About 50% of these neurons die in <jats:italic>Bdnf<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice and <jats:italic>Ntf4\/5<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice. <jats:italic>Bdnf<jats:sup>\u2212\/\u2212<\/jats:sup>\/Ntf4\/5<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> double mutants lose 90\u201395% of geniculate ganglion neurons. To determine whether different subpopulations are differentially influenced by neurotrophins, we quantified neurons from two ganglion subpopulations separately and remaining taste buds at birth within each target field in wild\u2010type, <jats:italic>Bdnf<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup>, <jats:italic>Ntf4\/5<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup>, and <jats:italic>Bdnf<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup>\/<jats:italic>Ntf4\/5<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice. In wild\u2010type mice the same number of neurons innervated the anterior tongue and soft palate and each target contained the same number of taste buds. Compared to wild\u2010type mice, <jats:italic>Bdnf<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice showed a 50% reduction in geniculate neurons innervating the tongue and a 28% loss in neurons innervating the soft palate. <jats:italic>Ntf4\/5<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice lost 58% of the neurons innervating the tongue and 41% of the neurons innervating the soft palate. Taste bud loss was not as profound in the NT\u20104 null mice compared to BDNF\u2010null mice. Tongues of <jats:italic>Bdnf<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup>\/<jats:italic>Ntf4\/5<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice were innervated by 0 to 4 gustatory neurons and contained 3 to 16 taste buds at birth, indicating that some taste buds remain even when all innervation is lost. Thus, gustatory neurons are equally dependent on BDNF and NT\u20104 expression for survival, regardless of what peripheral target they innervate. However, taste buds are more sensitive to BDNF than NT\u20104 removal. J. Comp.
