Morphine 6-14 interleukin 1 beta Mus musculus 64-72 22439811-4 2012 We examined acute morphine-induced activation of satellite glial cells (SGCs) and up-regulation of IL-1beta in dorsal root ganglia (DRGs), and further investigated the involvement of MMP-9 in these opioid-induced peripheral changes. Morphine 18-26 interleukin 1 beta Mus musculus 99-107 22439811-6 2012 The acute morphine-induced GFAP expression is transient, peaking at 2 h and declining after 3 h. Acute morphine treatment also increased IL-1beta immunoreactivity in SGCs and IL-1beta activation in DRGs. Morphine 10-18 interleukin 1 beta Mus musculus 137-145 22439811-6 2012 The acute morphine-induced GFAP expression is transient, peaking at 2 h and declining after 3 h. Acute morphine treatment also increased IL-1beta immunoreactivity in SGCs and IL-1beta activation in DRGs. Morphine 10-18 interleukin 1 beta Mus musculus 175-183 22439811-6 2012 The acute morphine-induced GFAP expression is transient, peaking at 2 h and declining after 3 h. Acute morphine treatment also increased IL-1beta immunoreactivity in SGCs and IL-1beta activation in DRGs. Morphine 103-111 interleukin 1 beta Mus musculus 137-145 22439811-6 2012 The acute morphine-induced GFAP expression is transient, peaking at 2 h and declining after 3 h. Acute morphine treatment also increased IL-1beta immunoreactivity in SGCs and IL-1beta activation in DRGs. Morphine 103-111 interleukin 1 beta Mus musculus 175-183 22439811-9 2012 Importantly, morphine-induced DRG up-regulation of GFAP expression and IL-1beta activation was abolished after Mmp9 deletion or naloxone pre-treatment. Morphine 13-21 interleukin 1 beta Mus musculus 71-79 22439811-10 2012 Finally, intrathecal injections of IL-1beta-selective siRNA not only reduced DRG IL-1beta expression but also prolonged acute morphine-induced analgesia. Morphine 126-134 interleukin 1 beta Mus musculus 35-43 22439811-11 2012 CONCLUSIONS: Acute morphine induces opioid receptors- and MMP-9-dependent up-regulation of GFAP expression and IL-1beta activation in SGCs of DRGs.
