An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (From Adams et al., Principles of Neurology, 6th ed, pp764-5)

The intracellular functions of lysosomes depend on their lytic potential. The single unit membrane of the lysosome acts as a barrier between the enzymes enclosed in the lysosome and the external substrate. The activity of the enzymes contained in lysosomes is limited or nil unless the vesicle in which they are enclosed is ruptured. Such rupture is supposed to be under metabolic (hormonal) control.

Basolateral localization of fiber receptors limits adenovirus infection from the apical surface of airway epithelia. (1/298)

Recent identification of two receptors for the adenovirus fiber protein, coxsackie B and adenovirus type 2 and 5 receptor (CAR), and the major histocompatibility complex (MHC) Class I alpha-2 domain allows the molecular basis of adenoviral infection to be investigated. Earlier work has shown that human airway epithelia are resistant to infection by adenovirus. Therefore, we examined the expression and localization of CAR and MHC Class I in an in vitro model of well differentiated, ciliated human airway epithelia. We found that airway epithelia express CAR and MHC Class I. However, neither receptor was present in the apical membrane; instead, both were polarized to the basolateral membrane. These findings explain the relative resistance to adenovirus infection from the apical surface. In contrast, when the virus was applied to the basolateral surface, gene transfer was much more efficient because of an interaction of adenovirus fiber with its receptors. In addition, when the integrity of the tight junctions was transiently disrupted, apically applied adenovirus gained access to the basolateral surface and enhanced gene transfer. These data suggest that the receptors required for efficient infection are not available on the apical surface, and interventions that allow access to the basolateral space where fiber receptors are located increase gene transfer efficiency.  (+info)

The human HLA-A*0201 allele, expressed in hamster cells, is not a high-affinity receptor for adenovirus type 5 fiber. (2/298)

The coxsackie B virus and adenovirus receptor (CAR) and the major histocompatibility complex (MHC) class I alpha2 domain have been identified as high-affinity cell receptors for adenovirus type 5 (Ad5) fiber. In this study we show that CAR but not MHC class I allele HLA-A*0201 binds to Ad5 with high affinity when expressed on hamster cells. When both receptors are coexpressed on the cell surface of hamster cells, Ad5 fiber bind to a single high-affinity receptor, which is CAR.  (+info)

Maturation of dendritic cells accompanies high-efficiency gene transfer by a CD40-targeted adenoviral vector. (3/298)

Important therapeutic applications of genetically modified dendritic cells (DC) have been proposed; however, current vector systems have demonstrated only limited gene delivery efficacy to this cell type. By means of bispecific Abs, we have dramatically enhanced gene transfer to monocyte derived DC (MDDC) by retargeting adenoviral (Ad) vectors to a marker expressed on DC, CD40. Adenovirus targeted to CD40 demonstrated dramatic improvements in gene transfer relative to untargeted Ad vectors. Fundamental to the novelty of this system is the capacity of the vector itself to modulate the immunological status of the MDDC. This vector induces DC maturation as demonstrated phenotypically by increased expression of CD83, MHC, and costimulatory molecules, as well as functionally by production of IL-12 and an enhanced allostimulatory capacity in a MLR. In comparing this vector to other Ad-based gene transfer systems, we have illustrated that the features of DC maturation are not a function of the Ad particle, but rather a consequence of targeting to the CD40 marker. This vector approach may thus mediate not only high-efficiency gene delivery but also serve a proactive role in DC activation that could ultimately strengthen the utility of this vector for immunotherapy strategies.  (+info)

Fibroblast growth factor 2 retargeted adenovirus has redirected cellular tropism: evidence for reduced toxicity and enhanced antitumor activity in mice. (4/298)

