(CTG)n repeats markedly inhibit differentiation of the C2C12 myoblast cell line: implications for congenital myotonic dystrophy. (1/2641)Although the mutation for myotonic dystrophy has been identified as a (CTG)n repeat expansion located in the 3'-untranslated region of a gene located on chromosome 19, the mechanism of disease pathogenesis is not understood. The objective of this study was to assess the effect of (CTG)n repeats on the differentiation of myoblasts in cell culture. We report here that C2C12 myoblast cell lines permanently transfected with plasmid expressing 500 bases long CTG repeat sequences, exhibited a drastic reduction in their ability to fuse and differentiate into myotubes. The percentage of cells fused into myotubes in C2 C12 cells (53.4+/-4.4%) was strikingly different from those in the two CTG repeat carrying clones (1.8+/-0.4% and 3.3+/-0. 7%). Control C2C12 cells permanently transfected with vector alone did not show such an effect. This finding may have important implications in understanding the pathogenesis of congenital myotonic dystrophy. (+info)
Morphogenesis of the Caenorhabditis elegans male tail tip. (2/2641)Using electron microscopy and immunofluorescent labeling of adherens junctions, we have reconstructed the changes in cell architecture and intercellular associations that occur during morphogenesis of the nematode male tail tip. During late postembryonic development, the Caenorhabditis elegans male tail is reshaped to form a copulatory structure. The most posterior hypodermal cells in the tail define a specialized, sexually dimorphic compartment in which cells fuse and retract in the male, changing their shape from a tapered cone to a blunt dome. Developmental profiles using electron microscopy and immunofluorescent staining suggest that cell fusions are initiated at or adjacent to adherens junctions. Anterior portions of the tail tip cells show the first evidence of retractions and fusions, consistent with our hypothesis that an anterior event triggers these morphogenetic events. Available mutations that interfere with morphogenesis implicate particular regulatory pathways and suggest loci at which evolutionary changes could have produced morphological diversity. (+info)
Isolation and partial characterization of Drosophila myoblasts from primary cultures of embryonic cells. (3/2641)We describe a method for preparing highly enriched cultures of Drosophila myoblasts from a heterogeneous cell population derived from gastrulating embryos. Enriched cultures are prepared by plating this heterogeneous population of cells in medium from which much of the free calcium is chelated by ethylene glycol-bis(beta-aminoethyl ether)N,N,N',N'-tetraacetate (EGTA). Adhesion of myoblasts to tissue culture plastic is better than that of other cell types when plated in this medium. Data concerning cell identity, timing of S phase, and fusion kinetics document the degree of enrichment for myogenic cells and illustrate their synchronous differentiation in vitro. (+info)
Mibefradil (Ro 40-5967) inhibits several Ca2+ and K+ currents in human fusion-competent myoblasts. (4/2641)1. The effect of mibefradil (Ro 40-5967), an inhibitor of T-type Ca2+ current (I(Ca)(T)), on myoblast fusion and on several voltage-gated currents expressed by fusion-competent myoblasts was examined. 2. At a concentration of 5 microM, mibefradil decreases myoblast fusion by 57%. At this concentration, the peak amplitudes of I(Ca)(T) and L-type Ca2+ current (I(Ca)(L)) measured in fusion-competent myoblasts are reduced by 95 and 80%, respectively. The IC50 of mibefradil for I(Ca)(T) and I(Ca)(L) are 0.7 and 2 microM, respectively. 3. At low concentrations, mibefradil increased the amplitude of I(Ca)(L) with respect to control. 4. Mibefradil blocked three voltage-gated K+ currents expressed by human fusion-competent myoblasts: a delayed rectifier K+ current, an ether-a-go-go K+ current, and an inward rectifier K+ current, with a respective IC50 of 0.3, 0.7 and 5.6 microM. 5. It is concluded that mibefradil can interfere with myoblast fusion, a mechanism fundamental to muscle growth and repair, and that the interpretation of the effect of mibefradil in a given system should take into account the action of this drug on ionic currents other than Ca2+ currents.

Analysis of masked mutations in familial adenomatous polyposis. (5/2641)Familial adenomatous polyposis (FAP) is an autosomal-dominant disease characterized by the development of hundreds of adenomatous polyps of the colorectum. Approximately 80% of FAP patients can be shown to have truncating mutations of the APC gene. To determine the cause of FAP in the other 20% of patients, MAMA (monoallelic mutation analysis) was used to independently examine the status of each of the two APC alleles. Seven of nine patients analyzed were found to have significantly reduced expression from one of their two alleles whereas two patients were found to have full-length expression from both alleles. We conclude that more than 95% of patients with FAP have inactivating mutations in APC and that a combination of MAMA and standard genetic tests will identify APC abnormalities in the vast majority of such patients. That no APC expression from the mutant allele is found in some FAP patients argues strongly against the requirement for dominant negative effects of APC mutations. The results also suggest that there may be at least one additional gene, besides APC, that can give rise to FAP. (+info)
Microtubule dynamics from mating through the first zygotic division in the budding yeast Saccharomyces cerevisiae. (6/2641)We have used time-lapse digital imaging microscopy to examine cytoplasmic astral microtubules (Mts) and spindle dynamics during the mating pathway in budding yeast Saccharomyces cerevisiae. Mating begins when two cells of opposite mating type come into proximity. The cells arrest in the G1 phase of the cell cycle and grow a projection towards one another forming a shmoo projection. Imaging of microtubule dynamics with green fluorescent protein (GFP) fusions to dynein or tubulin revealed that the nucleus and spindle pole body (SPB) became oriented and tethered to the shmoo tip by a Mt-dependent search and capture mechanism. Dynamically unstable astral Mts were captured at the shmoo tip forming a bundle of three or four astral Mts. This bundle changed length as the tethered nucleus and SPB oscillated toward and away from the shmoo tip at growth and shortening velocities typical of free plus end astral Mts (approximately 0.5 micrometer/min). Fluorescent fiduciary marks in Mt bundles showed that Mt growth and shortening occurred primarily at the shmoo tip, not the SPB. This indicates that Mt plus end assembly/disassembly was coupled to pushing and pulling of the nucleus. Upon cell fusion, a fluorescent bar of Mts was formed between the two shmoo tip bundles, which slowly shortened (0.23 +/- 0.07 micrometer/min) as the two nuclei and their SPBs came together and fused (karyogamy). Bud emergence occurred adjacent to the fused SPB approximately 30 min after SPB fusion. During the first mitosis, the SPBs separated as the spindle elongated at a constant velocity (0.75 micrometer/min) into the zygotic bud. There was no indication of a temporal delay at the 2-micrometer stage of spindle morphogenesis or a lag in Mt nucleation by replicated SPBs as occurs in vegetative mitosis implying a lack of normal checkpoints. Thus, the shmoo tip appears to be a new model system for studying Mt plus end dynamic attachments and much like higher eukaryotes, the first mitosis after haploid cell fusion in budding yeast may forgo cell cycle checkpoints present in vegetative mitosis.

