Purpose: Glioblastoma (GBM) that presents as leptomeningeal disease (LMD) is extremely rare and fatal. Limited data are available regarding incidence, clinical presentation, and management. Prognosis is poor and no treatment is known to improve survival.

Article Synopsis
  • Glioblastoma (GBM) is a highly malignant tumor with poor patient prognosis, displaying features like necrosis and abnormal blood vessel growth.
  • This study employed single-cell RNA sequencing and spatial transcriptomics to analyze the microenvironment of GBM in three patients, revealing distinct spatial segregation of tumor cell states, particularly between OPC-like and NPC-like cells.
  • The analysis identified unique gene expression patterns and pathways, indicating that perinecrotic areas are more immunosuppressive while perivascular regions are pro-inflammatory, suggesting a relationship between tumor cell localization and their oxygen needs.

We present the solution-state NMR structures and preliminary functional characterizations of three venom peptides identified from the spitting spider Scytodes thoracica. Despite little sequence identity to other venom peptides, structural characterization reveals that these peptides contain an inhibitor cystine knot motif common to many venom peptides. These are the first structures for any peptide or protein from spiders of the Scytodidae family.

By 24 h after infection with human cytomegalovirus, the reticular mitochondrial network characteristic of uninfected fibroblasts was disrupted as mitochondria became punctate and dispersed. These alterations were associated with expression of the immediate-early (alpha) antiapoptotic UL37x1 gene product viral mitochondrion-localized inhibitor of apoptosis (vMIA). Similar alterations in mitochondrial morphology were induced directly by vMIA in transfected cells.
