Hypothesis
To understand the expression of genes involved in different complement pathways in the retina and retinal pigment epithelium/choroid under physiologic conditions and how their expression is regulated by inflammatory cytokines.
Conclusion
Retina and RPE/choroid express a variety of complement components that are involved mainly in the classical and alternative pathways, regulated by inflammatory cytokines.
Supporting Evidence
- Complement components of the classical pathway were constitutively expressed in the retina and RPE/choroid.
- Inflammatory cytokines like IFN-γ and TNF-α regulated the expression of complement genes.
- Microglial and RPE cells were identified as the main sources of retinal complement gene expression.
Takeaway
The study found that certain genes related to the immune system are active in the eye, and their activity can change when the eye is inflamed.
Methodology
Gene expression was analyzed using reverse transcription polymerase chain reaction (RT-PCR) and real-time RT-PCR in mouse retina and RPE/choroid tissues.
Participant Demographics
