Concentrations of inflammatory biomarkers [interleukin (IL)-1 and tumor necrosis factor (TNF)] elaborated by conjunctival epithelial cells (CCC: Wong-Kilbourne derivative of conjunctiva) after being put in contact with varying concentrations of each of the follow-up experimental testing solutions [media alone, benzalkonium chloride (BAK: 0.1%, 0.02%, 0.002%), and lypopolysaccharide (LPS: 100 ng/mL, 10 ng/mL) for 1 h, the solutions replaced with media and then incubated for 23 h.
