Primary ciliary dyskinesia (PCD) is a rare heterogeneous disorder, usually inherited as an autosomal recessive condition but X-linked inheritance is also described. Abnormal ciliary function in childhood leads to neonatal respiratory distress in term infants, persistent wet cough, bronchiectasis, chronic rhinosinusitis, and hearing impairment; approximately 50% of patients have situs inversus. There is a paucity of evidence for treating PCD, hence consensus guidelines are predominantly influenced by knowledge from cystic fibrosis (CF)...

Cilia are conserved cellular structures that facilitate sensory-based processes, including those required for neuronal and kidney functions. Here, we show that the human mitogen activated kinase-15 (MAPK-15) ortholog in Caenorhabditis elegans encodes a ciliary protein. A strain harboring a mutation in the catalytic site of the kinase domain results in ciliary-specific defects in tail neurons of both hermaphrodite and male worms, manifesting in dye uptake, dendrite extension, and male mating behavior defects...

Autosomal recessive polycystic kidney disease (OMIM 263200) is a serious condition of the kidney and liver caused by mutations in a single gene, PKHD1. This gene encodes fibrocystin/polyductin (FPC, PD1), a large protein shown by in vitro studies to undergo Notch-like processing. Its cytoplasmic tail, reported to include a ciliary targeting sequence, a nuclear localization signal, and a polycystin-2 binding domain, is thought to traffic to the nucleus after cleavage. We now report a novel mouse line with a triple HA-epitope "knocked-in" to the C-terminus along with lox P sites flanking exon 67, which encodes most of the C-terminus (Pkhd1(Flox67HA))...

Respiratory tract infections (RTIs) are the most common form of infections in every age category. Recurrent respiratory tract infections (RRTIs), a specific form of RTIs, represent a typical and common problem associated with early childhood, causing high indirect and direct costs on the healthcare system. They are usually the consequence of immature immunity in children and high exposure to various respiratory pathogens. Their rational management should aim at excluding other severe chronic diseases associated with increased morbidity (e...

BACKGROUND: The ciliopathies represent an umbrella group of >50 clinical entities that share both clinical features and molecular etiology underscored by structural and functional defects of the primary cilium. Despite the advances in gene discovery, this group of entities continues to pose a diagnostic challenge, in part due to significant genetic and phenotypic heterogeneity and variability. We consulted a pediatric case from asymptomatic, non-consanguineous parents who presented as a suspected ciliopathy due to a constellation of retinal, renal, and skeletal findings...

PURPOSE: To analyze the risk factors for the development of neovascular glaucoma (NVG) of patients with choroidal melanoma after proton beam therapy (PBT). METHOD: Clinical case series, retrospective study. We evaluated 629 consecutive patients receiving proton beam therapy for the treatment of a choroidal melanoma at the oncology service at Charité, Berlin and Helmholtz-Zentrum, Berlin between 05/1998 and 11/2008 regarding the development and risk factors of NVG...

Purpose: The prevailing view is that the human retina is supplied by the central retinal artery (CRA), the short posterior ciliary arteries (SPCAs) support the choroid, and both the CRA and the SPCAs are so-called "end artery" systems. In this study, we investigate whether vascular connections among the retina, choroid, and the optic nerve head (ONH) exist, using selective cannulation and microperfusion-labeling techniques. Methods: The CRA and/or one or more of the SPCAs were selected for cannulation in 18 human donor eyes...

Ciliary neurotrophic factor (CNTF) is a promising candidate for the treatment of neurodegenerative or metabolic diseases, but suffers rapid clearance in body. Herein we constructed a new long-acting recombinant human CNTF (rhCNTF) by genetic fusion with an albumin-binding domain (ABD) through a flexible peptide linker, hoping to endow the new molecule prolonged serum circulation time by binding with endogenous human serum albumin (HSA) and then utilizing the naturally long-half-life property of HSA. This fused protein rhCNTF-ABD was expressed in Escherichia coli mainly in the soluble form and purified through a two-step chromatography, with purity of 95% and a high yield of 90-100 mg/L culture...

Primary cilia are sensory, antennae-like organelles present on the surface of many cell types. They have been involved in a variety of diseases collectively termed ciliopathies. As cilia are essential regulators of cell signaling, the composition of the ciliary membrane needs to be strictly regulated. To understand regulatory processes at the ciliary membrane, we report the targeting of a genetically engineered enzyme specifically to the ciliary membrane to allow biotinylation and identification of the membrane-associated proteome...

BACKGROUND: Expectoration of sputum can be difficult for patients with respiratory conditions such as chronic obstructive pulmonary disease, chronic bronchitis, or bronchiectasis because of the effects of decreased pulmonary function, respiratory muscle fatigue, altered sputum properties, and impaired ciliary function. We developed a new method for the vibratory stimulation of the cervical trachea and this study aimed to compare it with the Acapella (a current oscillation device) method...

