TRN_VP2
ID: FBbt_00007575
Adult unilateral thermosensory neuron of the aristal sensillum with an axon that innervates antennal lobe glomerulus VP2 (Stocker et al., 1990; Benton et al., 2025). It has small, finger-like sensory endings (Budelli et al., 2019) and expresses the warmth-sensor Gr28b.d (Ni et al., 2013). It is transiently activated by temperature increases and transiently inhibited by temperature decreases (Budelli et al., 2019). In addition, it has increased steady state spiking at higher temperatures (Budelli et al., 2019). There are around 3-4 of these cells per hemisphere (Marin et al., 2020). (Stocker et al., 1990, Gallio et al., 2011, Benton et al., 2025, Marin et al., 2020, Budelli et al., 2019, Ni et al., 2013)
