A range of gene therapies are presently available in the medical tourism community of clinics outside the US and Europe, largely originating with a small number of companies such as BioViva Sciences and Triple Helix Science. These gene therapies tend to involve intramuscular (targeting muscle) or intranasal (targeting
PD-L1 found on the surface of cells is a well known immune checkpoint protein. When it binds to the receptor PD-1 found on the surface of T cells and B cells, it acts to suppress immune activity. This is a necessary brake to avoid runaway immune reactions, but because it is also abused by cancer cells to shield them fr
Fight Aging! publishes news and commentary relevant to the goal of ending all age-related disease, to be achieved by bringing the mechanisms of aging under the control of modern medicine. This weekly newsletter is sent to thousands of interested subscribers. To subscribe to the newsletter, please visit: https://www.fig
Type 1 conventional dendritic cells are a subclass of dendritic cell known to be an important component of the immune response to pathogens and cancerous cells, particularly focused on stimulating the activity of cytotoxic T cells. The cancer research community, as is often the case when it comes to specific components
It is well understood in the aging research community that the lack of a useful, consensus measure of biological age or pace of biological aging is a considerable hindrance to progress. If researchers could quickly measure the pace of aging or the state of aging in a robust way, then discovery and optimization of inter
The cGAS protein is a sensor for mislocalized DNA in the cell cytoplasm, and responds by triggering STING, a regulator of the inflammatory response to damage and dysfunction. The cGAS-STING interaction produces some fraction of the maladaptive chronic inflammation characteristic of aging, as, among other reasons, mitoc
Rationing of sugar in the United Kingdom in the years immediately following the Second World War forms a natural experiment in the long term effects of changes in human nutrition that can be explored in great detail given the establishment of the UK Biobank. Researchers here show that lower sugar intake in early life c
Later stages of Alzheimer's disease and other tauopathies are characterized by the aggregation of altered tau protein, and a toxic surrounding biochemistry that provokes inflammation and destroys neurons. So far little headway has been made towards therapies that can halt tau pathology, by clearing harmful tau or preve
Researchers here provide an initial proof of concept demonstration of a novel foundation for replacing lost visual capacity in cases of retinal degeneration, without addressing the underlying pathology that causes loss of function in photoreceptor cells. Recall that direct stimulation of retinal cells by grid electrode
Researchers here provide a proof of concept for the use of Raman spectroscopy to non-invasively measure the burden of senescent cells in an imaged tissue. This works because Raman imaging can provide distinct signatures of different molecules via scattering of photons. Provided the field of imaging is sufficiently cons
One of the more interesting new concepts in aging research is that repeated activation of the DNA damage response may cause epigenetic changes in the management of nuclear DNA structure that are characteristic of aging. It neatly explains how stochastic DNA damage to unused DNA sequences can possible contribute to agin
Suppression of cancer is a necessary component of species longevity, and finding out how exactly cancer incidence is in some cases dramatically reduced is one of the primary goals for the field of comparative biology. Here, researchers survey known cancer-associated sequences across the genomes of long-lived and short-
