NaV1.8 is a voltage gated sodium channel mainly expressed on the membrane of thin diameter c-fibre neurons involved in the transmission of pain signals. In these neurons NaV1.8 is essential for the propagation of action potentials. NaV1.8 is located in lipid rafts along the axons of sensory neurons and disruption of these lipid rafts leads to NaV1.8 dependant conduction failure. Using computational modelling, I show that the clustering of NaV1.8 channels in lipid rafts along the axon of thin diameter neurons is energetically advantageous and requires fewer channels to conduct action potentials. During an action potential NaV1.8 currents across the membrane in these thin axons are large enough to dramatically change the sodium ion concentration gradient and thereby void the assumptions upon which the cable equation is based. Using scanning electron microscopy NaV1.8 is seen to be clustered, as are lipid raft marker proteins, on neurites at scales below 200nm. FRET signals show that the lipid raft marker protein Flotillin is densely packed on the membrane however disruption of rafts does not reduce the FRET signal from dense protein packing. Using mass spectrometry I investigated the population of proteins found in the lipid rafts of sensory neurons. I found that the membrane pump NaK-ATPase, which restores the ion concentrations across the membrane, is also contained in lipid rafts. NaK-ATPase may help to offset concentration changes due to NaV1.8 currents enabling the repeated firing of c-fibres, which is associated with spontaneous pain in chronic pain disorders.
