Neurogenic effects of β-amyloid in the choroid plexus epithelial cells in Alzheimer's disease

, 2013
β-amyloid (Aβ) can promote neurogenesis, both in vitro and in vivo, by inducing neural progenitor cells to differentiate into neurons. The choroid plexus in Alzheimer's disease (AD) is burdened with amyloid deposits and hosts neuronal progenitor cells ...

Macrophage: Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 8, August 2026.
Macrophages are sentinel innate immune cells that arise from embryonic precursors and bone marrow monocytes, displaying a functional continuum that transcends the classical M1 (pro‐inflammatory)/M2 (anti‐inflammatory) dichotomy. Under homeostatic conditions, balanced M1/M2 polarization preserves tissue integrity by coordinating immune surveillance ...

Mechanisms of Therapeutic Resistance and Recent Advances in Glioblastoma Treatment

Immunology &Cell Biology, Volume 104, Issue 7, Page 711-728, August 2026.
Three interconnected processes in glioblastoma (GBM) biology: initiation, stratification, and immunosuppression. 1) Initiation: GBM initiation is proposed to occur through migration of TERT mutation‐bearing neural stem cells from the subventricular zone to the frontal and temporal cortices, where a subsequent oncogenic transformation drives their ...
