LRRFIP1 and viral infectious disease: It would be interesting to address whether BCAP is required for the negative regulation of the NLRP1 inflammasome of HSPCs by LRRFIP1/FLII and the relevance of LRRFIP1 and FLII in the regulation of NLRP1 inflammasome in other cell types, such as keratinocytes, especially after their activation by UV‐induced ribotoxic stress response and viral infection, which are independent of DPP9.
