| Outline of Final Research Achievements |
We investigated GABA system with the trigeminal ganglion with the possibility to contribute to trigeminal neuralgia.We found heterogeneous expressions of GABABR1 and GABABR2 subunits and auxiliary subunits KCTD12 and KCTD16 in the rat trigeminal ganglion (TG).
The spinal trigeminal nucleus caudalis (Sp5C) is a critical relay site for processing nociceptive afferent input from the orofacial area and for its modulation by neuroplastic changes.Axons originating from TG carry information from facial and cranial nociception into brainstem.After entering brainstem, forming the spinal trigeminal tract and terminate in Sp5C.In this study, interactions of GABABR1, GABABR2, KCTD12 and KCTD16 in TG and brainstem including Sp5C using co-immunoprecipitation assay and immnohistohemistry.
