Abstract: Chimeric antigen comprising multimeric aggregates of the extracellular domain of the programmed death ligand 1 (PD-L1) with a reduced binding capacity to the PD-1 and CD80 receptors as compared to the native PD-L1 molecule. The invention further discloses pharmaceutical compositions including said chimeric antigen and at least a pharmaceutically acceptable vaccine adjuvant. The chimeric antigen is used for the manufacturing of a drug to treat cancer or its metastases. The invention also discloses a method of treating cancer or its metastases in a subject in need thereof, characterized by the administration of a therapeutically effective amount of the pharmaceutical composition comprising the chimeric antigen described herein.

Abstract: Polypeptides comprising functional mutants of an isoform of the human vascular endothelial growth factor A (VEGF-A) folded in a non-natural re-arrangement, where the second and fourth cysteine of the mutant's polypeptide chain is only forming intramolecular bridges, while the seventh and eight are only part of intermolecular bonds. The invention further comprises antigenic preparations containing at least one of these polypeptides, and the pharmaceutical compositions comprising such antigenic preparations and vaccine adjuvants. The antigenic preparations according to the invention are used in the manufacturing of a drug, for the treatment of diseases related to the increment of angiogenesis, inflammation, and immunosuppression, as well as for the restoration of the immune system.

Abstract: The invention discloses a pharmaceutical combination comprising epidermal growth factor (EGF) and the hexapeptide secretagogue GHRP6, useful for the restoration of brain damage, by stimulating mechanisms of differentiation and neuronal specialization in undifferentiated cells residing in the central nervous system or in neuronal cells. The invention also encompasses the use of the above mentioned biomolecules in the manufacture of a pharmaceutical combination for the restoration of brain damage. In addition, the invention provides a method of restoring brain damage in which a therapeutically effective amount of a pharmaceutical combination comprising EGF and GHRP6 is administered to a patient in need thereof. The efficacy of the pharmaceutical combination has a broad therapeutic window: it is independent of whether the pharmacological intervention occurs in the first or further hours after the brain damage, which broadens the therapeutic window.

Abstract: The invention is relate with a pharmaceutical composition comprising peptide type APL called identified as SEQ ID No. 1, sodium acetate buffer at pH 3.9-4.7; and at least one stabilizing sugar selected from sucrose or trehalose. This pharmaceutical composition is useful for manufacture of a medicament for treating inflammatory diseases related to an increase of neutrophils or citrullination of proteins. These inflammatory diseases include rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), ankylosing spondylitis (AS), Alzheimer's disease, and hepatic and pulmonary fibrosis. The invention also discloses a method for the treatment of these diseases, through effective therapeutic administration of the pharmaceutical composition of APL-type peptide.

Abstract: The present invention describes peptides comprising phycocyanobilin (PCB), as well as the medical use of said peptides and that of PCB, due to the neuroprotector and/or neuroregenerative effects identified for them. Furthermore, pharmaceutical combinations of said peptides and of PCB with proteins or other peptides with synergic effect justify their use for ischemic or neurodegenerative CNS disease treatment.

Abstract: The present invention describes a method of selective peptide isolation for the identification and quantitative analysis of proteins in complex mixture. The method comprises the selective isolation from every protein of those peptides that neither contain arginine nor histidine (NHNR peptides), and the determination of the relative concentrations of one or several proteins in different samples from the ratio between the areas of the estimated theoretical spectra for the NHNR peptides labeled with different isotopes in each sample. The determination of the relative concentration of proteins is valid for any type of isotopic label of the NHNR peptides. The method avoids the separation and purification of the proteins present in a complex mixture, and the analysis of all peptides generated from the enzymatic digest of the samples. The method is applicable to the identification of proteins with vacunal, therapeutic and diagnostic aims.
