How does MLKL inhibition upregulate Nrf2 signaling independently of its necroptosis executor function?

OPEN

The study shows NSA reduces inflammation by upregulating Nrf2 pathways, but MLKL is considered the final executor of necroptosis, not a transcriptional regulator. The mechanism linking MLKL inhibition to Nrf2 activation remains unexplained and could reveal novel therapeutic targets.
