Dual-specificity phosphatase 2 (Dusp2; also called phosphatase of activated cells
1, PAC1) is highly expressed in activated immune cells. We examined whether a
potential inhibitor of Dusp2, salubrinal, prevents inflammatory cytokine
expression in immune cells and arthritic responses in a mouse model of
anti-collagen antibody-induced arthritis (CAIA). Salubrinal is a synthetic
chemical that inhibits de-phosphorylation of eukaryotic translation initiation
factor 2 alpha (eIF2?). In this study, we examined the effects of salubrinal on
expression of inflammation linked genes as well as a family of DUSP genes using
genome-wide microarrays, qPCR, and RNA interference. We also evaluated the
effects of salubrinal on arthritic responses in CAIA mice using clinical and
histological scores. The results revealed that salubrinal decreased inflammatory
gene expression in macrophages, T lymphocytes, and mast cells. Dusp2 was
suppressed by salubrinal in LPS-activated macrophages as well as
PMA/ionomycin-activated T lymphocytes and mast cells. Furthermore, a partial
silencing of Dusp2 downregulated IL1? and Cox2, and the inflammatory signs of
CAIA mice were significantly suppressed by salubrinal. Collectively, this study
presents a novel therapeutic possibility of salubrinal for inflammatory arthritis
such as RA through inhibition of Dusp2.
