Abstract
Global efforts are underway to eliminate measles and rubella, and active viral surveillance is the key to achieving this goal. In addition, the World Health Organization announced guidelines for handling materials potentially infectious for poliovirus (PV) to minimize the risk of PV reintroduction and to achieve PV eradication. To support global efforts, we established new PV-non-susceptible cell lines that are useful for the isolation of measles virus (MeV) and rubella virus (RuV) (Vero ΔPVR1/2 hSLAM+). In the cell lines, MeV and RuV replicated efficiently, with no concern regarding PV replication.

Abstract
Polio or poliomyelitis is a disabling and life-threatening disease caused by poliovirus (PV). As a consequence of global polio vaccination efforts, wild PV serotypes 2 and 3 have been eradicated around the world, and wild PV serotype 1-transmitted cases have been largely eliminated except for limited regions. However, vaccine-derived PV, pathogenically reverted live PV vaccine strains, has become a serious issue. For the global eradication of polio, the World Health Organization is conducting the third edition of the Global Action Plan, which is requesting stringent control of potentially PV-infected materials. To facilitate the mission, we generated a PV-nonsusceptible Vero cell subline, which may serve as an ideal replacement of standard Vero cells to isolate emerging/re-emerging viruses without the risk of generating PV-infected materials.

Abstract
BACKGROUND & OBJECTIVES It is important to understand the role of cell surface receptors in susceptibility to infectious diseases. CD155 a member of the immunoglobulin super family, serves as the poliovirus receptor (PVR). Heterozygous (Ala67Thr) polymorphism in CD155 has been suggested as a risk factor for paralytic outcome of poliovirus infection. The present study pertains to the development of a screening test to detect the single nucleotide (SNP) polymorphism in the CD155 gene. METHODS New primers were designed for PCR, sequencing and SNP analysis of Exon2 of CD155 gene. DNAs extracted from either whole blood (n=75) or cells from oral cavity (n=75) were used for standardization and validation of the SNP assay. DNA sequencing was used as the gold standard method. RESULTS A new SNP assay for detection of heterozygous Ala67Thr genotype was developed and validated by testing 150 DNA samples. Heterozygous CD155 was detected in 27.33 per cent (41/150) of DNA samples tested by both SNP detection assay and sequencing. INTERPRETATION & CONCLUSIONS The SNP detection assay was successfully developed for identification of Ala67Thr polymorphism in human PVR/CD155 gene. The SNP assay will be useful for large scale screening of DNA samples.

Abstract
RIG-I-like receptors and Toll-like receptors (TLRs) play important roles in the recognition of viral infections. However, how these molecules contribute to the defense against poliovirus (PV) infection remains unclear. We characterized the roles of these sensors in PV infection in transgenic mice expressing the PV receptor. We observed that alpha/beta interferon (IFN-α/β) production in response to PV infection occurred in an MDA5-dependent but RIG-I-independent manner in primary cultured kidney cells in vitro. These results suggest that, similar to the RNA of other picornaviruses, PV RNA is recognized by MDA5. However, serum IFN-α levels, the viral load in nonneural tissues, and mortality rates did not differ significantly between MDA5-deficient mice and wild-type mice. In contrast, we observed that serum IFN production was abrogated and that the viral load in nonneural tissues and mortality rates were both markedly higher in TIR domain-containing adaptor-inducing IFN-β (TRIF)-deficient and TLR3-deficient mice than in wild-type mice. The mortality rate of MyD88-deficient mice was slightly higher than that of wild-type mice. These results suggest that multiple pathways are involved in the antiviral response in mice and that the TLR3-TRIF-mediated signaling pathway plays an essential role in the antiviral response against PV infection.

Abstract
In contrast to Old World monkeys, most New World monkeys (NWMs) are not susceptible to poliovirus (PV), regardless of the route of infection. We have investigated the molecular basis of restricted PV pathogenesis of NWMs with two kidney cell lines of NWMs, TMX (tamarin) and NZP-60 (marmoset), and characterized their PV receptor homologues. TMX cells were susceptible to infection by PV1 (Mahoney) and PV3 (Leon) but not by PV2 (Lansing). Binding studies to TMX cells indicated that the formation of PV/receptor complexes increased when measured first at 4 degrees C and then at 25 degrees C, whereas PV2 did not significantly bind to TMX cells at either temperature. On the other hand, NZP-60 cells were not susceptible to infection by any of the PV serotypes. However, a low amount of PV1 bound to NZP-60 cells at 4 degrees C, but there was no increase of binding at 25 degrees C. In contrast, both NWM cell lines supported genome replication and virion formation when transfected with viral RNAs of either serotype, an observation indicating that infection was blocked in receptor-virus interaction. To overcome the receptor block, we substituted 3 amino acids in the marmoset receptor (nCD155), H80Q, N85S, and P87S, found in the human PV receptor, hCD155. Cells expressing the mutant receptor (L-nCD155mt) were now susceptible to infection with PV1, which correlated with an increase in PV1-bound receptor complexes from 4 degrees C to 25 degrees C. L-nCD155mt cells were, however, still resistant to PV2 and PV3. These data show that an increase in the formation of PV/receptor complexes, when measured at 4 degrees C and at 25 degrees C, correlates with and is an indicator of successful infection at 37 degrees C, suggesting that the complex formed at 25 degrees C may be an intermediate in PV uptake.

Abstract
Poliovirus (PV)-induced apoptosis seems to play a major role in tissue injury in the central nervous system (CNS). We have previously shown that this process involves PV-induced Bax-dependent mitochondrial dysfunction mediated by early JNK activation in IMR5 neuroblastoma cells. We showed here that PV simultaneously activates the phosphatidylinositol 3-kinase (PI3K)/Akt survival signaling pathway in these cells, limiting the extent of JNK activation and thereby cell death. JNK inhibition is associated with PI3K-dependent negative regulation of the apoptosis signal-regulating kinase 1, which acts upstream from JNK in PV-infected IMR5 cells. In poliomyelitis, this survival pathway may limit the spread of PV-induced damage in the CNS.

