Intraoperative brain cancer detection with Raman spectroscopy in humans

…, K Saint-Arnaud, L Bernstein, MC Guiot… - Science translational …, 2015 - science.org
Cancers are often impossible to visually distinguish from normal tissue. This is critical for
brain cancer where residual invasive cancer cells frequently remain after surgery, leading to …

Comparison of polarization properties of human adult microglia and blood‐derived macrophages

…, DA Zammit, TA Johnson, F Zaguia, MC Guiot… - Glia, 2012 - Wiley Online Library
Both microglia, the resident myeloid cells of the CNS parenchyma, and infiltrating blood‐derived
macrophages participate in inflammatory responses in the CNS. Macrophages can be …

[HTML][HTML] Single-cell spatial immune landscapes of primary and metastatic brain tumours

…, DL Senger, JA Chan, L Akkari, K Petrecca, MC Guiot… - Nature, 2023 - nature.com
Single-cell technologies have enabled the characterization of the tumour microenvironment
at unprecedented depth and have revealed vast cellular diversity among tumour cells and …

Sodium-channel defects in benign familial neonatal-infantile seizures

…, A Bleasel, M Shevell, S Mercho, MH Seni, MC Guiot… - The Lancet, 2002 - thelancet.com
Ion-channel gene defects are associated with a range of paroxysmal disorders, including

[HTML][HTML] Single-cell RNA-seq reveals that glioblastoma recapitulates a normal neurodevelopmental hierarchy

…, C Lee, YCD Wang, V Wee Yong, MC Guiot… - Nature …, 2020 - nature.com
Cancer stem cells are critical for cancer initiation, development, and treatment resistance.
Our understanding of these processes, and how they relate to glioblastoma heterogeneity, is …

[HTML][HTML] Monoamine oxidase B inhibitor, selegiline, reduces 18F-THK5351 uptake in the human brain

…, J Therriault, MS Kang, M Shin, MC Guiot… - Alzheimer's research & …, 2017 - Springer
Background 18 F-THK5351 is a quinoline-derived tau imaging agent with high affinity to paired
helical filaments (PHF). However, high levels of 18 F-THK5351 retention in brain regions …

[HTML][HTML] Spatially distinct tumor immune microenvironments stratify triple-negative breast cancers

…, R Salgado, MC Guiot… - The Journal of …, 2019 - Am Soc Clin Investig
Understanding the tumor immune microenvironment (TIME) promises to be key for optimal
cancer therapy, especially in triple-negative breast cancer (TNBC). Integrating spatial …
