Osteoimmunology

This is the second edition of this proceedings. Contributors include leading names in the field of research, addressing mutiple topics, which were covered at the last Osteoimmunology conference.

This fully updated and extended second edition provides a comprehensive overview on the basic concepts of the rapidly developing field of osteoimmunology and also offers in-depth insights into the molecular mechanisms of bone diseases. Clinical data is presented and put into context with the latest research findings. This second edition in addition discusses the latest topics in transplantation immunology. The book addresses scientists and physicians working in immunology, pathophysiology and osteology.

Osteoimmunology: Interactions of the Immune and Skeletal Systems, Second Edition, explores the advancements that have been made in the field during the last 40 years, including valuable information on our understanding of the interactions between hematopoietic, immune, and bone cells, now known as the field of osteoimmunology. This comprehensive work offers the most extensive summaries of research trends in the field and their translation into new therapeutics. Early chapters deal with the development of osteoblasts, osteoclasts, hematopoietic stem cells, T and B-lymphocytes, and communications between these cellular elements, while later sections contain discussions of the signaling pathways by which RANKL influences osteoclast development and function. Subsequent chapters explore the effects that estrogen has on bone and the immune system, the development of pathologic conditions, and the growing research around osteoporosis, Paget’s disease, the genetics of bone disease, and bone cancer metastasis. Explains the intricate interaction between the immune system and bone Features detailed discussions of the key cellular and molecular mechanisms governing the homeostasis of the individual systems Facilitates greater understanding of osteoimmunologic networks, their environments, and how this understanding leads to better treatments for human diseases involving both systems

Bone metastases are common in many cancers and associated with skeletal-related events such as spinal cord compression, fractures, pain, disability, and impaired quality of life. Bone metastasis is most prominent in breast, prostate, and lung cancer patients and is the leading cause of cancer-associated death. Osteoblasts and osteoclasts control each other’s functions to maintain normal bone homeostasis. In addition, bone remodeling is governed by the balanced activity of the bone and immune cells. Bone metastasis is a multistage process, and the bone microenvironment influences the seeding and colonization of the disseminated cancer cells. Disruption of bone homeostasis and immune population provides fertile soil to facilitate cancer cell seeding. Despite the advancement of our understanding to treat primary tumors, most of the treatments for bone metastasis are palliative. Proper understanding of the immune component of the bone and their involvement in bone metastasis niche formation will help to explore future directions of bone metastasis research.
