Adult T-cell leukemia (ATL) occurs in human T-lymphotropic virus type I-infected individuals and is endemic to the southwestern area of Kyushu in Japan. Here, we found that nM levels of genistein and 17β-estradiol had cytotoxic effects on ATL cells and activated caspase-3. The estrogen receptor antagonist ICI182780 negated the cytotoxic effect of genistein. In addition, G protein-coupled estrogen receptor agonist G-1 also had a cytotoxic effect on ATL cells. This is the first report suggesting that estrogen receptors are a molecular target for ATL therapy.

Reduced function or hypomorphic variants in recombination-activating genes (RAG) 1 or 2 result in a broad clinical phenotype including common variable immunodeficiency (CVID) and even adult-onset disease. Milder RAG variants are less characterized. Here we describe the longitudinal course of a milder combined RAG deficiency in 3 of 7 siblings sharing the same RAG2 mutations over a 50-year study.

Particulate matter (PM) exposure has been proposed as one of the causes of steroid resistance. However, studies investigating this using patient samples or animals are still lacking. Therefore, in this study, we aimed to investigate the changes in cytokines and mTOR (mammalian target of rapamycin) activation in patients with steroid resistant asthma and the role of mTOR in a mouse model of steroid resistant asthma induced by PM.

Previous reports have indicated that during the era of combination antiretroviral therapy, the major causes of morbidity and mortality in people living with HIV (PLWH) were not solely linked to HIV-related opportunistic infections but also to cancers that were difficult to manage due to HIV-related immunodeficiency. We investigated whether PLWH who underwent autologous hematopoietic stem cell transplantation (ASCT) for lymphomas experienced significant morbidity over the past thirty years following HIV infection. We conducted a retrospective follow-up study of 49 PLWH over a 10-year period following ASCT.

Background: Synchronous malignant histiocytoses are rare conditions that occur concurrently with another hematologic neoplasm. Most reported cases are associated with B-cell lymphoproliferative disorders, while associations with T-cell hemopathies are less common. These two diseases may share mutations and/or cytogenetic anomalies, which can lead to malignant proliferations.

B cells have emerged as central players in the tumor microenvironment (TME) of non-small cell lung cancer (NSCLC). However, although there is clear evidence for their involvement in cancer immunity, scanty data exist on the characterization of B cell phenotypes, bioenergetic profiles and possible interactions with T cells in the context of NSCLC. In this study, using polychromatic flow cytometry, mass cytometry, and spatial transcriptomics we explored the intricate landscape of B cell phenotypes, bioenergetics, and their interaction with T cells in NSCLC.
