AB  - Gene as the basic functional unit of DNA encodes information about the product such as protein. The majority of proteins realize function through protein-protein interactions involving short protein motifs. However, some proteins such as antibodies are established by the rearrangement of several (V-D-J) gene segments with the potential addition of nontemplated nucleotides that may change information encoded by the respective gene segment used. Antibody VH domain sequence analysis by ISM bioinformatics approach that is based on amino acids physicochemical features, enable to distinguish the contribution of the information encoded by VH gene or generated during VDJ gene recombination for antibody-antigen interaction. The data presented in this report revealed the significance of CDRH3 for the interaction of antibody specific for immunogenic molecules while CDRH3 contribution is minor for antibody interaction with nonimmunogenic molecules such as haptens and native mammalian dsDNA. Thus, paratopes might be located in the CDRH3 or VH regions.

AB  - The goal of this report was to propose a model, wherein synergy between the B-cell antigen receptor (BCR) and toll-like receptor (TLR) signaling is involved in the selection of the B-cell precursors of HIV-1 broadly neutralizing antibodies (bnAbs) with long heavy chain complementarity determining regions 3, from immature/ transitional B cells. The model predicts the involvement of Ab/HIV-1 complexes in a way that Ab from the complex binds both BCRs and HIV-1, while on internalization of HIV-1 TLR ligands such as CpG motifs interacts with TLR9. The result of BCR and TLR9 orchestrated signaling is a formation of somatically mutated memory B cells potential precursors of bnAbs. Generated memory B cells continuously exposed to different Ab/HIV-1 complexes can elicit specific bnAb by stochastic somatic hypermutation rather than in the Darwinian process. This new view of the interaction between Ab/HIV-1 complexes and immune system, leading to affinity maturation of the bnAbs in the absence of nominal HIV-1 antigen and BCR interaction, may have implication for the vaccine designed and passive immunization. © 2019, Publicaciones Permanyer.

AB  - Analysis of protein sequences by the informational spectrum method (ISM) enables characterization of their specificity according to encoded information represented with defined frequency (F). Our previous data showed that F(0.367) is characteristic for variable heavy chain (VH) domains (a combination of variable (V), diversity (D) and joining (J) gene segments) of the anti-phosphocholine (PC) T15 antibodies and mostly dependent on the CDR2 region, a site for PC phosphate group binding. Because the T15 dsDNA-reactive U4 mutant also encodes F(0.367), we hypothesized that the same frequency may also be characteristic for anti-DNA antibodies. Data obtained from an analysis of 60 spontaneously produced anti-DNA antibody VH domain sequences supported our hypothesis only for antibodies, which use V gene segment in germline configuration, such as S57(VH31), MRL-DNA22, and VH11, members of the VH1 (J558) and VH7 (S107) gene families. The important finding is that out of seven V gene segments used by spontaneous anti-DNA antibodies, F(0.367) is only expressed by the germline configuration of these three V gene segments. The data suggest that antibody specificity for the phosphate group moiety delineated as F(0.367) is the intrinsic property of the V germline gene segments used, whereas paratope/epitope interaction with antigens bearing this epitope, such as PC or dsDNA, requires corresponding antibody VH conformation that is susceptible to somatic mutation(s). © 2018 Srdic-Rajic, Kohler, Jurisic and Metlas.

AB  - Imidazoline I1 receptor signaling is associated with pathways that regulate cell viability leading to varied cell-type specific phenotypes. We demonstrated that the antihypertensive drug rilmenidine, a selective imidazoline I1 receptor agonist, modulates proliferation and stimulates the proapoptotic protein Bax thus inducing the perturbation of the mitochondrial pathway and apoptosis in human leukemic K562 cells. Rilmenidine acts through a mechanism which involves deactivation of Ras/MAP kinases ERK, p38 and JNK. Moreover, rilmenidine renders K562 cells, which are particularly resistant to chemotherapeutic agents, susceptible to the DNA damaging drug doxorubicin. The rilmenidine co-treatment with doxorubicin reverses G2/M arrest and triggers apoptotic response to DNA damage. Our data offer new insights into the pathways associated with imidazoline I1 receptor activation in K562 cells suggesting rilmenidine as a valuable tool to deepen our understanding of imidazoline I1 receptor signaling in hematologic malignancies and to search for medicinally active agents.

