The antimicrobial peptides human beta-defensin-1 (hBD1), hBD2, hBD3, and CAP18 expressed by keratinocytes have been implicated in mediation of the innate defense against bacterial infection. To gain insight into Staphylococcus aureus infection, the susceptibility of S. aureus, including methicillin-resistant S. aureus (MRSA), to these antimicrobial peptides(More)
BACKGROUND Activation of T cells is believed to play a critical role in the pathogenesis of psoriasis. Recently, it has been proposed that psoriasis is a T-cell-mediated autoimmune reaction triggered by bacterial superantigen. OBJECTIVE We investigated whether patients with chronic plaque psoriasis bear superantigen-producing Staphylococcus aureus on the(More)
Topical vitamin D3 therapy is one of the mainstays of psoriasis treatment. However, the effectiveness of combination therapy with topical vitamin D3 and corticosteroids is still controversial. It has been reported that topical vitamin D3 treatment following topical corticosteroids is less effective than that without preceding corticosteroid treatment. We(More)
It has been reported that p21, p53, and p16 affect the cell cycle and cell senescence. However, their roles in keratinocyte senescence are not clear. We established primary keratinocyte strains from 15 donors and maintained them until replicative senescence; their population doublings ranged from 5.7-45.2. These strains were classified based on their(More)
