CCR3 and CXCR3 as drug targets for allergy: principles and potential.

Atopic disorders include a range of conditions such as allergic asthma, -rhinitis, -conjunctivitis, -dermatitis, food and drug allergies and anaphylaxis. Induction of T helper (Th)-2 immune response with consequent IgE dependent eosinophil, basophil and mast cell mediated tissue damage is the characteristic feature of allergies. The mechanism underlying this unique and long appreciated feature of allergy is being elucidated at the molecular level with advances in our knowledge of the chemokine system.

An ELISA-based method for measurement of food-specific IgE antibody in mouse serum: an alternative to the passive cutaneous anaphylaxis assay.

Passive cutaneous anaphylaxis (PCA) assay has been a gold standard method to measure allergen-specific IgE antibody (ASIgE Ab) levels in allergy mouse models. Many factors including stringent guidelines for laboratory animal use make PCA a difficult choice. Therefore, alternative methods are needed that can be readily applied for measurement of specific IgE antibody levels in mouse serum.

Relative immunogenicity of commonly allergenic foods versus rarely allergenic and nonallergenic foods in mice.

Food allergies affect 6 to 8% of children and 2% of adults in the United States. For reasons that are not clear, eight types of food account for a vast majority (approximately 90%) of food-induced hypersensitivity reactions. In this study, C57Bl/6 mice were used to test the hypothesis that commonly allergenic foods are intrinsically more immunogenic than rarely allergenic or nonallergenic foods in allergy-susceptible hosts.

Chemokines in health and disease.

Chemokines belong to a large family of structurally related proteins that play a pivotal role in immune system development and deployment. While a large number of chemokines (approximately 50) and their receptors (approximately 20) have been identified from humans or mice, only a few are known in domestic veterinary species. Recent data implicate CXCL8 (old name, IL-8), CXCL10 (old name, IP-10) (both CXC chemokines) and CCL2 (old name, MCP-1) (a CC chemokine) in veterinary infections, inflammatory diseases or reproduction.
