HLA export by melanoma cells decoys cytotoxic T cells to promote immune evasion [0.03%]
黑色素瘤细胞通过输出人类白细胞抗原来诱骗细胞毒性T细胞以促进免疫逃逸

Yoav Chemla et al.
While melanoma cells often express a high burden of mutated proteins, the infiltration of reactive T cells rarely results in tumor-eradicating immunity. We discovered that large extracellular vesicles, known as melanosomes, secreted by mela...

More than a century after their discovery, neutrophils continue to puzzle immunologists. Their remarkable migratory, cytotoxic, phagocytic, and degranulating capacities gave rise to the traditional perception that they are dedicated microbe...
Are ultrasensitive ctDNA assays ready for clinical use in early-stage NSCLC? [0.03%]
超灵敏ctDNA检测在早期NSCLC中临床应用的准备就绪了吗？

Disease recurrence in early-stage non-small cell lung cancer (NSCLC) remains a persistent clinical challenge, underscoring the need for better prognostic biomarkers. In this preview, we highlight the clinical implications of ultrasensitive ...
Sensitized mast cells for targeted drug delivery and augmented cancer immunotherapy [0.03%]
用于靶向药物输送和增强癌症免疫治疗的敏化肥大细胞

Yan Xu et al.
Cell-mediated drug-delivery systems have garnered significant attention for their potential to boost therapeutic efficacy in cancer treatment. Here, we engineered immunoglobulin E (IgE)-sensitized mast cells (IgE-MCs) to achieve antigen-gui...
Multimodal AI generates virtual population for tumor microenvironment modeling [0.03%]

Microtubules have long been recognized as upstream mediators of intracellular signaling, but the mechanisms underlying this fundamental function remain elusive. Here, we identify the structural basis by which microtubules regulate the guani...
Biomaterial-minimalistic photoactivated bioprinting of cell-dense tissues [0.03%]
用于密集细胞组织光激活生物打印的生物材料极简主义方法

Mian Wang et al.
Conventional hydrogel-based bioprinting methods often suffer from insufficient cell densities, which may limit crucial cell-cell interactions and impair overall tissue functions. Here, we present an approach that modifies cell membranes wit...
Psilocybin triggers an activity-dependent rewiring of large-scale cortical networks [0.03%]
裸盖菇素诱发皮层网络的活动依赖性重塑

Quan Jiang et al.
Psilocybin holds promise as a treatment for mental illnesses. One dose of psilocybin induces structural remodeling of dendritic spines in the medial frontal cortex in mice. The dendritic spines would be innervated by presynaptic neurons, bu...
Autoantibody-triggered podocyte membrane budding drives autoimmune kidney disease [0.03%]
自身抗体诱发的足细胞膜芽突起驱动自身免疫性肾脏病
Karen Lahme,Wiebke Sachs,Sarah Froembling et al.
Karen Lahme et al.
Chronic kidney disease affects 1 in 10 people worldwide, with damage to specialized blood filter cells of the kidney, called podocytes, playing a critical role. In membranous nephropathy (MN), a major cause of nephrotic syndrome, circulatin...
A fin-loop-like structure in GPX4 underlies neuroprotection from ferroptosis [0.03%]
GPX4中的一个类似fin-loop的结构可介导铁死亡下的神经保护作用
Svenja M Lorenz,Adam Wahida,Mark J Bostock et al.
Svenja M Lorenz et al.
Ferroptosis, driven by uncontrolled peroxidation of membrane phospholipids, is distinct from other cell death modalities because it lacks an initiating signal and is surveilled by endogenous antioxidant defenses. Glutathione peroxidase 4 (G...
