Immunohistochemical localization of acid-sensing ion channel 2 (ASIC2) in cutaneous Meissner and Pacinian corpuscles of Macaca fascicularis

► Acid-sensing ion channel 2 (ASIC2) has been postulated as a putative mechanoprotein. ► ASIC2 expression was examined in cutaneous Meissner and Pacinian corpuscles of Macaca fascicularis. ► ASIC2 was detected in the axons of both kinds of cutaneos mechanoreceptors. ► ASIC2 may be involved in touch sense.
