1. Utilização da matriz dérmica acelular e matriz óssea inorgânica/P-15 na preservação das deformidades da crista óssea alveolar após extração dentária em humanos / Ridge Preservation with Acellular Dermal Matrix and Anorganic Bone Matrix Cell-Binding Peptide P-15 following tooth extraction in humans
Background: Preventing ridge collapse with the extraction of maxillary anterior teeth is vital to an esthetic restorative result. Several techniques are available to regenerative procedures and are used for socket preservation. The aim of this study was to analyze by clinical parameters the use of acellular dermal matrix (ADM) and anorganic bovine bone matri

3. Regenerative potential of an anorganic bone matrix/synthetic cell-binding peptide graft usisng the class III furcation lesion model. A histologic and histomorphometric study in dogs. / Avaliação do potencial regenerativo da matriz óssea bovina inorgânica/P15 particulada em lesão de bifurcação grau III. Estudo histomorfométrico em cães
Introdução: A falta de previsibilidade no tratamento periodontal regenerativo de defeito de furca grau III, têm estimulado o estudo de alternativas para melhorar os resultados, através do emprego de diferentes técnicas e biomateriais. Um novo enxerto ósseo enriquecido com peptídeos - Matriz óssea bovina inorgânica/P15 (PepGen P15) - foi desenvolvido

4. Clinical study of cell-binding peptide (PepGen-P15®) application in advanced periodontal lesions of dogs / Estudo clínico da aplicação de peptídeo sintético de adesão celular (PepGen-P15®) em lesões periodontais graves de cães
The aim of this study was to evaluate the attachment loss, periodontal pocket, gingival ressection and II and III furcation lesion response in teeth after 3 and 6 month with collagen cell-binding peptide (PepGen P-15®) graft application. Twenty one dogs from the FMVZ-USP Veterinary Hospital were anesthetized in order to accomplish periodontal treatment a

5. Analysis of structure and function relationships of an autoantigenic peptide of insulin bound to H-2Kd that stimulates CD8 T cells in insulin-dependent diabetes mellitus
The recognition of MHC–peptide complexes by T cells is governed by structural considerations that are determined by the sequences of the individual components and their interaction with each other. We have studied the function of a highly diabetogenic CD8 T cell clone that is specific for insulin B15-23:H-2Kd. We have then related this to modeled MHC–pep

6. Structure of a covalently stabilized complex of a human αβ T-cell receptor, influenza HA peptide and MHC class II molecule, HLA-DR1
An αβ T-cell receptor (αβTCR)/hemagglutinin (HA) peptide/human leukocyte antigen (HLA)-DR1 complex was stabilized by flexibly linking the HA peptide with the human HA1.7 αβTCR, to increase the local concentration of the interacting proteins once the peptide has been loaded onto the major histocompatibility complex (MHC) molecule. The structure of the

7. Identification of B-Cell Epitope of Dengue Virus Type 1 and Its Application in Diagnosis of Patients
Using a serotype-specific monoclonal antibody (MAb) of dengue virus type 1 (DEN-1), 15F3-1, we identified the B-cell epitope of DEN-1 from a random peptide library displayed on phage. Fourteen immunopositive phage clones that bound specifically to MAb 15F3-1 were selected. These phage-borne peptides had a consensus motif of HxYaWb (a = S/T, b = K/H/R) that m

8. Identification of the amino acid sequence in Sindbis virus nsP4 that binds to the promoter for the synthesis of the subgenomic RNA
A gel mobility-shift assay was used to demonstrate the binding of the Sindbis virus transcriptase to the promoter for the synthesis of subgenomic (SG) RNA. The assay made use of a P15 fraction (the cell fraction that is pelleted at 15,000 × g) from cells infected with recombinant vaccinia virions expressing various Sindbis virus nonstructural proteins (nsPs

9. Importance of the Vasoactive Intestinal Peptide Receptor in the Stimulation of Cyclic Adenosine 3′,5′-Monophosphate in Gallbladder Epithelial Cells of Man: COMPARISON WITH THE GUINEA PIG
An EDTA procedure was used to prepare isolated epithelial cells of human gallbladder devoid of endogenous vasoactive intestinal peptide (VIP) as measured by radioimmunoassay. Specific binding sites for VIP were characterized in these cells. At 37°C, the binding of 125I-labeled VIP reached a peak within 20 min and then declined rapidly. At 15°C, binding was

10. Synthetic peptide homologous to the envelope proteins of retroviruses shares a cross-reacting epitope with the CD4 receptor.
A synthetic peptide (CKS-17) homologous to a highly conserved region of the retroviral transmembrane protein p15E was tested for its effect on receptor expression on monocytes. The CKS-17 amino acid sequence is present in several retroviruses including human T-cell lymphotropic virus types I and II and human immunodeficiency virus. The CKS-17 peptide has bee

11. pH-independent murine leukemia virus ecotropic envelope-mediated cell fusion: implications for the role of the R peptide and p12E TM in viral entry.
Murine leukemia virus ecotropic and amphotropic envelope expression vectors were genetically engineered to generate truncations of the p15E TM cytoplasmic tail. The ecotropic construct CEET has the entire cytoplasmic tail of TM deleted, while the CEETR construct has only the R peptide portion of the tail deleted, thereby producing a TM subunit (p12E) that is

12. Phosphorylation reverses the membrane association of peptides that correspond to the basic domains of MARCKS and neuromodulin.
Several groups have observed that phosphorylation causes the MARCKS (Myristoylated Alanine-Rich C Kinase Substrate) protein to move off cell membranes and phospholipid vesicles. Our working hypothesis is that significant membrane binding of MARCKS requires both hydrophobic insertion of the N-terminal myristate into the bilayer and electrostatic association o
