. Inherited defects in ciliogenesis, the formation of cilia, are often lethal in utero, indicating a critical role for cilia in growth and development. Intraflagellar transport proteins (IFTs) are a diverse group of proteins that are essential for moving proteins on and off of the axoneme and found to have multiple important functions in the structure and function of cilia. For example, defects in IFT88 cause severe defects in the sensing cilia in the kidneys, resulting in polycystic kidney formation, and in the lung, where bronchiectasis results. While the role of IFTs in ciliogenesis has been established, the specific role IFT88 plays in airway cilia structure and function is unknown. We hypothesized that: 1) IFT88 is required for de novo ciliogenesis in vitro; and 2) IFT88 is required to translocate the methacholine receptor, which is part of a cilia motility regulator complex, from ...

The microtubule axoneme is an iconic structure in eukaryotic cell biology and the defining structure in all eukaryotic flagella (or cilia). Flagella occur in taxa spanning the breadth of eukaryotic evolution, which indicates that the organelles origin predates the radiation of extant eukaryotes from a last common ancestor. During evolution, the flagellar architecture has been subject to both elaboration and moderation. Even conservation of 9+2 architecture-the classic microtubule configuration seen in most axonemes-belies surprising variation in protein content. Classically considered as organelles of motility that support cell swimming or fast movement of material across a cell surface, it is now clear that the functions of flagella are also far broader; for instance, the involvement of flagella in sensory perception and protein secretion has recently been made evident in both protists and animals. Here, we review and discuss, in an evolutionary context, recent advances in our understanding of ...

Cilia are found on nearly every cell type in the mammalian body, and have been historically classified as either motile or immotile. Motile cilia are important for fluid and cellular movement; however, the roles of non-motile or primary cilia in most tissues remain unknown. Several genetic syndromes, called the ciliopathies, are associated with defects in cilia structure or function and have a wide range of clinical presentations. Much of what we know about the formation and maintenance of cilia comes from model systems like C. elegans and Chalmydomonas. Studies of mammalian cilia in live tissues have been hampered by difficulty visualizing them. To facilitate analyses of mammalian cilia function we generated an inducible CiliaGFP mouse by targeting mouse cDNA encoding a cilia-localized protein somatostatin receptor 3 fused to GFP (Sstr3::GFP) into the ROSA26 locus. In this system, Sstr3::GFP is expressed from the ubiquitous ROSA26 promoter after Cre mediated deletion of an upstream Neo cassette flanked

When detergent-extracted, demembranated cell models of Chlamydomonas were resuspended in reactivation solutions containing less than 10(-8) M Ca++, many models initially swam in helical paths similar to those of intact cells; others swam in circles against the surface of the slide or coverslip. With increasing time after reactivation, fewer models swam in helices and more swam in circles. This transition from helical to circular swimming was the result of a progressive inactivation of one of the axonemes; in the extreme case, one axoneme was completely inactive whereas the other beat with a normal waveform. At these low Ca++ concentrations, the inactivated axoneme was the trans-axoneme (the one farthest from the eyespot) in 70-100% of the models. At 10(-7) or 10(-6) M Ca++, cell models also proceeded from helical to circular swimming as a result of inactivation of one of the axonemes; however, under these conditions the cis-axoneme was usually the one that was inactivated. At 10(-8) M Ca++, most ...

N2 - Background: The lungs ability to trap and clear foreign particles via the mucociliary elevator is an important mechanism for protecting the lung against respirable irritants and microorganisms. Although cigarette smoke (CS) exposure and particulate inhalation are known to alter mucociliary clearance, little is known about how CS and nanoparticles (NPs) modify cilia beating at the cytoskeletal infrastructure, or axonemal, level. Methods: We used a cell-free model to introduce cigarette smoke extract (CSE) and NPs with variant size and surface chemistry to isolated axonemes and measured changes in ciliary motility. We hypothesized that CSE would alter cilia beating and that alterations in ciliary beat ...

The half-maximal inhibitory concentration (IC50) of streptavidin-dependent inhibition of flagellar motility was 0.15 µg/ml and the Hill coefficient was 2.37 (Fig. 3 D). At the IC50 concentration, the amount of streptavidin bound to BCCP tags was ∼5% of the saturating levels (Fig. S2 A), suggesting that the inhibitory effect of a streptavidin molecule bound to RS propagates along the axoneme. It is also noteworthy that the speed of the swimming cells did not show steep drop even when the concentration of streptavidin was high enough to inhibit the motility in 98% of the cells (Fig. 3 D, red). This all-or-none behavior suggests that inhibition of motility occurs when the amount of streptavidin bound to one axoneme is above a certain threshold.. To identify the axonemal dynein that is the downstream effector of the streptavidin-dependent inhibition of motility in rsp4C mutant, we created the strains oda1 rsp4C (lacking ODAs), ida3 rsp4C (lacking IDA subspecies f), and ida5 rsp4C (lacking IDA ...

