The reduction in dementia risk caused by the shingles vaccine has us wondering how!?!? The mystery continues: Data from 3884 participants in the Health and Retirement Study suggest metrics of biological aging, including inflammation, are also improved by the vaccine. tinyurl.com/tuprm4nb

Association between shingles vaccination and slower biological aging: Evidence from a U.S. population-based cohort study

Abstract. There is growing interest in whether adult vaccines such as shingles vaccine may slow biological aging beyond preventing acute infections. Using

Disappointingly, the latozinemab trial for FTD-GRN failed to meet clinical endpoints (tinyurl.com/5f33sd88). However, the biomarker endpoint of elevated plasma PGRN was achieved. Perhaps PGRN localization to the lysosome, not extracellular fluids, is more critical for FTD-GRN (see PMID: 39565694).

A patient was diagnosed with corticobasal syndrome. BUT, neuropath exam showed frontotemporal atrophy with a-synuclein glial cytoplasmic inclusions and neuronal cytoplasmic inclusions. By cryoEM, the a-syn fibers look just like MSA fibers. Authors conclude "FTLD-synuclein" is a rare MSA subtype

A patient with a PSEN2 mutation should have had early dementia onset but didn't! Despite a high amyloid plaque burden there was limited tau pathology. Authors suggest tau pathology is the driver of dementia onset. Putative protective gene variants: FAM1515B, CEP290, GPCPD1, PRICKLE3, ANKRD36C.
