Mitogen Activated Protein Kinase Phosphatase-1 Prevents The Development Of Tactile Sensitivity In A Rodent Model Of Neuropathic Pain, Christian Ndong, Russell P. Landry, Joyce A. Deleo, Edgar A. Romero-Sandoval

Neuropathic pain due to nerve injury is one of the most difficult types of pain to treat. Following peripheral nerve injury, neuronal and glial plastic changes contribute to central sensitization and perpetuation of mechanical hypersensitivity in rodents. The mitogen activated protein kinase (MAPK) family is pivotal in this spinal cord plasticity. MAPK phosphatases (MKPs) limit inflammatory processes by dephosphorylating MAPKs. For example, MKP-1 preferentially dephosphorylates p-p38. Since spinal p-p38 is pivotal for the development of chronic hypersensitivity in rodent models of pain, and p-p38 inhibitors have shown clinical potential in acute and chronic pain patients, we hypothesize that induction of …


Cannabinoid Receptor Type 2 Activation Induces A Microglial Anti-Inflammatory Phenotype And Reduces Migration Via Mkp Induction And Erk Dephosphorylation, Edgar A. Romero-Sandoval, Ryan Horvath, Russell P. Landry, Joyce A. Deleo May 2009

Cannabinoid receptor type 2 (CBR2) inhibits microglial reactivity through a molecular mechanism yet to be elucidated. We hypothesized that CBR2 activation induces an anti-inflammatory phenotype in microglia by inhibiting extracellular signal-regulated kinase (ERK) pathway, via mitogen-activated protein kinase-phosphatase (MKP) induction. MKPs regulate mitogen activated protein kinases, but their role in the modulation of microglial phenotype is not fully understood.
