Abstract
NK cells are an innate class of lymphocytes in the human body that can
achieve non-specific killing of tumor cells without MHC restriction or
prior sensitization. In recent years, targeted killing of tumor cells
has become possible due to the development of diverse biological
technology, particularly the chemical chimeric antigen receptors (CAR),
and other technologies. CAR gives NK cells a new magic, and its
extracellular domains of the recognition region are usually single-chain
antibodies (scFv), which can be targeted to specific antigens. CAR-NK
cells have shown excellent results in several preclinical studies and
clinical trials for hematologic malignancies. However, their clinical
application in the treatment of solid tumors is still insufficient.
Currently, the treatment of gynecological tumors relies mainly on
surgery, chemotherapy, and radiotherapy, which are often accompanied by
significant side effects and limited efficacy. CAR-T cell therapy has
shown efficacy in certain gynecological tumors. However, side effects
that are still urgent problems in clinical applications such as
Graft-Versus-Host Disease (GVHD) and Cytokine Release Syndrome (CRS)
have been observed. In contrast, CAR-NK cell therapy shows potential
advantages in this area. Based on the above, this review mainly focuses
on the development of CAR-NK cell constructs and their promising
applications for immunotherapy of gynecological malignancies, aiming to
provide references for clinical trials and clinical studies.
