There are Many Possible Paths to Immunotherapy for Senescent Cell Destruction
Rising numbers of senescent cells are one of the root causes of aging, a process that arises from the normal operation of youthful metabolism, yet results in accumulated damage and failure over time. Senescent cells generate signaling that degrades tissue function, breaks down and remodels tissue structure, spurs chronic inflammation, and alters the behavior of surrounding cells for the worse. Evidence shows their presence to be a contributing cause of a range of common fatal age-related conditions. In a youthful body, near all cells that become senescent and fail to self-destruct as a result are promptly eliminated by the...

Fight Aging! Newsletter, February 12th 2018
In conclusion, most experimental data on immune changes with aging show a decline in many immune parameters when compared to young healthy subjects. The bulk of these changes is termed immunosenescence. Immunosenescence has been considered for some time as detrimental because it often leads to subclinical accumulation of pro-inflammatory factors and inflammaging. Together, immunosenescence and inflammaging are suggested to stand at the origin of most of the diseases of the elderly, such as infections, cancer, autoimmune disorders, and chronic inflammatory diseases. However, an increasing number of gerontologists have chall...

Models Suggest that Declining T Cell Production is the Primary Reason for Age-Related Increases in Cancer Risk
In the open access paper noted here, researchers use modeling to suggest that age-related decline of the thymus, and thus of the immune system, is more important than mutation as a determinant of cancer risk. Cancer is at root caused by mutational damage to DNA. While DNA repair and replication mechanisms are highly efficient, mutations nonetheless occur - and must occur at some rate in order for evolution to take place. It is a numbers game, in that the more time, the more cells, and the more cell activity, the greater the odds that a cancerous mutation will occur. Mutation rates are also affected by external factors such...

In this study, we tested the hypothesis that Gbp1 plays a role in regulating immunometabolism and senescence of macrophages. We found that Gbp1 was mainly expressed in macrophages, but not adipocytes in response to IFNγ/LPS stimulation; Gbp1 expression was significantly decreased in inguinal white adipose tissue (iWAT) of high-fat diet (HFD)-fed and aged mice. We also observed that downregulation of Gbp1 in macrophages resulted in M1 polarization and impairment of mitochondrial respiratory function possibly via disrupting mitophagy activity. Moreover, macrophages with downregulated Gbp1 displayed dampened glycolysis and e...

An Impressive Performance in Clearing Cancer from Mice via Immunotherapy
Immunotherapy is a cut above chemotherapy and radiotherapy: at its best, it is significantly more effective and significantly less harmful to the patient. It has still required years, a great deal of funding, and many failures for those best approaches to arise. Nonetheless, the report here is a cheering example for the sizable fraction of us expected to suffer cancer at some point in the years ahead if the condition is not soon brought under medical control. This immunotherapy appears highly effective, and just importantly, adaptable to many types of cancer. This potential for broad application is the most important aspec...

This study is the longest, prospective randomized controlled trial that has documented the physiological effects of supervised, structured exercise training in a group of sedentary but healthy middle-aged adults. The key finding is that 2 years of exercise training performed for at least 30 minutes, 4 to 5 days per week, and including at least 1 high-intensity interval session per week results in a significant reduction in LV chamber and myocardial stiffness. The use of high-resolution, invasively measured LV pressure-volume curves and comparison with an attention control group enhances the confidence in this conclusion. T...

Viruses and Checkpoint Inhibitors Combine to Form an Effective Cancer Treatment
Researchers here demonstrate a combination therapy that is far more effective in destroying a target cancer than either of its components alone. Effective synergies between therapies are discovered at a fairly low rate by the scientific community, which is in part a reflection of their rarity, but also a reflection of the fact that the regulatory system is not set up to encourage the commercial development of combination therapies. The number of trials for such efforts is small in comparison to single therapy tests. There isn't a good response to this observation beyond the usual calls for more freedom and more funding.

Discussion of advocacy for the cause is a usual feature of our community, as we try things and attempt to make progress in persuading the world that rejuvenation research is plausible, practical, and necessary. There are more people engaged in advocacy now than at any time in the past decade, and so discussions of strategy come up often. New ventures kicked off in 2017 include the Geroscience online magazine, and among the existing ventures the LEAF / Lifespan.io volunteers seem to be hitting their stride. The mainstream media continues to be as much a hindrance as a help, and where it is a help you will usually find Aubre...

Request for Startups in the Rejuvenation Biotechnology Space, 2018 Edition
A shift in the character of rejuvenation research has taken place over the past couple of years. Greater attention is being given to this work, and the most advanced lines have made - or will soon make - the leap from non-profit laboratory and philanthropic funding to for-profit startup company and venture funding. A growing community of angel investors and a fair few venture funds are now interested in supporting startup companies whose founders implement approaches to rejuvenation that follow the SENS model of repairing fundamental damage. A brief selection includes Kizoo Technology Ventures, Methuselah Fund, the Longevi...

Fight Aging! Newsletter, December 18th 2017
In this study, we asked people in an open-ended way about their desire for longer life: Would you like to have more time? What age would you like to become? This was something more specific than asking about a preference for survival without reference to any length of time; about one's plans for the future; or whether people see the future as open or limited, as in studies of future time perspective. Our attempt was to discover whether there were preferred temporal spans with which older adults framed their futures and plans.
The two-question series about extra years and desired age ("How old would you like to becom...

The Boys From Silicon Valley
By MARGALIT GUR-ARIE
A few weeks ago one man, named @jack, decided that millions of people will be allowed to use up to 280 characters when expressing themselves on Jack’s public square platform. One man decides how many letters each and every one of us, including the “leader of the free world”, can use when we talk to each other. Just like that. Nobody seemed the least bit perturbed by this notion. Another dude, named Mark, decided to ask people for nude pictures of themselves, so he can better protect them from the bad guys. We shrugged that off too. Then, in a most embarrassing exercise in public humiliation, our ...

In this study, we integrated atomic force microscopy (AFM) and molecular approaches to determine whether increased stiffness of aortic VSMCs in hypertensive rats is ROCK-dependent, and whether the anti-hypertensive effect of ROCK inhibitors contributes to the reduction of aortic stiffness via changing VSMC mechanical properties.
Despite a widely held belief that aortic stiffening is associated with changes in extracellular matrix proteins and endothelial dysfunction, our recent studies demonstrated that intrinsic stiffening of aortic VSMCs, independent of VSMC proliferation and migration, is an important contributo...
