The pro-inflammatory cytokine macrophage migration inhibitory factor (MIF) was also identified by Kwak et al. [21] as one of four biomarkers from a total of 21 blood biomarkers that could be used in a screening panel for sarcopenia with significantly higher levels in the sarcopenic participants (25.1 ± 1.19 vs. 20.71 ± 0.89 ng/mL, (p = 0.008)). Here, MIF is linked to sarcopenia.
