Apoptosis is a form of cell death that occurs in a controlled manner and is generally noninflammatory in nature. Apoptosis, or programmed cell death, implies a cell death that is part of a normal physiological process of pruning of unneeded cells. However, many disease conditions utilize apoptosis for pathological ends, resulting in inappropriate cell death and tissue destruction. This book starts with an introduction that reviews the general characteristics of apoptosis, its regulation and its role in physiology and disease. Next, the book focuses on three areas as they relate to inflammatory cells and diseases. The first area consists of chapters on signals for apoptosis important to inflammatory cells, namely growth factors and arachidonic acid metabolism. The next area that the book focuses on are effects at the cellular level, on cell survival versus cell death and signals critical for cell function in both normal and disease states. These topics are covered in chapters on lymphocytes, granulocytes, chondrocytes and keratinocytes. The last area that the book focuses on are events at the level of tissue and disease, looking at the evidence for altered apoptosis and/or apoptotic processes in immune and inflammatory diseases. These topics are covered in chapters on rheumatoid arthritis, osteoarthritis, lupus, psoriasis and renal disease. Together, these chapters will provide the reader with the latest insight in the role of apoptosis in inflammatory cells and diseases.

Clearance of apoptotic cells is essential for proper development, homeostasis and termination of immune responses in multicellular organisms. Thus, cellular and molecular players taking part in the sequential events of this process are of great interest. Research in the last 20 years has indicated that specific ligands and receptors take part in the attraction of immune cells toward apoptotic targets and in the interactions between apoptotic cells and professional as well as non-professional phagocytes that engulf them. Moreover, phagocytosis of apoptotic cells (efferocytosis) leads to significant phenotypic changes in the engulfing cells suggesting that it is a major fate-determining event for phagocytes. Particularly, efferocytosis has an important impact on the inflammation-resolution axis as well as embryonic development and tissue morphogenesis. Deficiencies in these processes can result in health threats, such as autoimmunity, atherosclerosis, bone loss, obesity, infertility, neurodegeneration, fibrosis and cancer. This eBook brings together 24 original research and review manuscripts that cover various aspects of apoptotic cell removal during normal development and homeostasis as well as in tumorigenesis and regenerative processes following injury.

Programmed cell death (PCD) is central in maintaining the life of multicellular organisms, during development as well as in healthy adulthood or in the context of disease. The best understood form of PCD is apoptosis, a caspase mediated, immunologically silent cell death that can be initiated in probably all cell types upon aging, lack of growth support, critical damage or infection. One of the key pathways of apoptosis involves mitochondrial outer membrane permeabilization (MOMP), a process tightly regulated by members of the BCL-2 family. Whereas PCD and apoptosis were used synonymously in the past, other forms of PCD have been discovered more recently, including RIPK1/3- and MLKL-dependent necroptosis, resulting in a necrotic phenotype, and pyroptosis. Interestingly, key components of the necroptotic pathway are actively suppressed by apoptotic caspases, and this interconnection allows a switch in cell death modalities with greatly impact on the host’s immune response. Recent findings link mitochondria and/or MOMP to non-apoptotic forms of PCD, including ferroptosis and necroptosis, putting this organelle even more in the center of cellular death. This article collection highlights the exciting potential and as yet undiscovered regulation of programmed cell death that can impact the immune system and its response.

