Research Abstract

Balb/c mice were immunized with ragweed in alum. Ten days later, the mice were challenged with ragweed in eye drops to induce allergic conjunctivitis. Twenty-four hours after the challenge, conjunctivas were harvested to extract RNA. As a control, conjunctivas were collected from immunized mice just prior to ragweed challenge. Expression of miRNA were compared between the two groups by using microarray analysis. Forty-four miRNAS were identified to be downregulated to be less than half by induction of conjunctivitits, while 74 miRNAS were identified to be upregulated to be more than 2-fold by induction of conjunctivitis.
Combined evaluation identified the target genes of miRNAS such as Lrp2 binding protein and lactoperoxidase.