Motile and non-motile (primary) cilia are nearly ubiquitous cellular organelles. The dysfunction of cilia causes diseases known as ciliopathies. The number of reported ciliopathies (currently 35) is increasing, as is the number of established (187) and candidate (241) ciliopathy-associated genes. The characterization of ciliopathy-associated proteins and phenotypes has improved our knowledge of ciliary functions. In particular, investigating ciliopathies has helped us to understand the molecular mechanisms by which the cilium-associated basal body functions in early ciliogenesis, as well as how the transition zone functions in ciliary gating, and how intraflagellar transport enables cargo trafficking and signalling...

Primary ciliary dyskinesia is an inherited disease characterized by impaired ciliary function leading to diverse clinical manifestations, including chronic sinopulmonary disease, persistent middle ear effusions, laterality defects, and infertility. Our understanding of the complex genetics and functional phenotypes of primary ciliary dyskinesia has rapidly grown, and over 35 disease-associated genes have been identified, which segregate into genes that encode axonemal motor proteins, regulatory proteins within the cilium, and cytoplasmic proteins involved in ciliary assembly...

Disruption of normal ciliary function results in a range of diseases collectively referred to as ciliopathies. Here we report a child with a phenotype that overlapped with Joubert, oral-facial-digital, and Pallister-Hall syndromes including brain, limb, and craniofacial anomalies. We performed exome-sequence analysis on a proband and both parents, filtered for putative causative variants, and Sanger-verified variants of interest. Identified variants in CLUAP1 were functionally analyzed in a Xenopus system to determine their effect on ciliary function...

BACKGROUND: The use of neurotrophic factors to treat Alzheimer's disease (AD) is hindered by their blood-brain barrier impermeability, short half-life, and severe side effects. Peptide 021 (P021) is a neurotrophic/neurogenic tetra-peptide that was derived from the most active region of the ciliary neurotrophic factor (CNTF) by epitope mapping. Admantylated glycine was added to its C-terminal to increase its blood-brain barrier permeability and decrease its degradation by exopeptidases to make it druggable...

Primary ciliary dyskinesia (PCD) is an orphan disease (MIM 244400), autosomal recessive inherited, characterized by motile ciliary dysfunction. The estimated prevalence of PCD is 1:10,000 to 1:20,000 live-born children, but true prevalence could be even higher. PCD is characterized by chronic upper and lower respiratory tract disease, infertility/ectopic pregnancy, and situs anomalies, that occur in ≈50% of PCD patients (Kartagener syndrome), and these may be associated with congenital heart abnormalities...

Primary cilia have been called "the forgotten organelle" for over 20 years. As cilia now have their own Journal and several books devoted to their study, perhaps it's time to reconsider the moniker "forgotten organelle". In fact, during the drafting of this review, 12 relevant publications have been issued- we therefore apologize in advance for any relevant work we inadvertently omitted. What purpose is yet another ciliary review? The primary goal of this review is to specifically examine the evidence for and against the hypothesized flow-sensing function of primary cilia expressed by differentiated epithelia within a kidney tubule, bringing together differing disciplines and their respective conceptual and experimental approaches...

Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare paraneoplastic intraocular disease that causes progressive visual loss in patients driven by an IgG factor associated with an underlying malignancy. Characteristic ocular findings include exudative retinal detachment, rapid cataract formation and uveal melanocytic tumours. The awareness and documentation of BDUMP has increased during the past decade, and the increasing amount of data collected demonstrates the effect of treatment with plasmapheresis and the value of diagnostic tools in BDUMP such as genetic and immunologic investigations...

Primary ciliary dyskinesia is a condition in which abnormal cilia structure or function leads to reduced mucociliary clearance and obstructive lung disease. Twenty-nine patients had lung clearance index (LCI) measured in 2009 and we attempted to perform a 5-year follow-up. Only 12 patients could be re-recruited, but in this small group LCI was stable over the 5 years, which confirms previous data showing that spirometry is also stable in these patients over the medium term. The two patients with the highest LCI in 2009 had since died, despite one having relatively preserved spirometry at the time...

Aquaporins (AQPs), a large family of membrane protein channels that facilitate transport of water and other small solutes, play important roles in physiological functions and human diseases. Up till now, 13 types of AQPs, numbered 0 through 12, have been identified in various mammalian tissues. Homologous genes for AQPs in amphibians, insects, and bacteria highlight the evolutionary conservation and, thus, the importance of these membrane channels. Many members of the AQP family are expressed in the eye. AQP1, which is a water-selective channel, is expressed in the anterior chamber (cornea, ciliary body, trabecular meshwork) and posterior chamber (retina and microvessels in choroid), controlling the fluid homeostasis in the eye...

Cholangiocytes, like most cells, express primary cilia extending from their membranes. These organelles function as antennae which detect stimuli from bile and transmit the information into cells regulating several signaling pathways involved in secretion, proliferation and apoptosis. The ability of primary cilia to detect different signals is provided by ciliary associated proteins which are expressed in its membrane. Defects in the structure and/or function of these organelles lead to cholangiociliopathies that result in cholangiocyte hyperproliferation, altered fluid secretion and absorption...