Effects of double-site mutations of vesicular stomatitis virus glycoprotein G on membrane fusion activity. (7/2641)Site-directed mutagenesis of specific amino acids within a conserved amino-terminal region (H2) and a conserved carboxyl-terminal region (H10/A4) of the fusion protein G of vesicular stomatitis virus have previously identified these two segments as an internal fusion peptide and a region influencing low-pH induced conformational change, respectively. Here, we combined a number of the substitution mutants in the H2 and H10/A4 regions to produce a series of double-site mutants and determined the effect of these mutations on membrane fusion activity at acid pH and on pH-dependent conformational change. The results show that most of the double-site mutants have decreased cell-cell fusion activity and that the effects appeared to be additive in terms of inhibition of fusion, except for one mutant, which appeared to be a revertant. The double-site mutants also had pH optima for fusion that were lower than those observed with wild-type G but same as the pH optima for the parent fusion peptide (H2) mutants. The results suggest that although the H2 and H10/A4 sites may affect membrane fusion independently, a possible interaction between these two sites cannot be ruled out. (+info)
Rapid visualization of metaphase chromosomes in single human blastomeres after fusion with in-vitro matured bovine eggs. (8/2641)The present study was aimed to facilitate karyotyping of human blastomeres using the metaphase-inducing factors present in unfertilized eggs. A rapid technique for karyotyping would have wide application in the field of preimplantation genetic diagnosis. When cryopreserved in-vitro matured bovine oocytes were fused with human blastomeres, the transferred human nuclei were forced into metaphase within a few hours. Eighty-seven human blastomeres from abnormal or arrested embryos were fused with bovine oocytes in a preclinical study. Fusion efficiency was 100%. In 21 of the hybrid cells, no trace of human chromatin was found. Of the remaining 66, 64 (97%) yielded chromosomes suitable for analysis. The method was used to karyotype embryos from two patients with maternal translocations. One embryo which was judged to be karyotypically normal was replaced in the first patient, resulting in one pregnancy with a normal fetus. None of the second patient's embryos was diagnosed as normal, and hence none was transferred. The results of the present study demonstrated that the ooplasmic factors which induce and maintain metaphase in bovine oocytes can force transferred human blastomere nuclei into premature metaphase, providing the basis for a rapid method of karyotyping blastomeres from preimplantation embryos and, by implication, cells from other sources.

Studies of membrane fusion. VI. Mechanism of the membrane fusion and cell swelling stages of Sendai virus-mediated cell fusion ...
The membrane fusion and cell swelling stages of Sendai virus-mediated cell-cell fusion have been studied by thin-section and freeze-fracture electron microscopy. Sites of membrane fusion have been detected in human erythrocytes arrested at the membrane fusion stage of cell fusion and in virtually all cases a fused viral envelope or envelope components has been identified thus providing further direct evidence that cell-viral envelope-cell bridge formation is the membrane fusion event in Sendai virus-induced cell fusion. Radial expansion of a single virus bridge connecting 2 cells is sufficient to produce a fused cell. Membrane redistribution which occurs during this cell swelling stage of the fusion process is often accompanied by the formation of a system of membrane tubules in the plane of expansion of the virus bridge. The tubules originate from points of fusion between the bridging virus envelope and the erythrocyte membrane and also expand radially as cells swell. Ultimately membrane ...
Moreover, within the body fusion of myoblasts and formation of multinucleate fibers may be exemplified. They can also be allowed to fuse in vitro and form heterokaryons. Macrophages fuse around the foreign body or bacterial cells in the tissues. Bone cells are also known to undergo somatic cell fusion. Cells growing in culture are induced by some of the viruses such as Sendai virus to fuse and form hybrids. This virus induces two different cells first to form heterokaryon (Fig. 6.7). During mitosis chromosome of heterokaryons are brought towards two poles which later on fuse to form hybrids. Removal of surface carbohydrates is necessary before establishment of cell fusion. Some chemicals such as polyethylene glycol also induce somatic cell fusion. It is interesting to note that the cells of taxonomically different animals can fuse and form hybrids. This suggests that there is no compatibility between membranes, nuclei, organelles of two different groups of animal cells (Sidebottom and ...

