FAS and ischemic stroke: Exclusive localization of Fas‐antibody conjugated NPs at the ischemic region would suggest NP surface attachment in the ischemic region was the contributing factor.[231] The Fas‐PLNPs were loaded with 3‐n‐butylphthalide (a neuroprotective agent in ischemic stroke), and administered i.v. to t‐MCAO mice, which improved clinical scores (reduced infarct area and neurological deficits) compared to administration of the drug alone.[231]Table 3 presents part of recent work on the treatment of ischemic stroke by NPs.
