3.3 Gene expression of fibrotic, apoptotic and inflammation marker in the conjunctival cells
The mRNA expression of IL6, vimentin and Bcl2/Bax were evaluated. The conjunctival IL6 expression was increased by 2-fold though not statistically significant indicating a pro-inflammatory status in VKC. Bcl2/Bax ratio was down regulated, however; vimentin was found to be significantly upregulated in VKC cases compared to control(Figure 2C) .