Abstract
Poliovirus (PV) is the causal agent of paralytic poliomyelitis, a disease that involves the destruction of motor neurons associated with PV replication. In PV-infected mice, motor neurons die through an apoptotic process. However, mechanisms by which PV induces cell death in neuronal cells remain unclear. Here, we demonstrate that PV infection of neuronal IMR5 cells induces cytochrome c release from mitochondria and loss of mitochondrial transmembrane potential, both of which are evidence of mitochondrial outer membrane permeabilization. PV infection also activates Bax, a proapoptotic member of the Bcl-2 family; this activation involves its conformational change and its redistribution from the cytosol to mitochondria. Neutralization of Bax by vMIA protein expression prevents cytochrome c release, consistent with a contribution of PV-induced Bax activation to mitochondrial outer membrane permeabilization. Interestingly, we also found that c-Jun NH(2)-terminal kinase (JNK) is activated soon after PV infection and that the PV-cell receptor interaction alone is sufficient to induce JNK activation. Moreover, the pharmacological inhibition of JNK by SP600125 inhibits Bax activation and cytochrome c release. This is, to our knowledge, the first demonstration of JNK-mediated Bax-dependent apoptosis in PV-infected cells. Our findings contribute to our understanding of poliomyelitis pathogenesis at the cellular level.

Abstract
The three poliovirus serotypes (PVs) cause acute paralytic poliomyelitis. Decades after being hit by polio, survivors may develop a condition known as post-polio syndrome (PPS). PPS is characterized by extreme fatigue, progressing muscular weakness and chronic pain. The pathogenesis is unclear and, thus, empirical therapies are employed. PVs are known to be able to persist in infected host cells both in vitro and in vivo. The understanding of PV genomes has made it possible to set up sensitive and specific molecular tests capable of detecting minute amounts of virus in samples from PPS patients. Current data indicate that complete PV genomes (or genomic fragments) remain present, decades after acute paralysis, in the CNS of these patients. Virus persistence is hypothesized to bring about chronic inflammation, immune-mediated injury and decreased expression of neurotrophic factors. Establishing a pathogenetic link between PV persistence and PPS would be extremely relevant to the development of an etiologic therapy aimed at virus eradication.

Abstract
Replication of poliovirus (PV) is restricted to a few sites, including the brain and spinal cord. However, this neurotropism is not conserved in cultured cells. Monkey kidney cells become susceptible to PV infection after cultivation in vitro, and cell lines of monolayer cultures from almost any tissue of primates are susceptible to PV infection. These observations suggest that cellular changes during cultivation are required for acquisition of susceptibility. The molecular basis for the cellular changes during this process is not known. We investigated the relationship between PV susceptibility and interferon (IFN) response in primary cultured kidney and liver cells derived from transgenic mice expressing human PV receptor and in several primate cell lines. Both kidneys and liver in vivo showed rapid IFN response within 6 h postinfection. However, monkey and mouse kidney cells in culture and primate cell lines, which were susceptible to PV, did not show such rapid response or showed no response at all. On the other hand, primary cultured liver cells, which were partially resistant to infection, showed rapid IFN induction. The loss of IFN inducibility in kidney cells was associated with a decrease in expression of IFN-stimulated genes involved in IFN response. Mouse kidney cells pretreated with a small dose of IFN, in turn, restored IFN inducibility and resistance to PV. These results strongly suggest that the cells in culture acquire PV susceptibility during the process of cultivation by losing rapid IFN response that has been normally maintained in extraneural tissues in vivo.

Abstract
Poliovirus is the etiological agent of poliomyelitis. From the observations that only simians are susceptible to poliovirus infection and that 37 amino acid sites (the poliovirus-binding associated [PBA] sites) in the domain D1 of CD155 are involved in the binding to poliovirus, it is considered that the susceptibility to poliovirus infection evolved through amino acid substitutions that occurred at the PBA sites on the ancestral branch of simians. Here it is shown that positive selection has operated on these substitutions by analyzing the nucleotide sequences encoding almost the entire region of D1 in humans, non-human hominoids (chimpanzees and gorillas), Old World monkeys (African green monkeys), New World monkeys (brown capuchins, squirrel monkeys, and marmosets), prosimians (ring-tailed lemurs), and non-primate mammals (rabbits). Positive selection is unlikely to have operated on the susceptibility to poliovirus infection, but possibly on the binding to another molecule. Elimination of susceptibility to poliovirus infection in simians may be difficult, because it also requires elimination of advantageous effects that have been exerted by CD155.

Abstract
Poliovirus selectively replicates in neurons in the spinal cord and brainstem, although poliovirus receptor (PVR) expression is observed in both the target and nontarget tissues in humans and transgenic mice expressing human PVR (PVR-transgenic mice). We assessed the role of alpha/beta interferon (IFN) in determining tissue tropism by comparing the pathogenesis of the virulent Mahoney strain in PVR-transgenic mice and PVR-transgenic mice deficient in the alpha/beta IFN receptor gene (PVR-transgenic/Ifnar knockout mice). PVR-transgenic/Ifnar knockout mice showed increased susceptibility to poliovirus. After intravenous inoculation, severe lesions positive for the poliovirus antigen were detected in the liver, spleen, and pancreas in addition to the central nervous system. These results suggest that the alpha/beta IFN system plays an important role in determining tissue tropism by protecting nontarget tissues that are potentially susceptible to infection. We subsequently examined the expression of IFN and IFN-stimulated genes (ISGs) in the PVR-transgenic mice. In the nontarget tissues, ISGs were expressed even in the noninfected state, and the expression level increased soon after poliovirus infection. On the contrary, in the target tissues, ISG expression was low in the noninfected state and sufficient response after poliovirus infection was not observed. The results suggest that the unequal IFN response is one of the important determinants for the differential susceptibility of tissues to poliovirus. We consider that poliovirus replication was observed in the nontarget tissues of PVR-transgenic/Ifnar knockout mice because the IFN response was null in all tissues.

