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.

Active Aß Immunization Reverses (Some) Neuritic Pathology

Neurites – projections from a neuron’s cell body – become structurally abnormal in proximity to the extracellular aggregates that occur in both neurodegenerative disease and “normal” cognitive aging. These structural abnormalities have been suggested to play a role in cognitive pathology, by disrupting normal synaptic integration. Active immunotherapy against beta-amyloid (using the AN1792 antibody) has now been shown to reverse much of this structural deformity, even in cases where plaque clearance is incomplete.

An AID to Faster, More Efficient iPS Derivation?

New insights into the role of AID, a DNA demethylase, in the reprogramming process that produces induced pluripotent stem (iPS) cells are expected to allow greater efficiencies and permit the elimination of clinically problematic viral vectors and proto-oncogenes.

Progress and New Cautions in an “Universal Amyloid Strategy”

Serum amyloid P component (SAP) is a universal constituent of amyloid deposits, apparently regardless of the disease in question (and thus the other proteins present). Although methods have been developed to eliminate SAP from the body, this approach could have potentially serious side-effects. We announce a new SENS Research Foundation-funded project to tackle amyloid accumulation via the alternative, more direct approach of catalysing degradation of the pathogenic protein components.

Aß “Affibodies:” A Novel Route to Comprehensive Clearance?

Affibodies are artificial, antibody-like proteins generated through protein engineering techniques. ZAβ3, an affibody that targets amyloid-beta (Abeta), has been shown to prevent plaque formation and neurotoxicity in animal models of Alzheimer’s disease. Affibodies like ZAβ3 might have important practical advantages over antibody-based Abeta-clearing agents, making this a promising new approach.

CR Mimetics and the Definition of Insanity

Widespread optimism about the life-extension potential of calorie restriction (CR) is tempered by doubt that any significant number of people will ever adopt it as a lifestyle. However, thus far the search for “CR mimetics” – drugs that convey the same benefits on a normal calorie intake – has been fruitless. Here we review some of the prominent examples.
