ABSTRACT
<p><b>BACKGROUND</b>Anterior chamber associated immune deviation (ACAID) is characterized by a Th2 cell response. GATA-3 has been shown to be necessary for the activation of Th2 cells. This study was designed to examine the expression of GATA-3 in the development of ACAID.</p><p><b>METHODS</b>ACAID was induced by injection of 50 microg interphotoreceptor retinoid binding protein (IRBP) into the anterior chamber (AC) of Wistar rats. Delayed-type hypersensitivity (DTH) was evaluated on day 3, 7, 14, 21, 28 after IRBP inoculation. GATA-3 expression was detected using immunohistochemical staining. The expression of GATA-3 mRNA at different time points after AC injection of IRBP was assayed by reverse transcriptase polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>A significant DTH reaction was observed in Wistar rats on day 3 and 5 after IRBP inoculation. The DTH reaction was decreased 7 days after IRBP inoculation. GATA-3 expression was weak at both mRNA and protein levels in the normal spleen, but was significantly increased on day 5, 7, 14, and 21 after AC injection of IRBP.</p><p><b>CONCLUSION</b>The expression of GATA-3 is increased during ACAID, suggesting that GATA-3 may be involved in the development of ACAID.</p>
