Intra-cisterna-magna bevacizumab injection (ICM-BI) reproduces pathological alterations of cerebral small vessel diseases.

ABSTRACT: General modeling strategies for sporadic cerebral small blood vessel diseases (CSVDs) include limiting blood stream in large blood vessels and inducing systemic hypertension, in which small blood vessel deficit is either a secondary or concomitant pathology. In the current study, we introduce that intra-cisterna-magna Bevacizumab injection (ICM-BI) directly causes cerebral small blood vessel injury by neutralizing VEGF-A, the indispensable growth factor for angiogenesis. ICM-BI reproduces neuro-functional impairment, tight junction loss, cerebral micro-bleeds (CMBs), amyloid peptide accumulation, neuronal injury, white matter loss, and glial cell activation, which are common manifestations of sporadic CSVDs. Compared with existing CSVD models, small blood vessel injury is more prominent in
