A new study has found a negative association between unprocessed meat consumption and cognitive decline in carriers of the “pro-Alzheimer’s” APOE ε4 allele. This counterintuitive connection might have something to do with human evolution [1]. The meat connection The APOE gene, which produces apolipoprotein E, a protein central to lipid transport in the brain and...

Researchers publishing in Cell Reports Medicine have described the development of a lipid nanoparticle (LNP) that delivers mRNA to neurons in order to stop the formation of tau aggregates and fight Alzheimer's disease. Tau and amyloids Amyloid beta deposition between neurons and tau aggregation within neurons are both hallmarks of Alzheimer's disease, and evidence suggests...

A recent study suggests that cognitive enrichment throughout life is associated with reduced dementia risk, and it has the potential to delay the onset of dementia and mild cognitive impairment by five to seven years [1]. Cognitive stimulation Engagement in cognitively stimulating activities has been linked to lower dementia incidence, better cognitive function, and a...

Scientists have applied partial reprogramming to memory-encoding neurons (engrams) and achieved memory improvements in Alzheimer’s models and wild-type mice [1]. Rejuvenating neurons Partial cellular reprogramming, which uses certain factors to rejuvenate cells while maintaining their identity) has shown promise across various conditions and cell types, including neurons [2]. Rejuvenating these long-lived brain cells is imperative...

A team of researchers has biologically engineered T cells with currently available Alzheimer's drugs in order to directly attack the characteristic amyloid plaques of Alzheimer's disease. Building on the current paradigm Most Alzheimer's treatments used in the clinic are -mabs, monoclonal antibodies that are designed to attack the amyloid beta plaques that accumulate in the...

Using an ingenious CRISPR-based screening technique, scientists have found a protein that tags tau for degradation and is more strongly expressed in tau-resilient neurons [1]. Some neurons are more equal than others The accumulation of tau protein fibrils in neurons is a hallmark of Alzheimer’s and several other diseases [2]. Scientists have long noticed that...
