The SENSible Blog discusses the development of rejuvenation biotechnology around the world: progress being made in the field of longevity, the design of medical therapies to cure, reverse and prevent the diseases and disabilities of aging, and much more.

Our content is a blend of popular interest articles – labelled “Easy Reads”, and designed to require no specific background knowledge – as well as more detailed scientific commentaries, labelled as “In-Depth” and aimed towards readers with some grounding in the biological/medical sciences.

By Looped Hook and Targeting Crook: Potential Game-Changer for “Allotopic” Mitochondrial RNA

UCLA Researchers have exploited a recently-discovered mammalian system for the mitochondrial import of nuclear-encoded RNA to import, express, and demonstrate functional protein translation from engineered mRNA and tRNA constructs. They used this system, with modifications for mitochondrial targeting and orthotopic translation, to rescue respiration in human mitochondriopathy cells. While further characterization and extension is clearly needed, this approach appears offer great promise for the correction of age-related mitochondrial DNA mutations.

NFT-Specific Tau Vaccine Arrests Tangle Progress

The promising results of immunotherapy for the treatment and prevention of Alzheimer’s disease has sparked an interest in utilizing the same approach for other forms of aging damage, including the clearance of pathological tau species from within neurons. A group led by Dr. Lars Ittner of the University of Sydney has recently published promising results from studies using a vaccine targeted at the neurofibrillary tangles (NFTs) that are characteristic of established tau accumulation.

How to Disable a Cellular Bomb: Findings and Tools on the Machinery of ALT

APBs – protein complexes associated with telomeric DNA in ALT (Alternative Lengthening of Telomeres) cancer cells – are the leading candidates for the sub-cellular site at which the ALT mechanism occurs. Recent work involving the generation of artificial APBs has shed light on their composition and function, providing hints as to how ALT might be disabled.

With True Cells Come True Benefits: the Potential of Human Pluripotent Stem Cells Released in a Model of Parkinson’s Disease

Parkinson’s disease is characterised by the loss of dopaminergic neurons from the substantia nigra, and cell therapy is being actively pursued as a means to replace the losses. Most trials to date have used fetal tissue, an approach that although transiently effective is unscalable and prone to immune rejection. Human dopaminergic neurons differentiated from stem cells have historically had poor therapeutic efficiency, but a new study using an improved differentiation protocol has shown much more positive results.

Novel Abeta Vaccine Reports First Human Data

Aggregates of beta-amyloid protein (Abeta) and other malformed proteins accumulate in both “normal” brain aging and neurodegenerative disease, leading to neuronal loss. Their removal by immunotherapy is a central plank of the SENS platform, and the most clinically advanced. Gantenerumab, a new fully human anti-Abeta monoclonal antibody, has just completed a Phase I trial.
