by

J Clin Immunol. 2025 Oct 16;45(1):143. doi: 10.1007/s10875-025-01949-0. ABSTRACT Hypogammaglobulinemia (HG) predisposes patients to gastrointestinal Campylobacter infections. This prospective study determined the prevalence of Campylobacter in stool samples from patients with immunoglobulin (Ig)-substituted HG at Bordeaux University Hospital. 73 patients (42 women, median age: 61) receiving Ig substitution therapy were enrolled from July 2022 to … Read more

Epstein-Barr Virus-Associated Smooth Muscle Tumors in inborn Errors of Immunity: A single-center Case Series and Literature Overview

by

J Clin Immunol. 2025 Oct 16;45(1):144. doi: 10.1007/s10875-025-01936-5. ABSTRACT BACKGROUND: Primary immunodeficiency disease (PID)/Inborn Errors of Immunity (IEI) with T-cell dysfunction is well-known for susceptibility to opportunistic/viral infections. Epstein-Barr virus-positive smooth muscle tumor (EBV-SMT) is a rare entity primarily seen in the setting of immunodeficiency, such as transplantation, HIV/AIDS, and IEI. AIM: This study aimed … Read more

Extracellular HMGB1 impairs macrophage phagocytosis and promotes salivary gland dysfunction in Sjogren’s syndrome

by

J Immunol. 2025 Oct 14:vkaf225. doi: 10.1093/jimmun/vkaf225. Online ahead of print. ABSTRACT Impaired phagocytosis of macrophages was observed in the salivary glands (SGs) of Sjogren’s syndrome (SS). This study aims to investigate the dynamic changes of extracellular high mobility group box 1 (HMGB1) within these tissue microenvironments and its roles in macrophage function and subsequent … Read more

Organic cation transporter 1 participates in the immune response of Pinctada fucata martensii by regulating nAChR

by

J Immunol. 2025 Oct 15:vkaf158. doi: 10.1093/jimmun/vkaf158. Online ahead of print. ABSTRACT Pinctada fucata martensii is an economically important mollusk in aquaculture, known for marine pearl production. The inflammatory response during the transplantation process was a key factor affecting pearl yield. Our previous studies have revealed the critical role of nicotinic acetylcholine receptors (nAChRs) from … Read more

The Regulatory Effects of Hypoxic Environment on Neutrophil Function and the Related Molecular Mechanisms​Yun-Chen Zhu on 15 de October de 2025 at 10:00

by

J Leukoc Biol. 2025 Oct 14:qiaf144. doi: 10.1093/jleuko/qiaf144. Online ahead of print. ABSTRACT Metabolic remodeling is involved in multiple diseases, including tumors, acute and chronic inflammations, but our understanding of the molecular pathways remains limited. Neutrophils, as pivotal effector cells of the innate immune system, exhibit significant functional heterogeneity influenced by the hypoxic microenvironment, a … Read more

Treating sarcoidosis: when less is more

by

Curr Opin Immunol. 2025 Oct 13;97:102679. doi: 10.1016/j.coi.2025.102679. Online ahead of print. ABSTRACT Sarcoidosis is a heterogeneous condition, with some presentations associated with spontaneous remission and favourable outcome without treatment. Other presentations, including small fibre neuropathy, arthropathy and sarcoid-associated fatigue, can cause disabling symptoms that may not respond to disease-modifying therapies and must be managed … Read more

B-cell subsets have different capacities for phagocytosis and subsequent presentation of antigen to cognate T cells

by

J Immunol. 2025 Oct 13:vkaf282. doi: 10.1093/jimmun/vkaf282. Online ahead of print. ABSTRACT B cells have been shown to be phagocytic under some circumstances. However, the phagocytic capacity of different B-cell subsets and how this is linked to antigen (Ag) presentation or other functions has not been characterized. To address this, we developed 2-µm phagocytic Ag-conjugated … Read more

Single-cell clonal lineage tracing identifies the transcriptional program controlling the cell-fate decisions by neoantigen-specific CD8+ T cells

by

Cancer Immunol Res. 2025 Oct 13. doi: 10.1158/2326-6066.CIR-25-0203. Online ahead of print. ABSTRACT Neoantigen-specific T cells recognize tumor cells and are critical for cancer immunotherapies to be effective. However, the transcriptional program controlling the cell-fate decisions by neoantigen-specific T cells is incompletely understood. Here, using joint single-cell transcriptome and T-cell receptor (TCR) profiling, we mapped … Read more

IL-2/IL-15 signaling induces NK cell production of FLT3LG augmenting anti-PD-1 immunotherapy

by

Cancer Immunol Res. 2025 Oct 13. doi: 10.1158/2326-6066.CIR-24-1259. Online ahead of print. ABSTRACT Natural killer (NK) cells play a critical role in anti-cancer immunity through their direct cytotoxicity and production of cytokines, such as Flt3L. NK cell production of Flt3L controls conventional type I dendritic cell (cDC1) abundance in the tumor and promotes protective immune … Read more

Interferon-sensitized hematopoietic progenitors dynamically alter organismal immunity

by

J Immunol. 2025 Oct 12:vkaf249. doi: 10.1093/jimmun/vkaf249. Online ahead of print. ABSTRACT Inflammation has enduring impacts on organismal immunity. However, the precise mechanisms by which tissue-restricted inflammation conditions systemic responses are poorly understood. Here, we leveraged a highly compartmentalized model of skin inflammation and identified a surprising type I interferon (IFN)-mediated activation of hematopoietic stem/progenitor … Read more
