Altered expression of intracellular Toll-like receptors in peripheral blood mononuclear cells from patients with alopecia areata.

ABSTRACT:

Background

Toll-like receptors (TLRs) are pattern-recognition-receptors that sense a variety of pathogens and initiation of innate and adaptive immune responses. This study was undertaken to investigate the expression of TLRs in peripheral blood-mononuclear cells (PBMCs) of AA patients and to determine whether TLR-mediated inflammatory signals are important for the perspective of AA management.

Methods

Gene expression of TLRs and T-helper (Th) type-1, Th-2, Th-17 and regulatory T-cell cytokines in PBMCs was quantified by TaqMan Assays. Production of these cytokines in serum samples was determined by sandwich ELISAs.

Results

All TLRs (TLRs 1-10) were expressed in PBMCs of AA patients. Importantly intracellular TLRs (TLRs 3, 7, 8 and 9) were significantly up-regulated i
