Perilipin 2 (PLIN2), which positively correlates with hepatic steatosis (Chang et al., 2006; Fukushima et al., 2005; Motomura et al., 2006; Najt et al., 2016), is one of the best-characterized LD proteins associated with fatty liver disease (Okumura, 2011). Here, PLIN2 is linked to fatty liver disease.
