Antigens Involved in Adaptive Immunity

476
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.

Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

543
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

B Cell Activation and Differentiation01:24

B Cell Activation and Differentiation

1.7K
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

861
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...

Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

3.2K
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...

Summary
This summary is machine-generated.

Chemerin, a protein involved in immune responses, acts as an adipokine and angiogenetic factor. Its activity is regulated by gene expression, protein processing, and receptor interactions, influencing immune cell function.

Area of Science:

  • Immunology
  • Endocrinology
  • Cell Biology

Background:

  • Chemerin, a cystatin family member, functions as a chemotactic, adipogenic, and angiogenic factor.
  • Its biological activity is modulated by gene expression, protein processing, and receptor binding.
  • Chemerin is produced by stromal cells and circulates as an inactive zymogen requiring activation.

Purpose of the Study:

  • To review the role of chemerin in regulating immune responses.
  • To explore chemerin's interactions with its receptors and their impact on immune cells.

Main Methods:

  • Literature review of studies on chemerin's biological functions and immune system regulation.
  • Analysis of chemerin's interactions with Chemerin1 (ChemR23/CMKLR1), GPR1, and CCRL2 receptors.

Main Results:

  • Chemerin binds to Chemerin1 (ChemR23/CMKLR1) on innate immune cells like macrophages and dendritic cells.
  • Chemerin also interacts with GPR1 and CCRL2 receptors on barrier cells, influencing leukocyte migration.
  • Chemerin's activation and receptor binding are critical for its biological functions in immunity.

Conclusions:

  • Chemerin plays a significant role in regulating immune responses through interactions with various receptors.
  • Understanding chemerin's functions is crucial for developing novel therapeutic strategies targeting immune-related diseases.
