Embodiment

[0026] To test the efficacy of the present invention, a fusion protein between the 91 amino acid long extracellular domain B (EDB) of human and mouse fibronectin and the bacterial antigen E. coli thioredoxin with a size of approximately 10 kD was used as a vaccine Antigens to study their effects in animal models. The EDB domain is extremely highly conserved and nearly identical in all placental mammals studied. This fusion protein is produced almost homogeneously in prokaryotic hosts ( figure 2 ). Thioredoxin-EDB-fusion protein was then injected into mice together with adjuvant. After 3 weeks, the mice received a booster dose of the vaccine, and after 5 weeks of treatment, the sera from these animals were tested for the amount of anti-EDB antibodies produced. as from image 3 As seen in , all animals showed high titers of anti-EDB antibodies, whereas all controls were negative. This shows that the vaccine has the ability to induce a large amount of anti-EDB antibody prod...

Abstract

The invention relates to a composition for the treatment of various cancers. The composition is a vaccine containing sequences of EDB, EDA, annexin A1, endosialin, C domain of tenascin C or magic roundabout (MR) or fragments thereof as single or in a combination coupled to one or several heterologous foreign carrier molecules. The vaccine will produce antibodies that are directed against self proteins which are preferentially expressed in and around tumor vessels. The vaccine is preferably administrated together with an adjuvant.

Description

technical field [0001] The present invention relates to a novel approach designed to stimulate the immune system to produce antibodies that target tumor blood vessels almost exclusively. These antibodies against self-proteins that are preferentially expressed in and around tumor blood vessels lead to an immune attack on tumor blood vessels that induces a marked slowing of tumor growth. Although the present invention relates generally to vaccines for use in mammals, preferred embodiments relate to vaccines for use in humans, dogs, cats or horses, and the present invention will generally refer to such vaccines for use in humans, canines, felines Vaccines for use in animals and equines are described. Background technique [0002] Angiogenesis - the formation of new capillaries - is critical during development and in physiological conditions that require angiogenesis, such as wound healing and the menstrual cycle. However, in healthy males, angiogenesis is rare and the endothe...