Abstract
PURPOSE Spread to the central nervous system (CNS) and the leptomeninges is a frequent complication of systemic cancers that is associated with serious morbidity and high mortality. We have evaluated a novel therapeutic approach against CNS complications of breast cancer based on the human neuropathogen poliovirus (PV). EXPERIMENTAL DESIGN Susceptibility to PV infection and ensuing rapid cell lysis is mediated by the cellular receptor of PV, CD155. We evaluated CD155 expression in several human breast tumor tissue specimens and cultured breast cancer cell lines. In addition, we tested an oncolytic PV recombinant for efficacy in xenotransplantation models of neoplastic meningitis and cerebral metastasis secondary to breast cancer. RESULTS We observed that breast cancer tissues and cell lines derived thereof express CD155 at levels mediating exquisite sensitivity toward PV-induced oncolysis in the latter. An association with the immunoglobulin superfamily molecule CD155 renders breast cancer a likely target for oncolytic PV recombinants. This assumption was confirmed in xenotransplantation models for neoplastic meningitis or solitary cerebral metastasis, where local virus treatment dramatically improved survival. CONCLUSIONS Our findings suggest oncolytic PV recombinants as a viable treatment option for CNS complications of breast cancer.

Abstract
Poliovirus (PV) is the causal agent of paralytic poliomyelitis, an acute disease of the central nervous system (CNS) resulting in flaccid paralysis. The development of new animal and cell models has allowed the key steps of the pathogenesis of poliomyelitis to be investigated at the molecular level. In particular, it has been shown that PV-induced apoptosis is an important component of the tissue injury in the CNS of infected mice, which leads to paralysis. In this review the molecular biology of PV and the pathogenesis of poliomyelitis are briefly described, and then several models of PV-induced apoptosis are considered; the role of the cellular receptor of PV, CD155, in the modulation of apoptosis is also addressed.

Abstract
CD155 (poliovirus receptor) localizes in cell-matrix adhesions and cell-cell junctions, but its role in the regulation of cell adhesion and cell motility has not been investigated. We identified a conserved immunoreceptor tyrosine-based inhibitory motif (ITIM) in the cytoplasmic domain of human CD155alpha. The ITIM was tyrosine-phosphorylated upon binding of anti-CD155 monoclonal antibody D171, poliovirus, and DNAM-1 (CD226) to human CD155alpha, and recruited SH2-domain-containing tyrosine phosphatase-2 (SHP-2). After CD155alpha stimulation with its ligands, cell adhesion was inhibited and cell motility was enhanced, effects that were associated with the phosphorylation of ITIM by Src kinases and accompanied by dephosphorylation of focal adhesion kinase and paxillin. These effects were abolished by introducing a point-mutation in Y398F into the ITIM of CD155alpha and by coexpression of a dominant negative SHP-2 mutant with CD155alpha. These results suggest that CD155alpha plays a role in the regulation of cell adhesion and cell motility.

Abstract
CD155 is a member of the immunoglobulin superfamily also known as the human receptor for poliovirus (PVR). Transmembrane glycoproteins related to CD155, the nectins, are well-characterized cell adhesion receptors displaying a high degree of sequence conservation across species. In contrast, CD155 belongs to the category of rapidly evolving genes wherefore a mouse CD155 gene distinguished by an affirmative extent of amino acid conservation as observed for nectins is absent. Consequently, the existing genetic evidence by itself is an inferior indicator to consider whether Tage4, a mouse orphan receptor, represents the murine orthologue of CD155. In the present study Tage4 cDNA was cloned from mouse lung and further characterized genetically. CD155 and Tage4 possess an identical genomic organization and reside in syntenic chromosomal regions. The Tage4 expression pattern was explored applying a newly generated antibody. Both receptors, CD155 in human and Tage4 in mouse, are expressed by intestinal epithelia as well as by follicle associated epithelium and follicular dendritic cells inside Peyer's patches of the gut associated lymphoid tissue. Furthermore, Tage4 lacks self-adhesion capacity but binds to vitronectin, two known features of CD155. These data indicate that Tage4 represents the functional orthologue of CD155 in mouse. Therefore, we suggest to rename Tage4 into rodent CD155.

Abstract
The CD155 gene is a member of the immunoglobulin superfamily. We first demonstrate the existence of soluble CD155 (sCD155) isoforms in culture medium conditioned by CD155-expressing cells, in human serum and in cerebrospinal fluid. sCD155 concentration was measured in human serum and cerebrospinal fluid using a specific ELISA. Analysis of conditioned media indicated that sCD155 release does not require protease activity. In order to determine which tissues are responsible for sCD155 expression, we have quantified CD155 mRNAs in human normal tissues. The highest expression was observed in liver. The CD155alpha transcript is the most abundant and the proportion of the CD155beta and CD155gamma variants was similar between the tissues. Finally, serum purified sCD155 reduces poliovirus entry mediated by membrane-bound CD155. The high level of CD155 synthesis in many tissues and the presence of sCD155 in biological fluids suggest the existence of an important role for the protein in cellular function.

Abstract
Malignant transformation of cells causes disruption of cell-cell adhesion, enhancement of cell motility, and invasion into surrounding tissues. Nectins have both homophilic and heterophilic cell-cell adhesion activities and organize adherens junctions in cooperation with cadherins. We examined here whether Tage4, which was originally identified to be a gene overexpressed in colon carcinoma and has a domain structure similar to those of nectins, is involved in cell adhesion and/or migration. Tage4 heterophilically trans-interacted with nectin-3, but not homophilically with Tage4. Expression of Tage4 was markedly elevated in NIH3T3 cells transformed by an oncogenic Ki-Ras (V12Ras-NIH3T3 cells) as compared with that of wild-type NIH3T3 cells. trans-Interaction of Tage4 with nectin-3 enhanced motility of V12Ras-NIH3T3 cells. Tage4 did not bind afadin, a nectin- and actin filament-binding protein that connects nectins to the actin cytoskeleton and cadherins through catenins. Thus, Tage4 heterophilically trans-interacts with nectin-3 and regulates cell migration. Tage4 is tentatively re-named here nectin-like molecule-5 (necl-5) on the basis of its function and domain structure similar to those of nectins.

