Endothelium Expression of Bcl-2 Is Essential for Normal and Pathological Ocular Vascularization.

open access: yesPLoS ONE, 2015
Bcl-2 is an anti-apoptotic protein with important roles in vascular homeostasis and angiogenesis. Mice globally lacking Bcl-2 (Bcl-2 -/-) are small in stature and succumb to renal failure shortly after weaning as a result of renal hypoplasia/cystic ...

Involvement of bradykinin B2 receptor in pathological vascularization in oxygen-induced retinopathy in mice and rabbit cornea [PDF]

open access: yes, 2018
The identification of components of the kallikrein-kinin system in the vitreous from patients with microvascular retinal diseases suggests that bradykinin (BK) signaling may contribute to pathogenesis of retinal vascular complications. BK receptor 2 (B2R)

Optimization of the Nonclinical Biological Evaluation of Medical Devices Using Toxicologic Pathology Best Practices

open access: yesAdvanced Healthcare Materials, EarlyView.
Nonclinical evaluation of biological responses to implanted medical devices and combination products in animals is required to predict possible outcomes and risks in patients. This paper describes globally accepted pathology “best practices” that 1) effectively address ISO standards and current regulatory guidance for medical device development and 2 ...
