Whats the context?
A couple of TRP (Transient receptor potential) channels are well known for the mediation of chemesthetic sensations, yet, their functions in non-sensory systems are less well understood.
What challenge is tackled?
Thus, clarifying the non-sensory function of these channels as well as identifying their endogenous ligands is of great scientific interest.
What is done?
Focusing on primary human immune cells the RNA-expression of TRP-channels as well as the cellular responses to known TRP-channel ligands are studied.
What has come out of your work?
These analyses showed that for example TRPV1 ligands from ginger modulate the human cellular immune response, indicating a natural role of this channel in the human immune system.
Whats the value?
Our work can provide a better general understanding regarding the function of chemosensory ion-channels in non-sensory systems.
