Abstract

Acetylcholine (ACh) is the main neurotransmitter in cholinergic neuroendocrine system and plays indispensable role in modulating diverse immune response. As an important transporter in choline uptake, choline transporter-like proteins (CTLs) can control ACh synthesis and release indirectly in multiple organisms. In the present study, cgi-miR-2d, an invertebrate-specific miRNA in oyster Crassostrea gigas, is proved to repress the synthesis/release of ACh by targeting CgCTL1 and choline uptake in haemocytes during the early-stage of pathogen infection. In short, an opposite expression pattern between CgCTL1 and cgi-miR-2d is observed during Vibrio splendidus infection, accompanied with changes in haemolymph ACh. Besides, expression level of CgCTL1 is found significantly repressed after cgi-miR-2d overexpression in vivo while both haemocyte choline and haemolymph ACh also decreased simultaneously, which is similar with that in CgCTL1 knock-down assay. As a result, the expression of two tumor necrosis factor like proteins and the bacteriostatic activity of oyster haemocytes, are found altered significantly by either gain-of-function cgi-miR-2d or knock-down of CgCTL1. To our knowledge, this is the first miRNA identified in invertebrates that can target ancient cholinergic system and augment immune response during infection.
