Background And Purpose: Post-stroke cognitive impairment (PSCI) has become a major public health issue, as a leading cause of dementia. The inflammation that develops soon after cerebral artery occlusion and may persist for weeks or months after stroke is a key component of PSCI. Our aim was to take advantage of the immunomodulatory properties of peripheral blood mononuclear cells (PB-MNC) stimulated with ephrin-B2/fc (PB-MNC) for preventing PSCI.

Vascular risks factors such as hypertension and diabetes are involved in most stroke patients, aggravate stroke severity, but are still poorly taken into account in preclinical studies. Microangiopathy and sustained inflammation are exacerbated, likely explaining the severity of stroke in those patients.

Reliable prognostic criteria are needed to distinguish progressive from stable sAVMs and thus support the indication for an aggressive or a conservative management to avoid severe facial disfigurement.
Materials And Methods: We prospectively included 25 patients with untreated facial sAVMs, 15 patients with surgically resected sAVMs and 15 controls.
Clinical trials of cell therapy in stroke favor autologous cell transplantation. To date, feasibility studies have used bone marrow-derived mononuclear cells, but harvesting bone marrow cells is invasive thus complicating bedside treatment. We investigated the therapeutic potential of peripheral blood-derived mononuclear cells (PB-MNC) harvested from diabetic patients and stimulated by ephrin-B2 (PB-MNC+) (500,000 cells), injected intravenously 18-24 hours after induced cerebral ischemia in mice.
