Immunoglobulin Light Chains
Immunoglobulin Heavy Chains
Immunoglobulin Fab Fragments
Univalent antigen-binding fragments composed of one entire IMMUNOGLOBULIN LIGHT CHAIN and the amino terminal end of one of the IMMUNOGLOBULIN HEAVY CHAINS from the hinge region, linked to each other by disulfide bonds. Fab contains the IMMUNOGLOBULIN VARIABLE REGIONS, which are part of the antigen-binding site, and the first IMMUNOGLOBULIN CONSTANT REGIONS. This fragment can be obtained by digestion of immunoglobulins with the proteolytic enzyme PAPAIN.
A microtubule subunit protein found in large quantities in mammalian brain. It has also been isolated from SPERM FLAGELLUM; CILIA; and other sources. Structurally, the protein is a dimer with a molecular weight of approximately 120,000 and a sedimentation coefficient of 5.8S. It binds to COLCHICINE; VINCRISTINE; and VINBLASTINE.
Immunoglobulin A, Secretory

Platelet Glycoprotein GPIIb-IIIa Complex
Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. It is an integrin complex containing INTEGRIN ALPHAIIB and INTEGRIN BETA3 which recognizes the arginine-glycine-aspartic acid (RGD) sequence present on several adhesive proteins. As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.
Clinical Trials, Phase IV as Topic
Planned post-marketing studies of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques that have been approved for general sale. These studies are often conducted to obtain additional data about the safety and efficacy of a product. This concept includes phase IV studies conducted in both the U.S. and in other countries.
Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.
Antibodies, Monoclonal, Humanized
Antibodies from non-human species whose protein sequences have been modified to make them nearly identical with human antibodies. If the constant region and part of the variable region are replaced, they are called humanized. If only the constant region is modified they are called chimeric. INN names for humanized antibodies end in -zumab.
A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.
Removal of toxins or metabolites from the circulation by the passing of blood, within a suitable extracorporeal circuit, over semipermeable microcapsules containing adsorbents (e.g., activated charcoal) or enzymes, other enzyme preparations (e.g., gel-entrapped microsomes, membrane-free enzymes bound to artificial carriers), or other adsorbents (e.g., various resins, albumin-conjugated agarose).
Tumor Necrosis Factor-alpha
Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.
A polysaccharide with glucose units linked as in CELLOBIOSE. It is the chief constituent of plant fibers, cotton being the purest natural form of the substance. As a raw material, it forms the basis for many derivatives used in chromatography, ion exchange materials, explosives manufacturing, and pharmaceutical preparations.
Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
Vitamin B 12
A cobalt-containing coordination compound produced by intestinal micro-organisms and found also in soil and water. Higher plants do not concentrate vitamin B 12 from the soil and so are a poor source of the substance as compared with animal tissues. INTRINSIC FACTOR is important for the assimilation of vitamin B 12.
Orphan Drug Production
The collective designation of three organizations with common membership: the European Economic Community (Common Market), the European Coal and Steel Community, and the European Atomic Energy Community (Euratom). It was known as the European Community until 1994. It is primarily an economic union with the principal objectives of free movement of goods, capital, and labor. Professional services, social, medical and paramedical, are subsumed under labor. The constituent countries are Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, and the United Kingdom.