Tissue regeneration after injury poses a major challenge that requires the fine balance between stimulation and dysregulation of cell proliferation in order to facilitate homeostatic repair. We have shown that fusion between circulating bone marrow-derived cells (BMDCs) and non-hematopoietic cells occurs in response to intestinal epithelial injury as a potential regenerative mechanism. We suggest that fusion also occurs in tumorigenesis based upon the observation of shared microenvironments between injury and tumor models. However, the cellular and environmental requirements for intestinal cell fusion remain unknown. Importantly, the physiologic impact of cell fusion on epithelial homeostasis and tumorigenesis has not been defined. Therefore, to investigate the physiologic relevance of this process in repair and disease, the work in this thesis will test the hypothesis that cell fusion hybrids represent a unique cellular population, retaining characteristics of both parental fusogenic populations.

Cell fusion is an important cellular process in which several uninuclear cells (cells with a single nucleus) combine to form a multinuclear cell, known as a syncytium. Cell fusion occurs during differentiation of muscle, bone and trophoblast cells, during embryogenesis, and during morphogenesis. Cell fusion is a necessary event in the maturation of cells so that they maintain their specific functions throughout growth. In 1847 Theodore Schwann expanded upon the theory that all living organisms are composed of cells when he added to it that discrete cells are the basis of life. Schwann observed that in certain cells the walls and cavities of the cells coalesce together. It was this observation that provided the first hint that cells fuse. It was not until 1960 that cell biologists deliberately fused cells for the first time. To fuse the cells, biologists combined isolated mouse cells, with the same kind of tissue, and induced fusion of their outer membrane using the Sendai virus (a respiratory ...

EFF-1 and AFF-1 can fuse epithelial and myoepithelial cells in C. elegans, in heterologous Sf9 insect cells and in BHK hamster cells. This is a proof of principle that will allow us to test potential fusogens involved in mammalian myoblast fusion [5,10,11]. While candidates for muscle fusogens exist in Drosophila and vertebrates [1,12,13] none of these candidates has been shown to be both essential and sufficient for the cell membrane fusion process. Instead, the many genes involved in muscle cell fusion may be acting in earlier stages in the process that include: cell cycle arrest, recognition, alignment and adhesion (Fig. 1). We use a molecular genetic approach to identify the mammalian myoblast fusogen using expression of candidate genes in BHK cells and complementation of a C. elegans eff-1 deletion mutant with cross species expression of mouse cDNAs expressed during muscle formation. The approach and rationale is novel, risky and with extremely high potential of making a very important ...

Carcinogenesis is a sophisticated biological process consisting of a series of progressive changes in somatic cells from premalignant to malignant phenotype. Despite the vast information available about cancer cells, the origin of cancer and cause of metastasis still remain enigmatic. The hypothesis of cell fusion is one of several models explaining the evolution of neoplasia into clinically significant cancer. This theory states that cancer cells through heterotypic fusion with host cells generate hybrids expressing traits from both parental cells, and acquire metastatic potentials and growth-promoting properties. The cell fusion theory is still unproven and speculative, but cell fusion is a common biological process in normal tissue. Accumulated evidence shows that macrophage-cancer cell fusion occurs in vitro and in vivo and produces hybrids with metastatic potential, but the clinical significant of cell fusion is unclear. The aim of this thesis is to test this hypothesis in clinical patient ...

Introduction] Recent reports demonstrating the ability of bone marrow (BM) cells to regenerate cardiomyocytes (CMs) have prompted clinical as well as basic studies for the treatment of ischemic and non-ischemic cardiomyopathies. However, the responsible BM cells and underlying mechanism of regeneration remain unclear. In this study, we checked the cardiomyogenic potential of BM cells in vivo, to identify the cell populations in BM that possess the capacity to give rise to CMs and clarify whether cardiomyogenic potential of BM-derived cells require cell fusion with host CMs.. [Method and Result] BM cells of mice constitutively expressing green fluorescent protein (GFP) was intravenously injected into irradiated syngeneic newborn C57BL/6 mouse within 48hours after the birth. At 4-5weeks after transplantation, the cardiac tissue of recipients was analyzed for the number of GFP+ CMs per 40 sections. We first separated Linaege antigen− BM cells to CD45+ cells (Lin−CD45+) and CD45− cells ...

Regulatory and biophysical mechanisms of cell-cell fusion are largely unknown, despite the fundamental requirement for fused cells in eukaryotic development. Only two cellular fusogens that are not of obvious viral origin have been identified to date, both in nematodes. EFF-1 and AFF-1 comprise the FF family and together they are necessary for virtually all somatic cell fusions in C. elegans. Unregulated EFF-1 expression causes lethality due to ectopic fusion between cells not developmentally programmed to fuse, highlighting the necessity of tight fusogen regulation for proper development. ^ Identifying factors that regulate EFF-1 and its paralog AFF-1 could lead to discovery of molecular mechanisms that control cell fusion upstream of the action of a membrane fusogen. Yet, FF proteins are sufficient to fuse heterologous invertebrate cell types, suggesting that they function autonomously in foreign molecular and proteomic environments. The work presented here examines whether a predicted 14-3-3

