Caption Increased total and phosphorylated TDP-43 in the cytoplasm of thalamic neurons in 12-month-old homozygous Grntm2.1Far/Grntm2.1Far (GrnR493X/R493X) and Grntm1.1Far/Grntm1.1Far (Grn-/-) mice. (A-C) Confocal microscopic images of thalamic neurons showed that TDP-43, detected by an N terminus antibody, was nearly exclusively in the nucleus of TuJ1+ neurons in wild-type (WT, Grn+/+) mice (A). (B) Compared with WT mice, thalamic neurons in age-matched Grntm2.1Far/Grntm2.1Far mice showed a significant increase of TDP-43 in the cytoplasm (indicated by the arrowheads). (C) A similar increase in cytoplasmic TDP-43 was detected in age-matched Grntm1.1Far/Grntm1.1Far thalamic neurons. (D-F) Confocal microscopic images of thalamic neurons showed no detectable p-TDP-43 in the nucleus or cytoplasm of neurons in WT mice (D). (E) Compared with WT mice, thalamic neurons in age-matched Grntm2.1Far/Grntm2.1Far mice showed a significant increase of p-TDP-43 in the cytoplasm (indicated by the arrowheads), but no detectable p-TDP43 in the nuclei. (F) A similar increase in cytoplasmic p-TDP-43 was detected in age-matched Grntm1.1Far/Grntm1.1Far thalamic neurons. (Scale bars, 20 um.)