Interaction of inflammatory cells and oral microorganisms. III. Modulation of rabbit polymorphonuclear leukocyte hydrolase release response to Actinomyces viscosus and Streptococcus mutans by immunoglobulins and complement. (1/2903)In the absence of antiserum, rabbit polymorphonuclear leukocytes (PMNs) released lysosomal enzymes in response to Actinomyces viscosus (19246) but not to Streptococcus mutans (6715). Antibodies had a marked modulating influence on these reactions. PMN hydrolase release was significantly enhanced to both organisms when specific rabbit antiserum and isolated immunoglobulin G (IgG) were included in the incubations. Immune complex F(ab')2 fragments of IgG directed against S. mutans agglutinated bacteria. Immune complexes consisting of S. mutans and F(ab')2 fragments of IgG directed against this organism were not effective as bacteria-IgG complexes in stimulating PMN release. The intensity of the release response to bacteria-IgG complexes was also diminished when PMNs were preincubated with isolated Fc fragments derived from IgG. Fresh serum as a source of complement components had no demonstrable effect on PMN release either alone or in conjuction with antiserum in these experiments. These data may be relevant to the mechanisms and consequences of the interaction of PMNs and plaque bacteria in the pathogenesis of periodontal disease. (+info)
Labeling of the internal pool of GP IIb-IIIa in platelets by c7E3 Fab fragments (abciximab): flow and endocytic mechanisms contribute to the transport. (2/2903)Abciximab is a new antiplatelet therapeutic in ischemic cardiovascular disease. The drug, chimeric Fab fragments of a murine monoclonal antibody (MoAb) (c7E3), blocks GP IIb-IIIa function. However, its capacity to reach all receptor pools in platelets is unknown. Electron microscopy and immunogold labeling were used to localize abciximab in platelets of patients receiving the drug for up to 24 hours. Studies on frozen-thin sections showed that c7E3 Fab, in addition to the surface pool, also labeled the surface-connected canalicular system (SCCS) and alpha-granules. Analysis of gold particle distribution showed that intraplatelet labeling was not accumulative and in equilibrium with the surface pool. After short-term incubations of platelets with c7E3 Fab in vitro, gold particles were often seen in lines within thin elements of the SCCS, some of which appeared in contact with alpha-granules. Little labeling was associated with Glanzmann's thrombasthenia platelets, confirming that the channels contained bound and not free c7E3 Fab. Endocytosis of abciximab in clathrin-containing vesicles was visualized by double staining and constitutes an alternative mechanism of transport. The remaining free pool of GP IIb-IIIa was evaluated with the MoAb AP-2; flow cytometry showed it to be about 9% on the surface of nonstimulated platelets but 33% on thrombin-activated platelets. The ability of drugs to block all pools of GP IIb-IIIa and then to be associated with secretion-dependent residual aggregation must be considered when evaluating their efficiency in a clinical context.

Recognition of polynucleotides by antibodies to poly(I), poly(C). (3/2903)The binding of anti poly(I). poly (C) Fab fragments to double or triple stranded polynucletides has been studied by fluorescence. Association constants were deduced from competition experiments. The comparison of the association constants leads to the conclusion that several atoms of the base residues do not interact with the amino acid residues of the binding site of Fab fragment while the hydroxyl groups of furanose rings interact. These results suggest that the Fab fragments do not bind to the major groove of the double stranded polynucleotides. An interaction between the C(2)O group of pyrimidine residues and Fab fragments cannot be excluded. Circular dichroism of poly(I). poly(C) or poly(I). poly(br5C)-Fab fragments complexes are very different from the circular dichroism of free polynucleotides which suggests a deformation of the polynucleotides bound to the Fab fragments.

