Figure Lengend Snippet: Increased IL-1β secretion by macrophages due to autophagy impairment enhances inflammatory chemokine expression in LSECs. ( A ) Protein expression in ATG7-KO macrophages and NC macrophages generated using the CRISPR-CAS9 system. ( B ) Evaluation of IL-1β and caspase-1 levels in the culture supernatant of THP-1 macrophages by ELISA following 24-hour stimulation with or without 25 ng/mL LPS (n = 3/group). ( C ) Experimental method using LPS-stimulated THP-1 macrophage conditioned medium. ( D ) Evaluation of NF-κB or MAP kinase-related proteins in TMNK-1 cells. ( E and F ) Inflammatory chemokine gene expression in TMNK-1 cells when treated with control medium or THP-1 macrophage conditioned medium (n = 4/group). SN50, NF-κB inhibitor; SP600125, JNK inhibitor; SB203580, p38 MAPK inhibitor. ( G ) Inflammatory chemokine gene expression measured 24 hours after treating TMNK-1 cells with varying concentrations of human recombinant IL-1β (n = 4/group). ( H ) Evaluation of inflammatory chemokine expression in TMNK-1 cells after 6 hours of stimulation with recombinant human IL-1β (5 ng/mL) in the presence of SP600125 and SB203580 (n = 4/group).
