The number of regulators of neurodegeneration that were identified in each study is shown along with the number of these genes with orthologues in C elegans. The disease models include organisms expressing forms of β-amyloid (AB), polyQ expansions (P), wild type or mutant α-synuclein (S), mutant superoxide dismutase (SOD), or mutant tau (T).
