Exosomes/miRNA definitely have a big role in melanin production. In a recent study, researchers found that miRNA secreted by keratinocyte derived exosomes had a role in regulating melanogenesis. Specifically, miR-330-5p was produced by keratinocyte derived exosomes. The exosomes with increased expression of miR-330-5p caused an increase in miR-330-5p in melanocytes which resulted in reduced melanin production. (https://www.sciencedirect.com/science/article/pii/S0923181119300271) On the other hand, you have miR-379 which promotes pigmentation. miR‐379 is highly expressed in alpaca melanocytes which leads to increased melanogenesis and proliferation by targeting the insulin‐like growth factor 1 receptor. (https://onlinelibrary.wiley.com/doi/abs/10.1111/exd.14095) These are just examples of how miRNA can positively or negatively impact pigmentation. ...
