摘要:
This invention describes a pharmaceutical compound which has the capsid protein of Dengue virus and which is capable of inducing, in the receptor, a protective immune response before the viral challenge, without inducing the Ab-dependent enhancement phenomenon.
摘要:
Method for the insertion of protein antigens, of recombinant or synthetic origin, in outer membrane vesicles of Gram-negative bacteria without disruption of the vesicle structure, therefore maintaining the immunogenicity and immunostimulatory properties of said vesicles, and with the reported advantage that the immune response generated against the incorporated antigen is superior to the one generated when the antigen is administered alone. The resultant vaccine formulations are useful to increase protective capacity of existing vaccines and allow to extend it against different pathogens, in diseases of bacterial, viral, cancerous or other etiology. The referred formulations are applicable in the pharmaceutical industry as vaccines for therapeutic and preventive use in humans.

The invention relates to the field of immunology, endocrinology and oncology and, in particular, the generation of a combined immune response to determined growth factors and hormones. A synergic effect, outlined herein, between growth regulating factors (EGF, TGF and VEGF) and hormones involved in the sexual hormones release cascade or reproduction (GnRH, LH, FSH) stimulates the anti-tumor response which is expressed as a reduction in the tumor mass and an increase in the survival time.

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.
摘要:
A pharmaceutical composition using natural gonadotropin-releasing hormone (GnRH), and/or some of its mimetic peptides, indistinctly bound by its amino or carboxyl extremes to a carrier molecule; in one case by its carboxyl extreme and in the other case by the amino terminal extreme, thus eliciting a faster and more potent immunological response against the endogenous GnRH hormone. This finally leads to the ablation of the GnRH and consequently of the rest of the involved hormones in the stream GnRH/LH-FSH/Testosterone-(estrogens). An advantage of this formulation consists on facilitating the exposition to the immune system of a greater number of epitopes of the GnRH or its mimetics, minimizing thus the steric hindrance produced by the carriers. This invention has a direct application in the castration of pets and animals of economic interest, in the control of human fertility as well as in the treatment of hormone-sensitive tumors, such as that of the prostate, the breast, ovary, the endometry, testicles, hypophysis, salivary glands and other kinds of human tumors.

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.
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:
The invention relates to the use of Epidermal Growth Factor (EGF) in a preferably-injectable pharmaceutical composition which is administered by means of infiltration into and around chronic cutaneous ischaemic lesions in order to prevent diabetic foot amputation. Said composition can be administered to recently-created surgical surfaces damaged by the effect of acute reperfusion with oxygenated blood following prolonged ischaemia, thereby preventing further surgical procedures and favouring the preservation of the extremity. The aforementioned composition can be used to improve (i) the cell microenvironment, thereby increasing the reparative and defensive capacity and viability of the is tissues and (ii) the cicatrisation of cutaneous ischaemic lesions, thereby stimulating cell proliferation. The invention is suitable for use in human, veterinary and experimental medicine, specifically in vascular angiology and surgery, dermatology, burn treatment and reconstructive surgery and geriatric medicine. Said composition can be used for recalcitrant ulcers which are associated with lesions in the macro and/or microvasculature, patients with inadequate lymphatic and/or venous return and ulcers or other lesions which are difficult to cicatrise and/or heal.
摘要:
The present invention is related to the field of medicine, particularly to the use of new adjuvant formulations with vaccine antigens. The technical objective pursued with this invention is, precisely, the development of formulations that are able to increase and/or modulate the immune response of the organism to vaccine antigens in the serum and the mucous lining. With this aim, a formulation was developed that contained as the main components the surface antigen of the hepatitis B virus and the acemannan in adequate proportions. As an extension of this result, formulations were developed in which a) HBsAg was used as the homologous or heterologous antigen carrier b) delivery systems of particulated antigens and c) soluble antigens, combined with the acemannan in specific proportions. The formulations of this invention are applicable in the pharmaceutical industry as vaccine formulations for human and veterinary use.
