The research literature reports a favourable safety profile with few side effects at therapeutic doses
evidence that selenoproteins may be encoded in the +1 reading frame overlapping the human Cd4, Cd8, and hla-Dr genes
These cells secrete proinflammatory cytokines, including IFN-, IL-1, IL-12, CCL4, CCL5, and GM-CSF, which are associated with hepatocyte damage, increased ROS production, apoptosis, and activation of JAK-STAT1/3 and NF-B signaling pathways ( in vitro evidence suggests that NK cells may exert anti-fibrotic effects by eliminating activated HSCs through NKp46/NCR1-dependent, RAE1/NKG2D-dependent, and TRAIL-dependent mechanisms ( Figure 5A )
