A study identified a novel APOE4-specific receptor LilrB3. A butterfly-like Cryo-EM structure of the complex reveals the details of how the immune “checkpoint” receptor LilrB3 recognizes APOE4. Upon binding, it will induce microglia cell into an Alzheimer Disease-associated status. See page 116–130 by Jiayao Zhou et al. for details.