Adenovirus (Ad) have been used as vectors to deliver genes to a wide variety of tissues. Despite achieving high expression levels in vivo, Ad vectors display normal tissue toxicity, transient expression, and antivector immune responses that limit therapeutic potential. To circumvent these problems, several retargeting strategies to abrogate native tropism and redirect Ad uptake through defined receptors have been attempted. Despite success in cell culture, in vivo results have generally not shown sufficient selectivity for target tissues. We have previously identified (C. K. Goldman et al., Cancer Res., 57: 1447-1451, 1997) the fibroblast growth factor (FGF) ligand and receptor families as conferring sufficient specificity and binding affinity to be useful for targeting DNA in vivo. In the present studies, we retargeted Ad using basic FGF (FGF2) as a targeting ligand. Cellular uptake is redirected through high-affinity FGF receptors (FGFRs) and not the more ubiquitous lower-affinity Ad receptors. Initial in vitro experiments demonstrated a 10- to 100-fold increase in gene expression in numerous FGFR positive (FGFR+) cell lines using FGF2-Ad when compared with Ad. To determine whether increased selectivity could be detected in vivo, FGF2-Ad was administered i.v. to normal mice. FGF2-Ad demonstrates markedly decreased hepatic toxicity and liver transgene expression compared with Ad treatment. Importantly, FGF2-Ad encoding the herpes simplex virus thymidine kinase (TK) gene transduces Ad-resistant FGFR+ tumor cells both ex vivo and in vivo, which results in substantially enhanced survival (180-260%) when the prodrug ganciclovir is administered. Because FGFRs are up-regulated on many types of malignant or injured cells, this broadly useful method to redirect native Ad tropism and to increase the potency of gene expression may offer significant therapeutic advantages.  (+info)

Molecular determinants of adenovirus serotype 5 fibre binding to its cellular receptor CAR. (5/298)

Adenovirus (Ad) tropism is mediated in part through the fibre protein. The common coxsackie B virus and Ad receptor (CAR) was recently identified as the major receptor for subgroup C Ad serotype 5 (Ad5) and serotype 2 (Ad2) fibres. Effects of mutations in the Ad5 fibre gene were studied to assess domains of the fibre capsomer that could alter virus tropism without altering virus assembly and replication. All mutants that accumulated as fibre monomers failed to assemble with a penton base and proved lethal for Ad5 which suggests that the absence of infectious virions resulted in part from a defect in fibre penton base assembly. Cell binding capacity of all fibre mutants was investigated in cell binding competition experiments with adenovirions using CHO-CAR cells (CHO cells that have been transfected with CAR cDNA and express functional CAR). The results suggest that the R-sheet of the Ad5 fibre knob monomer contains binding motifs for CAR and that beta-strands E and F, or a region close to them, may also be involved in receptor recognition.  (+info)

Expression of the coxsackievirus and adenovirus receptor in cultured human umbilical vein endothelial cells: regulation in response to cell density. (6/298)

Primary cultures of human umbilical vein endothelial cells (HUVEC) express the human coxsackievirus and adenovirus receptor (HCAR). Whereas HCAR expression in HeLa cells was constant with respect to cell density, HCAR expression in HUVEC increased with culture confluence. HCAR expression in HUVEC was not quantitatively altered by infection with coxsackievirus B.  (+info)

Picornavirus receptor down-regulation by plasminogen activator inhibitor type 2. (7/298)

Therapeutic interference with virus-cell surface receptor interactions represents a viable antiviral strategy. Here we demonstrate that cytoplasmic expression of the serine protease inhibitor (serpin), plasminogen activator inhibitor type 2 (PAI-2), affords a high level of protection from lytic infection by multiple human picornaviruses. The antiviral action of PAI-2 was mediated primarily through transcriptional down-regulation of the following virus receptors: intercellular adhesion molecule 1 (ICAM-1, a cellular receptor for the major group of rhinoviruses), decay-accelerating factor (a cellular receptor for echoviruses and coxsackieviruses), and to a lesser extent the coxsackie-adenovirus receptor protein (a cellular receptor for group B coxsackieviruses and group C adenoviruses). Expression of related cell surface receptors, including membrane cofactor protein and the poliovirus receptor, remained unaffected. These findings suggest that PAI-2 and/or related serpins may form the basis of novel antiviral strategies against picornavirus infections and also therapeutic interventions against ICAM-1-mediated respiratory inflammation.  (+info)