Abstract
In order to determine the influence of poliovirus receptor (PVR) expression on poliovirus cell tropism and neuropathogenesis, two transgenic (tg) mouse models were produced in which PVR was expressed under the transcriptional control of the human PVR gene promoter (hg-PVR mice) and the CAG promoter (CAG-PVR mice). Then the pathogenicity of poliovirus after intracerebral inoculation of the type 1 Mahoney strain was compared. These showed completely different clinical and pathological changes. In the former, the expression of PVR in neurons in the central nervous system (CNS) conferred susceptibility to poliovirus, and a paralytic disease that resembled the human poliomyelitis occurred. In the latter, PVR expression was detected in glial and ependymal cells in addition to the neurons. Paralysis of the limbs and death were rarely observed and mice survived without showing substantial clinical abnormality. Histopathological examination revealed that glial and ependymal cells also became susceptible to poliovirus infection. Poliovirus antigens were mainly detected in ependymal and glial cells and hippocampal neurons near the lateral ventricles in the brain, but were not frequently detected in neurons in the brainstem unlike in the hg-PVR mice. The levels of viral antigens and virus recovered from the CNS of CAG-PVR mice began to decrease as early as 2 days after inoculation, which suggested induction of a fast immune response. These results suggest that the neuropathogenicity of poliovirus changes markedly depending on the specific expression of the PVR molecule in the CNS.

Abstract
Poliovirus receptor (hPVR/CD155) is a cell surface glycoprotein that belongs to the immunoglobulin superfamily but its natural function remains unknown. Two membrane-bound isoforms, hPVRalpha and hPVRdelta, are known to date, and they differ only in the amino acid sequence of their cytoplasmic domains. To gain an insight into the possible function of the cytoplasmic domains, we examined the localization of introduced hPVRalpha and hPVRdelta in polarized epithelial cells deficient of native hPVRs. Basolateral sorting of hPVRalpha was observed in Madine-Darby canine kidney cells expressing mu1B, but not in LLC-PK1 porcine kidney cells deficient in mu1B. Distribution of hPVRdelta, however, occurred both on the apical and basolateral plasma membranes of these two cell lines. Basolateral sorting of hPVRalpha was also seen in LLC-PK1 cells that expressed an intact exogenous mu1B, but not in the cells that expressed a mutant mu1B lacking binding ability to tyrosine-containing signals. These results indicate that mu1B is involved in the distribution of hPVRalpha to the basolateral membrane. Comparative distribution analysis of hPVRalpha using a series of mutants with truncations and substitutions in the cytoplasmic tail demonstrated that determinant for the basolateral sorting resided in the tyrosine-containing motif of the cytoplasmic tail. Furthermore, yeast two hybrid analysis strongly suggested that the tyrosine motif directly interacted with mu1B protein. Thus, basolateral sorting of hPVRalpha appears to involve the interaction with mu1B through a tyrosine motif existing in the cytoplasmic domain.

Abstract
The human receptor for poliovirus (CD155) is an immunoglobulin-like molecule with unknown normal function(s). Here we provide evidence that CD155 binds specifically to vitronectin with a dissociation constant (K(d)) of 72 nM as determined by surface plasmon resonance. Based on sequence homology to the CD155 gene, three poliovirus receptor-related genes (PRR1, PRR2, and PRR3) were cloned recently. PRR proteins were reported by others to mediate homophilic cell adhesion. Neither PRR1 nor PRR2 binds poliovirus and it is assumed that their physiological functions differ from that of CD155. Indeed, mPRR2 was found to bind to vitronectin only weakly, while its self-adhesion activity is characterized by a K(d) of 310 nM. Moreover, there is no evidence for CD155 self-adhesion. Both CD155 and vitronectin colocalize to follicular dendritic cells and B cells inside the germinal centers of secondary lymphoid tissue (tonsils)-an observation suggesting that the CD155/vitronectin interaction is required for the establishment of a proper immune response in this particular context.

Abstract
The gene for the human poliovirus receptor (hPVR/CD155) is the founding member of a new family of genes encoding proteins belonging to the immunoglobulin superfamily. To determine whether CD155 is expressed during mammalian development, we have made use of the previously characterized promoter of the CD155 gene and generated mice transgenic for a CD155 promoter-driven beta-galactosidase reporter gene. Expression of the reporter gene in transgenic embryos was observed during midgestation in anterior midline structures of the developing central nervous system and in the neuroretina. During that period, reporter gene expression appeared within the notochord and floor plate along the entire spinal cord reaching into the caudal diencephalon. In addition, transgene expression was observed in axonal projections emanating from retinal ganglion cells forming the optic nerve to reach the future region of the optic chiasm. Analysis of expression of CD155 during human embryonic development confirmed the distribution of reporter gene expression specified by CD155 promoter activity. The anatomical distribution of CD155 promoter activity during embryogenesis matches that of transacting factors previously identified to regulate transcription of the CD155 gene. Expression of CD155 within embryonic structures giving rise to spinal cord anterior horn motor neurons may explain the restrictive host cell tropism of poliovirus for this cellular compartment of the CNS.

Abstract
The ability of a virus to attach to a susceptible host cell is of utmost importance for the initiation of viral life cycle. Cell surface proteins called viral receptors mediate the initial steps of virus attachment and uptake. Poliovirus (PV) is one of the most studied animal viruses and its interaction with its cellular receptor, the human poliovirus receptor (hPVR) has been well characterized. This review will present our current understanding of the PV/hPVR interaction at the genetic and biochemical level. In addition, we will also discuss the implications of the PV/hPVR interaction on PV tissue tropism and the evolution of the three PV serotypes.

