The paper on antibody diversity by corresponding author Andrea Cerutti, a professor at the Catalan Institution for Research and Advanced Studies in Spain, appeared in Nature Immunology in 2002. The retraction comes on the heels of another retraction for Cerrutti, also for a paper in Nature Immunology. Both had been flagged on PubPeer for image issues. The authors maintain there was no misconduct.

The most recent retraction notice, published Feb. 9, 2026, states three of the figures “appear to partially overlap” with or be “highly similar” to those in another of Cerutti’s papers published in The Journal of Immunology in 2002. Cerutti and his coauthor, Paolo Casali, agreed with the retraction, according to the notice. None of the other authors could be reached, the notice says.