Coxsackie and adenovirus receptor (CAR)-dependent and major histocompatibility complex (MHC) class I-independent uptake of recombinant adenoviruses into human tumour cells. (8/298)

The role of two receptors, previously proposed to mediate the entry of adenoviruses into human cells, the coxsackie and adenovirus receptor (CAR) and the major histocompatibility complex (MHC) class I heavy chain has been investigated. The expression of MHC class I in many tumours is reduced or absent, therefore if this were a means by which adenoviruses gained entry into cells, it would have important implications for their application in cancer treatment. In order to determine if MHC class I heavy chain is involved in adenovirus type 5 (Ad5) uptake, the binding of recombinant Ad5 fibre knob domain (which mediates viral attachment) to human cell lines that had greatly different levels of surface MHC class I was studied. We also created derivatives of a non-permissive Chinese hamster ovary (CHO) cell line that expressed human class I (HLA-A2) and found that these cells did not bind fibre or take up virus. In addition, the extracellular domain of CAR was expressed in E. coli and used to generate a polyclonal anti-CAR antibody. This antibody blocked both 125I labelled fibre knob binding and virus uptake. Thus CAR, and not MHC class I, is a receptor for human adenoviruses in cultured tumour cells. Tissue CAR levels may therefore be an important factor in the efficiency of adenovirus-mediated gene therapy.  (+info)

Subgroup C adenoviruses, including serotypes 2 and 5, from which most therapeutic adenoviruses are derived, rely on CAR as the primary binding site on the host cell. This receptor has been shown to be crucial for sufficient virus uptake (22) . In cancer cells, however, CAR expression is frequently lost, especially in highly malignant cancer cell lines, leading to a significant decrease in adenovirus uptake (5 , 6) . Our own observations are in agreement with these reports: we frequently found reduced CAR expression at the cell surface in high-grade primary liver cancer and metastases of colorectal cancer. 4 This study investigates the molecular mechanisms involved in reducing CAR expression in cancer cells and explores the possibility of pharmacologically manipulating CAR expression levels.. Increasing evidence exists for a potential physiological role of CAR as a cell adhesion molecule. CAR forms homodimers, was found to physically interact with the tight-junction protein ZO-1, and participates ...
Adenovirus serotype 5 (Ad5) is widely used as an oncolytic agent for cancer therapy. However, its infectivity is highly dependent on the expression level of coxsackievirus-adenovirus receptor (CAR) on the surface of tumor cells. We engineered Ad5 virus with the protein transduction domain (PTD) from the HIV-1 Tat protein (Tat-PTD) inserted in the hypervariable region 5 (HVR5) of the hexon protein in the virus capsid. Tat-PTD-modified Ad5 shows a dramatically increased transduction level of CAR-negative cells and bypassed fiber-mediated transduction. It also overcomes the fiber-masking problem, which is caused by release of excess fiber proteins from infected cells. To achieve specific viral replication in neuroblastoma and neuroendocrine tumor cells, we identified the secretogranin III (SCG3) promoter and constructed an adenovirus Ad5PTD(ASH1-SCG3-E1A) wherein E1A gene expression is controlled by the SCG3 promoter and the achaete-scute complex homolog 1 (ASH1) enhancer. This virus shows ...

Adenovirus binds to mammalian cellular material via conversation of fiber with the coxsackie-adenovirus receptor (CAR). the monomeric proteins. In addition, the trimerized sCAR protein without focusing on ligands efficiently clogged liver gene transfer in normal C57BL/6 mice. However, addition of either ligand failed to retarget the liver in vivo. One explanation may be the large complex size, which serves to decrease the bioavailability of the trimeric sCAR-adenovirus complexes. In summary, we have exhibited that trimerization of sCAR proteins can significantly improve the potency of this focusing on approach in altering vector tropism in vitro and allow the efficient blocking of liver gene transfer in vivo. Adenoviral vectors efficiently transduce a wide variety of cell types, which is one reason why they are prominent gene transfer vehicles in the field of gene therapy. However, systemic administration of vector leads to widespread distribution in tissue, which is not favorable if the desired ...
Photo: (Logo: The new research findings demonstrate that cardiac ischemia plays an important role in adenovector gene transfection (delivery) in mammalian hearts. Based on this understanding, using a standard balloon angioplasty catheter, researchers have developed and tested a new method to induce transient ischemia during a non-surgical interventional cardiac procedure, which when coupled with the infusion of nitroglycerin, boosts the delivery (cell transfection) of an adenovector gene construct into heart cells. The increase in adenovector-based gene transfection with the new technique is over two orders of magnitude (,100 fold).. Cardiums new method of adenovector delivery takes advantage of the findings that transient ischemia appears to alter the permeability barrier of the vascular endothelium and may expose the blood to the coxsackie-adenovirus receptor mediating adenovector ...

