Glioblastoma multiforme (GBM) is notoriously resistant to immunotherapy due to its intricate immunosuppressive tumor microenvironment (TME). Dysregulated cholesterol metabolism is implicated in the TME and promotes tumor progression. Here, it is found that cholesterol levels in GBM tissues are abnormally high, and glioma‐supportive macrophages (GSMs), an essential “cholesterol factory”, demonstrate...
Narrow bandgap cubic formamidine perovskite (α‐FAPbI3) is widely studied for its potential to achieve record‑breaking efficiency. However, its high preparation difficulty caused by lattice instability is criticized. A popular strategy for stabilizing the α‐FAPbI3 lattice is to replace intrinsic FA+ or I− with smaller ions of MA+, Cs+, Rb+, and Br−, whereas this generally leads to broadened optical...
