Summary
Dendritic cells derived from acute myeloid leukemia (AML) cells can present leukemia antigens to T cells, potentially offering an anti-leukemia effect. These cells are explored for immunotherapy by loading them with antigens for therapeutic infusion.
Area of Science:
- Immunology
- Hematology
- Oncology
Context:
- Acute myeloid leukemia (AML) involves malignant hematopoietic stem cells.
- Dendritic cells (DCs) are crucial antigen-presenting cells in immune responses.
- DCs can be generated from both normal precursors and leukemia cells in AML patients.
Purpose:
- To review the role and therapeutic potential of dendritic cells in acute myeloid leukemia (AML) immunotherapy.
- To explore how DCs capture and present leukemia antigens.
- To discuss the use of engineered DCs for AML treatment.
Summary:
- Dendritic cells (DCs) in acute myeloid leukemia (AML) patients can originate from both normal and malignant cells.
- These DCs can capture leukemia antigens and present them to CD8(+) T cells, potentially mediating an anti-leukemia effect.
- DCs transformed from leukemia or peripheral blood cells and loaded with antigens are investigated for therapeutic reinfusion in AML.
Impact:
- Highlights the potential of dendritic cell-based immunotherapy for acute myeloid leukemia.
- Suggests a strategy for harnessing the immune system against leukemia.
- Provides a review of current understanding and future directions in DC-based AML treatment.

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

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.
