Response to anti-PD-1 in patients with hepatocellular carcinoma is associated with clonal expansion of intratumoral CXCL13⁺ CD4⁺ helper T cells and effector-like CD8⁺ T cells, and local dendritic cells enriched in expression of maturation and regulatory molecules help facilitate CD8⁺ T cell differentiation.

“Genome-wide association studies have identified variants associated with age-related macular degeneration (AMD); however, other than identifying this as a complement mediated inflammatory disease, little biology has emerged. Here, authors used novel computational tools from the Broad Institute to examine the relationship of single-cell transcriptomics and genome-wide association studies (GWAS) in the human retina and demonstrate that GWAS-associated risk alleles associated with AMD are enriched in glia and vascular cells and that human retinal glia are more diverse than previously thought

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.

DNA double strand breaks (DSBs) are among the most deleterious types of damage and there is strong evidence indicating a relationship between breaks and transcription. Here the authors provide a high-resolution, genome-wide map of induced DSBs and observe ATM-dependent transcriptional repression.

Information flow in the cortex is usually thought to be subserved by direct, cortico-cortical connections.

PD-1 is a critical modulator of CD8⁺ T cell activation and exhaustion. Sen and colleagues show that a cell-state-specific enhancer tunes PD-1 expression exclusively in exhaustion and that deletion of this enhancer improves CD8⁺ T cell function.

Multi-omics profiling of the blood and heart of two human decedents receiving pig heart xenografts, including single-cell studies, reveals early immune responses and perioperative cardiac xenograft dysfunction in one of the two decedents, which may be due to mismatched heart size and/or insufficient immunosuppression.

Injection of AAV–shRNA below the pial surface of the spinal cord prevents onset or ameliorates progression in a mouse model of ALS, and achieves widespread delivery to the spinal cord and brain motor centers in adult pigs and non-human primates.

Characterization of DCAF16-based BRD4 molecular glue degraders revealed a trans-labeling mechanism termed ‘template-assisted covalent modification’, which opens a new path for proximity-driven pharmacology.

Synthetic Notch (synNotch) receptors are genetically encoded, modular synthetic receptors that enable mammalian cells to detect environmental signals and respond by activating user-prescribed transcriptional programs. Here the authors apply synNotch receptors to spatially control differentiation of endothelial and skeletal muscle cells in a multicellular construct on assorted biomaterials.

Zhang et al. show that bone marrow fatty acid metabolism fuels expanded leukocyte production after myocardial infarction and, based on mouse, pig and human data, suggest that lipolysis in marrow adipocytes provides fatty acids to hematopoietic stem cells.

De novo designed interleukin-4 mimetics were engineered that induce biased signaling activation and exhibit high thermal stability. These mimetics offer insight into cytokine signaling and can be directly incorporated into 3D-printed biomaterials

Industry research funding is vastly eclipsing academia’s spend, but healthy development demands broad input.
