IL6 and Alzheimer disease: AD-MSC-Exos (human abdomen-derived adipose tissue) express miR-93-5p, which targets disintegrin and metalloproteinase with thrombospondin motifs 9 (ADAMTS9), hence reducing autophagy and apoptosis, and targeting inflammatory factors like IL-1β, TNF-α, IL-6, and iNOS [140].
