Summary
Chimeric antigen receptor (CAR) natural killer (NK) cells offer a promising off-the-shelf therapy for blood cancers. A phase I/II trial is evaluating a CAR NK-cell therapy targeting CD19 in hematologic malignancies.
Area of Science:
- Immunotherapy
- Cellular Therapy
- Hematologic Malignancies
Background:
- Natural killer (NK) cells are being explored for cancer therapy due to their inherent safety profile.
- NK cells do not cause graft-versus-host disease, enabling allogeneic, "off-the-shelf" applications.
- Chimeric antigen receptor (CAR) technology enhances immune cell targeting capabilities.
Purpose of the Study:
- To evaluate the safety and feasibility of a CAR NK-cell therapy.
- To assess the potential of CAR NK cells in treating hematologic malignancies.
Main Methods:
- Development of a CAR construct for NK cells.
- Preclinical testing of CAR NK cells.
- Initiation of a phase I/II clinical trial.
Main Results:
- Promising preclinical data supports the advancement of CAR NK-cell therapy.
- A phase I/II trial is currently underway.
Conclusions:
- CAR NK-cell therapy represents a viable strategy for hematologic malignancies.
- The off-the-shelf potential of CAR NK cells could revolutionize cancer treatment.

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
