NKG2D provides a costimulatory signal for activation of CD4+ T cells. We explored its role in interactions of CD4+ T cells and dendritic cells (DCs) in juvenile idiopathic arthritis (JIA) patients by using NKG2D genetically modified CD4+ T cells. We found active JIA patients had significantly higher content of CD4 + NKG2D+ T cells than healthy controls. Expression of NKG2D on CD4+ T cells, and MICA and MICB on DCs were significantly greater in articular JIA than systemic JIA. NKG2D induced IL- 12 and suppressed IL-10 and TGF-β from CD4+ T cells, increased IFN-γ + CD4+ T and IL-17+ CD4+ T cells, RORc and T-bet, but reduced CD25+ Foxp3+ CD4+ T cells, IL-4+ CD4+ T cells, Foxp3, and GATA3 in JIA patients. NKG2D decreased IL-10 and increased CD83, MICA, and MICB of DCs in JIA and controls. So NKG2D regulates differentiation of CD4+ T cells directly and the maturation of DCs indirectly.

Background: Breast cancer is a systemic disease, yet the impact of tumor molecular subtype and disease stage on the systemic immune landscape remains poorly understood. In this study, we comprehensively analyzed the systemic immune landscape in a large cohort of breast cancer patients, encompassing all molecular subtypes and disease stages, alongside a control group of healthy donors.
Materials And Methods: Using multi-parameter flow cytometry, we assessed the abundance, phenotype, and activation status of diverse innate and adaptive immune cell populations across peripheral blood samples from 355 breast cancer patients and 65 healthy donors.

Background: Recombinant human thrombopoietin (rhTPO) regulates platelet production by promoting megakaryocyte proliferation and has shown promising therapeutic effects in hematopoietic recovery for severe aplastic anemia (SAA). However, its potential impact on immune cells remains unclear.
Methods: This study included 23 patients with SAA, who were divided into two groups based on whether they received rhTPO.

In patients with advanced urothelial carcinoma who have progressed after platinum-based chemotherapy, enfortumab vedotin (EV) improves overall survival compared to standard chemotherapy. Additionally, for treatment-naïve patients with locally advanced or metastatic urothelial carcinoma, the combination of pembrolizumab and EV demonstrates superior efficacy over platinum-based chemotherapy. Hence, EV becomes a standard treatment option.

Periodontitis, a pervasive chronic inflammatory disorder, is distinguished by the progressive degradation of periodontal tissues and alveolar bone. Despite remarkable progress in understanding the pathogenesis of periodontitis, the involvement of TCRαβCD4CD8 T cells, also known as double-negative T (DNT) cells, in the pathophysiology of this disease has not been thoroughly investigated. In this study, we observed a significant reduction in the frequency of TCRαβ DNT cells within the gingival tissues of patients afflicted with periodontitis when compared with healthy individuals.

Background: Alzheimer's disease (AD) patients and animal models exhibit an altered gut microbiome that is associated with pathological changes in the brain. Intestinal miRNA enters bacteria and regulates bacterial metabolism and proliferation. This study aimed to investigate whether the manipulation of miRNA could alter the gut microbiome and AD pathologies.