Efficient IgG-mediated suppression of primary antibody responses in Fcgamma receptor-deficient mice. (4/2903)IgG antibodies can suppress more than 99% of the antibody response against the antigen to which they bind. This is used clinically to prevent rhesus-negative (Rh-) women from becoming immunized against Rh+ erythrocytes from their fetuses. The suppressive mechanism is poorly understood, but it has been proposed that IgG/erythrocyte complexes bind to the inhibitory Fc receptor for IgG (FcgammaRIIB) on the B cell surface, thereby triggering negative signals that turn off the B cell. We show that IgG induces the same degree of suppression of the response to sheep erythrocytes in animals lacking the known IgG-binding receptors FcgammaRIIB, FcgammaRI + III, FcgammaRI + IIB + III, and FcRn (the neonatal Fc receptor) as in wild-type animals. Reinvestigation of the ability of F(ab')2 fragments to suppress antibody responses demonstrated that they were nearly as efficient as intact IgG. In addition, monoclonal IgE also was shown to be suppressive. These findings suggest that IgG inhibits antibody responses through Fc-independent mechanisms, most likely by masking of antigenic epitopes, thereby preventing B cells from binding and responding to antigen. In agreement with this, we show that T cell priming is not abolished by passively administered IgG. The results have implications for the understanding of in vivo regulation of antibody responses and Rh prophylaxis. (+info)
Head-to-tail dimers and interdomain flexibility revealed by the crystal structure of HIV-1 capsid protein (p24) complexed with a monoclonal antibody Fab. (5/2903)The crystal structure of an intact molecule of HIV-1 capsid protein (p24) in complex with a monoclonal antibody fragment recognizing an epitope on the C-terminal domain has been determined at 3 A resolution. The helical N- and C-terminal domains of p24 are linked by an extended peptide forming a flexibly linked dumb-bell-shaped molecule 75 A in overall length. The p24 construct used is a variant with an N-terminal extension that mimics to some extent the Gag context of p24. We observed a novel head-to-tail dimer of p24 molecules which occurs through the formation of a substantial intermolecular interface between the N- and C-terminal domains. Comparison with previously observed p24 dimers shows that the same residues and secondary structural elements can partake in different interfaces revealing a remarkable stickiness and plasticity of the p24 molecule, properties which, combined with the inter-domain flexibility, are presumably important in the assembly and maturation of viral particles. Previous mutagenesis studies designed to test specific N-N and C-C homodimer interfaces do not discriminate fully against the possibility of the observed N-C interface. (+info)
Flexibility of the major antigenic loop of foot-and-mouth disease virus bound to a Fab fragment of a neutralising antibody: structure and neutralisation. (6/2903)The interaction of foot-and-mouth disease virus (FMDV) serotype C (clone C-S8c1) with a strongly neutralising monoclonal antibody (MAb) 4C4 has been studied by combining data from cryoelectron microscopy and x-ray crystallography. The MAb 4C4 binds to the exposed flexible GH-loop of viral protein 1 (VP1), which appears to retain its flexibility, allowing movement of the bound Fab. This is in striking contrast to MAb SD6, which binds to the same GH-loop of VP1 but exhibits no movement of the bound Fab when observed under identical conditions. However, MAbs 4C4 and SD6 have very similar neutralisation characteristics. The known atomic structure of FMDV C-S8c1 and that of the 4C4 Fab cocrystallised with a synthetic peptide corresponding to the GH-loop of VP1 were fitted to the cryoelectron microscope density map. The best fit of the 4C4 Fab is compatible only with monovalent binding of the MAb in agreement with the neutralisation data on 4C4 MAbs, Fab2s, and Fabs. The position of the bound GH-loop is related to other known positions of this loop by a hinge rotation about the base of the loop. The 4C4 Fab appears to interact almost exclusively with the G-H loop of VP1, making no other contacts with the viral capsid. (+info)
