No STINGs attached: How APOE-Christchurch dampens Alzheimer's pathology

3 months ago
The "Christchurch" protective variant in the APOE gene has recently been identified, but its mechanisms of action remain unknown. In this issue of Immunity, Naguib and Lopez-Lee et al. provide evidence for the APOE-Christchurch variant suppressing microglial cGAS-STING responses and increasing clearance of pathological tau aggregates in mouse models of Alzheimer's disease.

Altered dynamic functional connectivity and reduced higher order information interaction in Parkinson's patients with hyposmia

3 months ago
Hyposmia, a common non-motor symptom in Parkinson's disease (PD) linked to reduced odor sensitivity, is associated with brain structural and functional changes, but dynamic brain activity and altered regional information exchange remain underexplored, limiting insight into underlying brain states. We selected 15 PD patients with severe hyposmia (PD-SH), 15 PD patients with normal cognition (PD-CN), and 15 healthy controls (HC). Using functional MRI, we assessed the brain's spatiotemporal...

Translational fidelity and longevity are genetically linked

3 months ago
Aging is a series of adverse changes over time that increases mortality risk. Several hypotheses have been proposed to explain aging, including Leslie Orgel's Error-Catastrophe Theory, which asserts that translation errors erode the translational machinery, become self-amplifying, and eventually lead to death. Evidence for the theory is scarce, especially regarding intra-specific fidelity-longevity correlations. Here, we demonstrate that the correlation can be hidden by the constrained evolution...

Multimodal profiling reveals tissue-directed signatures of human immune cells altered with age

3 months ago
The immune system comprises multiple cell lineages and subsets maintained in tissues throughout the lifespan, with unknown effects of tissue and age on immune cell function. Here we comprehensively profiled RNA and surface protein expression of over 1.25 million immune cells from blood and lymphoid and mucosal tissues from 24 organ donors aged 20-75 years. We annotated major lineages (T cells, B cells, innate lymphoid cells and myeloid cells) and corresponding subsets using a multimodal...

Circadian clocks and periodic anticipated fasting prevent fasting-associated hepatic steatosis in calorie restriction

3 months ago
Calorie restriction (CR) improves health and longevity. CR induces a periodic fasting cycle in mammals; our study compares CR with unanticipated fasting (F), when the food is unexpectedly withheld. F induces hepatic steatosis, whereas CR reduces it; surprisingly, the difference is not due to hepatic β-oxidation. Liver transcriptome analysis identifies fatty acid transporters (Slc27a1 and Slc27a2), triglyceride (TAG) synthesis (Gpat4), and lipid storage (Plin2 and Cidec) genes to be upregulated...
