In Ngsk prion protein (PrP)-deficient mice (NP(0/0)), ectopic expression of PrP-like protein Doppel (Dpl) in central neurons induces significant Purkinje cell (PC) death resulting in late-onset ataxia. NP(0/0) PC death is partly prevented by either knocking-out the apoptotic factor BAX or overexpressing the anti-apoptotic factor BCL-2 suggesting that(More)
Ruta chalepensis L. is used in the traditional herbal treatment of various diseases. The aim of this work is to investigate the effect of different extracts of R. chalepensis L. on inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) gene expressions and their antioxidant capacity on murine RAW 264.7 macrophage challenged with(More)
Ciguatoxins are the major toxins responsible for ciguatera fish poisoning, a disease dominated by muco-cutaneous sensory disorders including paresthesiae, cold dysesthesia and pruritus. While the ciguatoxins are well known to target voltage-gated sodium channels (VGSCs), the ensuing molecular mechanisms underlying these sensory disorders remain poorly(More)
Recent studies have demonstrated that keratinocytes closely participate in sensory transduction, and therefore, intra-epidermal free nerve endings are not exclusive transducers of pain. This discovery implies the existence of close afferent communication from keratinocytes to sensory neurons. Although reciprocal interactions between keratinocytes and(More)
