HRN_VP4 [FBbt_00047225]

Adult hygrosensory neuron that expresses the humidity-sensing Ionotropic receptor (Ir) 40a, and the co-receptors Ir93a and Ir25a and innervates the antennal lobe glomerulus VP4 bilaterally (Enjin et al, 2016; Knecht et al., 2016; Marin et al., 2020. There are two subtypes that transduce signals from the basiconic sensilla of chamber I or the blunt-tipped sensilla of chamber II (pore-less sensilla) of the sacculus (Enjin et al., 2016; Marin et al., 2020. Its activity is increased by dry air and decreased by humid air (Knecht et al., 2016; Enjin et al., 2016. It develops from an Nba precursor (Benton et al., 2025. There are around 15 of these cells on each side (Benton et al., 2025. (Knecht et al., 2016, Benton et al., 2025, Benton et al., 2009, Silbering et al., 2011, Marin et al., 2020, Enjin et al., 2016)
