Decoding Merkel Cell-Neuron "Divorce" in Tactile Neuropathy

Maksimovic et al. (2014) showed Merkel cells actively tune touch receptors via a division of labor (static vs. dynamic stimuli). Yet, we don’t know if disrupted Merkel-neuron communication underlies neuropathy. This idea would induce diabetic neuropathy in mice expressing optogenetic actuators in Merkel cells. We’d assess whether light-driven Merkel cell activation rescues tactile deficits in SAI afferents. Unlike studies focusing on neuronal damage alone (Source 3), this targets non-neuronal contributors. Impact: Could redefine neuropathy treatment by restoring "epidermal intelligence" to touch pathways.
