proteasome

pro·te·a·some

 (prō′tē-ə-sōm′)
n.
A cellular protein complex consisting of proteolytic enzymes that degrade endogenous proteins, especially those that are damaged, pathogenic, or no longer of use.
[Alteration of earlier prosome (influenced by protease) : pro(grammed), from the earlier belief that proteasomes played a role in regulating messenger RNA translation + -some.]

As other kinds of cells, RPE have a normally active UPP [17], and the activity of UPP decreases in different human tissues (including skin, muscle, kidney, liver, lung, heart, lentis, and RPE) with the increase of age [17, 31, 32], however, the relationship between the decline in proteasome activity in RPE and the production of inflammatory cytokine IL-6 which plays an important role in cell growth and inflammatory reactions [30, 33] remains to be obscured.
