Summary
Atypical chemokine receptors (ACRs) are unique cell surface receptors that, unlike typical GPCRs, do not signal directly. They critically regulate chemokine function, impacting health and disease processes.
Area of Science:
- Immunology
- Cell Biology
- Biochemistry
Background:
- Atypical chemokine receptors (ACRs) are structurally similar to G-protein coupled receptors (GPCRs) but lack canonical signaling pathways.
- Despite lacking direct signaling, ACRs play crucial roles in modulating chemokine availability and function.
- These receptors are increasingly recognized for their involvement in various pathophysiological conditions.
Purpose of the Study:
- To review the characteristics of known ACRs, comparing their similarities and differences.
- To establish a cohesive understanding of ACR group identity.
- To summarize current knowledge on ACR expression, functions, and disease contributions.
Main Methods:
- Literature review of ACR research.
- Comparative analysis of individual ACR properties.
- Synthesis of data on ACR expression patterns, in vitro and in vivo functions, and disease relevance.
Main Results:
- ACRs exhibit diverse expression profiles across different cell types and tissues.
- ACRs function primarily as regulators of chemokine gradients and bioavailability.
- Evidence highlights ACR involvement in inflammatory diseases, cancer, and other pathologies.
Conclusions:
- ACRs represent a distinct class of chemokine receptors with unique regulatory functions.
- Understanding ACRs is vital for developing novel therapeutic strategies targeting chemokine-mediated diseases.
- Further research into ACR mechanisms and functions will illuminate their broader roles in physiology and pathology.

01:25Cholinergic Receptors: Muscarinic
The pharmacological actions of acetylcholine are elicited via its binding to two families of cholinergic receptors or cholinoceptors, namely, muscarinic and nicotinic receptors. Muscarinic receptors are G protein-coupled receptors and have five subtypes, M1–M5. All mAChR subtypes are activated by acetylcholine and blocked by the antagonist, atropine.
The subtypes M1, M3, and M5 couple with the Gq subunit and activate the phospholipase C (PLC) activity, mobilizing intracellular Ca2+. Activation...

01:15Receptor Downregulation in MVBs
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 activation may...

01:21Chemotaxis and Direction of Cell Migration
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...
01:15Cholinergic Receptors: Nicotinic
Nicotinic receptors are ligand-gated ion channels that are activated by acetylcholine and nicotine. Upon activation, they cause a rapid increase in the permeability of cells to K+, Na+, and Ca2+, followed by depolarization and excitation. They are in the autonomic ganglia, skeletal neuromuscular junction, CNS, and adrenal medulla.
There are two types of nicotinic receptors: neuromuscular (NM/NM/N1) and neuronal (NN/NN/N2). The two families differ based on their location and selectivity to...

01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
01:15G Protein-coupled Receptors
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
