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...

According to a new study, as many as 90% of Alzheimer’s cases can be attributed to “suboptimal” variants of the APOE gene. These results highlight the gene’s importance for Alzheimer’s prevention [1]. Three alleles of APOE A growing amount of research links Alzheimer’s disease to the gene APOE, which codes for apolipoprotein E [2]. This...

A recent study investigated biomarkers that can help monitor trajectories of Alzheimer’s disease-related molecular processes, such as neuronal cell death, and how patients respond to treatments. The authors reported that using biomarkers enabled them to gain insights into the molecular processes that contribute to improved cognition following human recombinant granulocyte macrophage colony-stimulating factor (GM-CSF, sargramostim)...

In a new study, the amino acid arginine shows promise in animal models of amyloid aggregation due to its ability to promote protein folding. The researchers suggest that it could be useful for early prevention and treatment of Alzheimer's [1]. Hold it and fold it Amino acids, the building blocks of proteins, can be potent...