Abstract
In this report we describe a cis-acting element within the core promoter of the CD155 gene specifying the polio virus receptor that is bound by the nuclear respiratory factor-1 (NRF-1) transcription factor. DNase I footprint analysis identified a nuclear protein binding site from -282 to -264 nucleotides upstream of the translation initiation codon of the CD155 gene, which we have called foot print IV (FPIV). Linker scanning mutagenesis revealed that a tandem repeat motif, GCGCAGGCGCAG, located within FPIV was essential for the basal activity of the CD155 core promoter. The results of the electrophoretic mobility shift assay experiments suggested that identical FPIV binding activities were present in a variety of nuclear extracts and that the tandem repeat was essential for binding. A one-hybrid screen was then carried out using FPIV as bait to clone the cDNA of the FPIV binding factor. The sequences of the cDNAs that were cloned from the screen were identical to NRF-1, a result that was confirmed by further electrophoretic mobility shift assay experiments. Overexpression of full-length NRF-1 and a dominant-negative form of NRF-1 modulated reporter gene expression driven by the core promoter. Remarkably, CD155 is the first gene shown to be regulated by NRF-1 that possesses an expression profile during embryogenesis correlating with this factor's proposed role in the development of the vertebrate optic system. We propose that NRF-1, which has been shown by others to be expressed during embryogenesis in animal systems, may be involved in regulating the expression of CD155 at specific stages of central nervous system development.

Abstract
Nectin-2 is a cell adhesion molecule encoded by a member of the poliovirus receptor gene family. This family consists of human, monkey, rat, and murine genes that are members of the immunoglobulin gene superfamily. Nectin-2 is a component of cell-cell adherens junctions and interacts with l-afadin, an F-actin-binding protein. Disruption of both alleles of the murine nectin-2 gene resulted in morphologically aberrant spermatozoa with defects in nuclear and cytoskeletal morphology and mitochondrial localization. Homozygous null males are sterile, while homozygous null females, as well as heterozygous males and females, are fertile. The production by nectin-2(-/-) mice of normal numbers of spermatozoa containing wild-type levels of DNA suggests that Nectin-2 functions at a late stage of germ cell development. Consistent with such a role, Nectin-2 is expressed in the testes only during the later stages of spermatogenesis. The structural defects observed in spermatozoa of nectin-2(-/-) mice suggest a role for this protein in organization and reorganization of the cytoskeleton during spermiogenesis.

Abstract
Mice transgenic with the human poliovirus receptor gene develop clinical signs and neuropathology similar to those of human poliomyelitis when neurovirulent polioviruses are inoculated into the central nervous system (CNS). Factors contributing to disease severity and the frequencies of paralysis and mortality include the poliovirus strain, dose, and gender of the mouse inoculated. The more neurovirulent the virus, as defined by monkey challenge results, the higher the rate of paralysis, mortality, and severity of disease. Also, the time to disease onset is shorter for more neurovirulent viruses. Male mice are more susceptible to polioviruses than females. TGM-PRG-3 mice have a 10-fold higher transgene copy number and produce 3-fold more receptor RNA and protein levels in the CNS than TGM-PRG-1 mice. CNS inoculations with type III polioviruses differing in relative neurovirulence show that these mouse lines are similar in disease frequency and severity, demonstrating that differences in receptor gene dosage and concomitant receptor abundance do not affect susceptibility to infection. However, there is a difference in the rate of accumulation of clinical signs. The time to onset of disease is shorter for TGM-PRG-3 than TGM-PRG-1 mice. Thus, receptor dosage affects the rate of appearance of poliomyelitis in these mice.

Abstract
The CD155 protein is the founding member of a new group of related molecules within the immunoglobulin superfamily sharing a V-C2-C2 domain structure and significant amino acid identity. We have recently isolated the promoter of the CD155 gene so that we may determine the transcription factors that regulate its expression and possibly gain insight into the cell biology of this gene. Here we report the mapping of three cis-elements within the CD155 core promoter, designated FPI, II, and III. The results of linker scanning mutagenesis suggest that all three of these cis-elements are required in varying degrees for the promoter activity of the core promoter fragment. The relative contribution of each region ranked in the following order: III > II > I. Interestingly, footprint and electrophoretic mobility shift assays show that FPIII binding activity is much reduced in a human cell line that does not express CD155. Additionally, protein binding to FPI and FPII was also investigated. DNase I footprinting using recombinant hAP-2alpha indicated that this transcription factor bound to both the FPI and FPII regions of the CD155 core promoter fragment. Electrophoretic mobility shift assays and supershift analysis confirmed the binding of AP-2 from crude nuclear extracts to FPI and to FPII. Lastly, cotransfection of the CD155 promoter with an AP-2alpha expression vector indicates that overexpression of AP-2alpha modulated the promoter activity of a CD155 promoter construct.

Abstract
AbstractWe have recently described Poliovirus Receptor Related 2 (PRR2), a new cell surface molecule homologous to the poliovirus receptor (PVR/CD155). Both molecules are transmembrane glycoproteins belonging to the Ig superfamily (IgSF). They contain 3 Ig domains of V, C2, and C2 types in their extracellular regions that share 51% aa identity. The PRR2 gene encodes two mRNA isoforms of 3.0 kb (hPRR2 [short form]) and 4.4 kb (hPRR2δ [long form]), both widely expressed in human tissues, including hematopoietic cells. To further characterize PRR2 expression during hematopoiesis and to analyze its function, we have developed a monoclonal antibody (MoAb) directed against its extracellular region (R2.477). PRR2 was expressed in 96% of the CD34+, 88% of the CD33+, and 95% of the CD14+ hematopoietic lineages and faintly in the CD41 compartment. Ectopic expression of both PRR2 cDNAs induced marked cell aggregation. A soluble chimeric receptor construct with the Fc fragment of human IgG1 (PRR2-Fc) as well as a fab fragment of the anti-PRR2 MoAb (R2.477) inhibit aggregation. PRR2-Fc binds specifically to PRR2-expressing cells. These results suggest that PRR2 is a homophilic adhesion receptor. PRR2 was also expressed at the surface of endothelial cells at the intercellular junctions of adjacent cells but not at the free cellular edges. Homophilic interactions are associated with dimerization of isoforms of PRR2 and lead to the tyrosine phosphorylation of PRR2δ. Altogether, these results suggest that homophilic properties of PRR2 could participate to the regulation of hematopoietic/endothelial cell functions.

