Characterization of Bovine Adrenal Medulla as a Model of Non-histaminergic Itch

Characterization of Bovine Adrenal Medulla (BAM8-22) as a New Surrogate Model of Non-histaminergic Itch

With this experiment, the experimenter wish evaluate the role of TRPA1 on non-histaminergic itch induced by BAM8-22

With this experiment, the experimenter wish evaluate the role of TRPA1 on non-histaminergic itch induced by BAM8-22 2 (Bovine Adrenal Medulla), which is found naturally in the human body and which has proved to evoke itch. To evaluate the role of TRPA1 it will be used a TRPA1 agonist
