Article Title: Sorting Nexin 11 Regulates Lysosomal Degradation of Plasma Membrane TRPV3.
Article Snippet: For verification of anti-extracellular TRPV3 antibody, an antigenic peptide (Alomone), REEEAIPHPLALTHK, which corresponds to amino acid residues 464–478 of the human TRPV3 first extracellular loop, was used as a standard quality control. .. Anti-extracellular TRPV3 primary antibody (ACC-033, Alomone) was preincubated with antigenic peptide (1 μg peptide/1 μg antibody) (Alomone) and then used to detect TRPV3 protein using western blotting or immunocytochemistry. .. HEK293T cells were transfected with plasmids for 48 h. The cells were washed twice with cold PBS (pH 7.4) and lysed with IP lysis buffer [0.025 M Tris, 0.15 M NaCl, 0.001 M EDTA, 1% NP-40, and 5% glycerol (pH 7.4) plus protease inhibitors (Life Technologies)] for 30 min.

Techniques: Knock-Out, Control

( A ) In cortical L2/3 pyramidal neurons (PNs) with synaptically evoked spiking, gradual increases in brain slice temperature from 30 °C to 36°C to 39°C result in four possible outcomes: neurons remain inactive, continue spiking (STAY), stop spiking, or initiate spiking. To spike, PNs must reach the spike threshold (ST), defined as the minimal V m that elicits an action potential, which requires sufficient depolarization via the post-synaptic potential (PSP). STAY neurons consistently reach ST and continue spiking. Neurons that stop spiking fall below the level of depolarization required to reach ST, while neurons that initiate spiking achieve sufficient depolarization to newly reach ST. ( B ) STAY neurons may contain unique ion channels, such as TRPV3. TRPV3 channels are highly permeable to Ca² + ions, and Ca² + influx contributes to PN depolarization. The presence of TRPV3 facilitates greater ion entry, enabling depolarization sufficient to reach ST and sustain spiking, whereas its absence reduces depolarization to levels insufficient for spiking.
