Involvement of enkephalins and delta-opioid receptors in the expression of levodopa-induced dyskinesia in a model of hemiparkinsonian rat
Poster Apr 02, 2008
This study was performed to test the involvement of d-opioid receptors in dyskinesia induced by L-DOPA in hemiparkinsonian rats. Our results indicate that endogenous enkephakins modulate the expression of L-DOPA-induced dyskinesia. It also appears that d-opioid receptors located on corticostriatal terminals could be involved in the development of these dyskinesia. These results confer on d-opioid antagonists interesting properties in the improvement of Parkinson’s disease therapy.
The presence of CelTOS mAb significantly inhibited oocyst development in mosquitoes in both in vivo and in vitro assays. Importantly, the experimental results with an innovative in vivo humanized mouse model confirmed that circulating anti-CelTOS antibody effectively inhibits P. falciparum ookinete development to oocyst in mosquitoes. These results support the development of CelTOS as a transmission blocking vaccine.
