Mouse TRPV1 Stable Cell Line - HEK293

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.