Abstract Background Viruses bind to specific cellular receptors in order to infect their hosts. The specific receptors a virus uses are important factors in determining host range, cellular tropism, and pathogenesis. For adenovirus, the existing model of entry requires two receptor interactions. First, the viral fiber protein binds Coxsackie and Adenovirus Receptor (CAR), its primary cellular receptor, which docks the virus to the cell surface. Next, viral penton base engages cellular integrins, coreceptors thought to be required exclusively for internalization and not contributing to binding. However, a number of studies reporting data which conflicts with this simple model have been published. These observations have led us to question the proposed two-step model for adenovirus infection. Results In this study we report that cells which express little to no CAR can be efficiently transduced by adenovirus. Using competition experiments between whole virus and soluble viral fiber protein or ...

Author Summary Mice with homozygous deletion of the calcium-sensing receptor (CaR) mimic the syndrome of neonatal severe hyperparathyroidism (NSHPT) in humans with very high circulating parathyroid hormone (PTH) and severe life-threatening hypercalcemia. To determine effects of CaR deficiency on skeletal development and interactions between CaR and 1,25(OH)2D3 or PTH on calcium and skeletal homeostasis, we compared the skeletal phenotypes of homozygous CaR-deficient mice to those of double homozygous CaR- and 1,25(OH)2D3-deficient mice or those of double homozygous CaR- and PTH-deficient mice. CaR-deficient mice had hypercalcemia, hypophosphatemia, hyperparathyroidism, severe skeletal growth retardation, and abnormalities; and most died within 2 weeks of age. Deletion of 1,25(OH)2D3 in CaR-deficient mice resulted in a longer lifespan, normocalcemia, lower serum phosphorus, greater elevation in PTH, and slight improvement in skeletal growth. Deletion of PTH in CaR-deficient mice resulted in rescue of
We have previously reported that RAS-MEK (Cancer Res. 2003 May 1;63(9):2088-95) and TGF-β (Cancer Res. 2006 Feb 1;66(3):1648-57) signaling negatively regulate coxsackie virus and adenovirus receptor (CAR) cell-surface expression and adenovirus uptake. In the case of TGF-β, down-regulation of CAR occurred in context of epithelial-to-mesenchymal transition (EMT), a process associated with transcriptional repression of E-cadherin by, for instance, the E2 box-binding factors Snail, Slug, SIP1 or ZEB1. While EMT is crucial in embryonic development, it has been proposed to contribute to the formation of invasive and metastatic carcinomas by reducing cell-cell contacts and increasing cell migration.. ...
Abstract: : Purpose:Currently a phase I clinical trial of adenoviral vector is now underway for intraocular neovascularization. We have previously reported that eyes with laser photocoagulation (PC) and photodynamic therapy increased and sustained transduction in the area of the treatment, which are already established for the treatment of retinal and/or choroidal neovascularization (Anzai K, et al.

Methods:Five C57/BL6 mice received no treatment or fundus PC with 532 nm diode laser. Twenty-four hours after the treatment eyes were enucleated and total RNA was extracted from laser photocoagulated retina and choroid. Samples were processed for qRT-PCR (Prism 7700, Applied Biosystems) to quantify mRNA expression of coxsackie adenovirus receptor (CAR) and integrins αV, ß3 and ß5, which have been shown to play a role in cell surface interaction and ...

