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...

In Aging Cell, researchers have explained how the sirtuin SIRT6 protects against proteostasis-related brain disorders by maintaining the function of nucleoli and limiting protein production. The nucleus and nucleoli Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is one of...

Scientists have found that a gene on the X chromosome, which escapes silencing, promotes inflammation and neurodegeneration in a mouse model of multiple sclerosis, but the effects can be reversed with metformin. Human RNA sequencing data supports these findings [1]. Why are women more vulnerable? Multiple sclerosis (MS) is an autoimmune and neurodegenerative disease that...

Scientists have found a pathway that regulates protein aggregation, a cause of several age-related neurodegenerative diseases. United by abnormal protein aggregation Most neurodegenerative diseases are age-related, and many of them are similar in other ways. For instance, amyotrophic lateral sclerosis (ALS), Huntington’s disease, and Alzheimer’s disease have all been linked to abnormal protein aggregation [1],...

In a recent study, researchers identified the critical role that lithium plays in brain health and the development of mild cognitive impairment and Alzheimer’s disease. Supplementing with a lithium salt called lithium orotate can reverse many of its cognitive decline-related changes on the molecular and cellular levels [1]. The road less traveled Understanding the underlying...

Researchers have recently published a review on how cannabis use among older adults impacts age-related conditions and longevity [1]. Cannabinoids and longevity In recent years, researchers have observed an increase in cannabis use among older adults, mostly for chronic conditions, such as arthritis, pain, sleep improvement, anxiety, and depressive symptoms. However, there is also a...
