Idiopathic pulmonary fibrosis (IPF) is characterized by excessive extracellular matrix (ECM) deposition driven by aberrant fibroblast-to-myofibroblast transition (FMT). However, the upstream regulators and downstream effectors of this process remain incompletely understood. Here, we identify acyl-CoA synthetase long-chain family member 4 (ACSL4), a lipid metabolic enzyme, as a critical mediator linking complement component 5a (C5a)/C5a receptor 1 (C5aR1) signaling to FMT via calcium signaling.

Cervical squamous cell carcinoma(CSCC) represents formidable challenge in clinical oncology, exacerbated by poor prognosis and resistance to current treatments, including anti-PD-1 therapy, highlighting the urgent need for alternative therapeuties. Metabolic characteristics have emerged as potential drivers of treatment resistance and immune evasion. Herein, 1) based on metabolomic and transcriptomic analyses of 44 CSCC and 18 normal tissues, glutamine-enriched and immunosuppressive microenvironment is identified in CSCC.

Prenyl diphosphate synthase (PDS) plays indispensable roles in terpene biosynthesis. However, there is an ongoing debate regarding whether grape (Vitis vinifera) geranyl diphosphate synthase (VvGDS, VIT_15s0024g00850) can generate geranyl diphosphate (GPP), the precursor of monoterpene biosynthesis. Here, we demonstrated that VvGDS localizes in mitochondria and is an authentic trans-long-chain PDS (thus, VvGDS was renamed VvPDS), which is essential for ubiquinone (UQ) biosynthesis.

Atopic dermatitis (AD) is a chronic and inflammatory disease characterized by skin barrier destruction, sustained inflammation, and immune imbalance. Increasing evidence has suggested mesenchymal stem cells (MSCs) exhibit great potentials in treating AD due to the strong anti-inflammatory, immunomodulatory, and regenerative repair properties. As a cell-free nanocarrier, MSC-derived extracellular vesicles (MSC-EVs) play critical roles in mediating intercellular communications.

Although the programmed cell death protein 1 (PD-1) blockade has been authorized for the treatment of recurrent and metastatic cervical cancer (CC) patients, a significant proportion of CC patients show low objective response rates (ORR) to immune checkpoint blockades (ICBs). Therefore, identifying novel combination treatment strategies to enhance ICBs therapeutic efficacy for CC patients is urgently needed. Here, we discovered that CD39 was highly expressed in exhausted CD8 + T cells from 10 CC patients in our center via single-cell RNA sequencing (scRNA-seq).

B7 homolog 3 (B7-H3) is a member of the B7 ligand family. It is highly expressed in various human cancers, especially mesenchymal malignancies. B7-H3 regulates cancer progression through multiple signaling pathways such as JAK2/STAT3, NF-κB, PI3K/AKT, and ERK.

Polymyositis (PM) is a systemic autoimmune disease characterized by muscular inflammatory infiltrates and degeneration. T-cell immunoreceptor with Ig and ITIM domains (TIGIT) contributes to immune tolerance by inhibiting T cell-mediated autoimmunity. Here, we show that a reduced expression of TIGIT in CD4 T cells from patients with PM promotes these cells' differentiation into Th1 and Th17 cells, which could be rescued by TIGIT overexpression.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent, multifactorial systemic metabolic disorder, now recognized as the most common chronic liver disease globally. Female susceptibility to MASLD varies across menstrual states, influenced by genetic factors, age, menopausal status, and physical activity. Postmenopausal women, experiencing a significant reduction in estrogen, are particularly vulnerable to metabolic imbalances, increasing their risk of MASLD, disease progression, liver fibrosis, insulin resistance, and adverse cardiovascular events compared to premenopausal women and age-matched men.

Imitating the multinodal structures of plants and arthropods, precisely engineered multisegment nanostructures demonstrate enhanced synergistic properties and exceptional functionalities that surpass those of individual components. Utilizing micelle assemblies for constructing segments allows for precise structural control but requires management of interactions and assembly from molecular to mesoscopic levels, posing a significant challenge. In this paper, we present a stepwise self-assembly strategy to fabricate multisegment mesoporous silica (mSiO) nanobamboos.

Montane ecosystems are crucial for maintaining global biodiversity and function that sustain life on our planet. Yet, these ecosystems are highly vulnerable to changing temperatures and may undergo critical transitions under ongoing climate change. What we do not know is to what extent montane biodiversity and ecosystem services will respond to local temperature variations in a gradual versus abrupt manner across global environments.