Analysis of the interaction of monoclonal antibodies with surface IgM on neoplastic B-cells. (7/2903)In vitro studies identified three Burkitts lymphoma cell lines, Ramos, MUTU-I and Daudi, that were growth inhibited by anti-IgM antibody. However, only Ramos and MUTU-I were sensitive to monoclonal antibodies (mAb) recognizing the Fc region of surface IgM (anti-Fc mu). Experiments using anti-Fc mu mAb (single or non-crossblocking pairs), polyclonal anti-mu Ab, and hyper-crosslinking with a secondary layer of Ab, showed that growth inhibition of B-cell lines was highly dependent on the extent of IgM crosslinking. This was confirmed by using Fab', F(ab')2 and F(ab')3 derivatives from anti-Fc mu mAb, where increasing valency caused corresponding increases in growth arrest and apoptosis, presumably as a result of more efficient BCR-crosslinking on the cell surface. The ability of a single mAb to induce growth arrest was highly dependent on epitope specificity, with mAb specific for the Fc region (C mu2-C mu4 domains) being much more effective than those recognizing the Fab region (anti-L chain, anti-Id and anti-Fd mu, or C mu1). Only when hyper-crosslinked with polyclonal anti-mouse IgG did the latter result in appreciable growth inhibition. Binding studies showed that these differences in function were not related to differences in the affinity, but probably related to intrinsic crosslinking capacity of mAb. (+info)
Structural details of proteinase entrapment by human alpha2-macroglobulin emerge from three-dimensional reconstructions of Fab labeled native, half-transformed, and transformed molecules. (8/2903)Three-dimensional electron microscopy reconstructions of native, half-transformed, and transformed alpha2-macroglobulins (alpha2Ms) labeled with a monoclonal Fab Fab offer new insight into the mechanism of its proteinase entrapment. Each alpha2M binds four Fabs, two at either end of its dimeric protomers approximately 145 A apart. In the native structure, the epitopes are near the base of its two chisel-like features, laterally separated by 120 A, whereas in the methylamine-transformed alpha2M, the epitopes are at the base of its four arms, laterally separated by 160 A. Upon thiol ester cleavage, the chisels on the native alpha2M appear to split with a separation and rotation to give the four arm-like extensions on transformed alpha2M. Thus, the receptor binding domains previously enclosed within the chisels are exposed. The labeled structures further indicate that the two protomeric strands that constitute the native and transformed molecules are related and reside one on each side of the major axes of these structures. The half-transformed structure shows that the two Fabs at one end of the molecule have an arrangement similar to those on the native alpha2M, whereas on its transformed end, they have rotated. The rotation is associated with a partial untwisting of the strands and an enlargement of the openings to the cavity. We propose that the enlarged openings permit the entrance of the proteinase. Then cleavage of the remaining bait domains by a second proteinase occurs with its entrance into the cavity. This is followed by a retwisting of the strands to encapsulate the proteinases and expose the receptor binding domains associated with the transformed alpha2M. (+info)
Early abciximab administration before transfer for primary percutaneous coronary interventions for ST-elevation myocardial...
Background There are conflicting data on the clinical benefit from early administration of abciximab from a large randomized trial and a registry. However, both sources suggest that a benefit may depend on the baseline risk profile of the patients. We evaluated the role of early abciximab administration in patients with ST-segment-elevation myocardial infarction (STEMI) referred for primary percutaneous coronary intervention stratified by the STEMI Thrombolysis In Myocardial Infarction (TIMI) risk score. Methods A total of 1,650 patients were enrolled into the EUROTRANSFER Registry. One thousand eighty-six patients received abciximab (66%). Abciximab was administered early in 727 patients (EA) and late in 359 patients (LA). We used the TIMI risk score for risk stratification. Patients with scores 3 constituted the high-risk group of 616 patients (56.7%), whereas 470 patients formed the low-risk cohort. Factoring in the timing of the abciximab administration resulted in 4 groups of patients who ...
Recognition properties of a panel of human recombinant Fab fragments to the CD4 binding site of gp120 that show differing...
Six recombinant human Fab fragments that were derived from the same human immunodeficiency virus type 1 (HIV-1)-infected individual and are directed against the CD4 binding site (CD4bs) of the gp120 envelope glycoprotein were studied. A range of neutralizing activity against the HIV-1 (HXBc2) isolate was observed, with Fab b12 exhibiting the greatest potency among the Fabs tested. The neutralizing potency of Fab b12 was better than that of monoclonal whole antibodies directed against the third variable (V3) region of gp120. To explore the basis for the efficient neutralizing activity of b12, the recognition of a panel of HIV-1 gp120 mutants by the six Fabs was studied. The patterns of sensitivity to particular gp120 amino acid changes were similar for all six Fabs to those seen for anti-CD4bs monoclonal antibodies derived from HIV-1-infected individuals by conventional means. In addition, recognition by Fab b12 demonstrated an atypical sensitivity to changes in the V1 and V2 variable regions. ...

