NLRP3 and breast cancer: In this study, we showed that CAV1 increases the likelihood that BC lung metastasis would occur by controlling the expression of integrin α6β4 and via boosting TANs recruitment and polarization through activating the TLR4-NF-B-IL-6/CCL2 and TLR4/NF-B/NLRP3 signaling pathways.
