Østerud, Bjarne, and Eirik Bjørklid. Role of Monocytes in Atherogenesis. Physiol Rev 83: 1069-1112, 2003; 10.1152/physrev.00005.2003.—This review focuses on the role of monocytes in the early phase of atherogenesis, before foam cell formation. An emerging consensus underscores the importance of the cellular inflammatory system in atherogenesis. Initiation of the process apparently hinges on accumulating low-density lipoproteins (LDL) undergoing oxidation and glycation, providing stimuli for the release of monocyte attracting chemokines and for the upregulation of endothelial adhesive molecules. These conditions favor monocyte transmigration to the intima, where chemically modified, aggregated, or proteoglycan- or antibody-complexed LDL may be endocytotically internalized via scavenger receptors present on the emergent macrophage surface. The differentiating monocytes in concert with T lymphocytes exert a modulating effect on lipoproteins. These events propagate a series of reactions entailing generation of lipid peroxides and expression of chemokines, adhesion molecules, cytokines, and growth factors, thereby sustaining an ongoing inflammatory process leading ultimately to lesion formation. New data emerging from studies using transgenic animals, notably mice, have provided novel insights into many of the cellular interactions and signaling mechanisms involving monocytes/macrophages in the atherogenic processes. A number of these studies, focusing on mechanisms for monocyte activation and the roles of adhesive molecules, chemokines, cytokines and growth factors, are addressed in this review.

Scientific achievements of recent decades indicate that neurogenesis and angiogenesis are interrelated processes in the struggle for functional recovery after ischaemic stroke. This literature review presents current data on the neurovascular interactions in ischaemic stroke, and describes the role of signalling molecules and growth factors in the regulation of neurogenesis and angiogenesis, which are crucial for neuronal survival and neuroplasticity. The authors conducted a literature search for abnormal neuroblast migration into the ischaemic penumbra and the role of signalling molecules, molecular targets of angiogenesis, and role of endogenous growth factors and neurochemical markers in post-stroke vascular regulation in acute cerebral ischaemia. Relevant keywords were entered into the PubMed and Google Scholar search engines, as well as Scopus, Web of Science, MedLine, The Cochrane Library, EMBASE, Global Health, CyberLeninka, eLibrary, and other databases. Despite promising results obtained in animal models, and the data from clinical studies, deeper interrelationships between molecular and cellular interactions of neurogenesis and angiogenesis are still not entirely clear. Further study and understanding of complex interactions between neurogenesis and angiogenesis is needed to find targets for exogenous growth factor administration and changes in endogenous molecule expression for treatment of ischaemic brain injury.
