Recent advances have improved our understanding of natural killer (NK) cell-mediated alloreactivity after hematopoietic cell transplantation (HCT) or with adoptive transfer. NK cells contribute to a graft-versus-leukemia effect and may play a role in preventing graft-versus-host disease or controlling infectious diseases after allogeneic HCT. New discoveries in NK cell biology, including characterization of NK cell receptors and their interactions with self-HLA molecules and a better understanding of the mechanism of NK cell education have led to the development of novel strategies to exploit NK cell alloreactivity against tumors. While early studies using autologous NK cells lacked efficacy, the use of adoptively transferred NK cells to treat hematopoietic malignancies has been expanding. The production of allogeneic donor NK cells requires efficient removal of T- and B cells from clinical-scale leukapheresis collections. The goal of this chapter is to review NK cell biology, NK cell receptors, the use of NK cells as therapy and then to discuss the clinical decisions resulting in our current good manufacturing practices processing and activation of human NK cells for therapeutic use.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Cells of the Innate Immune Response01:28

Cells of the Innate Immune Response

The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Immune Surveillance by NK Cells and Phagocytes

Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

NK cells are large granular lymphocytes found in the blood and lymphatic system. These...
