摘要:
The present invention relates to antimicrobial peptides, isolated and purified from extracts of tilapia (Oreochromis niloticus) gills. Such peptides may be produced by chemical synthesis or by expression in heterologous systems, such as bacteria and yeasts, by conventional molecular biology techniques. These peptides show antimicrobial activity against various organisms, including Gram positive bacteria, Gram negative bacteria, fungi and viruses. The invention also includes compositions to for controlling pathogens comprising these antimicrobial peptides. The use of such peptides in vaccine preparations, as molecular adjuvants, is also part of the invention.

Formulation of vaccine antigens, containing as main components: a—) one or several DNA expressing one or several proteins in the immunized individuals and b—) a viral antigen, in appropriate proportions. Development of new formulations, minimizing the number of components that enhance and diversify the spectrum of immune response against different pathogenic entities and generating combined vaccines against pathogens.These formulations can be applied in the pharmaceutical industry for preventive and-or therapeutic use in human.

The present invention reveals human recombinant antibodies that recognize the human Vascular Endothelium Growth Factor A (VEGF-A), block its interaction with the VEGFR2 receptor, and interfere with its proliferative effect in vitro and pro-angiogenic effect in vivo. The antibodies identify an epitope on human VEGF-A different from any other previously reported, and were obtained by combining one immunoglobulin light chain variable region with other three heavy chain ones. The antibodies were obtained by human immunoglobulin variable region mutagenesis, and can be employed for the immunotherapy of pathological entities associated with to an increase in vasculature, such as age-related macular degeneration, cancer, and others.

The current invention describes chimeric vaccine antigens against the virus that causes the Classic Swine Fever (CSFV). Such vaccine antigens are based on viral subunits coupled to proteins able to stimulate cellular and humoral immune system. Chimeric antigens can be produced in expression systems that guarantee a correct tertiary structure folding of the chimeric molecules, which constitute the essence of the current invention. The vaccine formulations containing such chimeric antigens induce an early and potent immune response on vaccinated pigs and confer full protection against CSFV. Moreover, the resultant vaccine formulations prevent the viral transmission from sows to their offspring. The chimeric antigens, as well as the resultant vaccine formulations, can be applied in animal health as vaccines for preventive use in swine.

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.

Vaccine composition containing IL-15 for active immunization to treatment diseases related to over-expression of this cytokine. The technical aim pursued in this invention is to inhibit IL-15 activity through development of a therapeutic vaccine which elicits IL-15 neutralizing antibodies in the immunized host.IL-15 can be presented in this vaccine composition either alone or coupled to a carrier such as the P64k protein with a vaccine adjuvant such as Aluminum hydroxide.Besides, this invention is related to the use of this vaccine for treatment of Rheumatoid arthritis and other IL-15 over-expressing related diseases, and leukemia, where this cytokine acts as a growth factor.

Current invention is related to the molecular pharmacology branch particularly to a peptide belonging to the Interleukin-15 sequence (IL-15) which is able to inhibit IL-15 biological activity, analogues or mimetic of such peptides. In the current invention it is shown that the peptide inhibits both IL-15-induced T cells proliferation upon binding to the IL15 receptor α subunit (IL15Rα) and TNFα-mediated apoptosis.Besides, this invention is related to the use of this peptide in the treatment of several pathologies where aberrant IL-15 or IL-15Rα expression is associated to the disease progression.

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.
