The Pathogenic Role of Expanded CD8⁺CD28 Angiogenic T Cells in ANCA-Associated Vasculitis.

Biomedicines

December 2024

Department of Clinical Immunology of Xijing Hospital and Department of Cell Biology of National Translational Science Center for Molecular Medicine, Fourth Military Medical University, Xi'an 710032, China.

Angiogenic T cells (Tang) are crucial in promoting angiogenesis, with the loss of CD28 serving as a marker for highly differentiated and senescent T cells. This study aims to investigate the characteristics and potential roles of CD8CD28 Tang in patients with ANCA-associated vasculitis (AAV). A cohort of AAV patients and matched healthy controls (HCs) were analyzed.

Enniatins (ENNs) affect human and animal health. Different ENN analogs have been identified, but Enniatin B (ENN B) is the most detected in foods and feeds. This study investigated the effect of ENN B on bovine polymorphonuclear leukocytes (PMNs) challenged with increasing ENN B concentrations (0.

This study evaluates the effects of liraglutide on albuminuria, oxidative stress, and inflammation in type 2 diabetes (T2D) patients with different urinary albumin-to-creatinine ratio (UACR) categories. We enrolled 107 patients with T2D who were initiating liraglutide for glycemic control. Patients were categorized into 3 groups: group I (UACR < 30 mg/g); group II (30 mg/g ≤ UACR ≤ 300 mg/g); group III (UACR > 300 mg/g).

A novel patient group with chronic pulmonary fibrosis is emerging post COVID-19. To identify patients at risk of developing post-COVID-19 lung fibrosis, we here aimed to identify systemic proteins that overlap with fibrotic markers identified in patients with idiopathic pulmonary fibrosis (IPF) and may predict COVID-19-induced lung fibrosis. Ninety-two proteins were measured in plasma samples from hospitalized patients with moderate and severe COVID-19 in Sweden, before the introduction of the vaccination program, as well as from healthy individuals.

Disrupting EDEM3-induced M2-like macrophage trafficking by glucose restriction overcomes resistance to PD-1/PD-L1 blockade.

Clin Transl Med

January 2025

Department of General Surgery (Colorectal Surgery), The Sixth Affiliated Hospital, Sun Yat-sen University, Guangzhou, Guangdong, China.

Background: Immunotherapy is beneficial for some colorectal cancer (CRC) patients, but immunosuppressive networks limit its effectiveness. Cancer-associatedfibroblasts (CAFs) are significant in immune escape and resistance toimmunotherapy, emphasizing the urgent need for new treatment strategies.

Methods: Flow cytometric, Western blotting, proteomics analysis, analysis of public database data, genetically modified cell line models, T cell coculture, crystal violetstaining, ELISA, metabonomic and clinical tumour samples were conducted to assess the role of EDEM3 in immune escape and itsmolecular mechanisms.