Assembly of flagellar radial spoke proteins in Chlamydomonas: identification of the axoneme binding domain of radial spoke protein 3 ...

The radial spoke is known to play a role in the mechanical movement of the flagellum/cilium. For example, mutant organisms lacking properly functioning radial spokes have flagella and cilia that are immotile. Radial spokes also influence the cilium waveform; that is, the exact bending pattern the cilium repeats. How the radial spoke carries out this function is poorly understood. Radial spokes are believed to interact with both the central pair microtubules and the dynein arms, perhaps in a way that maintains the rhythmic activation of the dynein motors. For example, one of the radial spoke subunits, RSP3, is an anchor protein predicted to hold another protein called protein kinase A (PKA). PKA would theoretically then be able to activate/inactivate the adjacent dynein arms via its kinase activity. However, the identities and functions of the many radial spoke subunits are just beginning to be elucidated. ...

Cilia are microtubule-based organelles that are expressed on the surface of most cells in the mammalian body. Intraflagellar transport (IFT), the process by which cilia are formed and maintained, was first described in Chlamydomonas, and proteins required for IFT concentrate at the base of cilia, where they assemble into large protein complexes called IFT particles (Kozminski et al., 1995; Piperno and Mead, 1997). The IFT particles are trafficked along the axoneme by a heterotrimeric kinesin-II and a cytoplasmic dynein in the anterograde and retrograde directions, respectively. Cilia and flagella have diverse functions ranging from fluid and cell movement to mechanosensation and sensory perception (Davenport and Yoder, 2005; Scholey, 2003).. In mammals, Kif3a is a component of the kinesin-II motor protein complex required for cilia assembly while Ift88 (also known as Tg737 or polaris) is a core component of the IFT particle (Cole et al., 1998; Pazour et al., 2000; Taulman et al., 2001).

Probable component of the axonemal radial spoke head (By similarity). Radial spokes are regularly spaced along cilia, sperm and flagella axonemes. They consist of a thin stalk, which is attached to a subfiber of the outer doublet microtubule, and a bulbous head, which is attached to the stalk and appears to interact with the projections from the central pair of microtubules.

Cilia are microtubule based structures that can be motile or immotile, the latter being referred to as primary cilia. In contrast to motile cilia, such as those found on epithelia of the trachea, the importance of the primary cilium is relatively undefined despite their presence on most mammalian cells. Cilia are extremely complex organelles which are devoid of ribosomes, thus, proteins required for cilia assembly, maintenance, and signaling must be imported into the cilium. This occurs through a microtubule-based transport system called intraflagellar transport (IFT). Proteins involved in IFT concentrate around the basal body at the base of the cilium and assemble into complexes (IFT particles) which are moved up the cilium by a kinesin and returned by a cytoplasmic dynein. The IFT particle is thought to mediate the transport of cargo into the cilium as well as to deliver signals initiated in the cilium to the cytosol. Although the primary cilium was once thought to be a vestigial organelle, ...

In nearly all of the contexts in biology in which groups of cilia or flagella are found they exhibit some form of synchronized behaviour. Since the experimental observations of Lord Rothschild in the late 1940s and G.I. Taylors celebrated waving-sheet model, it has been a working hypothesis that synchrony is due in large part to hydrodynamic interactions between beating filaments. But it is only in the last few years that suitable methods have been developed to test this hypothesis. Those methods have led to the discovery of significant intrinsic biochemical noise in the beating of eukaryotic flagella. This stochasticity occurs at the level of individual beats, with interesting variations within the cycle, and is correlated and even recurrent, with memory extending to hundreds of beats. Possible biological origins of this behaviour will be discussed ...

The primary cilium is a small sensory organelle that is required for different aspects of embryonic development, including the formation of the heart. The structure and composition of cilia have been extensively studied, so that several markers of primary cilia have now been identified. However, the role of cilia in specific cell types remains poorly understood. We describe here a series of approaches to image primary cilia in the rodent heart or in primary cultures of cells dissociated from the heart. As the cilium is a marker of cell polarity, we also provide, for quantitative image analysis of cilium orientation, tools which are generally applicable to other types of tissues ...