Clinical and demographic characteristics predictive of treatment outcomes for certolizumab pegol in moderate to severe Crohns...
These analyses identified several influential parameters for short-and long-term remission of Crohns disease with certolizumab pegol treatment. The data yield valuable hypotheses regarding factors that influence certolizumab pegol treatment. More investigation is needed. (ClinicalTrials.gov identifier NCT00552058).Predictors for initial remission (N = 377) included age, haematocrit, prior IBD surgery and entry HBI (P , 0.05 for all). Predictors for loss of remission (N = 437) included HBI, serum albumin concentration, haematocrit, smoking status and exposure. Predictors of maintenance of remission (N = 437) included haematocrit, IBD surgery, HBI, disease duration, serum albumin concentration and exposure. Significant predictors were confirmed with stepwise multivariate regression models.Patients who had completed placebo-controlled studies (PRECiSE 1/PRECiSE 2, P1/P2) enrolled in P3 and received open-label CZP 400 mg every 4 weeks up to 7 years.

Certolizumab pegol for the treatment of Crohns disease. | IKMB
In patients with moderate-to-severe Crohns disease, induction and maintenance therapy with certolizumab pegol was associated with a modest improvement in response rates, as compared with placebo, but with no significant improvement in remission rates. (ClinicalTrials.gov number, NCT00152490 [ClinicalTrials.gov].).Among patients with a baseline CRP level of at least 10 mg per liter, 37% of patients in the certolizumab group had a response at week 6, as compared with 26% in the placebo group (P=0.04). At both weeks 6 and 26, the corresponding values were 22% and 12%, respectively (P=0.05). In the overall population, response rates at week 6 were 35% in the certolizumab group and 27% in the placebo group (P=0.02); at both weeks 6 and 26, the response rates were 23% and 16%, respectively (P=0.02). At weeks 6 and 26, the rates of remission in the two groups did not differ significantly (P=0.17). Serious adverse events were reported in 10% of patients in the certolizumab group and 7% of those in the ...
Human-Derived Anti-Oxidized LDL Autoantibody Blocks Uptake of Oxidized LDL by Macrophages and Localizes to Atherosclerotic...
To understand the potential role(s) that autoantibodies to OxLDL play in atherogenesis in humans, we isolated several human monoclonal IgG Fab antibodies that bound to epitopes of OxLDL, initially focusing on MDA-LDL, a model epitope of OxLDL. To our knowledge, these are the first human monoclonal antibodies against oxidation-specific epitopes of OxLDL to be characterized. All 3 Fab antibodies showed distinct antigen-binding specificity to MDA-LDL compared with other unrelated antigens. To isolate these antibodies, we used a phage display combinatorial library technique that enables rapid enrichment of desired Fab clones by using antigen-coated surfaces.10 This technique has been used to isolate monoclonal Fab antibodies from immunized animals and to study pathogenic autoantibodies in various human autoimmune disorders.23-25 Although it is not feasible to directly compare hybridomas and combinatorial libraries, several studies have demonstrated that repertoires cloned from phage display ...
Cap formation - Wikipedia
When molecules on the surface of cell are crosslinked, they are moved to one end of the cell to form a cap. This phenomenon, the process of which is called cap formation, was discovered in 1971 on lymphocytes and is a property of amoebae and all locomotory animal cells except sperm. The crosslinking is most easily achieved using a polyvalent antibody to a surface antigen on the cell. Cap formation can be visualised by attaching a fluorophore, such as fluorescein, to the antibody. The antibody is bound to the cell. If the antibody is non-crosslinking (such as a Fab antibody fragment), the bound antibody is uniformly distributed. This can be done at 0 °C, room temperature, or 37 °C. If the antibody is crosslinking and bound to the cells at 0 °C, the distribution of antibodies has a patchy appearance. These patches are two-dimensional precipitates of antigen-antibody complex and are quite analogous to the three-dimensional precipitates that form in solution. If cells with patches are warmed ...

Induction of cell-cell adhesion by monovalent antibodies in a germ cell culture | Development
Four monoclonal antibodies, XT-I, MT-23, MT-24 and MT-29, that bind the XT-1-differentiation-antigen of male germ cells have been used to investigate the biological role of the XT-1-molecule of germ cells in short-term primary culture. Cultures from 10 days postpartum mice demonstrate increasing numbers of antigen-positive germ cells and increased antigen expression per cell with succeeding days of culture. Treatment of the antigen-positive cultures with three of the monoclonal antibodies, XT-I, MT-23 and MT-24, increases germ cell-germ cell adhesion in a dose-dependent fashion. Treatment with the fourth monoclonal antibody, MT-29, does not induce cell adhesion. The monovalent, Fab fragment of XT-I-antibody also elicits tight cell adhesion, thus ruling out antibody cross linking of molecules or cells. Saturating or near saturating amounts of the positive antibodies are required to produce adhesion, a result consistent with perturbation of a function that is performed by the sum of action of many ...