According to preliminary data from a small phase I study, using chimeric antigen receptor (CAR) T cells to target mesothelin in solid tumors is both feasible and safe. The results were reported by Janos Tanyi, MD, PhD, a gynecologic oncologist at the University of Pennsylvania School of Medicine, at the American Association for Cancer Research Annual Meeting 2015 in Philadelphia, PA, April 18-22.. CAR T-cell therapy involves genetically engineering a patients T cells to recognize and destroy specific antigens on tumor cells-in this case, mesothelin, which is present in a range of tumor types, including gastric and esophageal cancers. Tanyi and his colleagues had previously delivered CAR-encoding DNA to T cells through electroporation, which uses brief electrical pulses to increase cell permeability. However, CAR expression was very short-lived, with limited antitumor effects, he said, and patients required multiple infusions to maintain even those transient CAR levels.. In this study, the ...
This phase I trial studies the side effects and best dose of modified immune cells (IL13Ralpha2 CAR T cells) after a chemotherapy conditioning regimen for the treatment of patients with stage IIIC or IV melanoma. The study agent is called IL13Ralpha2 CAR T cells. T cells are a special type of white blood cell (immune cells) that have the ability to kill tumor cells. The T cells are obtained from the patients own blood, grown in a laboratory, and modified by adding the IL13Ralpha2 CAR gene. The IL13Ralpha2 CAR gene is inserted into T cells with a virus called a lentivirus. The lentivirus allows cells to make the IL13Ralpha2 CAR protein. This CAR has been designed to bind to a protein on the surface of tumor cells called IL13Ralpha2. This study is being done to determine the dose at which the gene-modified immune cells are safe, how long the cells stay in the body, and if the cells are able to attack the cancer ...
The observation of strong CAR downregulation at the mRNA level at high cardiomyocyte densities suggests cell-to-cell contact-dependent signaling as one possible regulatory mechanism of CAR gene transcription. Indeed, the cellular targeting of recombinant CAR in cardiomyocytes and the CAR expression patterns in human DCM5 indicate that CAR does fulfill one important requirement for molecules involved in cell-to-cell contact-dependent signaling: ie, aggregation at sites of cell-to-cell contacts.21 In addition, the medium transfer experiments summarized in Figure 5 indicate that the regulation does not occur via diffusible intermediates. Cell-to-cell contact-dependent signals (in contrast to paracrine signals requiring diffusible intermediates such as norepinephrine, ET-1, angiotensin-II, CT-1, LIF, tumor necrosis factor-α, interleukin-6) have been shown to play a key role in fine patterning during embryogenesis, whereas paracrine signaling allows patterning of large embryonic fields.21 Among the ...
Look at any Houston newspaper from the 1950s and youll find some write-up on a car wreck. Doesnt even have to be a deadly crash. If two cars (or a truck, van, whatever) collided, it made the news. That kinda continued for the next 20 years or so, especially as getting around Houston became more of a challenge. These days, a wreck has to be pretty spectacular, or responsible for major delays, to merit attention in the paper or on As youd expect, we have plenty of photos from said wrecks. Some looked minor while others were pretty serious. (The bus photo, however, is quite the head-scratcher.) Ill say this, Id much rather be in a car wreck in a late-model car than these older cars. However, if anyone out there wants to sell me their old Lincoln Town Car, drop me a line. One thing to keep in mind is that no one died in any of the wrecks shown here. How do I know that? We have a separate file for fatal accidents. ...

