Insights

Natural killer T (NKT) cells show promise for cancer immunotherapy. Artificial antigen-presenting cells (aAPCs) offer a standardized method to expand these cells for improved antitumor immunity.

Area of Science:

  • Immunology
  • Cell Biology
  • Cancer Research

Background:

  • Natural killer T (NKT) cells are crucial for antitumor immunity but are often reduced in cancer patients.
  • Ex vivo expansion of NKT cells with alpha-galactosylceramide (α-GalCer) and cytokines enhances their number and function for adoptive immunotherapy.

Purpose of the Study:

  • To review the progress and future potential of using artificial antigen-presenting cells (aAPCs) for NKT cell expansion.
  • To address limitations associated with autologous antigen-presenting cells in NKT cell-based immunotherapy.

Main Methods:

  • Discussion of CD1d-based aAPCs as an acellular antigen-presenting system.
  • Review of strategies for stimulating and expanding NKT cells using aAPCs.

Main Results:

  • Expanded NKT cells maintain their phenotype, responsiveness, and cytotoxic function against tumor cells.
  • Artificial antigen-presenting cells (aAPCs) provide a standardized alternative to dendritic cells, avoiding issues with cell quantity and quality.

Conclusions:

  • Ex vivo expanded NKT cells are a viable option for adoptive immunotherapy.
  • CD1d-based aAPCs represent a promising platform for advancing NKT cell biology research and developing targeted immunotherapeutic strategies.

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...
T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

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.
Naive T cells that have not yet encountered an antigen express two primary CD...

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
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...