Human IgG F(ab)2 Antibody 209-1104
Anti-Human IgG F(ab)2 Antibody generated in goat recognizes the dimeric Fab portion of the human IgG molecule. Human IgG F(ab)2 is a proteolytic fragment of immunoglobulin G (IgG) obtained by limited digestion with the enzyme pepsin under controlled conditions of temperature, time and pH. F(ab)2 molecules lack the Fc portion of IgG and therefore receptors that bind human IgG F(c) will not bind human IgG F(ab)2 molecules. Secondary Antibodies are available in a variety of formats and conjugate types. When choosing a secondary antibody product, consideration must be given to species and immunoglobulin specificity, conjugate type, fragment and chain specificity, level of cross-reactivity, and host-species source and fragment composition.

Physical and Functional Bivalency Observed Among TCR/CD3 Complexes Isolated from Primary T Cells | The Journal of Immunology
Although we have shown that bivalent TCR/CD3 are present among digitonin-solubilized complexes, we do not know the proportion of complexes that they represent. One focus of future experiments must be to develop other methods that would permit a quantitative estimate of the prevalence of bivalency among all TCR/CD3 complexes. However, despite this current technical limitation, the data in Fig. 7 imply that the proportion of bivalent complexes is sufficiently high to impact the outcome of the pMHC-Ig fusion protein binding assay performed. Thus, based on the assumption that this assay reflects a true potential for functional impact, we speculate that it is likely that a biologically significant number of TCR/CD3 complexes display bivalency.. It is not known which motifs might specifically interact to compose a bivalent complex. Even in the standard monovalent model of TCR/CD3, the interactions between subunit dimers (αβ/εγ/εδ/ζζ) that compose the multiprotein complex are not fully ...

A novel LFA-1 activation epitope maps to the I domain. | Journal of Cell Biology | Rockefeller University Press
A panel of 21 alpha-subunit (CD11a) and 10 beta-subunit (CD18) anti-LFA-1 mAbs was screened for ability to activate LFA-1. A single anti-CD11a mAb, MEM-83, was identified which was able to directly induce the binding of T cells to purified ICAM-1 immobilized on plastic. This ICAM-1 binding could be achieved by monovalent Fab fragments of mAb MEM-83 at concentrations equivalent to whole antibody, was associated with appearance of the activation reporter epitope detected by mAb 24, and was completely inhibited by anti-ICAM-1 and LFA-1 blocking mAbs. The epitope recognized by mAb MEM-83 was distinct from that recognized by mAb NKI-L16, an anti-CD11a mAb previously reported to induce LFA-1 activation, in that it was constitutively present on freshly isolated peripheral blood mononuclear cells and was not divalent cation dependent for expression. The ICAM-1 binding activity induced by mAb MEM-83 was, however, dependent on the presence of Mg2+ divalent cations. Using an in vitro-translated CD11a ...

Chemical Biology Seminar | Caltech
Due to their specificity and favorable pharmacological properties, monoclonal antibodies (mAbs) are being rapidly developed and armed to image and treat disease. Invariably, chemical methods and/or extensive genetic engineering efforts are required to add novel functionality to mAbs. Through diffraction methods, we have identified a novel peptide interface within a cavity formed by the light and heavy chains of the cetuximab Fab that may provide an entirely novel, noncovalent route to functionalize and/or manipulate mAbs. Distinct from other Fab binding proteins such as protein A or protein L, we show that this peptide interaction is exclusive to cetuximab. In other words, the peptide binding site absent in human mAbs. Moreover, we demonstrate that the presence of the peptide (which we have named a meditope) does not affect antigen binding. Anticipating that this non-covalent method could be used to direct an imaging agent to a tumor cell, we created a bivalent meditope analog and show that this ...
Intracoronary Thrombus and Platelet Glycoprotein IIb/IIIa Receptor Blockade With Tirofiban in Unstable Angina or Non-Q-Wave...
This angiographic study in PRISM-PLUS was the first to examine the effects of platelet GP IIb/IIIa receptor blockade on the culprit lesion in patients with UA or NQWMI. It was also the largest prospective study that examined the angiographic characteristics of culprit lesions and their prognostic significance. The study demonstrated that the combination of tirofiban, heparin, and aspirin significantly reduced the thrombus burden of the culprit lesion by 23% beyond the effects of heparin and aspirin, resulting in decreased coronary obstruction and improved distal flow. These data are consistent with the 32% reduction in risk of death, MI, or RI observed at 7 days with the combination therapy and with the 43% reduction in the risk of death or MI. The present study also provided evidence that persistence of an angiographic thrombus after a course of medical therapy is an indicator of a worse prognosis, which suggests important pathophysiological concepts and therapeutic implications..