PRR2-Fc binds specifically to PRR2-expressing cells. These results suggest that PRR2 is a homophilic adhesion receptor. PRR2 was also expressed at the surface of endothelial cells at the intercellular junctions of adjacent cells but not at the free cellular edges. Homophilic interactions are associated with dimerization of isoforms of PRR2 and lead to the tyrosine phosphorylation of PRR2δ. Altogether, these results suggest that homophilic properties of PRR2 could participate to the regulation of hematopoietic/endothelial cell functions.

Abstract
We report on the functional cloning of a hitherto unknown member of the immunoglobulin (Ig) superfamily selected for its ability to confer susceptibility to herpes simplex virus (HSV) infection on a highly resistant cell line (J1.1-2 cells), derived by exposure of BHKtk- cells to a recombinant HSV-1 expressing tumor necrosis factor alpha (TNF-alpha). The sequence of herpesvirus Ig-like receptor (HIgR) predicts a transmembrane protein with an ectodomain consisting of three cysteine-bracketed domains, one V-like and two C-like. HIgR shares its ectodomain with and appears to be an alternative splice variant of the previously described protein PRR-1 (poliovirus receptor-related protein). Both HIgR and PRR-1 conferred on J1.1-2 cells susceptibility to HSV-1, HSV-2, and bovine herpesvirus 1. The viral ligand of HIgR and PRR-1 is glycoprotein D, a constituent of the virion envelope long known to mediate viral entry into cells through interaction with cellular receptor molecules. Recently, PRR-1, renamed HveC (herpesvirus entry mediator C), and the related PRR-2, renamed HveB, were reported to mediate the entry of HSV-1, HSV-2, and bovine herpesvirus 1, and the homologous poliovirus receptor was reported to mediate the entry of pseudorabies virus (R. J. Geraghty, C. Krummenacher, G. H. Cohen, R. J. Eisenberg, and P. G. Spear, Science 280:1618-1620, 1998; M. S. Warner, R. J. Geraghty, W. M. Martinez, R. I. Montgomery, J. C. Whitbeck, R. Xu, R. J. Eisenberg, G. H. Cohen, and P. G. Spear, Virology 246:179-189, 1998). Here we further show that HIgR or PRR-1 proteins detected by using a monoclonal antibody to PRR-1 are widely distributed among human cell lines susceptible to HSV infection and commonly used for HSV studies. The monoclonal antibody neutralized virion infectivity in cells transfected with HIgR or PRR-1 cDNA, as well as in the human cell lines, indicating a direct interaction of virions with the receptor molecule, and preliminarily mapping this function to the ectodomain of HIgR and PRR-1. Northern blot analysis showed that HIgR or PRR-1 mRNAs were expressed in human tissues, with the highest expression being detected in nervous system samples. HIgR adds a novel member to the cluster of Ig superfamily members able to mediate the entry of alphaherpesviruses into cells. The wide distribution of HIgR or PRR-1 proteins among human cell lines susceptible to HSV infection, coupled with the neutralizing activity of the antibody in the same cells, provides direct demonstration of the actual use of this cluster of molecules as HSV-1 and HSV-2 entry receptors in human cell lines. The high level of expression in samples from nervous system makes the use of these proteins in human tissues very likely. This cluster of molecules may therefore be considered to constitute bona fide receptors for HSV-1 and HSV-2.

Abstract
Certain mutant strains of herpes simplex virus type 1 (HSV-1) are unable to infect cells in which entry is dependent on HVEM, the previously described herpesvirus entry mediator designated here as herpesvirus entry protein A (HveA). These mutant viruses can infect other cells where entry is apparently dependent on other co-receptors. The mutant virus HSV-1(KOS)Rid1 was used to screen a human cDNA expression library for ability of transfected plasmids to convert resistant Chinese hamster ovary cells to susceptibility to virus entry. A plasmid expressing the previously described poliovirus receptor-related protein 2 (Prr2) was isolated on the basis of this activity. This protein, designated here as HveB, was shown to mediate the entry of three mutant HSV-1 strains that cannot use HVEM as co-receptor, but not wild-type HSV-1 strains. HveB also mediated the entry of HSV-2 and pseudorabies virus but not bovine herpesvirus type 1. HveB was expressed in some human neuronal cell lines, fibroblastic cells, keratinocytes, and primary activated T lymphocytes. Antibodies specific for HveB blocked infection of HveB-expressing CHO cells and a human fibroblastic cell strain HEL299. Differences in ability of HSV-1 and HSV-2 strains to use HveB for entry should influence the types of cells that can be infected and thereby account in part for serotype and strain differences in tissue tropism and pathogenicity.

