What are the precise molecular mechanisms by which ZBP1 recruits RIPK3 and caspase-8 upon Z-RNA sensing?

OPEN

The abstract states that ZBP1 recruits RIPK3 and caspase-8 when Z-RNA is sensed, but the specific molecular interactions and sequential steps in this recruitment process are not explained. Understanding these mechanisms is crucial for developing targeted therapeutic interventions for inflammatory diseases involving PANoptosis.
