NASA Study: Mouse Blood Biomarkers for Deep Space Radiation Cognitive Effects

Flow cytometry blood assay data from a NASA study on galactic cosmic radiation (GCR) effects on cognitive performance in mice. The dataset likely contains measurements related to blood monocyte levels, microglia activation, and synaptic alterations, used to identify sex-dimorphic responses and potential countermeasures. Data was last updated on March 13, 2026.

Use Cases

• Predicting late cognitive deficits based on early blood monocyte levels mentioned in the description
• Analyzing sex-dimorphic responses to simulated galactic cosmic radiation (GCRsim) described in the study
• Investigating correlations between peripheral biomarkers and chronic microglia activation in the hippocampus
• Evaluating potential therapeutic strategies for mitigating radiation-induced cognitive loss

Strengths

• Data originates from NASA, a leading authority in space research
• Study design includes multivariate principal components analysis and links to related behavioral and histological datasets (OSD-479, OSD-777, OSD-778)
• Last updated on 2026-03-13, indicating recent maintenance

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is derived from a mouse model; applicability to humans requires further validation
