Overview

The goal of the Rohacs laboratory is to understand the mechanism of the regulation of
somatosensory ion channels
activated by thermal and mechanical stimuli. We study them at the molecular, cellular and organism
level. Our goal is to
further the understanding of the fascinating biology of somatosensation, which we believe will
ultimately lead to the
development of better pain medications with fewer, and less severe side effects.

Somatosensory touch is the least understood of the five senses at the molecular level. Due to the large receptor surface
i.e. skin, mucous membranes, bone, etc, direct study of the molecular sensors initiating the detection of mechanical or
thermal stimuli has been difficult. Most of our knowledge originates from studying the cell bodies of the primary sensory
Dorsal Root Ganglion (DRG) and Trigeminal (TG) neurons. Many of the primary sensors identified by today belong to the
Transient Receptor Potential (TRP) family of ion channels; their roles are best established in thermosensation. Piezo
channels are the best characterized mammalian mechansensitive ion channels. There are likely to be other, not yet
identified primary sensory ion channels. We study both TRP and Piezo channels using electrophysiology, fluorescence
imaging, animal behavior, molecular biology and computational modeling.
