- Restoring antitumor immunity while enhancing the chemotherapy efficacy represents an optimistic strategy for cancer treatment. Enabling macrophage-mediated phagocytosis of cancer cells is pivotal for rehabilitating effective immune responses. However, its efficacy is often limited by elevated anti-phagocytic signals, such as CD47, and insufficient pro-phagocytic signals on cancer cells. We employed a synergic chemo-immunotherapeutic approach involving the chemotherapeutic agent doxorubicin (DOX) together with siRNA targeting CD47 (siCD47), co-delivered by a bola-amphiphilic dendrimer (bola4A) as a nanocarrier. The co-delivery system (bola4A/DOX/siCD47) was established by encapsulating DOX within the hydrophobic interior of dendrimer nanomicelles, while complexing the negatively charged siCD47 to the positively charged dendrimer surface. The bola4A/DOX/siCD47 effectively downregulated CD47 expression and attenuated the CD47-signal regulatory protein α (SIRPα) axis-mediated anti-phagocytic signal. Concurrently, DOX induced immunogenic cell death (ICD) and significantly increased the exposure of calreticulin (CALR), a pro-phagocytic signal that elicits immune response. Consequently, bola4A/DOX/siCD47 enhanced phagocytosis of tumor cells by macrophages and reprogrammed the tumor immunosuppressive microenvironment (TME) towards enhanced macrophage phagocytosis, dendritic cell maturation, T cell infiltration, and elevated secretion of pro-inflammatory cytokines. Altogether, bola4A/DOX/siCD47 exhibited a potent antitumor effect through the coordinated action of DOX with siCD47 and offers a promising approach for synergistic cancer chemo-immunotherapy. - Source: PubMed

Lian BaopingZhu DandanChen PengWang ZhihuiMeng FanzhenYan RanPyataev Nikolay ALiu Xiaoxuan - Philadelphia-negative myeloproliferative neoplasms (MPNs) can progress to blast phase (MPN-BP), a biologically distinct and highly lethal entity with a median survival typically under six months. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only potentially curative approach, yet relapse and non-relapse mortality limit durable benefit. We retrospectively analyzed post-transplant outcomes in 51 consecutive adults undergoing 53 allo-HSCTs for MPN-BP. Median age was 62 years; most cases evolved from myelofibrosis, and JAK2 was the predominant driver mutation. Neutrophil engraftment occurred in all but two patients (median 12 days). At 1-year, cumulative incidences were 35.8% for grade II-IV acute GVHD, 7.5% for moderate-severe chronic GVHD, 44.3% for relapse, and 25.8% for non-relapse mortality. One-year overall survival (OS) and disease-free survival were 43.4% and 37.7%, respectively; relapse was the leading cause of death. In multivariable analysis, TP53 mutations and higher peripheral blast burden adversely affected OS, while CALR mutations appeared to be associated with improved OS, peripheral blasts also independently predicted relapse. These data underscore the cure rate of approximately one-third of MPN-BP and highlight peripheral blasts and TP53 as actionable risk markers for transplant strategies. - Source: PubMed

Liu ZhenLi XiongzhiGuo QianqianLi GuangyuSun HongmeiZou JiangbinXing BaoruiAkhtar Rana WaseemGuo YingyanZhao Haiping - Triple-negative breast cancer (TNBC) with bone metastasis is challenging to treat due to an immunosuppressive microenvironment and the limited, transient immune activation from conventional external beam radiotherapy. Inducing immunogenic cell death (ICD) offers a strategy to remodel this environment, but its systemic effects remain to be validated. Here, we investigate iodine-125 (I) brachytherapy as a method to induce sustained ICD and activate systemic antitumor immunity in TNBC bone metastasis using transcriptomic analysis, a dual-tumor model, and CALR-targeted molecular imaging. - Source: PubMed

Li MinCui ZhenzhenYang JiaxinSun QiyuHu YanboShen JuanLi ZhihaoHan XiaoyangWang YixuanTang JiagengYu HengsongMa XiaowenWang Jing - Splanchnic vein thrombosis (SVT) is a rare, life-threatening condition that is often associated with cirrhosis, pancreatic malignancy and thrombophilia. Myeloproliferative neoplasms are under-recognised causes, posing diagnostic challenges. In this case, we present a male in his late 20s with a history of unprovoked pulmonary embolism and portal/splenic vein thrombosis, on indefinite anticoagulation therapy presenting 3 years later due to abdominal pain. Imaging revealed cirrhosis, cavernous transformation of the main portal vein and splenomegaly. These findings and a prior negative hypercoagulability workup prompted haematology consultation. Bone marrow biopsy confirmed primary myelofibrosis (PMF), demonstrating 90% cellularity, megakaryocytic hyperplasia, MF-3 fibrosis and calreticulin (CALR) mutation. This case underscores PMF as a treatable cause of SVT in young patients with recurrent thrombosis and highlights the consequences of diagnostic inertia, as marked thrombocytosis at initial presentation was overlooked. When Janus Kinase 2 (JAK2) is negative, CALR testing should be pursued to enable early diagnosis and targeted therapy. - Source: PubMed
