Book Description
Inflammation and angiogenesis, the growth of new blood vessels from pre-existing ones, are involved in tumor growth, ocular diseases and wound healing. In ocular angiogenesis, new pathological vessels grow into a specific eye tissue, leak fluid, and disrupt vision. The development of safe and effective therapies for ocular angiogenesis is of great importance for preventing blindness, given that current treatments have limited efficacy or are associated with undesirable side effects. The search for alternative treatment targets requires a deeper understanding of inflammation and how it can lead to angiogenesis in the eye in pathologic situations. This thesis provides new insights into the regulation of inflammation and angiogenesis, particularly at the gene expression and phenotypic levels, in different situations characterized by angiogenesis of the cornea, often called corneal neovascularization. For instance, specific genes and pathways are either endogenously activated or suppressed during active inflammation, wound healing, and during resolution of inflammation and angiogenesis, serving as potential targets to modulate the inflammatory and angiogenic response. In addition, as part of the healing response to restore corneal transparency, inflammation and angiogenesis subside with time in the cornea. In this context, LXR/RXR signaling was found to be activated in a time-dependent manner, to potentially regulate resolution of inflammation and angiogenesis. During regression of new angiogenic capillaries, ghost vessels and empty basement membrane sleeves are formed, which can persist in the cornea for a long time. Here, ghost vessels were found to facilitate subsequent revascularization of the cornea, while empty basement membrane sleeves did not revascularize. The revascularization response observed here was characterised by vasodilation, increased inflammatory cell infiltration and by sprouting at the front of the reperfused vessels. Importantly, reactive oxygen species and nitrous oxide signaling among other pro-inflammatory pathways were activated, and at the same time anti-inflammatory LXR/RXR signaling was inhibited. The interplay between activation and inhibition of these pathways highlights potential mechanisms that regulate corneal revascularization. When treating corneal neovascularization clinically, corticosteroids are in widespread use due to their effectiveness. To minimize the many undesirable side effects associated with corticosteroid use, however, identifying new and more selective agents is of great importance. Here, it was observed that corticosteroids not only suppressed pro-inflammatory chemokines and cytokines, but also activated the classical complement pathway. Classical complement may represent a candidate for further selective therapeutic manipulation to investigate its effect on treatment of corneal neovascularization. In summary, this thesis identifies genes, pathways, and phenotypic responses involved in sprouting and remodeling of corneal capillaries, highlights novel pathways and factors that may regulate inflammation and angiogenesis in the cornea, and provides insights into regulation of capillary regression and reactivation. Further investigation of these regulatory mechanisms may offer alternative and effective treatment targets for the treatment of corneal inflammation and angiogenesis.

Book Description
Ocular angiogenesis, or the abnormal growth of blood vessels in the eye, is the cause of major neovascular eye diseases. With the new era of anti-angiogenic therapies, ophthalmologists have started treating many ocular diseases including macular degeneration, diabetic retinopathy, and retinal vascular occlusion using anti-angiogenic drugs. This book covers the basic pathophysiology of ocular angiogenesis and strategies for inhibition. The authors discuss the "Principles" of anti-angiogenic therapy, pre-clinical studies, future drugs on the horizon, drug delivery, and the "Practice" of the therapy in many ocular diseases. The book also includes chapters on diabetic macular edema, and various therapeutic options for this condition. A companion website includes the fully searchable text and an image bank.

Book Description
This book provides a comprehensive, in-depth review of our current understanding of the growth of blood vessels within the eye. Novel therapeutic strategies for the treatment of ocular angiogenesis are discussed, as are the unique challenges presented by delivery of drugs to the eye. The book emphasizes basic principles rather than specific experimental results, although recently acquired data is frequently cited to illustrate points of broader theoretical significance.

Book Description
This comprehensive reference work, updated from the first edition, brings together the knowledge and expertise of contributors from around the world. It includes new topics such as prostaglandin synthetase enzyme, new synthetic eicosanoids, innovative analytical methods, the influence of cytokines in the regulation of synthesis and actions, newer eicosanoids that influence the cardiovascular system, and newly discovered roles in reproduction and interactions with nitric oxide. This book satisfies a surge of interest in prostaglandins—NSAIDS (e.g. aspirin) are the biggest selling drugs of all time, and the field has been refreshed by the advent of new types (selective COX-2 inhibitors, anti-leukotiene drugs).

Book Description
Angiogenesis has recently played a critical role in regulation of adipose tissue expansion and regression. Like most other tissues in the body, adipose expansion and regression is accompanied by alteration of blood vessel density and structures. The vascular alteration plays an active role in regulation of adipose tissue size and functions. Targeting blood vessels in the adipose tissue have demonstrated to be a novel approach for possibly treatment of cancer, obesity and other metabolic diseases. This book provides the most updated information on this type research and discusses future opportunities for therapy..