Myeloid and lymphoid contribution to non-haematopoietic lineages through irradiation-induced heterotypic cell fusion. -...
Recent studies have suggested that regeneration of non-haematopoietic cell lineages can occur through heterotypic cell fusion with haematopoietic cells of the myeloid lineage. Here we show that lymphocytes also form heterotypic-fusion hybrids with cardiomyocytes, skeletal muscle, hepatocytes and Purkinje neurons. However, through lineage fate-mapping we demonstrate that such in vivo fusion of lymphoid and myeloid blood cells does not occur to an appreciable extent in steady-state adult tissues or during normal development. Rather, fusion of blood cells with different non-haematopoietic cell types is induced by organ-specific injuries or whole-body irradiation, which has been used in previous studies to condition recipients of bone marrow transplants. Our findings demonstrate that blood cells of the lymphoid and myeloid lineages contribute to various non-haematopoietic tissues by forming rare fusion hybrids, but almost exclusively in response to injuries or inflammation.
We used the in vivo ER fusion assay to determine whether the rate of fusion decreases in ufe1-1 cells. When ufe1-1 cells were mated at permissive temperature (23°C), ER fusion occurred ∼5 min after cell fusion (Fig. 3 c), similar to what was found for wild-type cells (Fig. 2 e). It was not possible to perform this assay with cells shifted to a nonpermissive temperature (37°C) immediately before mating because yeast will not mate at this temperature (Grote, 2010). Instead, we shifted cells to 32°C just before mating. At this temperature, ufe1-1 strains were viable but grew much more slowly than wild-type cells (unpublished data), suggesting that Ufe1p function is substantially reduced at this temperature. When ufe1-1 cells were mated at 32°C, ER fusion occurred a mean of ∼10 min after cell fusion (Fig. 3 c), indicating that these cells have a modest fusion defect. At this temperature, cells missing only Sey1p fused their ER ∼16 min after cell fusion (Fig. 3 c), somewhat faster than at ...
Myoblast fusion is regulated by a prostanoid of the one series independently of a rise in cyclic AMP. | Journal of Cell Biology...
The role of prostanoids in the regulation of chick myoblast differentiation has been investigated. At 3 X 10(-6) M, indomethacin and chloroquine specifically inhibit cell fusion. They do not affect cell proliferation, alignment, or the expression of two muscle-specific proteins, namely, the acetylcholine receptor and the muscle-specific form of creatine phosphokinase. The results demonstrate that it is indomethacins activity as an inhibitor of prostaglandin synthesis at the cyclooxygenase step that causes the block of cell fusion, whereas chloroquine probably acts at the earlier step of phospholipase A. Prostaglandin E1 (PGE1), but not prostaglandin E2 (PGE2), rapidly reverses the inhibition of fusion imposed by indomethacin or chloroquine. The dose response of the myoblasts to PGE1 is a bell-shaped curve with a 100% reversal of fusion at approximately 10(-9) M. Eicosatrienoate and linoleate reverse the inhibition of fusion with similar kinetics, whereas arachidonate is completely ineffective. ...

Actin-propelled invasive membrane protrusions promote fusogenic protein engagement during cell-cell fusion. | Department of...
Cell-cell fusion is critical for the conception, development, and physiology of multicellular organisms. Although cellular fusogenic proteins and the actin cytoskeleton are implicated in cell-cell fusion, it remains unclear whether and how they coordinate to promote plasma membrane fusion. We reconstituted a high-efficiency, inducible cell fusion culture system in the normally nonfusing Drosophila S2R+ cells. Both fusogenic proteins and actin cytoskeletal rearrangements were necessary for cell fusion, and in combination they were sufficient to impart fusion competence. Localized actin polymerization triggered by specific cell-cell or cell-matrix adhesion molecules propelled invasive cell membrane protrusions, which in turn promoted fusogenic protein engagement and plasma membrane fusion. This de novo cell fusion culture system reveals a general role for actin-propelledinvasive membrane protrusions in driving fusogenic protein engagement during cell-cell fusion.. ...

Skeletal muscle formation depends on the fusion of mononucleated myoblasts into multinucleated myotubes. Myoblast fusion is also the basis of muscle growth and repair during postnatal life. The ability of myoblasts to fuse and thereby inject their nucleus into existing muscle fibers led to several preclinical and clinical trials aimed at treating both muscle and non-muscle-related disorders. Identifying the pattern of events that induce myoblast differentiation and their commitment to fuse would benefit the search for improving myoblast-based therapies.. Using primary myoblast cultures derived from single human satellite cells (Baroffio et al., 1993), we have previously shown that membrane potential and the biophysical properties of specific ionic channels are important actors in the fusion process. We found that human myoblasts hyperpolarize before fusion through the sequential expression of two different K+ channels, ether-à-go-go (EAG) K+ channels (Bijlenga et al., 1998; Occhiodoro et al., ...
We are pursuing three projects that extend from our interests in the development of tissues and the innovative application of light microscopy to biology: Developmental cell fusion, Second-harmonic generation microscopy, and Genome-wide imaging of C. elegans development. Developmental Cell Fusion Formation of multinucleate syncytia (giant cells) is essential to the development and regeneration of human skeletal muscle, and is key to fertilization and the formation of various specialized cell types in many species. Yet the mechanism by which fusing cells recognize each other and merge their membranes is poorly understood. We use genetics and microscopy in the nematode worm C. elegans to study the mechanisms by which cells fuse during this animals development. Our recent studies of the unique cell-fusion protein EFF-1 indicate that the molecular machinery of cell fusion has been re-invented during evolution of different cell types and divergent organisms. We are also investigating the mechanism ...
The Chen lab studies mechanisms underlying cell-cell fusion, a fundamental cellular process in the conception, development and physiology of multicellular organisms. We approach this question using a multifaceted approach including genetics, molecular biology, biochemistry, biophysics, live imaging, super-resolution microscopy and electron microscopy. Starting with a forward genetic screen in Drosophila, we have identified multiple evolutionarily conserved core components of the myoblast fusion signaling cascade, and, more importantly, discovered a novel cellular mechanism underlying myoblast fusion. We show that myoblast fusion is an asymmetric process in which one cell invades its fusion partner using actin-propelled membrane protrusions to promote fusion pore formation. Building on insights we learned from myoblast fusion in vivo, we have reconstituted high-efficiency cell-cell fusion in an otherwise non-fusogenic, non-muscle cell line and uncovered a previously unrecognized function for the ...

