“…Bowman's glands, for example, secrete mucus, which is essential to normal odor detection (Dear et al, 1991;Kern, 2000;Solbu and Holen, 2012). Sustentacular and microvillar cells remain somewhat mysterious, but seem to structurally support sensory neurons, phagocytose and/or detoxify potentially damaging agents, generate inflammatory cytokines, manage energetics through delivery of glucose to OSNs, and maintain local salt and water balance (Baxter et al, 2020;Lemons et al, 2017;O'Leary et al, 2019;Suzuki et al, 1996;Ualiyeva et al, 2020;Vogalis et al, 2005). Damage to support cells thus has the potential to change ion gradients and fuel availability, which in turn could acutely influence OSN firing rates.…”
