5 h), chronic inflammatory (CFA 20 h and 4 days), neuropathic (spared nerve injury (SNI) 2 weeks), or control pain stimuli (saline 20 h and

4 days; sham-SNI 2 weeks). We found that after capsaicin injection in rats preconditioned with CFA inflammation (4 days), sham-SNI or with SNI neuropathic pain, the numbers (27 +/- 3, 21 +/- 2, and 21 +/- 2, respectively) and percentages (55%+/- 4, 43%+/- 2, and 42%+/- 2, respectively) of C-fos activated neurons that were Gly/GABA increased significantly as compared with control (10 +/- 1 and 25%+/- 2). The increase in the total number of C-fos activated Gly/GABA neurons was present primarily in the superficial dorsal horn (laminae I and II; control: 9%; CFA 4 days: 56%; SNI 2 weeks: 42%). This increase in C-fos activation of Gly/GABA

neurons occurred without significant changes in the total number of C-fos activated RAD001 neurons, and without any significant changes in the mechanical thresholds in the hind paws after capsaicin injection. The results showed that one-sided chronic pain, especially inflammation, significantly increases the C-fos activation pattern of spinal Gly/GABA neurons on the other side of the spinal cord. This further underlines the existence of a dynamic interaction between ipsi- and contralateral spinal neurons in the processing of nociceptive information. (C) 2011 IBRO. Published by Elsevier Ltd.

“We previously identified human scavenger receptor PF299804 cost class B, member 2 (SCARB2),

as a cellular receptor for enterovirus 71 (EV71). Emricasan concentration Expression of human SCARB2 (hSCARB2) permitted mouse L929 cells to efficiently bind to virions and to produce both viral proteins and progeny viruses upon EV71 infection. Mouse Scarb2 (mScarb2) exhibited 85.8% amino acid identity and 99.9% similarity to hSCARB2. The expression of mScarb2 in L929 cells conferred partial susceptibility. Very few virions bound to mScarb2-expressing cells. The viral titer in L929 cells expressing mScarb2 was approximately 40- to 100-fold lower than that in L929 cells expressing hSCARB2. Using hSCARB2-mScarb2 chimeric mutants, we attempted to map the region that was important for efficient EV71 infection. L929 cells expressing chimeras that carried amino acids 142 to 204 from the human sequence were susceptible to EV71, while chimeras that carried the mouse sequence in this region were not. Moreover, this region was also critical for binding to virions. The determination of this region in hSCARB2 that is important for EV71 binding and infection greatly contributes to the understanding of virus-receptor interactions. Further studies will clarify the early steps of EV71 infection.”
