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: The present invention is related with the field of the medicine, particularly with the use of an APL peptide or its analogues derived from the human heat shock protein of 60 kDa, for the manufacture of a pharmaceutical composition for the treatment of Crohn's disease, ulcerative colitis and diabetes mellitus type 1. This peptide is biodistributed into the gastrointestinal tract and also promotes the induction of apoptosis in activated intestinal lamina propria and peripheral blood T cells of patients with Crohn's disease. Furthermore, this peptide induces apoptosis in mononuclear cells of patients with diabetes mellitus type 1.

Abstract: Peptides of human heat shock protein of 60 kDa, that constitute epitopes for T cells, as well as their derived peptides, which are modified at the contact sites with the MHC molecule, are useful to induce mechanisms of peripheral tolerance, in particular mechanisms of anergy or mediated by clones of regulatory T cells in patients with Rheumatoid Arthritis. The invention also refers pharmaceutical compositions comprising such peptides for the treatment of Rheumatoid Arthritis.

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.
