Abstract: The present invention relates to cytokine activity regulator molecules (CARMs) and their use in controlling the action of cytokines, particularly chemokines. In particular, the invention relates to CARMs that are derived from parasite salivary glands. The invention also relates to the use of CARMs in the treatment of diseases and allergies and in the production of vaccines that protect mammals, including humans, against the transmission of pathogenic (disease-causing) micro-organisms by certain parasites.

Abstract: The invention relates to methods for the identification of novel receptors and/or novel ligands. The invention is based on the concept that parasites have developed a number of biologically active compounds in their saliva to cope with the defense mechanisms of the host organisms on which they feed and to manipulate the biological functions of host molecules to their advantage. These saliva compounds can be used to identify novel molecules within the host systems. Furthermore, these saliva compounds can be used to elucidate the functions of molecules whose existence is already known.

Abstract: The present invention relates to novel protease inhibitor proteins that have been identified in ticks. These proteins may be used as components of vaccines, as inhibitors of mast cell tryptase, in detection of mast cells and in the isolation and purification of mast cell tryptase. The invention also relates to the control of diseases and injury caused by parasites in animals and humans and to the use of the proteins of the invention in the treatment of certain diseases and allergies.

Abstract: The invention relates to the discovery that various proteins isolated from ticks are effective in the treatment and prevention of allergic rhinitis. These proteins may most suitably be applied to an effected area and are thus effective to treat this condition and to ameliorate its symptoms.