Evidence for Prevention of Death and Myocardial Infarction With Platelet Membrane Glycoprotein IIb/IIIa Receptor Blockade by...
Despite considerable research into pharmacologic and revascularization treatments for the acute coronary ischemic syndromes, outcome among patients hospitalized with unstable angina remains unsatisfactory. Recently reported large-scale randomized trials, for example, have demonstrated that the risk of death or MI within the first 4 to 6 weeks after development of unstable angina is as high as 9% to 11% ([27, 28]). Although percutaneous myocardial revascularization has been advocated as a means of reducing morbidity in this group of patients, particularly those with symptoms refractory to medical therapy (), several studies have suggested that patients undergoing a coronary intervention in the setting of unstable angina are at elevated risk for ischemic complications compared with patients treated by revascularization for more stable indications ([5-8]).. The current study evaluated clinical outcome in the subgroup of 489 patients who met rigorous criteria for unstable angina in the ...

جامعة الأندلس الخاصة للعلوم الطبية - Cimzia (Certolizumab Pegol Injection)
Patients were tested at multiple time points for antibodies to certolizumab pegol during Studies CD1 and CD2. The overall percentage of antibody positive patients was 8% in patients continuously exposed to CIMZIA, approximately 6% were neutralizing in vitro. No apparent correlation of antibody development to adverse events or efficacy was observed. Patients treated with concomitant immunosuppressants had a lower rate of antibody development than patients not taking immunosuppressants at baseline (3% and 11%, respectively). The following adverse events were reported in Crohns disease patients who were antibody-positive (N = 100) at an incidence at least 3% higher compared to antibody-negative patients (N = 1,242): abdominal pain, arthralgia, edema peripheral, erythema nodosum, injection site erythema, injection site pain, pain in extremity, and upper respiratory tract infection..

High frequency of antidrug antibodies and association of random drug levels with efficacy in certolizumab pegol-treated...
This study demonstrates for the first time that certolizumab ADAbs were detectable in 37% of patients with RA over 12 months of treatment. Detectable ADAbs were associated with lower certolizumab drug concentrations, but not independently with treatment response. However, higher certolizumab drug levels were associated with better 12 months EULAR response. Following adjustment, ADAb concentrations and biologic adherence remained the most important predictors of drug levels over time.. Our data demonstrates that even small, non-glycosylated fragments such as certolizumab can be immunogenic. The higher levels of ADAbs detected compared with previous certolizumab trials1 ,2 is noteworthy. However, in contrast to other biologics, ADAbs against certolizumab may be detected more easily even in the presence of drug. Certolizumab is a Fab fragment, monovalent, and therefore, drug-ADAb complexes easily dissociate and can thus be detected despite the drug not necessarily being more immunogenic. RIA, for ...

Real-life experience with the specific reversal agent idarucizumab for the management of emergency situations in dabigatran...
Non-vitamin K antagonist oral anticoagulants (NOACs) have a favorable benefit-risk profile compared with vitamin K antagonists. However, the lack of specific reversal agents has made the management of some patients receiving long-term treatment with NOACs problematic in emergency situations such as major bleeding events or urgent procedures. Idarucizumab, a fully humanized Fab antibody fragment that binds specifically and with high affinity to dabigatran, was recently approved for use in adult patients treated with dabigatran when rapid reversal of its anticoagulant effect is required. Clinical experience with idarucizumab is currently limited. We report 11 real-life clinical cases in which idarucizumab was used after multidisciplinary consultation in a variety of emergency situations including severe postoperative bleeding, emergency high-bleeding-risk surgery (hip/spine surgery and neurosurgery), invasive diagnostic testing (lumbar puncture), intracranial bleeding (pre-pontine subarachnoid ...

