TRADD and inflammation: Furthermore, we observed that liver and lung inflammation as well as splenomegaly and the defect of splenic structure were not altered by keratinocyte-specific depletion of TRADD in Sharpincpdm/cpdm mice (Figure 6A,B), providing further support for the notion that the development of extracutaneous organ inflammation in Sharpincpdm/cpdm mice occurs independently from the skin lesions.