Human rectal tumor-18 (HRT-18) cell clones 3F3, 3E3, D2, and 4B3 exhibited differences in cellular morphology in Giemsa-stained cultures and developing monolayers. Differences were evident in growth kinetics and plating efficiency of each clone. The clones produced colonies in soft agar, demonstrating anchorage independence. Cytopathic expression (CPE) including cytoplasmic vacuolization and cell fusion occurred in BCV-L9-infected clones 3F3, D2, and 3E3. Cell fusion was inapparent in clone 4B3. Bovine coronavirus strain L9 (BCV-L9) and 5 wild-type isolates replicated in HRT-18 cells, inducing cell fusion. Strain L9, exclusively, replicated in D2BFS cells, requiring trypsin to induce cell fusion. Strain L9 produced plaques in the HRT-18 clones, but the ease of plaque formation and plaque morphology was host cell dependent. Host cell-dependent plaque formation was demonstrated by wild-type BCV strains, and plaque morphology was strain dependent. The intensity of trypsin enhancement of CPE and plaque

Isomerization of the intersubunit disulphide‐bond in Env controls retrovirus fusion | The EMBO Journal
The possibility that isomerization controls the fusion activity was tested by analysing Mo‐MLV fusion and infectivity under conditions that either inhibited or induced isomerization. The fusion was studied as virus‐induced polykaryon formation in XC cells (fusion‐from‐without). Fusion of cell‐bound virus is induced by incubation at 37°C and terminated by pH 3.0 treatment. In confluent cultures (Figure 6A), the fusion will merge cells, and with time these will rearrange into polykaryons (Figure 6B). Preliminary testing demonstrated that TN/1.8 mM Ca2+ supported fusion as effectively as DMEM (data not shown). Therefore, TN/1.8 mM Ca2+ was used as the control condition. The time course of the fusion process is shown in Figure 6C.. We first studied the effect that alkylation‐mediated inhibition of isomerization had on fusion. To avoid adverse effects due to alkylation of internal viral proteins, we used the membrane‐impermeant reagents M135 and MTSET. We observed a ...

PRR determinants controlling cell-to-cell and virus-to-cell fusion thresholds.As inferred from the results of syncytium assays, MLV-4070A glycoproteins harboring mutations in the PRR, such as PROMO, PROFR, A2, and A3, appeared more readily fusogenic in cell-to-cell fusion assays and thus seemed more reactive than wild-type amphotropic envelopes. They may thus require fewer PiT-2 amphotropic receptors to trigger their cell-to-cell fusogenicity. To test the relationship between increased fusogenicity and requirements for PiT-2 receptor molecules, we compared cell-to-cell fusion to either XC or XC-A-ST cells. In the latter, constitutive expression of an interfering amphotropic BD reduced the number of available functional PiT-2 receptors as demonstrated by the reduced capacities of either PROMO or MLV-4070A envelope glycoproteins to bind XC-A-ST cells compared to that of parental XC cells (see Fig. 5A). As expected, this resulted in an inhibition of fusion of XC-A-ST cells through cell-to-cell ...

The classical method of producing diagnostic and therapeutic monoclonal antibodies (mAbs) is to fuse Ab-producing B-cells with cancerous mouse cells (hybridoma technology). The product of this cellular fusion serves as a source for the production of mAbs in vitro or in vivo. In either case large numbers of animals (i.e. syngeneic mice for in vivo production) or large amounts of animal products (fetal calf serum for in vitro production) are required. In addition, the syngeneic mice are, depending on the treatment and the type of adjuvants applied, often exposed to high physical stress. In addition, if these mAb would be used in humans they would have to be engineered to contain only human DNA-sequences in their framework (humanization). We would like to replace these cumbersome and - in terms of animals sacrificed or fetal calf serum consumed - very intense procedures by a technology which starts directly with the immunological profile of human antigen-specific B-cells to produce pure human ...

An analysis of the R18 fusion assay was made during the fusion of the Sendai virus with erythrocyte ghosts. The increase in R18 fluorescence, reflecting the interaction process, was evaluated in terms of the different processes that in principle may contribute to this increase, that is, monomeric probe transfer, hemifusion, and complete fusion. To this end, the kinetics of the R18-labeled lipid mixing were compared to those obtained with an assay in which the fusion-monitoring probe, eosin-maleimide, was attached to the viral surface proteins. The experiments relied on the use of native and fusion-inactive viruses and studies involving viral and target membranes that were modified by the incorporation of the lysophospholipid. The total dequenching signal detected in the R18 assay consists of components from probe transferred without fusion and from fusion itself. At 37 degrees C, the initial rate of dequenching (within two minutes) was predominately from the probe diluted by fusion with little
In this paper, a myoblast fusion defect was attributed to mutation of the Drosophila melanogaster paramyosin gene. We now show that the fusion defect instead apparently arises from the TM3 balancer chromosome. Experiments subsequent to publication using a TM3-containing line that lacked a paramyosin mutation suggested that we had mis-identified balancer chromosome-containing individuals before the late embryonic stage as paramyosin mutant homozygotes (prm1/prm1). By using a lacZ-expressing version of TM3, staining experiments unambiguously identified young prm1 homozygotes and showed them all to lack the fusion defect, implying that the fusion defect is due to the presence of the TM3 chromosome. We have not tested whether this is a homozygous or heterozygous effect of TM3. The apparent rescue of the fusion defect by the wild-type paramyosin transgene is presumably due to the absence of the TM3 chromosome, instead of the presence of the paramyosin transgene. We conclude that embryos identified as ...