AB  - The clonidine-like central antihypertensive agent rilmenidine, which has high affinity for I-1-type imidazoline receptors (I-1-IR) was recently found to have cytotoxic effects on cultured cancer cell lines. However, due to its pharmacological effects resulting also from alpha(2)-adrenoceptor activation, rilmenidine cannot be considered a suitable anticancer drug candidate. Here, we report the identification of novel rilmenidine- derived compounds with anticancer potential and devoid of alpha(2)-adrenoceptor effects by means of ligand-and structure-based drug design approaches. Starting from a large virtual library, eleven compounds were selected, synthesized and submitted to biological evaluation. The most active compound 5 exhibited a cytotoxic profile similar to that of rilmenidine, but without appreciable affinity to alpha(2)-adrenoceptors. In addition, compound 5 significantly enhanced the apoptotic response to doxorubicin, and may thus represent an important tool for the development of better adjuvant chemotherapeutic strategies for doxorubicin-insensitive cancers.

AB  - A physical and mathematical model identifies similarities between phosphocholine-binding antibodies.A methodology based on the representation of each amino acid of a protein sequence by the electron-ion interaction potential and subsequent analysis by signal processing was used to determine the characteristic or common frequency (in Hz) that reflects the biological activity shared among phosphocholine (PC)-binding antibodies. The common frequency for the variable portion of the heavy chain (VH) of the PC-specific antibodies is found to be at f 0.37 Hz. The VH sequences of the PC-binding antibodies exhibit three subsites for the PC moiety where hypervariable region 2 (CDR2) plays a role in the interaction with the phosphate group. Mutations in this VH region have an impact on the ability of mutant variants to bind PC and its carrier molecule, as well as on the characteristic frequency shift toward f 0.12 Hz for mutants failing to bind both hapten and carrier. The VH sequence of mutants that retain the ability to bind PC still shows f 0.37 Hz, suggesting that this frequency determines PC binding. However, this statement was not confirmed as mutation in another PC subsite impairs PC binding but retains both the phosphate-group recognition and the frequency at f 0.37 Hz. Herein, this finding is discussed to promote the idea that the VH sequence of the PC-binding antibodies encodes the subsite for phosphate-group binding as a dominant functional activity and that only CDR2 of the T15-idiotype antibodies together with FR3 region form an autonomous self-association function represented by the T15VH5073 peptide with f 0.370.05 Hz. Thus, these data confirmed that T15VH50-73 peptide might be used in superantibody technology.

The VH sequences of the PC-binding antibodies exhibit three subsites for the PC moiety where hypervariable region 2 (CDR2) plays a role in the interaction with the phosphate group. Mutations in this VH region have an impact on the ability of mutant variants to bind PC and its carrier molecule, as well as on the characteristic frequency shift toward f 0.12 Hz for mutants failing to bind both hapten and carrier. The VH sequence of mutants that retain the ability to bind PC still shows f 0.37 Hz, suggesting that this frequency determines PC binding. However, this statement was not confirmed as mutation in another PC subsite impairs PC binding but retains both the phosphate-group recognition and the frequency at f 0.37 Hz. Herein, this finding is discussed to promote the idea that the VH sequence of the PC-binding antibodies encodes the subsite for phosphate-group binding as a dominant functional activity and that only CDR2 of the T15-idiotype antibodies together with FR3 region form an autonomous self-association function represented by the T15VH5073 peptide with f 0.370.05 Hz. Thus, these data confirmed that T15VH50-73 peptide might be used in superantibody technology.",

AB  - The group of imidazoline-1 receptors (I-1-IR) agonists encompasses drugs are currently used in treatment of high blood pressure and hyperglycemia. The I-1-IR protein structures have not been determined yet, but Nischarin protein that binds numerous imidazoline ligands inducing initiation of various cell-signaling cascades, including apoptosis, is identified as strong I-1-IR candidate. In this study we examined apoptotic activity of rilmenidine (potent I-1-IR agonist), moxonidine (moderate I-1-IR agonist), and efaroxan (I-1-IR partial agonist) on cancer cell line (K562) expressing Nischarin. The Nischarine domains mapping was performed by use of the Informational Spectrum Method (ISM). The 3D-Quantitative Structure-Activity Relationship (3D-QSAR) and virtual docking studies of 29 I-1-IR ligands (agonists, partial agonists, and antagonists) were carried out on I-1-IR receptors binding affinities. The 3D-QSAR study defined 3D-pharmacophore models for I-1-IR agonistic and I-1-IR antagonistic activity and created regression model for prediction of I-1-IR activity of novel compounds. The 3D-QSAR models were applied for design and evaluation of novel I-1-IR agonists and I-1-IR antagonists. The most promising I-1-IR ligands with enhanced activities than parent compounds were proposed for synthesis. The results of 3D-QSAR, ISM, and virtual docking studies were in perfect agreement and allowed precise definition of binding mode of I-1-IR agonists (Arg 758, Arg 866, Val 981, and Glu 1057) and significantly different binding modes of I-1-IR antagonists or partial I-1-IR agonists. The performed theoretical study provides reliable system for evaluation of I-1-IR agonistic and I-1-IR antagonistic activity of novel I-1-IR ligands, as drug candidates with anticancer activities.

