  • Patent number: 11085080
    Abstract: The present invention is related to detecting respiratory diseases using molecular markers as prognostic tool of the evolution of respiratory infection cases. Concretely, during the differential diagnostic of respiratory infections caused by the Syncytial Respiratory Virus and human Metapneumovirus, it will be established the expression pattern of the severity markers of IL-3, IL-33 and IL12p40. The expression pattern of the molecular markers can be defined in biological samplers using ELISA assays, flow cytometry or PCR in real time. The confirmation of the etiological agent of the infection in combination to the pattern definition of the molecular markers IL-3, IL-33 and IL12p40 will indicate a prognostic of the disease severity.

  • Patent number: 9999663
    Abstract: The present invention relates to an immunogenic formulation to be used in mammals against human Metapneumovirus (hMPV), consisting of a lyophilisate of 1×109 ufc/ml of recombinant BCG that expresses the viral protein P of hMPV (of genogroups A1, A2, B1 and B2). The vaccine is derived from the full or partial product of the P gene of hMPV, capable of being used, stabilised and administered in solution without requiring adjuvants. The preparation can also contain combinations of the aforementioned formulations. The formulation is stabilised by means of lyophilisation (conservation range of between 4° C. and 8° C.) in order to be subsequently reconstituted in an adjuvant-free saline solution prior to use.

  • Publication number: 20170196950
    Abstract: The invention relates to a method for producing tolerogenic dendritic cells (tolDCs) with specific antigens, comprising the steps of: (a) culturing precursors of dendritic cells in an animal-serum-free medium, using cytokines, IL-4 and GM-CSF, in order to differentiate same in dendritic cells; (b) producing apoptotic cells; (c) culturing the dendritic cells obtained in step (b) in the presence of compounds having anti-inflammatory activity; (d) co-culturing the dendritic cells from step (d) with the apoptotic cells from step (c), such as to stimulate the endocytosis of the apoptotic cells by the dendritic cells; (e) and, by means of identification based on phenotypic evaluation, determining the production of tolerogenic dendritic cells (tolDCs) with specific antigens. The invention also relates to the tolDC cells produced with said method and to the use of said tolDCs with specific antigens in the production of a drug suitable for the treatment of systemic lupus erythematosus.

  • Patent number: 9273122
    Abstract: The use of monoclonal antibodies specific for respiratory syncytial virus (RSV). Specifically, to a monoclonal antibody IgG2A secreted by the cell line of 8A4/G9 hybridoma specifically directed to the M2-1 viral antigen, which is associated with the nucleocapside of the virus. The antibodies can be used for assays for the detection and/or determination of RSV infection. The antibodies are in the pure state and do not contain any other contaminating biological material. A method for preventing and treating the infection caused by respiratory syncytial virus (RSV) in a given host is provided, including the administration of a composition containing the monoclonal antibodies secreted by the 8A4/G9 hybridoma in sufficient doses to prevent the disease. The antibody can be humanized in order to minimize the possibility of an immune response against the same in the patient.

  • Patent number: 8398993
    Abstract: The present invention describes an immunogenic formulation to be used in mammals against the respiratory syncytial virus (RSV), consisting in the Calmette-Guérin bacillus (BCG) strain or other attenuated Mycobacterium strain that expresses heterologously at least one protein or immunogenic fragment of the RSV subtype A or RSV subtype B strains, originated from proteins NS1, NS2, N, P, M, SH, M2 (ORF1), M2 (ORF2), L, F or G. The genetic material that encodes for these proteins or immunogenic fragments is inserted into the BCG genome or extrachromosomally in one or several copies, which expression is regulated by endogenous or exogenous BCG promoters, either constitutive or inducible. The viral proteins or immunogenic fragments can be expressed by BCG as cytoplasmic-soluble, extracellularly-secreted or cell membrane-bound proteins. The preparation can further contain combinations of previously described formulations. The formulation can be stabilized by freeze-drying (conservation range from 4° C. and 25° C.
