Remodeling of the Immune and Stromal Cell Compartment by PD-1 Blockade in Mismatch Repair-Deficient Colorectal Cancer

[Cancer Cell] Researchers utilized single-cell RNA sequencing to investigate the dynamics of immune and stromal cells in 19 patients with mismatch repair-deficient and microsatellite instability-high colorectal cancers who received neoadjuvant PD-1 blockade.

Single Cell Profiling at the Maternal–Fetal Interface Reveals a Deficiency of PD-L1+ Non-Immune Cells in Human Spontaneous Preterm Labor

[Scientific Reports] Among the immune cells, maternal PD1+ CD8 T cell subsets were less abundant in term laboring compared to term non-laboring women.

Anti-GD2 CAR-NKT Cells in Relapsed or Refractory Neuroblastoma: Updated Phase I Trial Interim Results

[Nature Medicine] Investigators reported updated interim results from the first-in-human phase I evaluation of autologous natural killer T cells (NKTs) co-expressing a GD2-specific chimeric antigen receptors (CAR) with interleukin 15 in 12 children with neuroblastoma.

Early Alterations in the MCH System Link Aberrant Neuronal Activity and Sleep Disturbances in a Mouse Model of Alzheimer’s Disease

[Nature Neuroscience] Researchers showed that melanin-concentrating hormone (MCH) downregulated synaptic transmission, modulated firing rate homeostasis in hippocampal neurons, and reversed the increased excitatory drive to CA1 neurons in AppNL-G-F mice.

GAP43-Dependent Mitochondria Transfer From Astrocytes Enhances Glioblastoma Tumorigenicity

[Nature Cancer] Investigators showed that mitochondria transfer is a prevalent phenomenon in glioblastoma (GBM). They identified horizontal mitochondria transfer from astrocytes as a mechanism that enhances tumorigenesis in GBM.

Circulating Tumor DNA Reveals Mechanisms of Lorlatinib Resistance in Patients With Relapsed/Refractory ALK-Driven Neuroblastoma

[Nature Communications] Scientists established the clinical utility of serial circulating tumor DNA sampling to track response and progression and discover acquired resistance mechanisms that can be leveraged to develop therapeutic strategies to overcome lorlatinib resistance.
