Formulated extract from multiple citrus peels impairs immune dendritic cells functions

and attenuates allergic contact hypersentivity

Gold lotion (GL), a formulated product made from the peels of citrus fruits, has many pharmacological activities, such as anti-tumor, antioxidant, and anti-inflammatory activities. In this study, we examine the immunomodulatory effect of GL on lipopolysacchride (LPS) stimulated mouse bone marrow-derived DCs maturation and function. Our experimental results show that GL significantly inhibited the pro-inflammatory cytokines and chemokine expression in LPS-induced DCs in a dose dependent manner. In addition, GL treatment led to inhibit the expression of of MHC and costimulatory molecules, influence the ability to take up antigen and attenuated allo-T cell activating ability of LPS stimaultaed DCs. Furthermore, oral administration of GL attenuates the 2,4-Dinitro-1-fluorobenzene induced contact hypersensitivit (CHS) in vivo. Consequently, molecular studies showed that GL decrease LPS-induced MAPK-ERK, p38 phosphrylation and nuclear translocation of NF-ƒΘB p65. Taken together, these findings provide new insight into the immunopharmacological role of GL and used to treat DC mediated-chronic inflammatory disorders or autoimmune diseases.