Multinucleated giant cells (MGCs), formed from macrophage fusion, occur as a consequence of a number of pathological conditions in the body. MGC formation can be particularly destructive to synthetic implants, as it etches their surface, and could lead to implant failure. Despite significant research into macrophage fusion, there are many underlying molecular events that are still unknown, and there are currently no systems that allow in vitro visualization of this process in living specimens. This is because there are no surfaces that promote macrophage fusion while maintaining the necessary optical properties for advanced imaging. Studies to determine the mechanisms modulating the formation and function of MGCs are needed, not only to identify ways to curb its destructive nature but also to better understand giant cell biology.. Researchers at Arizona State University and their collaborators developed a novel surface coating that promotes high rates of macrophage fusion and formation of ...
Human mesenchymal stem cells reprogram adult cardiomyocytes toward a progenitor-like state through partial cell fusion and...
Because stem cells are often found to improve repair tissue including heart without evidence of engraftment or differentiation, mechanisms underlying wound healing are still elusive. Several studies have reported that stem cells can fuse with cardiomyocytes either by permanent or partial cell fusion processes. However, the respective physiological impact of these two processes remains unknown in part because of the lack of knowledge of the resulting hybrid cells. To further characterize cell fusion, we cocultured mouse fully differentiated cardiomyocytes with human multipotent adipose-derived stem (hMADS) cells as a model of adult stem cells. We found that heterologous cell fusion promoted cardiomyocyte reprogramming back to a progenitor-like state. The resulting hybrid cells expressed early cardiac commitment and proliferation markers such as GATA-4, myocyte enhancer factor 2C, Nkx2.5, and Ki67 and exhibited a mouse genotype. Interestingly, human bone marrow-derived stem cells shared similar

Here, we used live cell imaging to show that actin-based protrusions at the leading edge initiate macrophage fusion. Phase-contrast video microscopy demonstrated that in the majority of events, short protrusions (∼3 µm) between two closely apposed cells initiated fusion, but occasionally we observed long protrusions (∼12 µm). Using macrophages isolated from LifeAct mice and imaging with lattice light sheet microscopy, we further found that fusion-competent protrusions formed at ...
The plasma membrane proteins Prm1 and Fig1 ascertain fidelity of membrane fusion during yeast mating. - Walter Lab
As for most cell-cell fusion events, the molecular details of membrane fusion during yeast mating are poorly understood. The multipass membrane protein Prm1 is the only known component that acts at the step of bilayer fusion. In its absence, mutant mating pairs lyse or arrest in the mating reaction with tightly apposed plasma membranes. We show that deletion of FIG 1, which controls pheromone-induced Ca(2+) influx, yields similar cell fusion defects. Although extracellular Ca(2+) is not required for efficient cell fusion of wild-type cells, cell fusion in prm1 mutant mating pairs is dramatically reduced when Ca(2+) is removed. This enhanced fusion defect is due to lysis. Time-lapse microscopy reveals that fusion and lysis events initiate with identical kinetics, suggesting that both outcomes result from engagement of the fusion machinery. The yeast synaptotagmin orthologue and Ca(2+) binding protein Tcb3 has a role in reducing lysis of prm1 mutants, which opens the possibility that the observed ...

Viruses | Free Full-Text | Evidence Showing that Tetraspanins Inhibit HIV-1-Induced Cell-Cell Fusion at a Post-Hemifusion Stage
Human immunodeficiency virus type 1 (HIV-1) transmission takes place primarily through cell-cell contacts known as virological synapses. Formation of these transient adhesions between infected and uninfected cells can lead to transmission of viral particles followed by separation of the cells. Alternatively, the cells can fuse, thus forming a syncytium. Tetraspanins, small scaffolding proteins that are enriched in HIV-1 virions and actively recruited to viral assembly sites, have been found to negatively regulate HIV-1 Env-induced cell-cell fusion. How these transmembrane proteins inhibit membrane fusion, however, is currently not known. As a first step towards elucidating the mechanism of fusion repression by tetraspanins, e.g., CD9 and CD63, we sought to identify the stage of the fusion process during which they operate. Using a chemical epistasis approach, four fusion inhibitors were employed in tandem with CD9 overexpression. Cells overexpressing CD9 were found to be sensitized to inhibitors
Common themes are emerging from the study of viral, cell-cell, intracellular, and liposome fusion. Viral and cellular membrane fusion events are mediated by fusion proteins or fusion machines. Viral fusion proteins share important characteristics, notably a fusion peptide within a transmembrane-anchored polypeptide chain. At least one protein involved in a cell-cell fusion reaction resembles viral fusion proteins. Components of intracellular fusion machines are utilized in multiple membrane trafficking events and are conserved through evolution. Fusion pores develop during and intracellular fusion events suggesting similar mechanisms for many, if not all, fusion events. ...