8/20/2015 Related Story: Vehicles Damaged By Highway 169 Expansion Joint. Leslie Porter was on her way to work when she noticed a few other cars off the roadway changing tires.. She says she thought there had been an accident, not realizing she was headed straight for the problem.. I was doing 60, getting ready to come off the freeway and thats when it happened, and you know I heard this big old thump, thump and you know like when you run over something and it hits the bottom of your car? Thats what I thought it was.. A metal expansion joint went right into both her drivers side tires, causing two flats in seconds.. She says by the time she realized what happened, she saw other cars behind her do the same thing.. Eleven vehicles and one 18 wheeler all hit the exposed joint, puncturing tires, oil pans and other damage.. We dispatched crews and during that few minutes we started realizing that it was a much bigger issue than just a few rocks that were on the highway, ODOTs Martin Stewart ...
A novel CAR-based approach targeting HIV infection using the genetic modification of stem cells shows promise in preclinical models.
Figure 2b of the paper showing the surface of the fibre knob (HAd3K) involved in receptor binding. The amino acids involved in binding are highlighted in dark purple and light purple.. The results show that the adenovirus knob proteins differ from other related viruses in the ratio of binding sites between the fibre knob and the receptor, as well as in the binding surfaces themselves. To investigate the binding properties further, the researchers looked for mutations that prevented the virus from entering cells. Proteins, such as the adenovirus fibre knob, consist of a string of amino acid molecules, which fold into a 3D structure that is crucial for binding interactions. Remarkably, it was found that if a mutation causes the amino acid Asp261 to change, then the adenovirus cannot bind to the human cell ...

Police in a British city said they are considering new driving rules after an officer totaled an unmarked car during a test drive.
Engineered T cells using CARs or TCRs have the potential for serious side effects, both on-target/on-tumor (CRS), and on target/off tumor (HER2 CAR lung tox), in addition to straight off-target (Titin cross-reactive MAGE-A3 TCR). There are numerous safety switch technologies different groups have developed to either remove the engineered T cells or, more recently, control CAR expression/function. The safety switch designs currently being used in the clinic generally rely on inducible removal of the engineered T cells, such as Bellicums inducible caspase 9 approach, and Junos truncated EGFR, although the latter has never been used as a safety switch in the clinic. In UPenns abstract here, they wanted to design a CAR that could be inducibly down-regulated, to avoid irreversibly ablating the engineered T cells, which occurs with the previously mentioned strategies. UPenns approach is to attach an inducible degradation component to the CAR construct. I believe the one they are using is this LID ...

