Interestingly, in the ALCs of congenital cataract patients, all three TGFβ isoforms were positively correlated, but in traumatic cataract patients, there were only positive correlations between the mRNA levels of TGFβ1 and TGFβ2. Moreover, in the PBMCs of congenital cataract patients, only TGFβ1 and TGFβ2 exhibited positive association, whereas in the traumatic cataract patients, the TGFβ1 and TGFβ3 isoforms were correlated. Here, TGFB3 is linked to cataract.
