Age-related para-inflammation in the retina-choroidal interface is featured by
low-levels of complement activation and subretinal macrophage accumulation. This
study aimed to understand how complement expression in macrophages is regulated
by retinal pigment epithelium (RPE). Bone marrow-derived macrophages (BMDMs) and
RPE cells were cultured from 8-10 weeks old C57BL/6J mice. The BMDMs were
co-cultured with normal RPE, or oxidized photoreceptor outer segment (oxPOS) or
TNF-? pre-treated RPE, or apoptotic RPE, or RPE-choroid eyecups. Macrophages were
then isolated and processed for real-time RT-PCR. The expression of complement
inhibitor C1INH in BMDMs was significantly upregulated by RPE and RPE-choroid
eyecups. The eyecups also upregulated CFH, CD59a, and Crry in BMDMs. oxPOS
pre-treated RPE upregulated C1qb but down-regulated C3 expression in BMDMs. TNF-?
pre-treated RPE enhanced C1INH and CFB expression. When BMDMs were treated with
apoptotic RPE, the expression of C1qb, CFH, and CD59a was reduced, whereas the
expression of C3, CFB and C1INH was increased. Our results suggest that RPE can
modulate macrophages complement expression at the retina-choroidal interface even
under aging or oxidative conditions. However, during inflammation, they may
promote the alternative pathway of complement activation through down-regulating
CFH and CD59a and upregulating CFB and C3.
