Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Purpose. C5a anaphylatoxin is a potent inflammatory mediator that acts on polymorphonuclear cells (PMN) and monocytes via C5a receptors (C5aR). It mediates chemotaxis of both cell types and stimulates cytokine release from the latter. To investigate whether C5a can act on retinal pigment epithelial (RPE) cells, we examined ARPE-19 cells for the presence of C5aR and the effect of C5a stimulation. Methods. C5aR expression was measured by flow cytometry using specific anti-C5aR antibody and by RT-PCR analyses. Cells were stimulated with 50 nM C5a and the induction of IL-8 mRNA expression was measured by semi-quantitative RT-PCR. Results. Surface levels of C5aR on ARPE-19 cells were found to be comparable to those on human PMN. Stimulation with C5a induced a dose- and time-dependent increase of IL-8 mRNA expression. Conclusion. The findings of C5aR on ARPE-19 cells and induction of IL-8 mRNA upon C5a stimulation suggests that C5a may participate in the defense of choroidal and retinal tissue during inflammation.