AB  - The production of autoantibodies against a vast array of self antigens, most notably double stranded (ds) DNA, characterized systemic lupus erythematosus (SLE). The purpose of this work is to study specific Ig fractions isolated from normal human serum (NHS) and their effect on the binding of anti-double-stranded deoxyribonucleic acid (dsDNA) antibodies (Abs) to dsDNA. A fraction named immunoglobulin G (IgG)-reactive IgG was purified from total NHS IgG by absorption onto (CNBr)-activated Sepharose 4B linked to intact IgG molecules (IgG-Sepharose column). IgG-reactive IgG was co-incubated with systemic lupus erythematosus (SLE) patients serum and binding of the anti-dsDNA Abs to dsDNA was measured by enzyme-linked immunosorbent assay (ELISA). Co-incubation of SLE patients serum with IgG-reactive IgG resulted in a dose-dependent reduction in binding of anti-dsDNA Abs to dsDNA. A reduction greater than 70% was observed at a concentration of 300 mu g of IgG-reactive IgG per mL of a 400-fold diluted SLE patients serum whereas total NHS IgG, at the same concentration, resulted in a 10% reduction in binding. The purification process used to isolate IgG-reactive IgG was based on interactions between intact Ig rather than on interactions between F(ab)(2) portions. IgG(2) is the predominant immunoglobulin (Ig) subclass in IgG-reactive IgG. Thus, IgG(2) might have an important role in the connectivity characteristics of NHS IgG. The capacity of IgG-reactive IgG to inhibit anti-DNA Ab binding to dsDNA may have potential application in the treatment of SLE. This targeted biological approach may provide an alternative strategy to immunosuppressants. (C) 2011 Elsevier GmbH. All rights reserved.

AB  - We report on characteristics of the first human cell line, PC-MDS, derived from a bone marrow of a patient with therapy-related myelodysplastic syndrome (t-MDS) who had no overt post-MDS leukemia. Classic cytology analyses, immunophenotyping, cytogenetic and molecular genetic procedures were used for characterization of the cell line. PC-MDS cells are positive for the expression of CD13, CD15, CD30, CD33, and CD45 antigen. Positive cytochemical staining and immunophenotype analyses indicated that PC-MDS cells have some characteristics of the early myeloid precursor cell. The karyotype analysis of PC-MDS cell line revealed various numerical and structural changes including those typically associated with t-MDS: del(5)(q13)[7], der(5)t(5;11)(p11;q11)[13], -7[6], del(7)(q31)[2], +20[3], -20[4]. Evaluation of methylation status in a promoter region of p 15, p 16 and MGMT genes showed biallelic hypermethylation pattern of 5 promoter region only in MGMT gene. PC-MDS is the first t-MDS derived cell line, and based on its immunological, cytogenetic and molecular characterization could be a new tool in evaluation of complex biology of MDS and a model for methylation studies.

AB  - Immunoglobulins (Ig) of pooled healthy human sera were purified by affinity chromatography based on their reactivity with human IgG. This Ig fraction represent connected, natural antibodies (NAbs) and here are denoted as antiIgG antibodies. The data revealed that IgG, IgA and IgM isotypes arc constituents of anti-IgG fraction. The ability of antiIgG antibodies to prevent infection of PBMC by HIV-1 was demonstrated. They exhibited different neutralizing activity depending on the phenotype of the tested virus. The efficacy of neutralization was comparable to monoclonal antibodies (MAbs) IgG1b12 at least for the HIV-1 (92HT593B) Strain. These studies suggest that connected antibodies thus, constituents of immune network, could prevent infection by HIV-1. NAbs as essential components of therapeutic molecules of intravenous Ig (IVIg) have a beneficial effect on variety of immunological disorders by affecting the structure, function and dynamics of the immune network. Since, hallmark of HIV-1 infection are immunological disorders we hypothesizes that they might be corrected to some extend by anti-IgG antibodies.
