Dimensional engineering of interlayer for efficient large-area perovskite solar cells with high stability under ISOS-L-3 aging test
The utilization of low-dimensional perovskites (LDPs) as interlayers on three-dimensional (3D) perovskites has been regarded as an efficient strategy to enhance the performance of perovskite solar cells. Yet, the formation mechanism of LDPs and their impacts on the device performance remain elusive. Herein, we use dimensional engineering to facilitate the controllable growth of 1D and 2D structures on 3D perovskites. The differences of isomeric ligands in electrostatic potential distribution and...
SMARCA4 regulates the NK-mediated killing of senescent cells
Induction of senescence by chemotherapeutic agents arrests cancer cells and activates immune surveillance responses to contribute to therapy outcomes. In this investigation, we searched for ways to enhance the NK-mediated elimination of senescent cells. We used a staggered screen approach, first identifying siRNAs potentiating the secretion of immunomodulatory cytokines to later test for their ability to enhance NK-mediated killing of senescent cells. We identified that genetic or...
A STING-CASM-GABARAP pathway activates LRRK2 at lysosomes
Mutations that increase LRRK2 kinase activity have been linked to Parkinson's disease and Crohn's disease. LRRK2 is also activated by lysosome damage. However, the endogenous cellular mechanisms that control LRRK2 kinase activity are not well understood. In this study, we identify signaling through stimulator of interferon genes (STING) as an activator of LRRK2 via the conjugation of ATG8 to single membranes (CASM) pathway. We furthermore establish that multiple chemical stimuli that perturb...
Part of ancient Britain was a woman’s world, burials reveal
2000-year-old graves suggest women wielded as much—and sometimes more—power than men in some Celtic tribes
AI could help develop cheaper, faster, and more effective snake antivenoms
“It’s really this whole change from letting the animals’ immune system do the work to now being able to do it very intentionally on the computer.”
Plasma Proteomic Signature as a Predictor of Age Advancement in People Living With HIV
Due to the increased burden of non-AIDS-related comorbidities in people living with HIV (PLHIV), identifying biomarkers and mechanisms underlying premature aging and the risk of developing age-related comorbidities is a priority. Evidence suggests that the plasma proteome is an accurate source for measuring biological age and predicting age-related clinical outcomes. To investigate whether PLHIV on antiretroviral therapy (ART) exhibit a premature aging phenotype, we profiled the plasma proteome...
