Summary
Cell surface glycoRNAs, RNA-glycan conjugates, challenge RNA
Area of Science:
- Immunology
- Molecular Biology
- Glycobiology
Background:
- Cell surface glycoRNAs are novel RNA-glycan conjugates.
- They challenge the traditional view of RNA being solely intracellular.
- These molecules are displayed on the plasma membrane's outer leaflet.
Purpose of the Study:
- To summarize current knowledge on glycoRNA molecular features.
- To explore glycoRNA interfaces with immune receptors.
- To discuss glycoRNAs as a new layer of cell surface immune regulation.
Main Methods:
- Literature review of recent studies on glycoRNAs.
- Analysis of glycoRNA interactions with immune receptors.
- Discussion of glycoRNA's role in immune responses.
Main Results:
- GlycoRNAs are small noncoding RNAs with N- or O-linked glycans.
- They interact with immune receptors like P-selectin, Siglecs, TLRs, and lectins.
- GlycoRNAs influence neutrophil trafficking, immune activation, and tolerance.
Conclusions:
- GlycoRNAs represent a unique molecular interface on the cell surface.
- They engage multiple immune receptor families.
- GlycoRNAs may offer a new paradigm for cell surface immune regulation.

Diversity of Antigen Receptors
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...

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...

Surface Membrane Barriers
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
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.

RNA Interference
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
