Extracellular matrix (ECM) molecules are highly variable in their composition and receptor recognition. Their ubiquitous expression profile has been linked to roles in cell growth, differentiation, and survival. Recent work has identified certain ECM molecules that serve as dynamic signal modulators, versus the more-recognized role of chronic modulation of signal transduction. In this study, we investigated the role that fibronectin plays in the dynamic modulation of TRPV1 translocation to the plasma membrane in trigeminal ganglia (TG) sensory neurons. Confocal immunofluorescence analyses identify co-expression of the TRPV1 receptor with integrin subunits that bind fibronectin. TG neurons cultured upon or treated with fibronectin experienced a leftward shift in the EC50 of capsaicin-stimulated neuropeptide release. This fibronectin-induced increase in TRPV1 sensitivity to activation is coupled by an increase in plasma membrane expression of TRPV1, as well as an increase in tyrosine phosphorylation of TRPV1 in TG neurons. Furthermore, TG neurons cultured on fibronectin demonstrated an increase in capsaicin-mediated Ca+2 accumulation relative to neurons cultured on poly-D-lysine. Data presented from these studies indicate that fibronectin stimulates tyrosine-phosphorylation-dependent translocation of the TRPV1 receptor to the plasma membrane, identifying fibronectin as a critical component of the ECM capable of sensory neuron sensitization.
