abstract = {Increased catabolism has recently been recognized as a
clinical manifestation of amyotrophic lateral sclerosis
(ALS). The hypothalamic systems have been shown to be
involved in the metabolic dysfunction in ALS, but the exact
extent of hypothalamic circuit alterations in ALS is yet to
be determined. Here we explored the integrity of large-scale
cortico-hypothalamic circuits involved in energy homeostasis
in murine models and in ALS patients.The rAAV2-based
large-scale projection mapping and image analysis pipeline
based on Wholebrain and Ilastik software suites were used to
identify and quantify projections from the forebrain to the
lateral hypothalamus in the SOD1(G93A) ALS mouse model
(hypermetabolic) and the FusΔNLS ALS mouse model
(normo-metabolic). 3 T diffusion tensor imaging
(DTI)-magnetic resonance imaging (MRI) was performed on 83
ALS and 65 control cases to investigate cortical projections
to the lateral hypothalamus (LHA) in ALS.Symptomatic
SOD1(G93A) mice displayed an expansion of projections from
agranular insula, ventrolateral orbitofrontal and secondary
motor cortex to the LHA. These findings were reproduced in
an independent cohort by using a different analytic
approach. In contrast, in the FusΔNLS ALS mouse model
hypothalamic inputs from insula and orbitofrontal cortex
were maintained while the projections from motor cortex were
lost. The DTI-MRI data confirmed the disruption of the
orbitofrontal-hypothalamic tract in ALS patients.This study
provides converging murine and human data demonstrating the
selective structural disruption of hypothalamic inputs in
ALS as a promising factor contributing to the origin of the
hypermetabolic phenotype.},
