High altitude characterized by the low partial pressure of the oxygen is a life-threatening condition that contributes to the development of acute pulmonary edema and hypoxic lung injury. In this study, we aimed to investigate the contribution of some inflammatory and oxidative stress markers along with antioxidant system enzymes in the pathogenesis of HAPE (high-altitude pulmonary edema) formation. We incorporated the study on 42 male rats to unravel the role of mast cells (MCs) and TNF-α in the lung after the effect of acute hypobaric hypoxia.

A mixed phenotype is characteristic of de novo Mixed Phenotype Acute Leukemia (MPAL) but can also be seen in other leukemias. It poses substantial classification and management dilemmas. Herein, we report a large cohort of acute leukemia with a mixed phenotype and define Acute Myeloid Leukemia with Mixed Phenotype (AML-MP) and MPAL as two distinct groups by characterizing the clinical, genetic, and transcriptomic features.

Its common germline variants APOE2, APOE3 and APOE4 give rise to three functionally distinct gene products. Previous studies reported yin-yang roles of APOE2 and APOE4 in immunological processes, but their effects in hematopoietic stem cell transplantation (HSCT) have never been studied.

T-cell receptor (TCR) therapies are a promising modality for the treatment of cancers, with significant efforts being directed towards acute myeloid leukaemia (AML), a particularly challenging disease. Chimeric antigen receptor (CAR) T-cells targeting single surface antigens have shown remarkable efficacy for B-cell lymphoblastic leukaemia, lymphomas and multiple myeloma. However, AML presents formidable obstacles to the effectiveness of CAR T-cells due to the widespread expression of heterogenous leukaemia immunophenotypes and surface antigen targets additionally present on normal myeloid cells.