Im not an expert on the details, but Im guessing that is a legacy finance issue. No reason why a contract couldnt be designed that treated the first week and the rest of the finance term differently, where the buyer agreed to both, and the return was greatly streamlined.. I think the biggest issue with a typical car loan is that the market value of the car decreases after its driven off the lot, so Tesla must have some plan for dealing with that aspect of the first week returns. My guess is that they are declaring a vehicle new if it has under 500 miles on it, and they include the distance the car may be driven for delivery in that 500 mile new buffer. Thus if you take the car on a weekend getaway and return it with under 500 miles on it, it is still new (by definition) or at least as new as the Tesla that was driven 450 miles from a distribution center to a customers door.. Normal dealers sell vehicles all the time that have been demos for sales people and may have a few hundred ...
Nissan announced Wednesday their research for enabling vehicles to interpret signals from the drivers brain, consequently introducing a whole new chapter in human-to-car interaction.
The nature of the specificity of Ad12 knob for CAR is suggested by the structure of the complex, particularly at the interface that is formed by four loop regions of Ad12 knob interacting with a single face of the CAR D1 sandwich. Specifically, the AB loop, the carboxyl ends of the DE loop, and the very short F strand of one knob monomer and the FG loop of the adjacent knob monomer interact with strands C, C′, C, and the second half of strand F in CAR D1. The AB loop (colored yellow in Fig. 1A) contributes over 50% of interfacial protein-protein interactions, including the three hydrogen bonds involving conserved atoms in Ad12 knob [D415 O on knob forms a hydrogen bond with K104 Nζ on CAR D1 (D415 O/K104 Nζ), L426 O/Y64 OH, and K429 Nζ/E37 Oɛ2] (10), and thus may be the key anchor for the complex. This loop spans the width of the CAR D1, held at one end by D415 and at the other end by E425, which changes rotomer conformation upon CAR D1 binding to accommodate the approaching side chain of ...
Cars that are capable of driving themselves could become a reality within a decade, thanks to a new EU-sponsored project. The plan is to create cars that are capable of driving themselves in convoys under the control of a driver in a lead vehicle. Cars in the convoy would travel with small gaps between them, cutting both fuel consumption and CO2 emissions by up to 20%. When a car approaches its chosen exit, the driver will retake control and move out of the convoy, with other vehicles then moving up to close the gap. Both Volvo and British-based engineering consultancy Ricardo are partners in the project, dubbed SARTRE (SAfe Road TRains for the Environment), which aims to dramatically reduce CO2 emissions. First test cars on track for 2011 ...
I hope you have found a hand control for your car by now. Since you live near a big city, there will be many providers of hand controls in your area. This is a routine and simple job for them and the hand controls and installation are not very expensive. I believe mine was less than $1000 installed. They are easy to use but you do need to concentrate for a while so you dont make mistakes. The nice thing is that the car can still be driven normally by a person without a handicap so when necessary anyone can drive the car. I seem to recall that medicare doesnt cover modifications to cars, at least I paid for mine myself. When your legs are not totally responsive, it is imperative that you get hand controls before you find yourself in an accident that may injure you or someone else unnecessarily. They do disconnect the steering wheel tilt so that it is in a fixed position. I believe you can specifiy the position you want if there is room for you to operate the vehicle, get in etc. I have had mine ...
Saturday morning, I took my car to the dealership, because the stupid check engine light was on. I purposely took it early - 8:00 a.m., so that I would have it back, hopefully by noon. The guy at the counter asked that I leave my number, and wait at home for it, because there were 4 people in front of me. I dont usually have a problem doing this, because (A) I live about a 10-minute walk from the place, and (B) I usually dont need the car on Saturday. However, I know that when I leave the car there, it immediately drops on the priority chart at the dealership. I called the place at around 12:30 p.m., because I heard nothing from them. Shockingly enough, they were just getting to my car at this point. I informed the guy that I expressly dropped my car off in the morning, so that I could get it back sooner. I called back at 2:00 - the car still wasnt done. I immediately sent an e-mail to the dealership informing them of my complete disgust in them. I did finally get the car at 2:30 p.m. - ...
The writer claims to have made excessive commissions by selling customers options they didnt need. This type of selling is highly unethical and it undermines the fair business practices that our industry strives so hard to uphold.. For this man to have made $17,000 in three months (as he claims), he would have had to sell an average of 19 cars a month. This strains credibility, particularly since most experienced salespeople average about 10 cars per month.. The author also provided tips for new car shoppers (in bold). My observations on his comments follow.. 1. Do your homework. Absolutely. Salespeople prefer to deal with educated and well-informed customers. It makes their jobs easier and provides for a more efficient sales process.. 2. Find the biggest dealership. Larger volume dealerships dont offer better deals; all dealers pay the same price for new vehicles from the manufacturers. My advice would be to do business with a dealer closest to your home or work, so that you can develop a ...

  • Unexpectedly, this factor was identified as protein VI, a 22-kDa cement protein located beneath the peripentonal hexons in the viral capsid. (
  • A new model of Ad entry is proposed based on our present observations of capsid disassembly and membrane penetration. (
  • First, the capsids of nonenveloped virions are assembled as immature stable structures that are rendered metastable upon proteolytic processing of capsid proteins ( 17 ). (
  • Conformational changes often expose hydrophobic residues that subsequently interact with and reorganize the membrane bilayer, enabling cytosolic translocation of the viral genome, transcription complex, or partially disassembled virus capsid. (
  • Other so-called minor capsid components, including proteins IIIa, VI, VIII, and IX, are thought to act primarily as cement proteins that help to stabilize the viral particle. (
  • While the location in the capsid and precise role in the Ad life cycle of these capsid components have yet to be fully elucidated, protein VI was recently shown to act as a shuttling adaptor for hexon import into the nucleus ( 53 ). (
  • Internalization of Ad is thought to trigger capsid disassembly, starting with the loss of the fiber protein at the cell surface ( 26 ). (
  • Acid-induced conformational changes in the capsid are thought to be required for membrane penetration, allowing cytosolic translocation of the partially uncoated virion containing the DNA, core proteins, hexon, and protein VIII ( 14 ). (
  • However, the precise relationship between Ad capsid disassembly and the development of membrane lytic activity has not been established. (
  • Further insights into the role of Ad capsid alterations in membrane penetration have been obtained by analyses of a temperature-sensitive mutant of Ad type 2 (Ad2), ts 1. (

