Insights

The carcinoembryonic-antigen-related cell-adhesion molecule (CEACAM) family, especially CEACAM1, plays a key role in regulating immune responses during infection, inflammation, and cancer. These proteins influence cell adhesion and signaling, impacting both normal and cancerous cell growth.

Area of Science:

  • Immunology
  • Cell Biology
  • Molecular Biology

Background:

  • The carcinoembryonic-antigen-related cell-adhesion molecule (CEACAM) protein family is involved in cell adhesion and intracellular signaling.
  • CEACAMs influence the growth and differentiation of normal and cancerous cells.
  • Emerging evidence highlights CEACAMs' role in modulating immune responses.

Purpose of the Study:

  • To review the involvement of CEACAM family members in immunity.
  • To emphasize the specific role of CEACAM1 as a regulatory co-receptor.
  • To explore CEACAM functions in the context of infection, inflammation, and cancer.

Main Methods:

  • Literature review of recent studies on CEACAMs and immunity.
  • Analysis of CEACAM1's function as a co-receptor in lymphoid and myeloid cells.
  • Synthesis of evidence linking CEACAMs to immune modulation.

Main Results:

  • CEACAM family members are implicated in diverse immune responses.
  • CEACAM1 acts as a crucial regulatory co-receptor for immune cells.
  • CEACAMs influence immune surveillance and response in cancer, infection, and inflammation.

Conclusions:

  • CEACAMs are significant regulators of immune cell function.
  • CEACAM1 is a key player in immune modulation across various conditions.
  • Understanding CEACAMs offers potential therapeutic targets for immune-related diseases.

Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

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 possess both immunogenicity and reactivity.
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
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...
Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

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...