Engineering an Improved IgG4 Molecule with Reduced Disulfide Bond Heterogeneity and Increased Fab Domain Thermal Stability -...
The integrity of antibody structure, stability, and biophysical characterization are becoming increasingly important as antibodies receive increasing scrutiny from regulatory authorities. We altered the disulfide bond arrangement of an IgG4 molecule by mutation of the Cys at the N terminus of the heavy chain constant domain 1 (CH1) (Kabat position 127) to a Ser and introduction of a Cys at a variety of positions (positions 227-230) at the C terminus of CH1. An inter-LC-CH1 disulfide bond is thus formed, which mimics the disulfide bond arrangement found in an IgG1 molecule. The antibody species present in the supernatant following transient expression in Chinese hamster ovary cells were analyzed by immunoblot to investigate product homogeneity, and purified product was analyzed by a thermofluor assay to determine thermal stability. We show that the light chain can form an inter-LC-CH1 disulfide bond with a Cys when present at several positions on the upper hinge (positions 227-230) and that such ...

Complementarity determining region-independent recognition of a superantigen by B-cell antigen receptors of mantle cell...
This raised the question as to whether SpA might act as a superantigen, triggering activation of the BCR signaling pathway in a substantial proportion of MCL patients.. Therefore, we explored the interaction of SpA with lymphoma BCR-derived immunoglobulins harboring the SpA binding motif. Since SpA has a high affinity to the Fc domain of human IgG, representative MCL Igs were expressed as Fab fragments. Six different MCL- (with and without SpA binding motif), two CLL- and one FL-derived Fab fragments were produced and tested for SpA reactivity using an ELISA with coated SpA. In fact, all Fab fragments exhibiting the SpA binding motif bound to SpA in this assay, whereas Fab fragments without SpA binding motif were non-reactive (Figure 1B).. Having established that SpA binds to a substantial proportion of MCL-derived immunoglobulins in vitro, we next investigated whether this interaction is sufficient to activate the BCR signaling pathway in human B-cells expressing SpA-reactive MCL BCR. We ...

Antibody Deficiencies | The Online Metabolic and Molecular Bases of Inherited Disease | OMMBID | McGraw-Hill Medical
Antibodies are produced by plasma cells, the terminally differentiated descendants of the B-cell lineage. The early stages of B-cell development occur in the bone marrow, where pro-B cells, which are derived from hematopoietic stem cells, undergo rearrangement of the immunoglobulin heavy-chain genes. This process occurs throughout the life of the individual. At the next stage of B-cell differentiation, in pre-B cells, there is rearrangement of the light-chain genes. This allows the expression of the intact immunoglobulin molecule on the cell surface of the B cell. Each B cell and its progeny express only one rearranged immunoglobulin heavy chain and one light chain. When antigen binds to the surface of the B cell, if the appropriate environmental signals are received, the B cell proliferates and differentiates into a memory B cell that can respond more rapidly to future exposures to that antigen or to a plasma cell that secretes high concentrations of antibodies.. ...

Abstract P-45: Structural Studies of Multispecific Antibody/Antigen Complexes by Cryo-EM | International Journal of Biomedicine
Background: Multispecific antibodies are artificially engineered molecules designed to bind simultaneously to several (different) antigens. Potential advantages of generating viable multispecific antibodies include the identification of malignant cells coupled with the concurrent recruitment of immune cells and the blocking of complex viral escape mechanisms. The cross-over dual-variable immunoglobulin (CODV-Ig) has been proposed as a universal bispecific therapeutic format. Its unique antigen-binding fragment (Fab) architecture provides pM affinities for ligands, no positional effect in target binding and a stable self-supporting structure. However, the three-dimensional arrangement of the constant and antigen-binding fragments in the CODV-Ig format may play a role in its in vivo effects. To further understand the structure and function of multispecific antibodies based on the CODV-Ig format high-resolution structural information is required. Towards this, we use cryo-electron microscopy ...
