| Purpose: | The purpose of the experiment was to examine the effect of TNF-alpha on eosinophil longevity and which receptor of TNF-alpha is mediating the effect. | ||||
| Conclusion: | Our results suggest that TNF-alpha delays human eosinophil apoptosis via TNF-receptor 1. | ||||
| Comments: | Percentages of viable cells (Annexin-negative, PI-negative; lower left gate) are reported below each plot. Percentage of apoptotic cells may be calculated by summing upper left and upper right gates (Annexin V-positive population). | ||||
| Funding: | This study was supported by grants obtained from Tampere Tuberculosis Foundation (Tampere, Finland), the Finnish Anti-Tuberculosis Association Foundation (Helsinki, Finland), and the Competitive Research Funding of Seinäjoki Central Hospital and Tampere University Hospital (Grants VTR15, EVO1115, 9N023, 9M059, 9K048 and 9H031). The funders had no role in study design, data collection and analysis, decision to publish, or preparation of manuscript. | ||||
| Quality control: | We used IL-5-treated cells as a positive control for cell survival. | ||||
