NGF Up-regulates TRPA1: Implications for Orofacial Pain

A. Diogenes, A.N. Akopian, and K.M. Hargreaves
The authors demonstrate, for the first time, that nerve growth factor evokes the functional up-regulation of the transient receptor potential ankyrin repeat 1 in trigeminal ganglia neurons, and these enhanced activities could play an important role in the development of hyperalgesia following nerve injury and inflammation in the orofacial region.

Effect of Facial Sensory Re-training on Sensory Thresholds

G.K. Essick, C. Phillips, and J. Zuniga
Neurosensory testing data were analyzed from the first multi-center clinical trial that assessed the benefit of facial sensory re-training on the sensory recovery of patients after orthognathic surgery, and the re-trained persons exhibited less impairment than non-retrained persons in two-point perception, suggesting that they experienced or interpreted tactile stimuli differently.
