WCS exposure attenuated HBD-1 secretion and enhanced HBD-2 secretion by Leuk-l cells. Compared with the basal secretion level in control group, 10 min-, 20 min- and 40 min-WCS exposure induced significant down-regulation of HBD-1 secretion by Leuk-1 cells. Compared with the basal secretion level in control group, 20 min- and 40 min-WCS exposure significantly enhanced HBD-2 secretion by Leuk-1 cells. There was no significant difference of HBD-3 secretion between WCS exposure groups and control group. ELISA data were expressed as means ± SE (n = 12/group). Statistical significance: *P < 0.05, vs. control; **P < 0.01, vs. control.