Abstract
Polypeptides of amino acids 1 to 241 (PVR241) and 1 to 330 (PVR330) of the human poliovirus receptor (hPVR) were produced in a baculovirus expression system. PVR241 contained extracellular domains 1 and 2 of hPVR, and PVR330 contained extracellular domains 1, 2, and 3. These peptides were purified by immunoaffinity column chromatography with an anti-hPVR monoclonal antibody (MAb). After the purification, PVR241 and PVR330 appeared to retain their native conformation as judged by reactivity with an anti-PVR MAb that recognized domain 1 of hPVR in a conformation-dependent manner. The virulent Mahoney strain of poliovirus type 1 was mixed with the purified PVRs in various concentrations. An average of at least 43 PVR330 molecules were able to bind to one virion particle under the conditions used. The equilibrium dissociation constant between the PVR330 molecule and the PVR binding site (canyon) on the virion was determined to be 4.50 +/- (0.86) x 10(-8) M at 4 degrees C. Higher rates of conformational change of the virus (160S) to 135S and 80S particles were observed as the concentration of PVR330 was increased. In this in vitro system, the ratio of the amount of the 135S particle to that of the 80S particle seemed to be always constant. After the disappearance of the 160S particle, the amount of the 80S particle was not increased by further incubation at 37 degrees C. These results suggested that the 80S particle was not derived from the 135S particle under the conditions used in this study.

Abstract
The cellular receptors for poliovirus (PVR) are glycoproteins belonging to the immunoglobulin superfamily. Functional receptors for poliovirus are only expressed by primates; known rodent homologues lack the ability to bind virus due to amino acid differences. Human poliovirus infections are targeted to the gastrointestinal tract and, rarely, to motor neurons in the central nervous system. Available evidence suggests that poliovirus uses only one cellular receptor, implying that the tissue tropism of poliovirus is likely to be related to the expression of the human PVR (hPVR). However, low levels of expression of hPVR-specific mRNAs can be detected in many human tissues other than the apparent target cells. The nonpathogenic function of hPVR is unknown. For a study of the transcriptional control of hPVR expression, we have isolated and characterized the promoter of the hPVR gene. Deletion analysis defined an approximately 280 base pair minimal promoter fragment that: 1) lacks TATA- and CAAT-like elements, 2) is distinguished by a high GC content, and 3) promotes transcription at multiple start sites. The pattern of activity caused by transfection of serial 5'- and 3'-promoter deletions is almost identical in HEp2, HeLa, COS-1, and mouse L929 cells, indicating a similar transcriptional regulation of the hPVR promoter in these cell lines. However, on transfection of Raji cells, a Burkitt's lymphoma cell line harboring a transcriptionally inactive hPVR gene, all promoter reporter constructs tested exerted only residual activity. These results suggest that the cis-element(s) governing cell type-specific hPVR expression resides in the minimal promoter region. We also report the sequences of the promoters of two monkey homologues to hPVR (AGMalpha1 and AGMalpha2). Transcripts encoding the monkey poliovirus receptors originate from a region analogous to that identified for hPVR transcripts.

Abstract
Very little is known about the mechanism of cell entry of hepatitis A virus (HAV), and the identification of cellular receptors for this picornavirus has been elusive. Here we describe the molecular cloning of a cellular receptor for HAV using protective monoclonal antibodies raised against susceptible African green monkey kidney (AGMK) cells as probes. Monoclonal antibodies 190/4, 235/4 and 263/6, which reacted against similar epitopes, specifically protected AGMK cells against HAV infection by blocking the binding of HAV. Expression cloning and nucleotide sequence analysis of the cDNA coding for epitope 190/4 revealed a novel mucin-like class I integral membrane glycoprotein of 451 amino acids, the HAV cellular receptor 1 (HAVcr-1). Immunofluorescence analysis indicated that mouse Ltk- cells transfected with HAVcr-1 cDNA gained limited susceptibility to HAV infection, which was blocked by treatment with monoclonal antibody 190/4. Our results demonstrate that the HAVcr-1 polypeptide is an attachment receptor for HAV and strongly suggest that it is also a functional receptor which mediates HAV infection. This report constitutes the first identification of a cellular receptor for HAV.

Abstract
Until now it was assumed that the murine poliovirus (PV) receptor homolog gene (MPH) had been identified. Alternative splicing of MPH transcripts generates two glycoproteins named MPH alpha and MPH beta which share an identical N-terminal region composed of three immunoglobulin (Ig)-like domains and different C-terminal regions. Using a degenerate PCR strategy, we describe the identification of a second human PVR-related gene (PRR2), which encodes two glycoproteins, PRR2 alpha (short form) and PRR2 delta (long form). They present 69 and 73% identity with MPH alpha and MPH beta, respectively. In contrast, the human PVR protein exhibits 51% identity which is moreover restricted to the three Ig domains of the murine protein. We therefore propose that PRR2, and not PVR, is the true human homolog of MPH. In addition, Northern blot analysis showed that two mRNA isoforms of 3.0 kb (PRR2 alpha) and 4.4 kb (PRR2 delta) are ubiquitously found in various normal human tissues. In situ hybridization allowed us to map PRR2 to the 19q13.2-q13.4 bands of the human genome, in the same chromosomal region as PVR.

Abstract
The host range of poliovirus is determined by the expression of the hPVR, a member of the immunoglobulin superfamily. We characterized hPVR proteins biochemically and found them to be complex-type glycoproteins. The outermost V-like domain of three extracellular domains harbors the PVR function. A panel of single or multiple amino acid exchanges were introduced throughout this domain in order to localize regions involved in virus-receptor interactions. Putative contact amino acids were found to reside in the C'C"D and DE regions. Binding and uptake of poliovirus paralleled virus replication in all mutants tested suggesting that virus binding was affected without abrogating the ability to mediate subsequent events in the infection. Although the primate PVR is essential in conferring susceptibility to poliovirus infection, certain strains can induce neurological disease in rodents. Mouse neurovirulent PV isolates of divergent serotypical origin each provoked a distinctive, characteristic neurological syndrome upon intracerebral infection of wild-type mice. We analyzed clinical and histopathological features of diffuse encephalomyelitis caused by these PV strains and compared the condition with poliomyelitis in mice transgenic for the hPVR. Diffuse PV encephalomyelitis in wild-type mice could be distinguished clinically and histopathologically from hPVR-mediated poliomyelitis in trangenic mice. We localized the determinants of mouse neurovirulence of PV1(LS-a), a derivative of PV1 (Mahoney), in a portion of the viral genome encompassing parts of the capsid protein VP1 as well as the nonstructural protein 2A. Mouse neuropathogenicity could possibly be conferred by reduced particle stability of PV1(LS-a) inasmuch as we found particles to be thermolabile.