  • Adenoviruses (Ad) are hybrids: They are nonenveloped but have trimeric fibers (320 to 587 residues) emanating from the vertices of their icosahedral capsid, which terminate in globular knob domains (∼175 residues). (
  • The genome also codes for 4 capsid proteins, VP4, VP1, VP2, and VP3 that form an icosahedral capsid for the viral particles that is about 30 nm. (
  • The capsid of Coxsackie viruses have a distinguishable depression around the fivefold axis, termed the "canyon. (
  • Uncoating is unnecessary as it leaves the capsid at the plasma membrane and the genome is simply injected into the cytoplasm. (
  • Viral capsid proteins come together to form pentamers, 12 of which come together to form an empty capsid, or procapsid (Expasy, Hunt, 2010). (
  • Here we have studied whether the rotavirus outer capsid proteins are capable of opening the paracellular space sealed by the TJ. (

  • Like other picornaviruses, CVB3 has a small, 30-nm-diameter nonenveloped capsid composed of structural proteins VP1 to VP4. (
  • The final stages of entry have been studied by several low-resolution asymmetric structures formed on liposomes ( 14 - 17 ) and by higher-resolution icosahedrally averaged A-particles made by applying global capsid stimulation, such as heat or excess soluble receptor molecules ( 11 , 13 , 18 - 20 ). (
  • These and other structures suggest a model of entry whereby binding of receptor initiates conformational changes beginning with loss of pocket factor, followed by an irreversible capsid expansion ( 20 ). (
  • The internal VP1 N termini subsequently extrude through the capsid shell at the quasi-threefold axis, at a raised region termed the "propeller tip," and embed into the endosome membrane, anchoring the A-particle by forming an amphipathic helix ( 11 , 18 , 21 - 23 ). (

  • Researchers indicated that coxsackie and adenovirus receptor (CAR)-SIV was the principal isoform in islets and was localized mainly within the cytoplasm of beta cells, rather than at the plasma membrane. (
  • Early experiments suggested that the expression of specific viral receptors on susceptible cells was a major determinant of enterovirus host range and tissue tropism ( 12 , 17 ), and the particular susceptibility of newborn mice to encephalitis caused by coxsackie B viruses ( 9 , 10 ) was related to the abundant expression of receptors in the newborn-but not the adult-brain ( 18 , 19 ).

  • As soon as viral proteins have been translated and cleaved, negative sense transcripts of the viral genome are made to serve as a template for more positive-sense viral genome transcripts (which also serves as mRNA which can also be translated into more viral proteins). (

  • Adenoviruses possess the critical basic properties required for viral oncolysis ( 3 ). (
  • In this regard, successful viral spread relies on the capability of viral capsids to (i) shelter the viral genome, (ii) display molecular determinants for cell receptor recognition, (iii) facilitate efficient genome delivery, and (iv) escape from the immune system. (
  • Viral infections are initiated by attachment of the virus to host cell surface receptors, including sialic acid-containing glycans. (
  • CVB entry into cells is regulated at the viral receptor interface and is mediated by intracellular signal cascades (9, 12-14). (
  • Entry is dependent upon binding to Coxsackievirus Adenovirus Receptor (CAR), which assists in viral conformational change and endocytosis (15-18). (

  • Disrupting MAPK pathway signaling by pharmacological inhibition of MEK up-regulates CAR expression, offering possible enhanced adenovirus infection. (
  • Subsequent infection of host cells by newly assembled mature virions is initiated by the binding of the Ad fiber protein to the coxsackie B and Ad receptor (CAR) ( 4 ) or CD46 ( 12 , 27 , 34 , 41 , 54 ). (
  • To improve infection efficiency of primary glioma cells, which express low levels of coxsackie adenovirus receptor (CAR), the tropism of AdDelta24 was expanded toward alphav integrins by insertion of an Arg-Gly-Asp (RGD) motif into the fiber knob (Ad5-Delta24RGD). (
