Atheroprotective effects of methotrexate on reverse cholesterol transport proteins and foam cell transformation in human THP‐1 monocyte/macrophages

Abstract: Results. MTX increased 27-hydroxylase message and completely blocked NS398-induced down-regulation of 27-hydroxylase (mean ؎ SEM 112.8 ؎ 13.1% for NS398 plus MTX versus 71.1 ؎ 4.3% for NS398 alone; P < 0.01). MTX also negated COX-2 inhibitor-mediated down-regulation of ABCA1. The ability of MTX to reverse inhibitory effects on 27-hydroxylase and ABCA1 was blocked by the adenosine A 2A receptor-specific antagonist ZM241385. MTX also prevented NS398 and IFN␥ from increasing transformation of lipid-laden THP-1 ma… Show more

“…An atheroprotective effect of MTX through A 2A receptor activation, which is involved in the facilitation of cholesterol outflow, was recently reported (30). In RA patients, the overexpression of A 3 adenosine receptor has been directly correlated with high levels of proinflammatory cytokines acting via up-regulation of NF-B, the DNA binding sites of which are present in the promoter of the A 3 receptor gene (31,32).…”

“…Во-вторых, посредством активизации аденозинового рецептора А2а, МТ уве-личивает обратный транспорт холестерина и ограничи-вает образование пенистых клеток в артериальной стен-ке. При этом пути реализации протективных эффектов МТ отличаются от механизма действия статинов и ан-титромботических препаратов [17,18]. Таким образом, по влиянию на сердечно-сосудистую систему МТ яв-ляется эталоном среди противовоспалительных пре-паратов [19][20][21].…”

“…Our finding is counterintuitive, because MTX has antiinflammatory effects due to its capacity to release adenosine. This increases the expression of enzymes involved in metabolizing cholesterol and of transporters involved in the reverse transport of cholesterol 52 .…”
