“…Current studies demonstrate that miR21 [85] , miR155 [63] , miR301a [86] , miR326 [87] , miR1792 cluster [88] , and miR132/212 cluster [89] act as positive regulators of Th17 differentiation. For example, miR155 enhances the development of inflammatory T cells (Th1 and Th17 cells), and facilitates Th17 cell formation through cytokines produced by DCs [63] .…”

“…miR-21 is known to be specifically expressed in the Treg subset (13) and promotes Treg differentiation by positively regulating expression of FoxP3 itself, the Treg-specific transcription factor. miR-21 also has the potential to positively regulate Treg activity by directly targeting a proposed negative regulator of TGF-β signaling, SMAD7 (14,15). In contrast, other studies have suggested that miR-21 in fact restrains Treg activity through intrinsic T-reg-specific mechanisms and limiting FOXP3 activity (16) or indirectly by promoting the activity of Th17 cells, whose pro-inflammatory nature counters Treg function (14).…”

With this in mind, Li and colleagues found that the decrease in TGF-β and FoxP3 expression in PBMC from diseased patients was consistent with a decrease in mRNA expression of the miR-21 target SMAD7.…”

“…L'expression de nombreux miARN, qui est altérée dans le SNC de patients atteints de SEP, l'est également dans le modèle murin d'EAE (miR-21 [15,36], miR-326 [11,15], miR-155 [12,15] Nous avons partagé jusqu'ici avec le lecteur une vision simplifiée de l'implication des lymphocytes T autoréactifs dans l'EAE. Le développement de l'EAE repose effectivement sur la différenciation de cellules Th17 et Th1 : les souris déficientes pour Rort (retinoic acid receptor-related orphan receptor gamma t, pour les cellules Th17) ou pour T-bet (T-box transcription factor, pour les Th1) sont résistantes à l'EAE [40,41].…”

“…Les miARN agissent en fait fréquem-ment sur la différenciation et/ou l'activation de ces cellules. Ainsi, lors de l'induction de l'EAE, la dérégulation de certains miARN (miR301a [39] [36] et Ets-1 [11]), favorise l'émergence des phénotypes Th17 ou Th1 (Figure 3). Ainsi, altérer l'expression de ces miARN au cours de l'EAE provoque une augmentation du nombre de lymphocytes T pro-inflammatoires de types Th17 et Th1, ce qui accentue sa sévérité.…”
