| abstractText | Mice with a targeted disruption of the Rel / NF-kappaB family member RelB develop a complex inflammatory phenotype and hematopoietic abnormalities. RelB-deficient (relB(- / -)) mice were clinically normal until 4 - 10 weeks after birth when thickening of the skin and hair loss developed. Histological and immunohistochemical evaluation of relB(- / -) skin lesions revealed hyperkeratosis and marked epidermal hyperplasia. Many CD4(+) T cells and eosinophils mixed with lesser numbers of CD8(+) T cells and neutrophils were present in the dermis. There was a moderate increase of MHC class II-positive dermal dendritic cells and dermal mast cells. Increased expression of Th2 cytokines correlated with increased mRNA levels of eotaxin and CCR3 in relB(- / -) skin. The dermatitis did not develop in the offspring of relB(- / -) mice crossed with transgenic mice that lack peripheral T cells, demonstrating that the skin lesions were T cell dependent. The dermatitis observed in RelB-deficient mice had many similarities with atopic dermatitis in human patients including infiltrating CD4(+) T cells and eosinophils in the skin, increased number of eosinophils in the blood and increased serum IgE. Thus, the relB(- / -) mouse should be a useful model to study the pathogenesis of this common allergic human disease. |
