Advancing CAR T Cell Therapy for Brain Tumors: Overcoming Barriers to Efficacy
Gladstone-UCSF Institute of Genomic Immunology Seminar by Christine Brown, PhD (Deputy Director, T Cell Therapeutics Research Laboratories) on developing and refining redirected CAR T cells for malignant brain tumors, including glioblastoma, tumor heterogeneity, immunosuppressive microenvironments, delivery routes, and manufacturing.
Adventures in Spin Labeling: Clinical Perfusion Imaging and the Path to Technical Innovation
Arterial spin labeling (ASL) MRI has become a vital tool in clinical neuroimaging, enabling noninvasive assessment of cerebral perfusion across a range of conditions including stroke, vascular malformations, and brain tumors. With broader clinical adoption, its practical strengths — as well as important limitations — have become increasingly clear.
More than a beast growing in a passive brain: excitation and inhibition drive epilepsy and glioma progression
Gliomas are brain tumors formed by networks of connected tumor cells, nested in and interacting with neuronal networks. Neuronal activities interfere with tumor growth and occurrence of seizures affects glioma prognosis, while the developing tumor triggers seizures in the infiltrated cortex. Oncometabolites produced by tumor cells and neurotransmitters affect both the generation of epileptic activities by neurons and the growth of glioma cells through synaptic-related mechanisms, involving both GABAergic / Chloride pathways and glutamatergic signaling. From a clinical sight, epilepsy occurrence is beneficial to glioma prognosis but growing tumors are epileptogenic, which constitutes a paradox. This lecture will review how inhibitory and excitatory signaling drives glioma growth and how epileptic and oncological processes are interfering, with a special focus on the human brain.
