Human CNR1 Virus-Like Particles

Cannabinoid receptor 1 (CNR1), also known as CB1, is a G protein-coupled receptor found primarily in the central nervous system (CNS) and peripheral tissues. It plays a key role in the endocannabinoid system (ECS), which regulates various physiological processes, including neurotransmission, pain perception, appetite, and immune responses. CNR1 can be activated by endogenous ligands such as anandamide and 2-arachidonoylglycerol (2-AG), as well as phytocannabinoids such as Δ9-tetrahydrocannabinol (THC). Dysregulation of CNR1 has been linked to a variety of diseases, including obesity, neurodegenerative disorders, and addiction. Due to its therapeutic potential, CNR1 has become a focus of drug development and biomedical research.

Human CNR1 virus-like particles (VLPs) are non-infectious, self-assembling nanostructures that resemble viruses but lack viral genetic material. These VLPs are specifically designed to display CNR1 on their surfaces, providing a powerful platform for studying receptor-ligand interactions, antibody development, and vaccine design. Unlike traditional cell systems, CNR1 VLPs provide a native membrane environment that preserves the conformational integrity and functionality of the receptor. This makes them ideal for high-throughput screening of CNR1-targeted drugs and for generating CNR1 antibodies for diagnostic or therapeutic purposes. Furthermore, CNR1 VLPs can be used for immunogenicity studies because they can effectively present the receptor to the immune system without the risks posed by live virus.
