Transient Receptor Potential Vanilloid 1 (TRPV1) is a non-selective cation channel predominantly expressed in sensory neurons and plays a crucial role in the detection of noxious stimuli, particularly heat and capsaicin. Its discovery in 1997 marked a significant milestone in understanding thermosensation and pain transduction mechanisms. Subsequently, the development of stable cell lines expressing Mouse TRPV1 in Human Embryonic Kidney 293 (HEK293) cells has provided a valuable tool for investigating TRPV1 pharmacology and function. This cellular model, established through stable transfection techniques, allows for controlled and reproducible studies on TRPV1-mediated signaling pathways and drug interactions. The availability of Mouse TRPV1 Stable Cell Line - HEK293 has greatly facilitated research into pain modulation, thermoregulation, and the development of TRPV1-targeted therapeutics.
The TRPV1 ion channel plays a critical role in detecting both thermal and chemical pain sensations. Researchers demonstrate TRPV1's role in thermal and chemical pain sensation. TRPV1 activation leads to Ca2+-dependent desensitization, including acute desensitization and tachyphylaxis. They reveal that the strength of stimulation regulates whole-cell TRPV1 tachyphylaxis. Using light-sheet microscopy and pH-sensitive sensor pHluorin, they observe TRPV1 endocytosis and exocytosis trafficking, linking tachyphylaxis to TRPV1 recycling to the plasma membrane. This activity-dependent trafficking, associated with distinct Ca2+ signals, involves synaptotagmin 1 and 7-mediated recycling routes, influen cing TRPV1 surface expression and nociceptive response.
Figure 1. TRPV1's role in synaptotagmin-mediated regulation of recycling was investigated by researchers. Syt1 facilitated TRPV1 recovery during capsaicin-induced tachyphylaxis. Low capsaicin-evoked TRPV1 recycling was facilitated by Syt1, not Syt7, in HEK cells expressing TRPV1 and Syt1. (Tian Q, et al., 2019)
Using Creative Biogene's Mouse TRPV1 Stable Cell Line - HEK293 in similar experiments could offer several improvements. Firstly, employing a stable cell line ensures consistent expression levels of TRPV1 across experiments, reducing variability. This stability allows for more reliable and reproducible results compared to transient transfections. Furthermore, the use of a stable cell line saves time and resources by eliminating the need for repeated transfections and selection processes, thereby streamlining experimental workflows.
