研究概览

Taken together, our study investigated the role of NR2A/B in central nociceptive sensitization and suggested that RVG-EXOs-mediated delivery of siRNAs targeting NR2A and NR2B was effective for orofacial NP treatment. Engineered exosomes have great potential as drug delivery systems for treating diseases.

核心发现

Orofacial neuropathic pain (NP) is a common complication in oral clinical practice that severely affects quality of life.

However, NP does not currently receive effective medications.

Engineered exosomes have great potential as drug delivery systems for treating diseases.

Here, patch clamp techniques showed that the deficiency of N-methyl-D-aspartic acid receptor (NMDAR) subunits 2A and 2B reversed the spontaneous excitatory postsynaptic current (sEPSC) frequency and neuronal excitability in the spinal trigeminal nucleus caudalis (SpVc) after injury, which is an effective therapeutic target for NP.
