NLRP3 and myocarditis: In a murine CVB3-induced myocarditis model, MSCs have been described to increase circulating Treg cells [90], modulate monocyte trafficking [9], and inhibit activation of nucleotide oligomerization domain (NOD)-, leucine-rich repeat (LRR)- and pyrin domain containing protein 3 (NLRP3) [91] among other cardioprotective effects.
