Toward precision interventions and metrics of inflammaging

3 months 2 weeks ago
Inflammaging describes a chronic, systemic, low-grade inflammatory state that is recognized as a major risk factor for age-related diseases (ARDs) and a pivotal convergence point of multiple biological mechanisms involved in aging. Here, we discuss the heterogeneity of inflammaging, proposing that it emerges as a consequence of each individual's lifelong exposures to inflammatory stimuli, shaped by a unique combination of genetics, lifestyle, socioeconomic conditions and environmental factors...

Interplay between depressive symptoms and Alzheimer's disease dementia: unraveling the potential roles of ADAM10 and Negr1

3 months 2 weeks ago
Late-onset depression (LOD) is closely linked to Alzheimer's disease (AD), marked by shared biological pathways and common risk factors. The neurobiological alterations associated with depression, particularly the dysregulation of amyloid-β (Aβ), play a critical role in the acceleration of disease progression. In individuals suffering from LOD, Aβ peptides - specifically Aβ40 and Aβ42 - exhibit distinct profiles in plasma, cerebrospinal fluid (CSF), and brain tissue, highlighting the substantial...

Mitochondrial bioenergetics in resilience of older adults with gynecologic cancer: design and rationale of a pilot study

3 months 2 weeks ago
Resilience-the ability to recover and maintain function following stresses-is a critical factor influencing treatment tolerance and recovery in older adults with cancer. Despite the high incidence of gynecologic cancers in postmenopausal individuals, resilience in this population remains underexplored, even though patients commonly face compounded stress from both chemotherapy and surgery. The goal of our research is (1) to test the feasibility of cognitive and physical function assessments in...

Stress granule-mediated ZBP1 activation drives necroptotic cell death in non-obstructive azoospermia and testicular aging

3 months 2 weeks ago
Male infertility remains a major unmet medical challenge, with poorly defined molecular mechanisms and no effective therapies. Here, we identify a stress granule-mediated necroptotic pathway as a key driver of non-obstructive azoospermia, a severe form of male infertility marked by the loss of spermatogenesis. Environmental or physiological stress activates eIF2α kinases, inducing stress granule formation and the recruitment of ZBP1 and RIPK3 into a cytoplasmic complex. This assembly triggers...

HAPLN2 forms aggregates and promotes microglial inflammation during brain aging in mice

3 months 2 weeks ago
Protein aggregation is a hallmark of neurodegenerative diseases and is also observed in the brains of elderly individuals without such conditions, suggesting that aging drives the accumulation of protein aggregates. However, the comprehensive understanding of age-dependent protein aggregates involved in brain aging remains unclear. Here, we investigated proteins that become sarkosyl-insoluble with age and identified hyaluronan and proteoglycan link protein 2 (HAPLN2), a hyaluronic acid-binding...

From clock to clock: Therapeutic target discovery for aging and age-related diseases

3 months 2 weeks ago
The aging population worldwide necessitates the development of novel therapeutics that enhance the quality of life by preventing and treating age-related diseases. In this review, we first discuss the advantages of a dual-purpose target identification strategy for aging and age-related diseases, with assessment of the hallmarks of aging as an approach to identify such dual-purpose targets. Resulting from a convergence of aging research with machine learning (ML) and other artificial intelligence...
