Capsaicin has been used:
??to study its effects on chromatin remodeling and gene expression related to synaptic plasticity
??to study TRPV1 channel signaling in H2C1 cells (which are human embryonic kidney 293 cells expressing TRPV1 channels)

Biochem/physiol Actions

Prototype vanilloid receptor agonist. Neurotoxin; activates sensory neurons that give rise to unmyelinated C-fibers, many of which contain substance P. Topical application desensitizes the sensory nerve endings giving a paradoxical antinociceptive effect; systemic administration can be neurotoxic to capsaicin-sensitive cells, especially in newborn animals. Active component of chili peppers.
