TRPV channels share general mechanisms of activation while exhibiting subtype-specific features along the activation pathway that can determine their apparent sensitivity to stimuli.
Vanilloid sensitivity has been introduced into the TRPV2 channel, revealing that the gating and permeation properties of this enigmatic TRP channel are remarkably similar to the capsaicin receptor.

The cooling agent pocket in TRPM8 is conserved in a subset of other TRPM channels and the cooling agent icilin can regulate opening of TRPM4 channels in response to calcium and voltage.

Networked cardiac control, revealed through analysis of extended baseline-state multi-channel recordings, differentiates heart failure and normal regimes highlighting the promise of peripheral neurally based clinical interventions.
Novel capsaicin analogs with conserved chemistry but varying sizes were used as molecular rulers to investigate energetics of conformational changes in the ligand-binding pocket and mechanisms of TRPV1 ligand-gating.
Highly temperature-sensitive behavior of voltage-gated potassium channels provides a mechanistic model for how heat-activated TRP channels serve as temperature and pain sensors.

The TRPV1, TRPV2 and TRPV3 channels are gated on the cytosolic side of the pore, whereas structural changes in the ion selectivity filter associated with activation don't control cation access.
