Conclusions:  These data show that under some inflammatory conditions,

Gpx1 regulates leukocyte-endothelial cell interactions in the cerebral microvasculature, but that this is affected by the nature of the inflammatory insult. “

Microcirculation 18(7), 598–607. Objective:  Angiogenesis, a critical contributor to ocular as well as neoplastic diseases, is stimulated by endothelial production of angiopoietin-2 (Ang2). Our objective was to determine the requirement of ocular angiogenesis for Ang2 in animal models of disease. Methods:  Cobimetinib We developed and compared the effect of a novel human Ang2 antibody with a pan-angiopoietin strategy on angiogenesis in ocular angiogenesis in animal models of oxygen-induced retinopathy,

and laser photocoagulation and confirmed its efficacy in xenografted human colorectal tumors. Results:  Human anti-Ang2 and anti-angiopoietin1(Ang1)/Ang2 antibodies blocked colorectal carcinoma growth in immuno-compromised mice (p < 0.001, n = 6). Injection of 1 μg of Ang2 or Ang2/Ang1 antibody-inhibited angiogenesis in models of retinal (p < 0.001, n = 6), and choroidal neovascularization (p < 0.001, n = 11–13 per group) to levels similar to that with anti-VEGF antibodies. There was no difference between Ang2 specific and Ang1/Ang2 bi-specific antibodies. In vitro, Ang2 antibodies showed

no cytotoxicity and did not inhibit endothelial cell migration or proliferation. Conclusion:  Thus, human Ang2 antibodies are potentially therapeutic agents for ocular neovascularization in models of retinal and choroidal neovascularization, in the absence of VEGF inhibition. Tau-protein kinase “
“Microcirculation (2010) 17, 192–205. doi: 10.1111/j.1549-8719.2009.00015.x Hypertension, hypercholesterolemia, diabetes, and obesity are among a growing list of conditions that have been designated as major risk factors for cardiovascular disease (CVD). While CVD risk factors are well known to enhance the development of atherosclerotic lesions in large arteries, there is also evidence that the structure and function of microscopic blood vessels can be profoundly altered by these conditions. The diverse responses of the microvasculature to CVD risk factors include oxidative stress, enhanced leukocyte- and platelet-endothelial cell adhesion, impaired endothelial barrier function, altered capillary proliferation, enhanced thrombosis, and vasomotor dysfunction. Emerging evidence indicates that a low-grade systemic inflammatory response that results from risk factor-induced cell activation and cell-cell interactions may underlie the phenotypic changes induced by risk factor exposure.
