TAGLN2 and neoplasm: Immunophenotyping analyses conducted 7 days after the second T cell infusion (day 21 of tumor development) demonstrated that CER-Tagln2 T cells infiltrating the omentum and peritoneal cavity maintained high TAGLN2 expression, while unmodified CER T cells present at the same tumor sites exhibited minimal production of this cytoskeletal element (Fig. 6g).
