Dear Dr. Bik,
I’m writing to you in response to recent inquiries you posted with regard to mentioned studies conducted at the National Key Laboratory of Medical Immunology and Institute of Immunology at the Second Military Medical University, with me being the corresponding author.
I appreciate your interest in our work and your commitment to protecting the accuracy of scientific records and the integrity of research pursuit. They are of utmost importance to me all along as well. Upon being notified of your inquiries, I have made them our highest priority and immediately took steps to look into the concerns you raised with the team and collaborators and carefully re-examined our manuscripts and raw data and lab records. We’ll work with the relevant journal editorial office(s) immediately if our investigation indicates any risk to the highest degree of accuracy of the published records.
Based on our analyses up to this point (still ongoing) and additional feedback we received from colleagues and peers, I would like to add that I remain confident about the validity and strength of the scientific conclusions made in those publications and our work’s reproducibility. Nevertheless, there is no excuse for any lapse in supervision or laboratory leadership and the concerns you raised serve as a fresh reminder to me just how important my role and responsibility are as mentor, supervisor, and lab leader; and how I might have fallen short. I feel therefore very heavy-hearted and tremendously sorry, to my current and former students, my staff and colleagues, my peers, and the larger community. I most sincerely apologize for any oversight on my part and any inconvenience it might have caused. I’ll use this as an invaluable learning opportunity to do better not only in advancing science, but also in safeguarding the accuracy and integrity of science.
