LRRC8A and neoplasm: We investigated the role of the intermediate-conductance, Ca2+-activated K+ channel KCa3.1 and volume-regulatory anion channel LRRC8A in regulating C-C motif chemokine ligand 2 (CCL2) expression in THP-1-differentiated M2 macrophages (M2-MACs), which serve as a useful model for studying tumor-associated macrophages (TAMs).
