Title

Young versus aged microbiota transplants to germ-free mice: increased short-chain fatty acids and improved cognitive performance

Overall design

The aim of this study was to test whether the aged gut microbiome alone is sufficient to decrease short-chain fatty acids in the host and produces cognitive decline. C57BL/6 mice were divided into the following 2 groups (n = 11 per group): (1) young microbiota transplant group, and (2) aged microbiota transplant group. Fecal transplant gavages from aged (18-20 months) or young (2-3 months) mice into germ-free mice were initiated at ~3 months of age. Mice with an aged microbiome demonstrated depressive-like behavior over the 3 months following the initial microbiota transplant. Fecal short-chain fatty acids were measured by LC-MS.
