摘要:
The present invention is related with the isolation and cloning of a new gene, the production of the protein encoded by this gene by using recombinant systems, and the use of this antigen in a vaccine formulation as a purified protein and/or naked DNA, to induce an immune response in aquatic organisms against different ectoparasite species, including the known as sea lice, and pathogens associated with these infestations. The vaccine preparations, administered by oral route, immersion bath or injection, demonstrated its efficacy by producing IgM humoral immune response and reducing the number of parasites per fish in the vaccinated fishes.

The present invention relates to a pharmaceutical composition that comprises polymeric microspheres containing epidermal growth factor (EGF) for the application, by the parenteral route, into the lower limbs of diabetic patients with cutaneous chronic ischemic ulcerative wounds. The pharmaceutical composition described herein, in contrast with the state of the art, is useful because reduce the administration frequency during the treatment and allows for the healing of the ulcerative wounds in a shorter time interval with respect to the injection of equivalent quantities of non-encapsulated EGF.

The present invention is related with the field of Biomedicine. It comprises the engineering of the Pertactin protein (Prn) and using it as part of bacterial vaccines, and more precisely, as part of acellular vaccines against Bordetella pertusis. The engineered Prn molecules comprise on their structure polimorfisms from different B. pertussis strains, and induce immune responses with protective capacity and opsonophagocytic activity when assayed as vaccines, higher than that generated by other pre-existing vaccines. The engineered Prn variants of the present invention are applicable in human and veterinary medicine.

This invention relates to a medicine for humans, and particularly to a pharmaceutical combination comprising Epidermal Growth Factor (EGF) and Growth Hormone secretagogue hexapeptide (GHRP) for use in preventing tissue damage due to blood flow suppression by enhancing tissue repair following ischemic damage. The aforementioned combination may be applied as a single pharmaceutical composition. Alternatively, an individual may also receive both EGF and GHRP in a separate manner but within a single therapeutic regime to enhance cellular survival when organs are subjected to blood flow deprivation for a critical period of time. This combination attenuates reactive oxygen species (ROS) formation and its associated cytotoxicity. It is also useful in promoting cellular survival when tissue or organs are exposed to prolonged ischemic periods. The combination is useful as a prophylactic agent in those subjects prone to multiple organ failure (MOF) such as burn victims, multiple trauma patients, hypoxic neonates, acute respiratory distress syndrome patients, and necrotizing enterocolitis patients.

The invention relates to HIV chimeric gene formed by the union of fragments of different genes of said virus, wherein said fragments contains epitopes for cytotoxic T cells (CTL) or HIV-1 auxiliary T cells, which are presented by a wide range of antigens of type Major Histocompatibility Complex (HLA-I). Recombinant poxviruses are obtained from said genes, which are useful for prophylactic and therapeutic vaccination against HIV/AIDS infections, are capable of generating a protective immune cell response in vaccinated laboratory animals and are recognized by the CTL lymphocytes of HIV/AIDS patients.
摘要:
The present invention is related to the obtaining of chimeric chains coding for proteins capable of inducing, in the recipient, a serotype-specific and protective humoral immune response against the infection by the Dengue virus, thus eliminating the effects of the serotype-nonespecific viral immunoenhancement that causes hemorrhagies and clinical complications described for this kind of pathology. These chimeric chains of nucleic acids are composed by the specific combination of fragments belonging to the gene of a mutated protein from Neisseria meningitidis with dehydrogenase activity and fragments that codify for a region of the envelope (E) protein from the Dengue virus which, when inserted to an expression vector, give rise to chimeric proteins with particular properties. The resultant chimeric molecules from this invention are applicable to the pharmaceutical industry for the obtaining of vaccine preparations and diagnostic means of high serotype-specificity to be used in humans.
摘要:
An artificial promoter characterized for been a chimerical recombinant DNA molecule such that, when introduced in any class of plant cells, promotes high expression levels of any DNA molecule fused to its 3′ end. The basic genetic elements of the molecule described here are: a core promoter with a consensus TATA box, followed by an Exon/Intron/Exon region and a translation enhancer element, all of them artificially constructed. Transcription regulatory elements can be inserted upstream of the promoter here described to confer temporal-, organ- or tissue-specificity to the expression. The designed artificial genetic elements can be functionally inserted between any promoter active in plant cells and any DNA sequence to increase its transcription/translation levels.
摘要:
The present invention is concerned with a method for the isolation of a nucleotide sequence which codes for a protein having a molecular weight of about 64,000 daltons, which is located on the outer membrane of N. meningitidis, as well as with the recombinant DNA obtained therefrom, which is used for the transformation of a host microorganism. The technical object pursued with the invention is the identification of a nucleotide sequence coding for a highly conserved and common protein for the majority of pathogenic Neisseria strains, the production of this protein with a high level of purity and in commercially useful amounts using the recombinant way, so that it can be used in diagnostic methods and vaccine preparations with a broad immunoprotection spectrum.
摘要:
The present invention describes a method to inhibit replication of the human immunodeficiency virus (HIV) by negatively modulating or altering the cytoskeleton, more precisely the proteins forming the intermediate cytoskeletal filaments, wherein the the proteins are vimentin and/or keratin-10. The replication of the virus is inhibited in human cells by intervening in the structure of these proteins. The present invention is also related to the use of agents, including peptides and/or interfering RNA and/or lipidic compounds, the agents producing a negative modulation or alteration of the cytoskeleton to prevent or to treat the HIV infection.
