TIGIT expression dictates the immunosuppressive reprogramming of myeloid cells in glioblastoma.

Glioblastoma (GBM) is a deadly brain cancer with near-universal recurrence despite maximal treatment for which new innovations are sorely needed. Immunotherapy has yet to make significant gains in GBM treatment despite revolutionizing other cancer therapies, due in part to GBM-mediated immune suppression. This immune derangement proceeds through several mechanisms, but increasing evidence points to critical roles for tumor-derived extracellular vesicles (EVs) and immunosuppressive myeloid cells as key factors in this process.

Computational mechanistic insight of fungal metabolites for novel acetylcholinesterase inhibitors.
