Summary
This study on Toll-like receptor 4 (TLR4) was retracted due to concerns about flow cytometry data integrity. The editor lost confidence in the presented results, and authors did not respond to inquiries.
Area of Science:
- Immunology
- Cell Biology
Background:
- A previously published study in Molecular Medicine Reports investigated Toll-like receptor 4 (TLR4) signaling.
- Concerns were raised regarding the reproducibility and integrity of specific experimental data presented in the paper.
Purpose of the Study:
- To address potential data irregularities identified in flow cytometry plots.
- To evaluate the validity of the presented experimental findings.
Main Methods:
- Review of flow cytometry data presented in Figure 3A.
- Assessment of experimental conditions and data output for 'anti-TLR4+LPS' and 'TLR4-shRNA+LPS' experiments.
Main Results:
- Flow cytometry plots for different experimental conditions appeared unexpectedly similar.
- This similarity suggested potential flaws in experimental execution or data presentation.
Conclusions:
- The study has been retracted due to a lack of confidence in the presented data.
- The findings raise concerns about the reliability of the research conclusions.
- Authors did not provide a satisfactory explanation for the observed data discrepancies.
