Hematopoietic stem and progenitor cells as a reservoir for trained immunity

1 month 2 weeks ago
Human and murine studies reveal that innate immune cells are able to mount enhanced responses to pathogens after primary inflammatory exposure. Innate immune memory has been shown to last for months to years, longer than the lifespan of most innate immune cells. Indeed, long-lived hematopoietic stem and progenitor cells (HSPCs) serve as a cellular reservoir for innate immune memory. In this review, we summarize the evidence that innate immune memory is epigenetically encoded in HSPCs, and we...

Neurocognitive and emotional benefits of choir singing and their mediating factors across adulthood

1 month 2 weeks ago
BACKGROUND: Our understanding on how cognitive and socioemotional well-being factors interact throughout adulthood has increased remarkably over the past decades, encouraging the use of cognitively engaging leisure activities, such as music, to promote healthy ageing. Choir singing has attracted particular interest in this regard with its established benefits on socioemotional well-being. Outside the clinical context, however, the cognitive and well-being effects induced by musical activities...

The association between playing Ma-jong, chess, and card games and cognitive function improvement in middle-aged and elderly Chinese: cross-sectional evidence from CHARLS

1 month 2 weeks ago
CONCLUSIONS: PMCC activities are associated with cognitive function improvement in middle-aged and elderly adults in China. These findings suggest that engaging in PMCC activities could serve as a potential protective factor for enhancing cognitive health in this population, providing a basis for incorporating PMCC into strategies aimed at promoting cognitive well-being and healthy aging.

Modulation of fenestrated vasculature in the median eminence and area postrema in response to neurotoxin exposure and its impairment in aging

1 month 2 weeks ago
Effective communication between the brain and peripheral tissues is crucial for homeostasis and health, and its impairment is a defining feature of aging. Circumventricular organs, characterized by the presence of fenestrated capillaries and absence of a blood-brain barrier (BBB), play a crucial role in controlling substance exchange between the brain and the blood. To date, adaptive changes in fenestrated vasculature in response to environmental insults remain poorly understood. In this study,...
