Background: Severe refractory atopic dermatitis (AD) is a chronic, debilitating condition that is associated with elevated serum immunoglobulin E (IgE) levels. Thymic stromal lymphopoietin (TSLP), thymus and activation-regulated chemokine (TARC) and OX40 ligand (OX40L) are important immunologic factors involved in the pathogenesis of AD. Omalizumab, an anti-IgE antibody indicated for use in allergic asthma, is implicated in regulating allergen presentation by dendritic cells and the T cell response during the effector phases of allergic disease.

Breast-feeding provides protection against infections and contains numerous factors that modulate and promote the development of the infant immune system. These factors include secretory IgA, antimicrobial proteins like CD14, cytokines, and fatty acids. Studies examining the role of breast-feeding in the development of allergic disease in infants demonstrate potentially protective as well as neutral or nonprotective effects, likely due to the heterogeneity in their study design.

To identify potential molecular determinants of tumor biology and possible clinical outcomes, global gene-expression patterns were analyzed in the primary tumors of patients with metastatic renal cell cancer by using cDNA microarrays. We used grossly dissected tumor masses that included tumor, blood vessels, connective tissue, and infiltrating immune cells to obtain a gene-expression "profile" from each primary tumor. Two patterns of gene expression were found within this uniformly staged patient population, which correlated with a significant difference in overall survival between the two patient groups.