The present study demonstrates that Ito1 introduced into freshly isolated guinea pig myocytes by cell fusion substantially changes the early repolarization phase and abbreviates action potential duration. The role of Ito1 in the action potential has been previously assessed indirectly by comparison of Ito1 densities and action potentials throughout the layers of the myocardial wall (ie, humans,24 25 dogs,29 30 31 cats,32 rats,33 and rabbits34 ) or in disease states such as hypertrophy and heart failure.1 2 3 To further elucidate the role of Ito1, Ito1 has been blocked pharmacologically, knocked out by dominant-negative constructs, or artificially introduced into heart failure cells with brief repolarizing current pulses.2 6 33 35 However, K+ channel blockers such as 4-aminopyridine also exhibit nonspecific effects,33 current pulses may lack physiological current kinetics, and previous knockout studies were limited by changes of gene expression during cell culture6 or adaptive upregulation of ...
Myoblast implantation is a unique, patented technology of muscle regeneration being tested in Phase III clinical trials of muscular dystrophy, ischemic cardiomyopathy, Phase II trial of cancer, and Phase I trial of Type II diabetes. Differentiated and committed, myoblasts are not stem cells. Implanted myoblasts fuse spontaneously among themselves, replenishing genetically normal myofibers. They also fuse with genetically abnormal myofibers of muscular dystrophy, cardiomyopathy, or Type II diabetes, transferring their nuclei containing the normal human genome to provide stable, long-term expression of the missing gene products. They develop to become cardiomyocytes in the infracted myocardium. Myoblasts transduced with VEGF165 allow concomitant regeneration of blood capillaries and myofibers. They are potent biologics for treating heart failure, ischemic cardiomyopathy, diabetic ischemia, erectile dysfunction, and baldness. Myoblasts, because of their small size, spindle shape, and

This work demonstrates that virion-associated HLA-C molecules, when present on cells expressing gp120/gp41, significantly enhance fusion efficiency and pseudovirus transduction. Our conclusions are supported by the following findings: a) CHO cells co-expressing HIV-1 gp120/gp41 and human HLA-C fuse more rapidly and produce larger syncytia than the original CHO-gp120/gp41 cells from which they are derived; b) transient transfection of gp120/gp41 from different primary isolates in CHO cells co-expressing HLA-C results in a significant increase in fusion; c) silencing of HLA-C in human cell lines expressing HIV-1 gp120/gp41 of R5 and X4 tropic strains, significantly suppresses fusion, d) pseudoviruses produced in HLA-C silenced 293T cells display a significant reduction of infectivity; e) the fusion enhancement property of HLA-C is specific for HIV-1 Env, since a virus pseudotyped with the G envelope protein of VSV is not influenced by the presence of HLA-C.. The effect of HLA-C on fusion was ...

Bone Marrow Cells Differentiate in Cardiac Cell Lineages After Infarction Independently of Cell Fusion | Circulation Research
The current results are consistent with previous observations made in our laboratory3,19,20 in which an enriched population of c-kit-positive BMCs regenerated the infarcted myocardium. Similarly, BMCs and endothelial progenitor cells improve cardiac function in humans.4,6-12 So far, only one negative study has been reported.5 Moreover, a variety of bone marrow-derived cells capable of differentiating into the cardiac myogenic lineage have been described.3,10,17,18,20,29,30 It is therefore, difficult to reconcile our findings and the clinical and experimental studies with the claim made recently.13,14 The most likely possibility is a technical difference in the experimental protocol, identity of the therapeutic cell(s), tissue preparation, and immunocytochemical analysis of the myocardium.. The utilization of frozen tissue samples13,14 has severe limitations in terms of the quality of the sections, immunolabeling, and microscopic resolution. The infarct is rarely preserved in frozen sections. ...

If there is any sort of financial, climatic and/or conflict-based interruptions to the industrial infrastructure, I have to wonder whether that will be a very sudden end to what we think of as a modern life, because it just doesnt seem possible to me to re-manufacture, e.g., an oil-rig without an initial input of energy to do it, and without the oil-rigs wed not be able to drill down 5 miles under the sea where the oil is these days. It was easy when humans started down this route of burning fossil fuels because the stuff was just laying there in pools on the surface! Imagine that over again, and we didnt have that to start with.

Alternative splicing (the process during gene expression that generates multiple proteins from a single gene) plays an important role in many developmental processes.

Nuclear fusion is when the nuclei of a pair or more of atoms become fused together. The fusion of the atoms releases large amounts of energy. Nuclear fusion is what powers stars in space and has also been achieved within a human laboratory. While nuclear fusion could hypothetically be used as a source of terrestrial power, this has proven to be quite difficult. Surrounding each atom is a positively charged field known as the electrostatic force that tends to repel other atoms away before a pair of atoms can become close enough for their nuclei to fuse. It requires massive amounts of energy to overcome the repulsion of the electrostatic forces between neighboring atoms. Although the development of a nuclear fusion reactor has been a high priority for many governments around the world for many decades, nuclear fusion reactions being carried out in a laboratory have yet to result in a sustainable fusion chain reaction as it seems to require more energy to cause atoms to fuse than what is actually ...

I had a spinal fusion from T10 - S1 in 2010, the first time both of my rods broke was 5 years later (2015) and my surgeon did a repair. Three weeks ago (January 2019) one of the rods broke again. My surgeon cant figure out why they keep breaking. He said a contributing factor may be that they got my spine "ridiculously straight" which would add more pressure to the rods. He wants me to wait 2 months for the inflammation to go down, do a ct scan and then go back to him so we can figure out whether he is going to do another repair or replace all the hardware. Has anyone had anything similar happen?. ...

