摘要:
The present invention relates to a method for obtaining an antigen-loaded dendritic cell in vitro comprising contacting an immature dendritic cell with an immunogen, preferably a HIV immunogen, and simultaneously, during at least part of said step, placing said immature dendritic cell under conditions adequate for maturation. The invention relates also to HIV-1 immunogens lacking a functional integrase protein.
摘要:
The present invention refers to methods and compositions to prevent viral entry into cells expressing the CD169/sialoadhesin surface receptor by inhibiting the coupling of the sialyllactose molecule contained in the viral membrane gangliosides to the CD169/sialoadhesin receptor. The invention also pertains to vaccine compositions based on dendritic cells loaded with an antigen of interest whereby the vaccine is provided together with a composition capable of preventing viral entry into cells expressing the CD169/sialoadhesin. Moreover, the invention relates to diagnostic and therapeutic compositions that can be specifically delivered to enveloped virions wherein the diagnostic/therapeutic agent is coupled to CD169/sialoadhesin.
摘要:
The invention relates to methods for the identification of HIV-infected patients capable of controlling viral load based on the determination of the expression levels of different miRNAs. In addition, the invention also relates to methods for controlling HIV infection by using some of the differentially expressed miRNAs or polynucleotides encoding said miRNAs as well as to compositions comprising a miRNA or a polynucleotide encoding said miRNA and an anti-HIV agent.
摘要:
The invention relates to a method for rapid immunogen selection (RIS) based capable of eliciting neutralizing antibodies based on the binding a library of recombinant viruses containing randomized variants of a surface polypeptide displayed to said neutralizing antibodies. The invention relates as well to the use of the immunogens isolated according to the RIS method of the invention in medicine for the treatment of diseases caused by a virus and in diagnosis for the identification of neutralizing antibodies in a patient.
摘要:
The present invention relates to an antibody that specifically binds to sialic acid-binding Ig-like lectin 1 (CD169/Siglec-1), as well as the antigen-binding fragment, the kit and the pharmaceutical composition comprising said antibody. The invention also relates to the use of the antibody and the pharmaceutical composition in the prevention and/or the treatment of infection by enveloped virus and, in particular, by an infection by a virus of the filoviridae family, an infection by an Orthopneumovirus, a coronavirus infection or an arenavirus infection.
摘要:
The present invention refers to antibodies or antigen-binding fragments thereof that bind the SARS-CoV-2 spike protein with high affinity and subsequent high neutralizing activity against SARS-CoV-2. It also discloses polynucleotides and expression vectors encoding said antibodies or antigen-binding fragments, and host cells comprising said nucleotides and vectors, as well as their use in treatment or prevention of a disease caused by a SARS-CoV-2.
摘要:
The invention relates to polynucleotides and recombinant cell strains comprising the polynucleotides and the uses thereof for the delivery of the polypeptides encoded by the polynucleotides to a subject in need thereof. In particular, the invention refers to polynucleotides comprising a polypeptide of interest, auxotrophy-complementing genes and the use thereof in a mycobacterial double auxotrophic host cell to achieve the stable expression of the polypeptide of interest by using an antibiotic-free plasmid selection system.
摘要:
The invention relates to an enhanced method for rapid immunogen selection (RIS) based on the binding a library of recombinant viruses containing randomized variants of a surface polypeptide displayed to said neutralizing antibodies. The invention relates as well to the use of the immunogens isolated according to the RIS method of the invention in medicine for the treatment of diseases caused by a virus and in diagnosis for the identification of neutralizing antibodies in a patient.
摘要:
The invention relates to a method and a diagnostic kit for monitoring HIV specific T cell responses and identifying subjects capable of controlling HIV progression or preventing HIV infection altogether. The method is based on the combined use of boosted flow cytometry and toggle peptides and can cover a large set of effector functions. The method is also suitable to detect T cell responses of any desirable cytokine or combination of cytokines to any pathogen.
