Summary
Interleukin-13 receptor alpha 2 (IL-13Ralpha2) is more than a decoy receptor. New findings show IL-13Ralpha2 has complex roles in modulating immune responses.
Area of Science:
- Immunology
- Molecular Biology
- Cell Biology
Background:
- Interleukin-13 (IL-13) is a key cytokine in allergic inflammation, primarily secreted by T-helper type 2 (Th2) cells.
- IL-13 functions are mediated by a receptor system involving IL-4 receptor alpha (IL-4Ralpha) and IL-13Ralpha1 (a signaling component).
- IL-13Ralpha2 was traditionally considered a decoy receptor due to its short cytoplasmic tail.
Purpose of the Study:
- To review the different isoforms of IL-13Ralpha2.
- To discuss the newly revealed functions of IL-13Ralpha2 beyond its decoy role.
- To highlight the complex involvement of IL-13Ralpha2 in immune regulation.
Main Methods:
- Literature review of recent reports on IL-13Ralpha2.
- Analysis of studies investigating IL-13Ralpha2 expression (membrane, intracellular, soluble).
- Examination of evidence for IL-13Ralpha2 signaling capabilities and modulatory functions.
Main Results:
- IL-13Ralpha2 exists in multiple forms: membrane-bound, intracellular, and soluble.
- Emerging evidence suggests membrane IL-13Ralpha2 possesses signaling capabilities.
- Soluble IL-13Ralpha2 acts as a critical endogenous modulator of IL-13-mediated responses.
Conclusions:
- IL-13Ralpha2 exhibits more complex functions than previously understood.
- The receptor's roles extend beyond simple decoy activity, influencing immune responses.
- Further research into IL-13Ralpha2 isoforms and functions is warranted.

01:21G-protein Coupled Receptors
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

01:12GPCR Desensitization
G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...
01:10Integrins
Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:30Transducer Mechanism: G Protein–Coupled Receptors
G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical, 7TM, or...

01:30Spare Receptors
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...
