Hevin Overexpression in Astrocytes Slows Cognitive Decline in Alzheimer's Model Mice
Publicado em 26 de fevereiro de 2025
Hevin is a circulating signal molecule that appears to be involved in the regulation of connectivity between neurons in the brain, inducing the formation of synapses. To the degree that this increases neuroplasticity, one would expect it to help resist the harmful effects of Alzheimer's disease pathology. It does this not by reducing the ongoing damage to neurons and their connections, but by allowing the brain to better adapt to or recover from that damage. This sort of approach is a [...]

Klotho Argued to Reduce Glial Cell Inflammation
Publicado em 08 fevereiro 2023Why does increased klotho expression extend life in mammals? While evidence shows klotho to improve cognitive function, it is also thought to largely function in the kidneys, and thus effects on brain aging are indirect. The research noted here challenges that, though it is conducted on cells in culture, not in living animals. The researchers suggest that klotho will reduce age-related inflammation in brain tissue by suppressing the inflammatory response [...]ver notícia -
Strength Training and Aerobic Exercise Reduce Cancer Mortality
Publicado em 17 agosto 2021Researchers here note that undertaking strength training and aerobic exercise acts to reduce mortality due to cancer, to a similar degree as these activities are known to reduce all cause mortality in later life. The mechanisms involved are likely diverse, but it is worth noting that (a) muscle tissue is metabolically active in beneficial ways, such that more muscle is better than less muscle, (b) better immune function is linked to exercise, and immune [...]ver notícia -
Functional "Mini-liver" Created by 3D Bioprinting
Publicado em 18 dezembro 2019Original story by Maria Fernanda Ziegler, Agência FAPESP Using human blood cells, Brazilian researchers have succeeded in obtaining hepatic organoids (“mini-livers”) that perform all of the liver’s typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others. The innovation permits the production of hepatic tissue in the laboratory in only 90 days and may in the future become an alternative to organ transplantation. The [...]ver notícia
