The Deadline for early registration is August 20th 2009. After this time the fees double, so make sure you register early!

The Agenda includes:
Identification of the major allergens in saliva of Culicoides nubeculosus (biting midge). - Dr Doug Wilson, University of Bristol, UK. 
Insect bite hypersensitivity (IBH) is an allergy of horses to the bites of midges [Culicoides spp.].  Affected horses develop an acute phase response following intradermal challenge with Culicoides salivary gland proteins followed by a late phase response in which skin biopsies show increased numbers of infiltrating T-cells, mast cells, eosinophils and IgE producing B-cells.  Symptoms include pruritis, hair loss, serous effusion and haemorrhage followed by a chronic dermal fibrosis, and hyperkeratosis.  Current research has focused on identifying the abundant salivary gland proteins of Culicoides that act as allergens; with a long term goal of developing an effective immunotherapy for this condition.

Genetics of Canine Atopic Dermatitis: A Suitable Model for the Human Condition? - Shona Wood, Faculty of Veterinary Sciences, The University of Liverpool, UK
The use of canines as a model for human disease is advantageous because different breeds form genetically isolated populations in strong linkage disequilibrium. This is of benefit in genetic study because less genetic markers are required to find an association with the disease and smaller sample sizes can be used to find these associations, relative to human genetic studies.  My work has focused on the identification of the genetic factors causing cAD. By using mRNA expression microarray, qPCR validation and literature searches candidate genes for cAD have been identified. Moreover a whole genome scan was performed using the Illumina SNP chip to identify potentially causative SNPs. These data informed a large scale case/control comparison of SNP frequencies using the Sequenom platform. I will discuss the results of this study in terms of the similarities with the human condition and the use of the dog as a disease model for humans.

The pathogenesis of canine atopic dermatitis - Dr Tim Nuttall, The University of Liverpool, UK.
Canine atopic dermatitis (AD) is a common inflammatory dermatosis with a complex pathogenesis. It is possible that epidermal barrier defects enhance exposure to allergens, irritants and micro-organisms. Most cases possess IgE to environmental allergens (10-20% of cases appear to be non-allergic), which bind to FcεRI on Langerhans cells, enhancing allergen capture, and mast cells, mediating activation. Acute lesions are dominated by TH2-type chemokines and cytokines that recruit and activate eosinophils and other cells. Subsequent self-trauma, keratinocyte activation and microbial colonisation induce TH1-mediated chronic cell-mediated inflammation. Failure of T-regulatory cell mechanisms may prevent resolution.
 
Talk Title to be confirmed - Dr Petra Roosje, University of Bern, Switzerland

Mechanisms of allergy and their diagnostic relevance  - Dr Carsten B. Schmidt-Weber,  Imperial College, London, UK.
Allergy disease are caused by immunologic allergen tolerance. Recent developments in the understanding of the immune system dramatically changed our view on the cause of this loss of immune tolerance. Consequently diagnosis of this immunologic disease requires more comprehensive approaches.

The Deadline for abstract submissions is August 10th 2009.Abstracts will be accepted for poster and oral presentation and there will be a best poster prize. All accepted abstracts will be published in the *meeting proceedings
