Article Synopsis
  • High-dimensional technologies like CyTOF imaging mass cytometry (IMC) analyze the spatial arrangement of cancer and immune cells in tumor samples before immunotherapy, providing insights into their organization in the tumor microenvironment (TME).
  • A new model developed using IMC data from melanoma patients undergoing ICI therapy reveals that the spatial relationships between activated CD8 T cells, macrophages, and melanoma cells significantly influence tumor growth and patient outcomes.
  • Key findings highlight that the initial spatial configuration of these immune cells predicts tumor progression, with features like the co-clustering of activated CD8 T cells and macrophages being critical, despite variations during treatment.

Traumatic brain injury (TBI) is a risk factor for neurodegenerative disease. We currently have no means to identify patients most at risk of neurodegenerative disease following injury and, resultantly, no means to target risk mitigation interventions. To address this, we explored the association between history of traumatic brain injury with cognitive performance and imaging measures of white matter integrity.

Diet selection and composition of sheep target grazing plains larkspur ( Greene) in northern mixed-grass prairie were evaluated during a drought year (2022). Thirteen Rambouillet ewes (3-to 6-year-old, body weight (BW) 76 kg ± 2.9), 14 Dorper ewes (3-to 6-year-old, BW 47 kg ± 1.

Importance: Elite-level contact sport participation is associated with increased dementia risk, which may be attributable to sport-related traumatic brain injury and repetitive head impact exposure. However, the contribution of wider, potentially modifiable dementia risk factors remains uncertain.

Objective: To explore the association of potentially modifiable dementia risk factors with dementia risk among former professional soccer players.

Chronic exposure of the liver to multiple insults culminates in the development of metabolic dysfunctionassociated steatohepatitis (MASH), a complicated metabolic syndrome characterized by hepatic steatosis and inflammation, typically accompanied by progressive fibrosis. Despite extensive clinical evaluation, there remain challenges in MASH drug development, which are primarily due to unsatisfactory efficacy and limited specificity. Strategies to address the unmet medical need for MASH with fibrosis before it reaches the irreversible stage of decompensated cirrhosis are critically needed.
