Genetic manipulation of tumor necrosis factor levels in eyes of Mertknmf12 mutants. Fundus photographs of P45 Mertknmf12/Mertknmf12; Tnfabc+/+ (A) and Mertknmf12/Mertknmf12; Tnfabc−/− (B) mice are presented. Note the pan-retinal patches in the latter. Histologic sections are of central (C) and peripheral (D) retinas of a 1-month-old Mertknmf12/Mertknmf12; Tnfabc+/+ retina and central (E) and peripheral (F) retinas of an age-matched Mertknmf12/Mertknmf12; Tnfabc−/− mouse. The thickness of the ONL is similar between Mertknmf12/Mertknmf12; Tnfabc+/+ and Mertknmf12/Mertknmf12; Tnfabc−/− mice (arrows). Central (G) and peripheral (H) retinas of a 3-month-old Mertknmf12/Mertknmf12; Tnfabc+/+ retina and central (I) and peripheral (J) retinas of an age-matched Mertknmf12/Mertknmf12; Tnfabc−/− retina are presented. Although the ONL of Mertknmf12/Mertknmf12; Tnfabc+/+ retinas remains relatively intact (G, H, arrows), extensive thinning of the ONL is evident in the central and peripheral retina (I, J, arrows, respectively) of the Mertknmf12/Mertknmf12; Tnfabc−/− mice. Scale bar, 50 μm (CJ).
