A newly published personal tribute in Brain Medicine offers a rare window into the remarkable life and influence of Dr. Seymour "Si" Reichlin, who turned 100 in June 2024. Written by former endocrine fellow Dr. Leonard Kapcala, the article chronicles their 48-year relationship and illuminates how Reichlin's brilliance, mentorship, and humanity shaped generations of neuroendocrinology researchers.

Prions transmit their abnormally folded shape onto other proteins. Researchers designed a synthetic fragment of the tau protein that exhibits prion-like behavior. Misfolded tau proteins are the hallmark of many neurodegenerative diseases, including Alzheimer’s disease and frontotemporal dementia. Study revealed crucial role of water organization in the tau misfolding process.

This study investigates the potential of methyl eugenol (ME), a compound found in the essential oils of various plants, to inhibit oxidative stress and its impact on diseases associated with this process. ME has been shown to possess antioxidant properties and antiproliferative activity in several cancers. It also demonstrates neuroprotective potential in conditions such as Alzheimer’s disease and ischemic brain injury. The mechanism of action involves the activation of the nuclear factor erythroid 2-related factor 2, which facilitates the transcription of antioxidant genes and modulation of pathways such as AMP-activated protein kinase/glycogen synthase kinase 3 beta, thereby reducing the production of reactive oxygen species and pro-inflammatory cytokines. However, research has identified potential toxicological risks associated with ME, including hepatotoxicity and changes in the gut microbiota. These findings highlight the need for caution when considering prolonged exposure to this compound.

Patients with spastic paraplegia type 15 develop movement disorders during adolescence that may ultimately require the use of a wheelchair. In the early stages of this rare hereditary disease the brain appears to play a major role by over-activating the immune system, as shown by a recent study published in the Journal of Experimental Medicine. The study was led by researchers at the University of Bonn and the German Center for Neurodegenerative Diseases (DZNE). These findings could also be relevant for Alzheimer's disease and other neurodegenerative conditions.
