Aging Compromises Terminal Differentiation Program of Cytotoxic Effector Lineage and Promotes Exhaustion in CD8+ T Cells Responding to Coronavirus Infection

open access: yesAging Cell, EarlyView.
In a MHV infection model with age‐associated increased mortality, we demonstrate that aging impairs, instead of promoting, the terminal differentiation program of virus‐specific CD8+ T cells through downregulating key transcriptional regulators of terminal differentiation.

Organ Specificity and Commonality of Epigenetic Aging in Low‐ and High‐Running Capacity Rats

open access: yesAging Cell, EarlyView.
Cardiorespiratory fitness (CRF) is not associated with epigenetic clocks, including newly developed ones. On the other hand, CRF is associated with global methylation profiles and promoter methylation in organ‐specific and organ‐common manner. ABSTRACT Epigenetic drift, which is gradual age‐related changes in DNA methylation patterns, plays a ...

Targeting CA2 Perineuronal Nets Restores Recognition Memory and Theta Oscillations in Aged Mice

open access: yesAging Cell, EarlyView.
Targeting CA2 perineuronal nets restores social/non‐social recognition memory and theta oscillations in aged mice: Aged mice displayed deficits in both social and object recognition memory, which were accompanied by enhanced perineuronal nets (PNNs) density and reduced theta power in the dCA2 region.

Gastrointestinal Barrier Disruption in Post‐COVID Syndrome Fatigue Patients

open access: yesAllergy, EarlyView.
Gastrointestinal (GI) barrier disruption in the context of SARS‐CoV‐2 infection is associated with the development of Post‐COVID Syndrome (PCS) Fatigue. Pre‐existing GI complaints may predispose to fatigue development. Monitoring GI symptoms and markers before, during, and after SARS‐CoV‐2 infection is crucial for identifying predictive clinical ...

Role for Complement C5 in Eosinophilic Inflammation of Severe Asthma

open access: yesAllergy, EarlyView.
Complement activation module, particularly C5, is positively associated with eosinophilic inflammation in severe asthma cohorts. Elevated C5 expression correlates with poor lung function improvement and persistent eosinophilic inflammation. Mouse model studies confirm that C5 exacerbates eosinophilic inflammation, highlighting its potential as a ...

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Efficacy and safety of HRS‐5965 monotherapy in complement inhibitor–naïve patients with paroxysmal nocturnal haemoglobinuria

open access: yesBritish Journal of Haematology, EarlyView.
Summary Paroxysmal nocturnal haemoglobinuria (PNH) is a rare, life‐threatening disorder characterized by complement‐mediated haemolysis, leading to anaemia and thrombosis. HRS‐5965 is a novel, oral, selective complement factor B inhibitor targeting the alternative pathway, potentially reducing both intra‐ and extravascular haemolysis.

The physiological and pathological effects of sphingolipid metabolism and signaling in the central nervous system

open access: yesBrain Pathology, EarlyView.
Sphingolipids are vital components of cell membranes. Metabolic disruptions of sphingolipids, including ceramide and sphingosine‐1‐phosphate, are linked to neurological disorders. This article summarizes the classification, structure, and metabolic processes of sphingolipids, and the physiological and pathological effects of sphingolipid metabolism and
