An increase of oxidized coenzyme Q-10 occurs in the plasma of sporadic ALS patients.

Abstract:

:We have compared plasma redox status of coenzyme Q-10 in 20 sporadic amyotrophic lateral sclerosis (sALS) patients with those in 20 healthy age/sex-matched controls. A significant increase in the oxidized form of coenzyme Q-10 (sALS=109.3+/-95.2 nM; controls=23.3+/-7.5 nM, P=0.0002) and in the ratio of oxidized form of coenzyme Q-10 to total coenzyme Q-10 (%CoQ-10) (sALS=12.0+/-9.3%; controls=3.2+/-0.9%, P<0.0001) were observed. Moreover, %CoQ-10 correlated significantly with the duration of illness (rho=0.494, P=0.0315). Our finding suggests systemic oxidative stress in the pathogenesis of sALS.

  • Expression of 3G11 epitope defines subpopulations of regulatory T cells with different suppressive potency.

    abstract::3G11, a sialylated carbohydrate epitope on the disialoganglioside molecule, is expressed predominantly on the surface of mouse CD4(+) T cells. Our previous studies suggested that lack of the 3G11 molecule could be a new cell surface marker for regulatory CD4(+) T cells. In the present study, we explore the relationshi...
