    For most of us it ends here, in a fleeting moment of bliss. But then there are those tortured few for whom scratching provides little relief.

    EDITORIAL REVIEW New therapies for controlling atopic itch Masutaka FURUE,1 Takafumi KADONO2 1Department of Dermatology, Kyushu University, Fukuoka, 2Department of Dermatology, St Marianna University School of Medicine, Kawasaki, Japan ABSTRACT Chronic itch in atopic dermatitis markedly diminishes the quality of life of affected individuals. TRPA1 has emerged as a major target for histamine-independent itch. Chloroquine, an “itchy” antimalarial drug, was shown to activate both rodent mouse and rat MrgprA3 and human MrgprX1, members of the Mrgpr family that are exclusively expressed in peripheral sensory neurons Dong et al. 2001. In mice, chloroquine-responsive, MrgprA3. Responds to the itch-inducing endogenous signal histamine, and TRPA1 responds to the itch-inducing chemical chloroquine. We showed that, in sensory neurons, TRPV4 is important for both chloroquine-and histamine-induced itch and that TRPV1 has a role i n chloroquine-induced itch. Chloroquine-induced

    As far as we know, every animal with a backbone has a scratching reflex. In 1660, the German physician Samuel Hafenreffer defined an itch as "an unpleasant sensation associated with the desire to scratch." As an operational definition, it does the job.

  6. Thesensationsofpain,itch,andcoldofteninteractwitheach other. Pain inhibits itch, whereas cold inhibits both pain and itch. TRPV1 and TRPA1 channels transduce pain and itch, whereas TRPM8 transduces cold. The pruritogen chloroquine CQ was reported to excite TRPA1, leading to the sensation of itch. It is unclear how CQ excites and modulates TRPA1,

    • ExcitationandModulationofTRPA1,TRPV1,andTRPM8 Channel..
    • Facilitation of TRPV4 by TRPV1 is required for itch..
    • S1PR3 Mediates Itch and Pain via Distinct TRP Channel..

    Future studies will be required to test the roles of such candidates in chronic itch models. The ion channel TRPA1 was previously shown to mediate acute histamine-independent itch TRPA1 is required for sensory neuron activation and itch behavior downstream of two histamine-independent pruritogens, chloroquine and BAM8-22, which activate. Wiping was never observed following injection of chloroquine or BAM. Thus, we used this model to better examine the in vivo role of TRPA1 in chloroquine- and BAM-evoked itch. In the cheek assay. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.

    Minocycline and Plaquenil - Scleroderma - Inspire I take both minocycline and plaquenil. I tried weening myself off the plaquenil, but, couldn't take the pain. I've only been on the mino since February. But, so far I've had more good days than bad. And, that's a great thing. This time last year I believed my active days were over. I wasn't able to get out of bed for more than an hour at a time.
