Identification of cholinergic cells with chemosensory traits in the porcine uterus.

ABSTRACT: Chemosensory cells are specialized epithelial cells that act as sentinels near body entry sites. The majority of these cells express a cholinergic phenotype and utilize the taste signaling system to monitor the mucosal environment for potentially harmful substances, triggering protective reflexes. We report the identification of cells with a putative chemosensory role in the uterus. Presumptive chemosensory cells were immunoreactive to key components of the taste transduction, including the transient receptor potential channel M5 (TRPM5) and the phospholipase Cβ2 (PLCB2). These cells localized to endometrial glandular and luminal epithelia, while absent from myometrium and perimetrium. Double immunofluorescence revealed co-expression of chemosensory cell markers with the acetylcholine (ACh
