Pro-apoptotic anti-NG2/CSPG4 monoclonal antibodies for disease therapy
No full textA first aspect of the present invention refers to an antibody, preferably a monoclonal
antibody, recognizing the extracellular domain of NG2/CSPG4 and its ability to induce
apoptosis and/or autophagy upon antigen-binding in cancer cells expressing
NG2/CSPG4.
10 Therefore, the antibody of the invention can be used for cell growth inhibition by
exposing a cell expressing NG2/CSPG4 to a therapeutic amount of an antibody capable
of binding to NG2/CSPG4.
A second aspect of the present invention refers to a pharmacological composition
comprising a therapeutic amount of the antibody, in its entirety or single chain variable
15 fragment (scFv) of the invention that is active against NG2/CSPG4, or any other portion
of the antibody, preferably, embodied in a bispecific antibody construct (e.g. an antibody
binding both NG2/CSPG4 and another cell surface molecule and/or antigen) or a fusion
protein comprised of a therapeutic amount of the antibody, in its entirety or single chain
variable fragment, or scFv, an another therapeutic molecule, such as a cytochine or an
20 aptoptosis-inducing agent (e.g TRAIL or Fas Ligand), or a CAR T (Chimeric Antigen
Receptor T cell) construct in which the scFv derived from the portion of the antibody of
the invention is expressed on the surface of a CAR T cell, such as to simultaneously
engaging NG2/CSPG4 expressing cells and endogenous T cells and favor the
maintenance of the CAR T cell in proximity to the cancer cell to trigger the activation of
25 the engaged T cell.
Further provided by the invention is the use of the antibody and the composition of the
invention for selective trigger of apoptosis and/or autophagy in cells specifically
expressing NG2/CSPG4 recognized by the antibody.
A further aspect of present invention refers to the antibody and the composition of the
30 invention for use in the treatment of an apoptosis and/or autophagy-dependent disease,
preferably cancer, more preferably solid or hematological cancers, as well as cancerrelated
diseases
Pro-apoptotic anti-NG2/CSPG4 antibodies and their uses for disease therapy
No full textThe present invention relates to an antibody capable of binding with high-affinity and high selectivity to the ectodomain of the transmembrane proteoglycan (PG) NG2/CSPG4, preferably to discrete isoforms of NG2/CSPG4. The invention further relates to said antibody possessing the ability to uniquely induce programmed cell death, exhibited as both canonical caspase-dependent apoptosis and authophagy, in NG2/CSPG4-expressing cancer cells. This action being manifested irrespectively of the coaction of other exogenously added factors.
Moreover, the present invention refers to a composition comprising the antibody of the invention, in their naked, encapsulated or genetically engineered form, as pharmaceutical excipients.
A further aspect of the present invention refers to the anti-NG2/CSPG4 molecule, or any of its isoforms and fragments, provided as proteolytically generated peptides or produced synthetically and/or recombinantly, for the treatment of apoptosis and/or autophagy-dependent diseases, including but not restricted to cancer
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
