Pyroptotic cell corpses are crowned with F-actin-rich filopodia that engage CLEC9A signaling in incoming dendritic cells

Holley et al. investigated the morphological changes during pyroptotic cell death, and identified that inflammasome activation induces F-actin-rich filopodia formation before plasma membrane rupture. ...

Chemotherapy induces myeloid-driven spatially confined T cell exhaustion in ovarian cancer

Launonen et al. explored the dynamic remodeling of HGSC TME under platinum-based chemotherapy and identified myelonets – spatially confined networks of interconnected myeloid cells – as key drivers of...

Intratumoral delivery of lipid nanoparticle-formulated mRNA encoding IL-21, IL-7, and 4-1BBL induces systemic anti-tumor immunity

Hamouda et al. engineered LNPs with an ionizable cationic lipid S-Ac7-DOG to improve levels of cargo expression and reduce reactogenicity. Intratumoral (i.t.) delivery of such LNPs, comprising a trio ...

Oxidized mRNA Lipid Nanoparticles for In Situ Chimeric Antigen Receptor Monocyte Engineering

To optimize mRNA delivery to monocytes in vivo, Mukalel et al. generated oxidized (o) and unoxidized (u) LNPs. Compared to uLNPs, oLNPs differed in charge and morphology, improved mRNA delivery to mac...

Rab8a restores youthful function in DCs from aged mice

December 11, 2024

With advanced age comes impaired immunity and thus, increased susceptibility to diseases, including infections and cancer. Investigating factors that contribute to this reduced immune functionality, Singh et al. evaluated splenic and bone marrow-derived DCs and found that in aged...

CD73 and PD-1 gatekeep self-reactive CD4+ T cell expansion

December 4, 2024

T cell tolerance to self antigens is essential for the prevention of autoreactivity, and negative selection in the thymus is partially responsible for this process. However, at least one-third of CD4+ T cells reactive to a self antigen escape...

A tetraspecific NK cell engager armed with IL-2v targets B-NHL

November 27, 2024

To capitalize on the antitumor potential of NK cells for the treatment of B cell non-Hodgkin lymphoma (B-NHL), Demaria et al. developed a clinical-grade tetraspecific NK cell engager (NKCE) that targets NKp46 and CD16a on NK cells and CD2...
