In conclusion, this is the first report to show that pyroptotic cell death occurs in the aging brain and that the inflammasome can be a viable target to decrease the oxidative stress that occurs as a result of aging. Reducing Levels of Protein Manufacture Slows Measures of Aging in Nematodes Researchers here demonstrate that an antibiotic slows aging in nematode worms, providing evidence for it to work through a reduction in protein synthesis. Beyond a slowing of aging, one of the con...

AbstractRegenerative medicine as a background of stem cell research and therapy has a long history. A wide variety of diseases including Parkinson ’s disease, heart diseases, multiple sclerosis, spinal cord injury, diabetes mellitus and etc. are candidate to be treated using different types of stem cells. There are several sources of stem cells such as bone marrow, umbilical cord, peripheral blood, germ cells and the embryo/fetus tissues. Fe tal stem cells (FSCs) and embryonic stem cells (ESCs) have been described as the most potent stem cell source. Although their pluri- or multipotent properties leads to promising ...

A little more than a decade has passed since the development of a simple cell reprogramming approach that reliably created pluripotent stem cells from ordinary somatic cells, known as induced pluripotent stem cells. These stem cells are very similar, near identical in fact, to the embryonic stem cells that were previously the only reliable source of cells capable of forming any cell type in the body. Arguably the most important aspect of induced pluripotency is not the promise of the ability to generate patient-matched cells for regenerative therapies and tissue engineering of replacement organs, but rather that it is a lo...

This article, however, is more of a commentary on high level strategy and the effects of regulation, coupled with a desire to forge ahead rather than hold back in the matter of treating aging, thus I concur with much more of what is said than is usually the case. For decades, one of the most debated questions in gerontology was whether aging is a disease or the norm. At present, excellent reasoning suggests aging should be defined as a disease - indeed, aging has been referred to as "normal disease." Aging is the sum of all age-related diseases and this sum is the best biomarker of aging. Aging and its d...

Authors: Guan YQ, Zhao CS, Zou HQ, Yan XM, Luo LL, Wu JL, Li X, Zhang YA Abstract Whether aging or Parkinson's disease (PD) affects the responses of peripheral blood mononuclear cells (PBMCs) to immunosuppression by bone marrow‑derived mesenchymal stem cell (BM‑MSCs) and which cytokines are more effective in inducing BM‑MSCs to be immunosuppressive remains to be elucidated. PBMCs were isolated from healthy young (age 26‑35), healthy middle‑aged (age 56‑60) and middle‑aged PD‑affected individuals. All the recruits were male. The mitogen‑stimulated PBMCs and proinflammatory cytokine‑pret...

In this study, we tested whether pharmacological agonism and antagonism of dopamine D1 and D2 receptor regulate nonmotor symptoms, neural stem cell (NSC) proliferation and fate specification and explored the cellular mechanism(s) underlying dopamine receptor (D1 and D2)- mediated adult hippocampal neurogenesis in rat model of PD-like phenotypes. We found that single unilateral intra-medial forebrain bundle administration of 6-hydroxydopamine (6-OHDA) reduced D1 receptor level in the hippocampus. Pharmacological agonism of D1 receptor exerts anxiolytic and antidepressant-like effects as well as enhanced NSC proliferation, l...

Abstract In humans, oxidative stress is thought to be involved in the development of Parkinson' s disease, Alzheimer's disease, atherosclerosis, heart failure, myocardial infarction, depression. Myricitrin, a botanical flavone, is abundantly distributed in the root bark of Myrica cerifera, Myrica esculenta, Ampelopsis grossedentata, Nymphaea lotus, Chrysobalanus icaco, and other plants. Considering the abundance of its natural sources, myricitrin is relatively easy to extract and purify. Myricitrin reportedly possesses effective anti-oxidative, anti-inflammatory, and anti-nociceptive activities, and can protect a ...
