Combined epineurial therapy with neutralizing antibodies to tumor necrosis factor-alpha and interleukin-1 receptor has an additive effect in reducing neuropathic pain in mice.
Monotherapy with antibodies to tumor necrosis factor-alpha (TNF) or interleukin-1 receptor 1 (IL-1R1) reduces hyperalgesia in an animal model of painful neuropathy. Here we investigated whether combined therapy with epineurial anti-TNF and anti-IL-1R1 antibodies produces a further advantage. ⋯ There were no detectable differences in IL-1beta and TNF endoneurial protein expression between animals with monotherapy and combined treatment. We conclude that combined anti-cytokine therapy may be a useful strategy in the treatment of neuropathic pain.

Clinical TrialHuman anterior and frontal midline theta and lower alpha reflect emotionally positive state and internalized attention: high-resolution EEG investigation of meditation.
EEG spectral power and coherence estimates in the individually defined delta, theta, alpha-1, alpha-2, and alpha-3 bands were used to identify and characterize brain regions involved in meditative states, in which focused internalized attention gives rise to emotionally positive "blissful" experience. Blissful state was accompanied by increased anterior frontal and midline theta synchronization as well as enhanced theta long-distant connectivity between prefrontal and posterior association cortex with distinct "center of gravity" in the left prefrontal region (AF3 site). Subjective scores of emotional experience significantly correlated with theta, whereas scores of internalized attention with both theta and alpha lower synchronization. Our results propose selective associations of theta and alpha oscillating networks activity with states of internalized attention and positive emotional experience.
