A study in a mouse model of tau protein build-up in the brain, similar to that seen in later stage Alzheimer’s disease (AD), shows that changes to the microbiome in these animals can impact the degree and progression of neurodegeneration observed. As reported in the Jan. 12, 2023, study published in Science, the researchers found that mice that were germ free and those given antibiotics to change their gut microbiome early in life had significant reductions in brain atrophy compared with those with a standard microbiome.

Bottneuro AG closed the first tranche of a bridge round, bringing its total capital raise in 2022 to $4.3 million. This is being used to develop its noninvasive, domestic therapy for treating early moderate-stage Alzheimer’s patients.

Researchers from Yale University and affiliated organizations published data from a study that aimed to assess the mechanistic and pathophysiological importance of plaque-associated axonal spheroids (PAASs) in Alzheimer’s disease (AD).
