Transient Receptor Potential channels are exquisite molecular transducers of multiple physical and chemical stimuli, hence the raising interest to study their relevance to Sensory Biology. Here we discuss a number of aspects of the biophysical and pharmacological properties of TRP channels, which we consider essential for a clear understanding of their sensory function in vivo. By examining concrete examples extracted from recent literature we illustrate that TRP channel research is a field in motion, and that many established dogmas on biophysical properties, drug specificity and physiological role are continuously reshaped, and sometimes even dismantled.
