Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

2.1K
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...

Receptor-mediated Endocytosis

10.2K
Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

Spare Receptors

4.9K
Some receptors remain unoccupied even when an agonist produces a maximal response. Such empty ones are called spare receptors. In presence of spare receptors the maximum effect of an agonist drug is achieved with fewer than 100% of the receptors being occupied. To determine the presence of spare receptors, scientists often compare the concentration of the drug needed to produce 50% of the maximum effect (EC50) with the concentration of the drug needed to occupy 50% of the receptors (Kd). If the...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Summary

A new standardized nomenclature for scavenger receptors was proposed to clarify their diverse roles in immunity and cellular processes. This aims to reduce confusion caused by multiple names for these important myeloid cell receptors.

Area of Science:

  • Immunology
  • Cell Biology
  • Molecular Biology

Background:

  • Scavenger receptors (SRs) are a diverse protein family primarily on myeloid cells.
  • They recognize various ligands, including pathogens and altered self-molecules.
  • Existing nomenclature is inconsistent, causing literature confusion.

Purpose of the Study:

  • To establish a clear definition and standardized nomenclature for mammalian scavenger receptors.
  • To propose a classification system for scavenger receptors.
  • To solicit feedback from the research community on proposed nomenclature.

Main Methods:

  • A workshop convened by the National Institute of Allergy and Infectious Diseases (NIAID).
  • Discussions among 15 experts in the scavenger receptor field.
  • Consensus reached on a definition and proposed nomenclature.

Main Results:

  • Scavenger receptors defined as cell surface receptors binding multiple ligands to remove non-self or altered-self targets.
  • Proposed classification into 10 distinct classes.
  • Recommendations for standardized nomenclature presented.

Conclusions:

  • The proposed nomenclature and classification aim to unify understanding of scavenger receptor functions.
  • Standardization will facilitate research and communication in the field.
  • Further community feedback is encouraged for refinement.