Harrelson plays a middle-aged loner curmudgeon in a comedy based on a graphic novel by Daniel Clowes, the creator of Ghost World.
In vivo corneal replicas were made in 20 cases of patients with superficial dendritic ulcers of the cornea. Histopathological study of the replicas and superficial epithelial cells showed that the dendrites are composed of rounded epithelial cells and variable sized syncytia containing bizarre shaped nuclei. Pseudopodia-like processes containing DNA and some RNA extend from the syncytia into the surrounding epithelial cells, which on coming into contact with these processes become rounded and liquefied to give rise to another syncytium. The epithelial cells adjacent to the dendrite and elongated and usually orientated parallel to the long axis of the lesion. Surrounding the terminal bulbs, they are disposed in an arcuate fashion. These cells show C-mitotic lesions, intranuclear and cytoplasmic inclusion bodies, and polykaryocyte formation. Microscopic examination of the corneal replicas shows the intranuclear lesions and rounding of cells up to about 2 mm away from the dendritic ulcers. These ...

Ultrastructure of the fusion cell in Faucheocolax attenuata Setch. (Rhodophyta, Rhodymeniales) | Journal of Cell Science
The fusion cell in Faucheocolax attenuata Setch. is a highly lobed, thick-walled, multinucleate and irregularly shaped cell originating from the basal cell of the auxiliary cell branch. The formation of the fusion cell occurs by an incorporation of vegetative cells into the basal cell, after dissolution of septal plugs between these cell types. Thus the fusion cell is a syncytium containing only haploid nuclei, as well as unusual mitochondria and plastids. Mitochondria lack cristae and instead contain a tubular helical structure. Plastids are atypical with regard to thylakoid organization in red algae, because they lack the peripheral thylakoid and their photosynthetic thylakoids are aggregated to one side. In addition, they contain large osmiophilic bodies. Nuclear envelopes appear to produce large quantities of membrane cisternae. Floridean starch is absent and the cytoplasm contains few ribosomes. The plasma membrane is irregular and endoplasmic reticulum cisternae are situated parallel to ...

AU - Winey, Mark. AU - Turkewitz, Aaron P.. PY - 2005/4/1. Y1 - 2005/4/1. N2 - The formation of dense core secretory granules is a multi-stage process beginning in the trans Golgi network and continuing during a period of granule maturation. Direct interactions between proteins in the membrane and those in the forming dense core may be important for sorting during this process, as well as for organizing membrane proteins in mature granules. We have isolated two mutants in dense core granule formation in the ciliate Tetrahymena thermophila, an organism in which this pathway is genetically accessible. The mutants lie in two distinct genes but have similar phenotypes, marked by accumulation of a set of granule cargo markers in intracellular vesicles resembling immature secretory granules. Sorting to ...

Biological Characterization of the Virus Causing Leukoencephalitis and Arthritis in Goats | Microbiology Society
Summary This study describes the biological properties of a strain of virus isolated from tissues of a goat with leukoencephalomyelitis-arthritis. The agent is a retrovirus, having a virion-associated reverse transcriptase enzyme and an antigenic determinant(s) which cross-reacts with the p30 of visna-maedi viruses. Morphogenesis of the virus is also similar to visna virus in terms of virus assembly and the multinucleated giant cell formation which accompanies replication of the latter virus. Despite its cytopathogenic property the goat agent was not lytic in goat cell culture, causing instead a productive infection which persisted through multiple subcultures of the cells. The virus replicated incompletely in sheep cell cultures but could be rescued from the latter, weeks after inoculation, by co-cultivation with goat cells. Our data suggest that this strain of goat leukoencephalitis virus is a variant of the ovine retroviruses with a host range limited to the goat.
DC-STAMP was identified from a screening of human monocyte cDNA libraries (17) as a putative seven-transmembrane-spanning receptor with no homology to any other known protein or multimembrane-spanning receptor. DC-STAMP is expressed both in immature and mature dendritic cells (DCs), and its mRNA levels fall upon activation of DCs with CD40 ligand (CD40L). DC-STAMP is overexpressed in giant cell tumors together with receptor activator of NF-κB ligand (RANKL), a protein required for the development of osteoclasts (18). In a recent study, Kukita et al. showed, using small interfering RNAs and specific antibodies, that DC-STAMP is essential for osteoclastogenesis in mice (2). They reported that overexpression of DC-STAMP enhanced osteoclastogenesis and induced the expression of a marker of osteoclasts, tartrate-resistant acid phosphatase. In this issue, Yagi et al. (1) used gene targeting to demonstrate that DC-STAMP is also essential for the fusion of osteoclast precursor cells and macrophages. ...
Maedi visna virus (MVV) is a retrovirus that is member of the Lentivirus genus. MVV infects sheep and goats and causes progressive pneumonia or paralysis, leading to death. Since the discovery of the receptor for Human immunodeficiency virus (HIV), Simian immunodeficiency virus (SIV) and Feline immunodeficiency virus (FIV) all include the chemokine receptor CXCR4, it has been postulated that all members of the Lentivirus share a common mechanism of entry that involves the use of CXCR4. With the use of syncytia assays, infection-, inhibition- and enhancement studies, it was shown that CXCR4 is not a common lentivirus receptor. U87 and HOS cells, both celllines lacking CXCR4, were susceptible to infection. However, cells transfected with CD4 and CXCR4 showed an increased syncytia formation and the presence of CD¤ and CXCR4 augments virus-induced cell fusion. The nature of MVV receptor is still not known, but our data suggest the use of CD4 and/or CXCR4 as accessory molecules or as part of a ...
