ABSTRACT In tissues, neutrophils neutralize Candida albicans through phagocytosis and delay C. albicans hyphae growth by deploying neutrophil extracellular traps (NETs). However, in the bloodstream, the dynamic interactions between NETs and C. albicans are far less understood. Here, we employ a microfluidic assay … Read more

J Leukoc Biol. 2024 Dec 31:qiae257. doi: 10.1093/jleuko/qiae257. Online ahead of print. ABSTRACT Regulatory T cells can suppress activated T cell proliferation by direct cell-contact, although the exact mechanism is poorly understood. Identification of a Treg-specific cell surface molecule that mediates suppression would offer a unique target for cancer immunotherapy to inhibit Treg immunosuppressive function … Read more

J Leukoc Biol. 2024 Dec 26:qiae259. doi: 10.1093/jleuko/qiae259. Online ahead of print. ABSTRACT Aging significantly increases the incidence and severity of infections, with individuals aged 65 and above accounting for 65% of sepsis cases. Innate immune training, known as “trained immunity” or “innate immune memory”, has emerged as a potential strategy to enhance infection resistance … Read more

J Leukoc Biol. 2024 Dec 26:qiae260. doi: 10.1093/jleuko/qiae260. Online ahead of print. ABSTRACT NR2F6 has emerged as a key player in immune regulation, especially in cancer immunity. It has indeed been reported that NR2F6 could suppress the anti-tumor immune response, and has therefore been suggested as possible target in cancer immunotherapy. In this review, we … Read more

J Leukoc Biol. 2024 Dec 24:qiae258. doi: 10.1093/jleuko/qiae258. Online ahead of print. ABSTRACT INTRODUCTION: Granulocyte concentrates (GC) are leukocyte preparations enriched in neutrophils that can potentially save neutropenic patients from life-threatening, antimicrobial-resistant infections. The main challenge of GC transfusions is preserving the viability and antimicrobial activity of neutrophils beyond 24 h to reduce the logistical … Read more

J Leukoc Biol. 2024 Dec 19:qiae255. doi: 10.1093/jleuko/qiae255. Online ahead of print. ABSTRACT The neutrophil marker CD177 (NB1, HNA-2a) is expressed by 0-100% of circulating neutrophils in any given donor, dividing neutrophils into two distinct subpopulations (CD177pos and CD177neg). High proportions of CD177pos blood neutrophils have been linked to both systemic infections and a range … Read more

J Leukoc Biol. 2024 Dec 17:qiae254. doi: 10.1093/jleuko/qiae254. Online ahead of print. ABSTRACT Psoriasis is a chronic inflammatory skin disease characterized by periods of remission and relapse. In this pathology, keratinocytes, dendritic cells, and different subpopulations of T cells are critical to developing psoriatic lesions. Although current treatments can reduce symptoms, they reappear in previously … Read more

J Leukoc Biol. 2024 Dec 17:qiae253. doi: 10.1093/jleuko/qiae253. Online ahead of print. ABSTRACT While widely viewed as inhibitory receptors that drive efferocytosis and immune resolution on myeloid cells, TAM family members, particularly Mertk, have emerged as promising targets in immune-oncology to help stimulate host anti-tumor immunity. A recent study shows that Mertk expressed on human … Read more

J Leukoc Biol. 2024 Dec 4:qiae251. doi: 10.1093/jleuko/qiae251. Online ahead of print. ABSTRACT γδ T cells play diverse roles in immune responses, producing either IL-17A or IFN-γ. Here we investigated the impact of this functional dichotomy on cutaneous leishmaniasis. We demonstrate that in Sv129 mice susceptible to Leishmania amazonensis, Vγ4+ γδ T cells are the … Read more

J Leukoc Biol. 2024 Nov 28:qiae252. doi: 10.1093/jleuko/qiae252. Online ahead of print. ABSTRACT Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of the coronavirus disease 2019 (COVID-19) pandemic, remains endemic worldwide. Circulating levels of the chemokine CXCL10 are strongly positively associated with poor outcome; however, its precise role in SARS-CoV-2 pathogenesis and its … Read more
