    Abstract:

    AIM: To evaluate the early expression of mannose-binding lectin 2 (MBL2) in human corneal epithelial cells (HCECs) infected by Aspergillus fumigatus (AF). METHODS: HCECs cultured in vitro with AF antigens and sampled at 0, 0.5, 1, 2, 4, 6 and 8h. The expression of MBL2 mRNA was evaluated by semiquantitative reverse transcription-polymerase chain reaction (RT-PCR). The expression of MBL2 protein in supernatant fluid was shown by enzyme linked immunosorbent assay (ELISA). MBL2 protein in HCECs was detected by immunocytochemistry at 0 and 24h. RESULTS: MBL2 mRNA and protein are expressed in normal HCECs. The expression of MBL2 mRNA and protein in supernatant fluid begin to increase after being stimulated with AF antigens. The most significantly peak of MBL2 mRNA is in 2h. The protein of MBL2 in supernatant fluid decrease gradually after 0.5h. The protein in HCECs expression increase after stimulation of 24h. CONCLUSION: MBL2 receptor expressed in normal HCECs in vitro. The stimulation by AF antigens can increase the early expression of it.
