Occupational allergies, such as allergic rhinitis, contact dermatitis, or asthma, have become much more prevalent in the past twenty years. There are numerous occupational allergens that have been identified as the cause of these symptoms. They can be classified as either high molecular weight (HMW) or low molecular weight (LMW). Common HMW allergens include animals, latex, molds, and soy, and common LMW allergens include isocyanates, acid anhydrides, nickel, and platinum. As new materials and chemicals are manufactured, there is a strong possibility that we will continue to see novel allergens emerge. Therefore, it is important to better our knowledge and understanding of occupational allergies and their pathogenesis. If we are able to identify potential allergens, before clinical symptoms are observed, employers can take necessary precautions to minimize or eliminate their employee's exposure.

We are interested in articles that explore aspects of occupational allergies including its classification, pathogenesis, prevention, and treatment. Potential topics include, but are not limited to:

• Identification of high-molecular-weight allergens, for example, soy, mold, and latex
• Tests for assessing chemical allergens such as local lymph node assays (LLNAs)
• Identifying mechanisms of haptenation of chemicals
• Animal models of low-molecular-weight allergen-induced (e.g., isocyanates) rhinitis and asthma
