SHANGHAI, March 26, 2025 /PRNewswire/ — Shanghai Juncell Therapeutics Co., Ltd. (Juncell Therapeutics), a clinical-stage biotech developing innovative IL-2-independent Tumor-Infiltrating Lymphocyte (TIL) therapies for cancers, announced that a preclinical study of innovative pretreatment regimens for cell therapy will be presented at the American Association for Cancer Research (AACR) Annual Meeting, taking place April 25 – 30 in Chicago.
This study indicated that hydroxychloroquine (HCQ) could significantly increase the tumor-killing effects via elevating the membrane MHC-I protein levels of tumor cells without affecting TILs’proliferation. In addition, its effect on surface PD-L1 expression was not significant compared with IFN-γ. These results provide preclinical evidence for HCQ pretreatment of the adoptive cell therapy of TILs in clinical trials.
