Ávalos Y, et al. Cell Death Dis. 2022 Jul 28;13(7):659. doi: 10.1038/s41419-022-05109-9. Cell Death Dis. 2022. PMID: 35902579 Free PMC article.
Palmitic acid (PA) is significantly increased in the hypothalamus of mice, when fed chronically with a high-fat diet (HFD). PA impairs insulin signaling in hypothalamic neurons, by a mechanism dependent on autophagy, a process of lysosomal-me …

Benoit SC, Kemp CJ, Elias CF, Abplanalp W, Herman JP, Migrenne S, Lefevre AL, Cruciani-Guglielmacci C, Magnan C, Yu F, Niswender K, Irani BG, Holland WL, Clegg DJ. Benoit SC, et al. J Clin Invest. 2009 Sep;119(9):2577-89. doi: 10.1172/JCI36714. Epub 2009 Aug 10. J Clin Invest. 2009. PMID: 19726875 Free PMC article.
Here, we assessed whether one specific isoform, PKC-theta, was expressed in critical CNS regions that regulate energy balance and whether it mediated the deleterious effects of diets high in fat, specifically palmitic acid, on hypothalamic insulin …

Palmitic acid triggers inflammatory responses in N42 cultured hypothalamic cells partially via ceramide synthesis but not via TLR4.
Sergi D, Morris AC, Kahn DE, McLean FH, Hay EA, Kubitz P, MacKenzie A, Martinoli MG, Drew JE, Williams LM. Sergi D, et al. Nutr Neurosci. 2020 Apr;23(4):321-334. doi: 10.1080/1028415X.2018.1501533. Epub 2018 Jul 21. Nutr Neurosci. 2020. PMID: 30032721
A high-fat diet induces hypothalamic inflammation in rodents which, in turn, contributes to the development of obesity by eliciting both insulin and leptin resistance. ...To elucidate this mechanism, the effect of fatty acids on the expression of the pro-infl …

Palmitate attenuates insulin signaling and induces endoplasmic reticulum stress and apoptosis in hypothalamic neurons: rescue of resistance and apoptosis through adenosine 5' monophosphate-activated protein kinase activation.
Mayer CM, Belsham DD. Mayer CM, et al. Endocrinology. 2010 Feb;151(2):576-85. doi: 10.1210/en.2009-1122. Epub 2009 Dec 1. Endocrinology. 2010. PMID: 19952270
Hypothalamic insulin signaling is essential to the maintenance of glucose and energy homeostasis. During pathological states, such as obesity and type 2 diabetes mellitus, insulin signaling is impaired. One key mechanism involved in the development of insu …