Abstract
The human poliovirus (PV) receptor (PVR) is a member of the immunoglobulin (Ig) superfamily with unknown cellular function. We have isolated a human PVR-related (PRR) cDNA. The deduced amino acid (aa) sequence of PRR showed, in the extracellular region, 51.7 and 54.3% similarity with human PVR and with the murine PVR homolog, respectively. The cDNA coding sequence is 1.6-kb long and encodes a deduced 57-kDa protein; this protein has a structural organization analogous to that of PVR, that is, one V- and two C-set Ig domains, with a conserved number of aa. Northern blot analysis indicated that a major 5.9-kb transcript is present in all normal human tissues tested. In situ hybridization showed that the PRR gene is located at bands q23-q24 of human chromosome 11.

Abstract
Poliomyelitis as a consequence of poliovirus infection is observed only in primates. Despite a host range restricted to primates, experimental infection of rodents with certain genetically well defined poliovirus strains produces neurological disease. The outcome of infection of mice with mouse-adapted poliovirus strains has been described previously mainly in terms of paralysis and death, and it was generally assumed that these strains produce the same disease syndromes in normal mice and in mice transgenic for the human poliovirus receptor (hPVR-tg mice). We report a comparison of the clinical course and the histopathological features of neurological disease resulting from intracerebral virus inoculation in normal mice with those of murine poliomyelitis in hPVR-tg mice. The consistent pattern of clinical deficits in poliomyelitic transgenic mice contrasted with highly variable neurologic disease that developed in mice infected with different mouse-adapted polioviruses. Histopathological analysis showed a diffuse encephalomyelitis induced by specific poliovirus serotype 2 isolates in normal mice, that affected neuronal cell populations without discrimination, whereas in hPVR-tg animals, damage was restricted to spinal motor neurons. Mouse neurovirulent strains of poliovirus type 2 differed from mouse neurovirulent poliovirus type 1 derivatives in their ability to induce CNS lesions. Our findings indicate that the characteristic clinical appearance and highly specific histopathological features of poliomyelitis are mediated by the hPVR.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Poliovirus type 1 strain LS-a [PV1(LS-a)] is a OV variant adapted to mice by multiple passages through mouse and monkey tissues. To investigate the molecular basis underlying mouse neurovirulence of PV1(LS-a), a cDNA of the viral genome containing nucleotides 112 to 7441 was cloned, and the nucleotide sequence was determined. Compared with that of the mouse avirulent progenitor PV1(Mahoney), 54 nucleotide changes were found in the genome of the PV1(LS-a) virus, resulting in 20 amino acid substitutions in the virus polyprotein. Whereas the nucleotide changes were scattered throughout the genome, the amino acid substitutions were largely clustered in the capsid proteins and, to a certain extent, in the virus proteinase 2Apro. By in vitro mutagenesis, PV1(LS-a)-specific capsid mutations were introduced into a cDNA clone of PV1(Mahoney). We show that neither the individual amino acid mutations nor combinations of mutations in the region encoding VP1 conferred to PV1(Mahoney) the mouse-adapted phenotype of PV1(LS-a). Chimeric cDNA studies demonstrated that a recombinant type 1 virus containing the PV1(LS-a) sequence from nucleotide 2470 to nucleotide 3625 displayed a neurovirulent phenotype in mice. Further dissection of this region revealed that mouse neurovirulence of PV1(LS-a) was determined by multiple mutations in regions encoding both viral proteinase 2Apro and capsid protein VP1. The mouse neurovirulent viruses, PV1(LS-a), W1-M/LS-Pf [nucleotides 496 to 3625 from PV1(LS-a)], and W1-M/LS-NP [nucleotides 2470 to 3625 from PV1(LS-a)], showed increased sensitivity to heat treatment at 45 degrees C for 1 h. Surprisingly, the thermolabile phenotype was also displayed by a recombinant of PV1(Mahoney) carrying a PV1(LS-a) DNA fragment encoding the N-terminal portion of 2Apro. This suggests that base substitutions in the region encoding 2Apro affected capsid stability, thereby contributing to the neurovirulence of the virus in mice.

Abstract
The human receptors for poliovirus (hPVR) are members of the immunoglobulin superfamily. Whereas the two membrane-bound isoforms, hPVR alpha and hPVR delta, share identical three-domain extracellular portions, their C-terminal cytoplasmic parts differ considerably. This feature is well conserved in the corresponding monkey proteins AGM alpha 1, AGM delta 1, and AGM alpha 2. The cellular function of these proteins is presently unknown. In this short communication we report that hPVR alpha and possibly also AGM alpha 1 and AGM alpha 2, but not the delta isoforms, are phosphoproteins. The phosphorylation occurs at a serine in the cytoplasmic tails of these receptors. We further present evidence suggesting that the kinase responsible for the phosphorylation is calcium/calmodulin kinase II.

Abstract
Paralytic poliomyelitis is caused by the destruction of neurons in the central nervous system during the lytic replication of poliovirus. The human gene for the poliovirus receptor has been cloned recently, and transgenic mice generated that are susceptible to this virus. This has allowed the critical amino acids that determine the specificity of poliovirus to be identified.

Abstract
Picornaviruses are among the best understood animal viruses in molecular terms. A number of important human and animal pathogens are members of the Picornaviridae family. The genome organization, the different steps of picornavirus growth and numerous compounds that have been reported as inhibitors of picornavirus functions are reviewed. The picornavirus particles and several agents that interact with them have been solved at atomic resolution, leading to computer-assisted drug design. Picornavirus inhibitors are useful in aiding a better understanding of picornavirus biology. In addition, some of them are promising therapeutic agents. Clinical efficacy of agents that bind to picornavirus particles has already been demonstrated.