Nano- and microparticles including crystals, synthetic biomaterials, misfolded proteins or environmental particulates are involved in a wide range of biological processes and diseases. They may present as intrinsic or environmental toxins but may also be applied intentionally, e.g. as immune adjuvants, drug carriers or ion exchangers. The discovery that a wide range of nano- and microparticles share the capacity to induce IL-1β secretion via activation of the NLRP3 inflammasome in dendritic cells and macrophages has led to the hypothesis that nano- and microparticles may contribute in a uniform mechanistic manner to different disease entities. Other molecular mechanisms triggered by a range nano- and microparticles have also recently been identified including (i) the induction of regulated necrosis; (ii) neutrophil extracellular trap (NET) formation and (iii) foreign body granuloma formation as a mechanism of persistent tissue inflammation and scarring. Research on the biology of nano- and microparticle handling is currently under intense investigation. The cell type-specific responses of nano- and microparticle exposure deserves careful attention as well as the related secondary responses to these particles that lead to tissue remodeling. The immune system is at the center of these processes in terms of particle clearance, particle-induced cell death and inflammation, thereby limiting particle-related inflammation and orchestrating wound healing responses. In this Research Topic, we welcomed the submission of Original Research, Review and Mini-Review articles that addressed the significance of the immune system in particle-induced cell death, inflammation and immune responses. These findings will help facilitate new approaches to the prevention and management of particle-related diseases.

In multicellular organisms, states with a high degree of tissue turnover like embryogenesis, development, and adult tissue homeostasis need an instantaneous, tightly regulated and immunologically silent clearance of these dying cells to ensure appropriate development of the embryo and adult tissue remodelling. The proper and swift clearance of apoptotic cells is essential to prevent cellular leakage of damage associated molecular patterns (DAMPs) which would lead to the stimulation of inflammatory cytokine responses. In addition to the clearance of apoptotic cells (efferocytosis), backup mechanisms are required to cope with DAMPs (HMGB-1, DNA, RNA, S100 molecules, ATP and adenosine) and other intracellular material (uric acid, intracellular proteins and their aggregates) released from cells, that were not properly cleared and have entered the stage of secondary necrosis. Furthermore, under certain pathologic conditions (e.g. gout, cancer, diabetes) non-apoptotic cell death may transiently occur (NETosis, necroptosis, pyroptosis) which generates material that also has to be cleared to avoid overloading tissues with non-functional cellular waste. Efficient efferocytosis is therefore indispensable for normal tissue turnover and homeostasis. The characterization of various signalling pathways that regulate this complex and evolutionary conserved process has shed light on new pathogenetic mechanisms of many diseases. Impaired clearance promotes initiation of autoimmunity as well as the perpetuation of chronic inflammation, but may also foster anti-tumor immunity under certain microenvironmental conditions. Immunological tolerance is continuously being challenged by the presence of post-apoptotic remnants in peripheral lymphoid tissues. Besides the autoimmune phenotype of chronic inflammatory rheumatoid disorders a plethora of pathologies have been associated with defects in genes involved in clearance, e.g. atherosclerosis, cancer, gout, diabetes, some forms of blindness, neuropathy, schizophrenia and Alzheimer’s disease. The main goal of this research topic is to collect contributions from various disciplines committed to studying pathogenetic mechanisms of the aforementioned disorders and dealing with alterations in the clearance of dying and dead cells, their remnants, and their constituents that leak out after membrane rupture. Integrating the combined collection of knowledge on efferocytosis and clearance of dead cells and their derived waste from different fields of research in physiology and pathophysiology could improve the molecular understanding of these increasingly prevalent diseases and may ultimately result in new therapeutic strategies.

Starting with discussion of basic concepts and the molecular mechanisms of necrosis, this book looks first at several forms of necrotic cell death that have been identified, including necroptosis, autophagic cell death, and PARP-mediated cell death. As necrotic cell death is increasingly known to play a critical role in many physiological processes, the next chapters discuss its effect on metabolism, inflammation, immunity, and development. Necrotic cell death is closely implicated in human diseases like cancer, so the next chapters examine its relevance to human diseases, and final chapters cover methodologies for measuring necrosis. This book presents comprehensive coverage of necrosis from recognized experts from leading academic and medical institutions around the world. ​In contrast to apoptosis, well-defined as a form of programmed cell death, necrosis used to be considered as accidental (i.e., non-programmed) cell death, usually in response to a severe injury. Accumulating evidence now suggests, however, that necrosis is also programmed and controlled by distinctive "death machinery" in response to various stimuli like oxidative stress or DNA damage.
