Webb1 okt. 2024 · However, biophysical mechanisms for sperm transport are much less studied and understood. Thermotaxis, for example, is a powerful, physical signaling system that is known to direct sperm inside the female genital tract, although the intimate mechanisms by which this effect is launched are yet to be elucidated.

Taken together, the above results suggest that in thermotaxis, as in chemotaxis (Armon and Eisenbach, 2011), a negative stimulus (i.e. a decreasing ... Webb4 mars 2005 · Some of the thermoTRPs (TRPV1, TRPM8, and TRPA1) are receptors of sensory compounds that feel hot, cold, or burning (capsaicin, menthol, mustard oil, and cinnamaldehyde), consistent with a physiological role of these ion channels in thermosensation and pain ( 2, 15, 16 ). No sensory compound is known to activate TRPV3. splat space
