Alzheimer's disease (AD) is a progressive degenerative disorder that affects more than 35 millions of people throughout the world and still has no therapy able to stop its course or even prevent its instauration. Abnormal neurogenesis and neuroinflammation are processes inherent to pathogenesis of AD, and therefore signs that promote these processes can act as initial deleterious triggers. In this context, recent data show that the kinin system is stimulated by the pathologic ²-amyloid (²A) in AD patients. The effects of this system are primarily mediated by bradykinin (BK) and its kinin-B2 receptor (B2R), and comprehend the direct action on neural stem cells inducing neurogenesis, growth of neurites, permeabilization of the blood-brain barrier, synthesis of IL12 (that results in polarization of lymphocytes to the Th1 cytokine profile) and the strong mediation of inflammation that for its turn can also affect neurogenesis. However, the role of BK/B2R in the processes inherent to AD pathogenesis (neurogenesis and inflammation) and its progression is unknown. This project proposes to elucidate this role by using transgenic double mice as model of the familial AD, both expressing or not expressing B2R (APPswe/PSldE9+/-B2R-/- and APPswe/PSldE9+/-B2R-/-). For identification of possible downstream mechanisms of BK mediated by inflammation and cellular immune response APPswe/PSldE9 mice treated with minocycline and knockout animals for IL-12, respectively, will also be used. Half of these animals will be treated with a stable agonist of the B2R (lysyl-BK). These study groups will be evaluated for neural differentiation, including proliferation and neurogenesis of neural stem cells (NSCs) as well as the dendritic survival and complexity of young neurons in the hippocampus of mice of 2 and 6 months of life. The NSCs of these animals will also be differentiated and treated in vitro to evidence or to exclude any effects on the inflammatory niche. At the same time, patterns of inflammation and cellular immune response in the hippocampus will be determined, such as the levels of the main proinflammatory cytokines, the frequency of activated microglia and T cells. Finally, effects of BK/B2R and subsequent possible mechanisms downstream on AD pathogenesis and progression through the detected concentration of ²A, frequency of ²A platelets and cognitive deficits, will be determined.
