TSLP and Alzheimer disease: Tape-stripping also triggers mechanical injuries which activate keratinocytes and upregulate thymic stromal lymphopoietin (TSLP) expression by keratinocytes and mRNA expression of inflammatory cytokines, all of them involved in the polarization of skin DCs to elicit a Th2 response seeing that a link between TSLP expression and the pathogenesis of AD has been shown in several mouse models [22-24].
