Fig. 1From: IL-1β induces rod degeneration through the disruption of retinal glutamate homeostasisIL-1β induces rod photoreceptor degeneration indirectly. a Orthogonal projection of confocal Z stack images of the outer nuclear layer of TUNEL (red)- and Hoechst nuclear dye (blue)-stained mouse retinal explants after 18 h of culture with or without IL-1β (50 ng/ml). b Quantification of TUNEL+ nuclei in control and IL-1β (50 ng/ml) exposed mouse retinal explants (n = 10/group, Mann–Whitney test, *p < 0.0001). c RT-qPCR of Il1r1 mRNA normalized with the mean of 3 HKG mRNAs in retinal cell fractions (MCs: CD11b+ cells; Müller cells: CD11b−CD31−CD29+ cells; neurons: CD11b−CD31−CD29− and PR) isolated from total retina (n = 3/group, Kruskal–Wallis, Dunn’s post-test *p = 0.0023 versus MCs; n = 3/group. d Quantification of the number of DAPI+ isolated rod PRs cultured for 18 h with or without IL-1β (50 ng/ml) (n = 4/group)Back to article page
