Cell-Based Therapies for Stroke: Promising Solution or Dead End? Mesenchymal Stem Cells and Comorbidities in Preclinical Stroke Research
Conclusion The high prevalence of comorbidities in patients with stroke indicates the need for therapies in preclinical studies that take into account these comorbidities in order to avoid failures in translation to the patient. Preclinical studies are beginning to evaluate the efficacy of MSC treatment in stroke associated with comorbidities, especially hypertension, for ischemic and hemorrhagic stroke. Regarding aging and diabetes, only ischemic stroke studies have been performed. For the moment, few studies have been performed and contradictory results are being reported. These contradictory results may be due to the u...

Macrophage-Specific Expression of IL-37 in Hyperlipidemic Mice Attenuates Atherosclerosis.
This study was undertaken to elucidate the role of macrophage-expressed IL-37 in reducing the production and effects of proinflammatory cytokines, preventing foam cell formation, and reducing the development of atherosclerosis. Expression of human IL-37 was achieved with a macrophage-specific overexpression system, using the CD68 promoter in mouse primary bone marrow-derived macrophages via retroviral transduction. Macrophage IL-37 expression in vitro resulted in decreased mRNA (e.g., IL-1B, IL-6, and IL-12) and secreted protein production (e.g., IL-6, M-CSF, and ICAM-1) of key inflammatory mediators. IL-37 expression also...
