Summary
Natural killer (NK) cells are crucial for immunity and transplantation. This review details their development from hematopoietic stem cells (HSCs) to lineage-committed NK cells in mice.
Area of Science:
- Immunology
- Hematology
- Developmental Biology
Background:
- Natural killer (NK) cells are large granular lymphocytes integral to the innate immune system.
- NK cells play vital roles in combating infections, cancer, pregnancy, autoimmunity, and allergies.
- They are critical in hematopoietic stem cell (HSC) transplantation, mediating graft-versus-leukemia effects and preventing graft-versus-host disease.
Purpose of the Study:
- To review the developmental pathways of NK cells from multipotent HSCs to lineage-restricted progenitors.
- To highlight the clinical significance of understanding NK cell development.
- To address the less-established early stages of NK cell lineage commitment and development.
Main Methods:
- Review of existing literature on NK cell development.
- Analysis of progress in dissecting developmental stages from HSCs to NK cells.
- Focus on studies conducted in mouse models.
Main Results:
- Significant progress has been made in understanding mature blood cell development, including B and T cell lineages.
- The early stages of NK cell lineage commitment and development remain less well-characterized compared to other lineages.
- This review consolidates current knowledge on the developmental trajectory of NK cells from HSCs in the bone marrow.
Conclusions:
- Understanding NK cell development is of significant clinical value, particularly for HSC transplantation.
- Further research is needed to fully elucidate the early stages of NK cell lineage commitment.
- This review provides a comprehensive overview of the current understanding of NK cell development in mice.

01:27Cytotoxic 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...

01:28Cells 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...

01:25Immune 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.

01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
