Psoriasis, which is regarded as a T-cell-mediated chronic inflammatory skin disease, is characterized by hyperproliferation and poor differentiation of epidermal keratinocytes. In this study, we aimed to determine the in vivo effect of a potentially probiotic strain, Lactobacillus pentosus GMNL-77, in imiquimod-induced epidermal hyperplasia and psoriasis-like skin inflammation in BALB/c mice. Oral administration of L. pentosus GMNL-77 significantly decreased erythematous scaling lesions. Real-time polymerase chain reaction showed that treatment with L. pentosus GMNL-77 significantly decreased the mRNA levels of proinflammatory cytokines, including tumor necrosis factor-alpha, interleukin (IL)-6, and the IL-23/IL-17A axis-associated cytokines (IL-23, IL-17A/F, and IL-22) in the skin of imiquimod-treated mice. In addition, we found that L. pentosus GMNL-77 decreased the spleen weights of the imiquimod-treated group and reduced the numbers of IL-17-and IL-22-producing CD4(+) T cells in the spleen. In conclusion, the present study provides insight into the potential use of L. pentosus GMNL-77 in the future treatment of psoriasis. Copyright (C) 2016, Food and Drug Administration, Taiwan.
