The fibrinolytic system promotes the progression of solid tumors. Here, the authors show that the fibrinolytic agent plasmin supports B-cell acute lymphoblastic leukemia (B-ALL) progression via remodeling of the extracellular matrix, and the inhibition of plasmin activation with ε-aminocaproic acid prolongs survival in B-ALL mouse models.

Fibroblasts from old mice are heterogeneous, which affects the ability of these fibroblasts to reprogram into induced pluripotent stem cells in vitro and influences wound healing rate in vivo.

Re-exposure to a high-fat diet in mice led to emergency myelopoiesis and increased neutrophils in the blood, which infiltrated plaques and released neutrophil extracellular traps, exacerbating atherosclerosis.

IL-33 induces tertiary lymphoid structures.

Kozai, Fernandez-Martinez et al. use high-speed atomic force microscopy to study the permeability barrier of yeast nuclear pore complexes. They show that karyopherins remodel a central plug that shapes barrier dynamics and disorder within the pore.

Here the authors provide an explanation for 95% of examined predicted loss of function variants found in disease-associated haploinsufficient genes in the Genome Aggregation Database (gnomAD), underscoring the power of the presented analysis to minimize false assignments of disease risk.

Here, the authors show how in β-thalassemia, a perturbed bone marrow microenvironment leads to altered hematopoiesis. Reduced TGFβ reduces autophagy levels, in turn reducing dormancy and priming of haematopoietic stem cells and multipotent progenitors towards erythroid lineage.

JMML is an aggressive hematologic malignancy with myeloproliferative characteristics affecting young children. Here the authors report that C-type lectin-like molecule-1 (CLL-1) is upregulated in JMML and they develop CLL-1 CAR T cells showing in vitro and in vivo anti-JMML activity.

Primary angle-closure glaucoma can cause blindness. Here, the authors study populations of Asian and European ancestries and find that genetic factors associated with darker irises and being far sighted increase the risk of developing the condition.

Glioblastoma—the deadliest form of brain cancer—alters the calvarial bone and its marrow components, pushing it toward producing more myeloid cells and contributing to an immunosuppressive environment.

Fibroblasts represent a heterogenous cell population but how their differences reflect their plasticity and origin is not fully understood. Here, the authors map the origin and fate of a transient contractile fibroblast population that forms a niche supporting pubertal mammary gland branching and growth.

Extensive characterization of the stem and progenitor cell hierarchies of myelodysplastic syndromes reveals compensatory survival mechanisms underpinning the failure of hypomethylating agents, and uncovers biomarkers that predict second-line clinical response to venetoclax-based therapy.

A simple transport model infers a material’s electronic dimensionality from standard transport measurements, revealing temperature-, doping- and alloying-driven shifts between low-dimensional and 3D transport in SrTiO₃, Bi₂O₂Se and Pb_1-xSn_xTe.

Ionic liquid additives increase the power conversion efficiency of perovskite solar cells, but their effect on perovskite crystallization remains unclear. Xu et al. provide mechanistic insights and demonstrate improved operational stability under continous illumination and 90 °C thermal stress.

The role of mosquito saliva proteins in viral infection remains incompletely understood. Here, the authors show that sialokinin facilitates viral dissemination while suppressing immune response and inflammation in chikungunya virus-infected mice.

Diamond Blackfan Anemia (DBA) is a congenital bone marrow failure syndrome that is associated with anemia. Here, the authors examine the role of Nemo-like kinase (NLK) in erythroid cells in the pathogenesis of DBA and as a potential target for therapy.

Polymerization reactions are often catalysed by metal compounds and hence there are concerns surrounding toxicity, cost and environmental friendliness. Here the authors show sulfenate anions as organocatalysts for benzylic chloromethyl-coupling polymerization reactions to form poly(stilbene)s.

The heterogeneity of HSPCs in response to IR stress remains poorly characterized. Here, the authors provide insights into the molecular intricacies of IR-induced BM injury and reveal the roles of BMP4-BMPR2 signaling in radiation resistance of HSCs.

Ferroptotic propagation aggravates kidney ischemia-reperfusion injury and causes delayed graft function. Here, the authors show that inhibiting lactate shuttle and AARS1-mediated NPM1 lactylation protects graft function by blocking ferroptotic waves.
