Of the induced cytokines in eyes with BRVO, IL-8 was the most significantly associated with the disease parameters of BRVO. IL-12 is most likely a factor that blocks the effect of bevacizumab treatment. (www.umin.ac.jp/ctr number, UMIN000003854.).

HCECs respond to HSV-1 infection by initiating mitogen-activated protein kinase-related transcriptional events, and IL-6 may serve to induce expression of an array of inflammatory mediators.

Corneal endothelial cells transcriptionally initiate inflammatory programs in response to HSV-1 infection related to NF-κB, CRE, and C/EBP and express arrays of inflammatory cytokine induction by TLR9. On the other hand, HSV-1 exploits TLR9-mediated NF-κB activation for its own replication.

HCEn cells respond to HSV-1 infection by initiating antigen presentation-related inflammatory responses, and they may serve as antigen-presenting cells.

The significant associations between elevated levels of IL-23 with PCV and its activity strongly suggest an involvement of inflammatory processes in the etiology of PCV, presumably independent of VEGF. (www.umin.ac.jp/ctr number, UMIN000003854.).
