Abstract

Background: The KW-2449 is a novel multikinase inhibitor that inhibits FLT3, ABL, ABL-T315I, and Aurora A. FLT3 and Aurora A kinases play an important role in the pathogenesis of multiple sclerosis (MS). KW-2449 could modulate immune cells, but the immunomodulatory effects of KW-2449 on experimental autoimmune encephalomyelitis (EAE) have not been investigated yet. The aim of the present study is to investigate the effects of KW-2449 on EAE mouse model.

Methods: In this study, C57BL/6 EAE mice were orally treated with (10 mg/kg/day) KW-2449 solution and compared with EAE and control mice. Following the treatment, histological analyses were performed on the brain and cerebellum to evaluate the pathological score. The gene expression levels of tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), and chemokine (C-C motif) ligand 2 (CCL2) were measured using qRT-PCR. The serum levels of TNF-α, IL-6, CCL-2 and MMP-2 were determined by using quantitative enzyme-linked immunosorbent assay (ELISA).

Results: The results indicated that the clinical score, the infiltration of inflammatory cells and the demyelination in EAE mice treated with KW-2449 decreased significantly compared to control groups. KW-2449 also decreased TNF-α, IL-6, CCL-2 inflammatory cytokines, and MMP-2 in both brain mRNA expressions and serum levels of EAE mice.

Conclusion: The KW-2449, aging as a multi-kinase inhibitor, modulates the inflammatory responses of cytokine cascades either in the brain or in plasma and reduces EAE pathogenesis manifestation.

Keywords: Experimental autoimmune encephalomyelitis, KW-2449, Multiple sclerosis, TNF-α, IL-6, CCL-2, MMP-2.
