(D) Bubble plots showing the expression of specific ligand-receptor pairs in the interaction between TEC subsets and myeloid cell subsets. (E, F) WT/AMPKα1 −/− BMDMs were treated with IL-4 and IL-13, and the expression levels of Arg 1 , Mmp12 , and Tnfsf12 were analyzed by qPCR (n = 5). (G, H) TCMK-1 cells were treated with CM from IL-4 and IL-13-stimulated WT/AMPKα1 −/− BMDMs. The expression of Pdgfb , Cxcl1 , and Egfr in TCMK-1 cells was analyzed by qPCR (n = 5). (I, J) TCMK-1 cells were treated with CM from IL-4 and IL-13-stimulated WT/AMPKα1 −/− BMDMs or together with recombinant TWEAK (rTWEAK). The expression of Pdgfb in TCMK-1 cells was analyzed by qPCR (n = 5). (K, L) TCMK-1 cells were treated with rTWEAK or rTWEAK and an Fn14 inhibitor. The expression of Pdgfb in TCMK-1 cells was detected by qPCR (n = 5). (M) Immunoblots and quantification of IKK-β and nuclear NF-κB p65 in TCMK-1 cells treated with PBS or rTWEAK (n = 3).
