We, the Editors and Publisher of the journal Drug Design, Development and Therapy have retracted the published article.

After publication, concerns have been raised by a third party in 2025 regarding the integrity of the data in Figures 4 and 11 in the article.

Further investigations conducted by the Journal and Publisher confirmed the following:

• Figure 3 includes unexpected similarities between the image panels representative of different experimental conditions.
• Figure 4 includes unexpected similarities between the image panels representative of different experimental conditions.
• Unexpected similarities identified between the flow cytometry plots shown in Figure 7.
• Figure 11 includes overlapping images for samples representative of different experimental conditions.

When approached for an explanation, the authors requested the withdrawal of the article. As verifying the validity of published work is core to the integrity of the scholarly record, we are therefore retracting the article. The corresponding author listed in this publication has been informed.

We have been informed in our decision-making by our editorial policies and the COPE guidelines. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
