In conclusion, mitophagy pathways play an important role in maintaining physiological homeostasis, are involved in the mechanisms of aging and neurodegenerative disorders, and represent promising targets for the development of potential therapeutic agents aimed at regulating mitochondria quality control in neurons and glial cells. A significant number of molecules that induce or inhibit mitophagy are currently under consideration, which may be useful for testing hypotheses or developing drugs for the treatment of neurodegenerative diseases. The validation of promising drugs in animal and cell models, including neurons and ...

B2M as a Surface Marker of Cellular Senescence
Before the advent of the first senolytic drugs capable of selectively destroying senescent cells, it was thought by many that progress towards producing rejuvenation in the old via the safe elimination of senescent cells from the body would require the identification of surface markers that are distinctive to the state of senescence. Given a surface marker that clearly and distinctively identifies a cell population, a broad range of strategies become available for the development of targeted therapies. As it turned out,, however, the first senolytics took advantage of the peculiarities of the internal state of senescent ce...

In this study, we therefore analysed the influence of lithium treatment on lifespan and parameters of health during ageing in mice. To determine the concentration of lithium suitable to be administered in a longitudinal ageing study, we first tested the effects of lithium chloride (LiCl) in doses from 0.01 to 2.79 g LiCl per kg chow. C57Bl/6J mice fed with 1.05-2.79 g/kg LiCL in the diet showed lithium plasma levels between 0.4 and 0.8 mM/l. While plasma levels to 0.4 and 0.8 mM/l are well tolerated by human patients, at doses above 1.44 g LiCl/kg, we observed an obvious dose-dependent polydipsia combined with a dis...

Exploring Mechanisms by Which Exercise Slows Cancer Progression
Cancer patients who exercise tend to do better than those who do not. While one cannot escape an established cancer via physical activity, one can modestly slow it down, it appears. Researchers here explore some of the mechanisms by which exercise can achieve this goal, focusing on muscle tissue signaling that both slows cancer cell growth and provokes greater immune system activity. The usual path forward for this sort of research, given a large enough effect size to be interesting, is to try to find a way to deliver additional signal proteins as a form of treatment. This might be achieved directly using recombinant prote...

In conclusion, premature thymic involution and chronic inflammation greatly contribute to increased morbidity and mortality in CKD patients. Mechanisms are likely to be multiple and interlinked. Even when the quest to fountain of youth is a pipe dream, there are many scientific opportunities to prevent or to, at least in part, reverse CKD-related immune senescence. Further studies should precisely define most important pathways driving premature immune ageing in CKD patients and best therapeutic options to control them.

Genetic Variants Associated with Visceral Fat Accumulation Correlate with Longevity
It is well established that excess visceral fat is harmful. This tissue is metabolically active, and generates increased chronic inflammation through numerous mechanisms: a greater number of senescent cells; signaling by fat cells that appears similar to that produced by infected cells; increased debris from dead and dying fat cells that provokes the immune system. Overweight and obese people have a shorter life expectancy, greater incidence of age-related disease, and higher lifetime medical costs, with these disadvantages increasing with a larger burden of visceral fat tissue. It is not surprising, therefore, to find tha...

A woman in her 60s with palpitations, chest discomfort, and multiple misdiagnoses by both EM and Cardiology!!
 Written by Pendell MeyersA woman in her 60s was shopping when she suddenly experienced palpitations and chest " discomfort. " She denied outright chest pain or dyspnea. She walked across to the street to my Emergency Department. She had no known prior history of dysrhythmias or heart disease, but had known hypertension, breast cancer, diabetes, and obesity. She has had episodes of palpitations in the past, followed by holter monitor workups which did not reveal any cause of palpitations. However, her symptoms today feel worse than prior episodes, and she has never felt the " chest discomfort " with prior palpitations...

In this study, mature DCs (mDCs), generated from the GM-CSF and IL-4 induced bone marrow cells, were intravenously injected into wild-type mice. Three days later, assays showed that the mDCs were indeed able to return to the thymus. Homing DCs have been mainly reported to deplete thymocytes and induce tolerance. However, medullary TECs (mTECs) play a crucial role in inducing immune tolerance. Thus, we evaluated whether the mDCs homing into the thymus led to TECs depletion. We cocultured mDCs with mTEC1 cells and found that the mDCs induced the apoptosis and inhibited the proliferation of mTEC1 cells. These effects were onl...

In conclusion, patients over 90 years of age had an overall low prevalence of fractures and relative preservation of bone health, suggesting a preserved bone molecular profile in these individuals. Epigenetic factors and activity levels might also have favorably affected bone health. The low percentage of osteoporosis and fractures likely reduced the morbidity and mortality in this population, potentially contributing to their overall longevity.

Fecal Microbiota Transplant as a Treatment for Neurodegenerative Conditions
It is thought that an appreciable fraction of the chronic inflammation of aging is caused by changes in the gut microbiome. There is a bidirectional interaction between the immune system and the microbial populations of the intestinal tract. The immune system gardens these populations, destroying problematic microbes. Microbes secrete metabolites and other molecules that can either benefit or harm the function of the immune system, the harms caused particularly by those microbes capable of provoking a sustained inflammatory response. The immune system declines with age for a range of reasons, and reduced efficacy in immune...

CaMKII Oxidation in Heart Function as an Example of Antagonistic Pleiotropy
CaMKII can be oxidized readily in mammals, but not in flies. This is a small change in DNA sequence, but it produces a greater physical capacity in youth, coupled to a greater vulnerability and loss of tissue function in the environment of chronic oxidative stress characteristic of old age. This is a good example of antagonistic pleiotropy, a concept at the center of the consensus on how evolution reliably leads to the production of species that undergo aging. Individuals that reproduce successfully early in life are favored, and thus mutations - such as CaMKII vulnerability to oxidation - that provide an advantage in yout...

Is this blog political?
Of course. Read the paragraph at the top. Public health is fundamentally political -- well, I ' m not sure that ' s exactly the right word, but it ' s very much about public policy, which is a primary determinant of public health. Much of what public health researchers do is to assess the impact of policies on health. Furthermore, all categories of public policy affect public health, not just health care policy or environmental regulations. Transportation, land use management, taxation, education, law enforcement -- you name it. We say " health in all policies, " and it is our job, as scientists, to elucidate those relatio...
