Inhibition of fucosylation reshapes inflammatory macrophages and suppresses type II collagen-induced arthritis.

ABSTRACT:

Objective

Fucosylation catalyzed by fucosyltransferases (FUTs) is an important posttranslational modification involved in a variety of biologic processes. This study was undertaken to determine the roles of fucosylation in rheumatoid arthritis (RA) and to assess the efficacy of reestablishing immune homeostasis with the use of 2-deoxy-d-galactose (2-d-gal), a fucosylation inhibitor.

Methods

Quantitative polymerase chain reaction was performed to determine the expression of FUT genes in synovial tissue from RA and osteoarthritis (OA) patients and in fluorescence-activated cell-sorted cells from RA synovial fluid. The in vivo inhibitory effect of 2-d-gal was evaluated in a murine collagen-induced arthritis (CIA) model. The in vitro effects of 2-d-gal on differentiation of infl
