Differential effects of SARS-CoV-2 infection on THP-1 cells and CaLu-3. a Bar graph showing IL-1β release levels of THP-1 cells after 24 h from SARS-CoV-2 infection (n = 6) or LPS + BzATP stimulation (n = 3) compared to untreated cells (n = 4). b Bar graph showing IL-1β release levels of CaLu-3 cells after 24 h from SARS-CoV-2 infection (n = 3) or LPS + BzATP stimulation (n = 3) compared to untreated cells (n = 4). c Bar graph showing SARS-CoV-2 genomes in CaLu-3 cells at 8- and 24 h post-infection (h p.i.) (n = 2). d Bar graph showing IL-6 levels in THP-1 cells after 24 h from SARS-CoV-2 infection (n = 4) or LPS + BzATP stimulation (n = 2) compared to untreated cells (n = 3). ns = not significant, ** = p < 0,01, *** = p < 0,001
