Abstract: A pharmaceutical composition using natural gonadotropin-releasing hormone (GnRH), and/or some of its mimetic peptides, indistinctly bound by its amino or carboxyl extremes to a carrier molecule; in one case by its carboxyl extreme and in the other case by the amino terminal extreme, thus eliciting a faster and more potent immunological response against the endogenous GnRH hormone. This finally leads to the ablation of the GnRH and consequently of the rest of the involved hormones in the stream GnRH/LH-FSH/Testosterone-(estrogens). An advantage of this formulation consists on facilitating the exposition to the immune system of a greater number of epitopes of the GnRH or its mimetics, minimizing thus the steric hindrance produced by the carriers.

Abstract: The present invention is related to the field of molecular immunology, particularly to a peptide derived from the sequence of interleukine-15 (IL-15), wherein said peptide was optimized to inhibit the biological activity of this molecule. In the present invention, it is shown that this peptide inhibits IL-15-induced T cell proliferation, Tumor Necrosis Factor ? (TNF?) induction and the expression of IL-8 and IL-6 by the IL-15 receptor a subunit (IL-15R?), all these effects mediated by the binding of the peptide to the IL-15R?. The invention is also related to the use of the peptide to treat pathologies where the abnormal expression of IL-15 or IL-15R? is related to the course of the disease, such as rheumatoid arthritis (RA) and prostate cancer.

Abstract: The present invention is related to a method for blocking the infection of cells by dengue virus, based on interfering the direct interaction of the viral envelope protein with a cellular receptor or its indirect interaction with said cellular receptor through a carrier protein, as well as related uses; wherein said cellular receptor is the alpha-2 macroglobulin receptor, also known as the low density receptor-related protein or as CD91, and said carrier protein is human alpha-2 macroglobulin.

Abstract: This invention is related to the Molecular Pharmacology field and especially to the development of peptides useful for treating epithelial tumors and mainly those associated to oncogenic types of HPVs. The main objective of this invention is to identify peptides whose structure permits to block the Casein Kinase II (CKII) phosphorylation domain by direct interaction with such a site. In the present invention it is shown eleven cyclic peptides with different aminoacid sequences which inhibit the CKII phosphorylation in vitro, exhibit cytotoxicity on HPV-16 transformed cells (CaSki) and also increase the sensitivity of these cells to the cytostatic effect of interferon (IFN). Furthermore, the invention relates to the use of these peptides conjugated or fused to other peptides and chemical compounds which penetrates into cells as well as with the use of both peptide and chemical mimetic molecules.

Abstract: The present invention is relative to chimerical peptides, whose primary structure holds at least one segment which inhibits the activation of the NS3 protease of a virus from the Flaviviridae family, they also contain a cell penetrating segment and they are capable of inhibiting or attenuate the viral infection. This invention is also relative to pharmaceutical compounds which contain these chimerical peptides for the prevention and/or treatment of the infection caused by a virus of the Flaviviridae family.

Abstract: Current invention is related to the molecular pharmacology branch particularly to a peptide belonging to the Interleukin-15 sequence (IL-15) which is able to inhibit IL-15 biological activity, analogues or mimetic of such peptides. In the current invention it is shown that the peptide inhibits both IL-15-induced T cells proliferation upon binding to the IL15 receptor a subunit (IL15R?) and TNF?-mediated apoptosis. Besides, this invention is related to the use of this peptide in the treatment of several pathologies where aberrant IL-15 or IL-15R? expression is associated to the disease progression.

Abstract: The present invention relates to five synthetic peptides of pre-M/M protein of Dengue-2 virus, corresponding to amino acid sequences 3-31, 45-67, 57-92, 69-93 and 103-124. The anti-peptide immune response was evaluated in mice. Recombinant fusion proteins were also obtained, including regions of pre-M/M protein. The presence of B cell epitopes in both mice and humans was demonstrated in the pre-M/M protein peptides. Peptides 3-31 and 103-124 elicited neutralizing antibodies against the four serotypes of Dengue virus. Virus-specific proliferative responses were demonstrated in mice immunized with non-conjugated peptides 3-31 and 57-92. Mice immunized with conjugated peptides 3-31, 57-92, and 69-93 were protected when they were challenged with Dengue-2 virus. Thus, the presence of sequential epitopes in Pre-M/M protein of Dengue-2 virus was demonstrated, as well as their relevance in the immune response against this flavivirus.
