THRB and retinal degeneration: Authors suggest that TRβ1, the predominant TRβ isoform at mature ages, may have a role in the survival of both cone photoreceptors and retinal pigment epithelium cells (Ng et al., 2023), as described in other retinal degeneration models (Ma et al., 2014; Ma et al., 2017; Ma et al., 2022), and now in the IRD patients of our cohort.
