CD1 and MR1 are major histocompatibility complex (MHC) class I-related proteins that bind and present non-peptide antigens to subsets of T cells with specialized functions. CD1 proteins typically present lipid antigens to CD1-restricted T cells, whereas MR1 presents vitamin B-based ligands and a variety of drugs and drug-like molecules to MR1-restricted T cells. The CD1 family of antigen presenting molecules has been divided into two groups: Group 1 contains CD1a, CD1b and CD1c, and Group 2 contains CD1d. Additionally, CD1e is expressed intracellularly and is involved in the loading of lipid antigens onto Group 1 CD1 proteins. Humans express both Groups 1 and 2 CD1 proteins, whereas mice onl...
The knowledge of Th17 cells and other cell populations which secrete IL-17A, and/or IL-22 has expanded tremendously since the publication of the first edition “Th17 Cells: Role in Inflammation and Autoimmune Disease” in 2008. The present volume has been completely revised with the addition of new chapters on the IL-17 receptor family and signaling, and an in-depth review of IL-22 and innate lymphoid cells. The differentiation of naïve T cells into regulatory T cells and Th17 cells as well as the plasticity of Th17 cells is discussed. The role of IL-22 in cutaneous inflammation including psoriasis has been reviewed. In addition, the volume contains critical updates on autoimmunity, organ transplantation, tumor immunology and genetic mouse models for mechanistic studies. Lastly, the latest clinical progress in neutralizing antibodies to IL-17A, IL-17RA not only confirms the therapeutic promise foreseen in 2008, but also improves our knowledge of the pathogenesis of autoimmune diseases. In summary, this is a timely update and important review of the clinical and experimental aspects of IL-17, IL-22 and their producing cells.
Natural killer T (NKT) cells are a heterogeneous group of T cells that share properties of both T cells and natural killer (NK) cells. Many of these cells recognize the non-polymorphic CD1d molecule, an antigen-presenting molecule that binds self- and foreign lipids and glycolipids. Upon activation, NK T cells are able to produce large quantities of interferon-gamma, IL-4, and granulocyte-macrophage colony-stimulating factor, as well as multiple other cytokines and chemokines (such as IL-2 and TNF-alpha). NKT cells seem to be essential for several aspects of immunity because their dysfunction or deficiency has been shown to lead to the development of autoimmune diseases (such as diabetes or atherosclerosis) and cancers. NKT cells have recently been implicated in the disease progression of human asthma. The clinical potential of NKT cells lies in the rapid release of cytokines (such as IL-2, IFN-gamma, TNF-alpha, and IL-4) that promote or suppress different immune responses.
The year 2010 marks the centennial for the identification of histamine and the first glimpse of its many physiological functions. From these initial findings a rich tapestry of research has uncovered roles for histamine in almost every physiological process with new findings emerging every year. These diverse roles of histamine have made for fertile ground for the discovery of novel therapeutics, and these drugs have been so successful that the term “antihistamine” has entered the common lexicon. This volume is an attempt to give a snapshot in time as to the current understanding of the role of histamine in just one important therapeutic area—inflammation. The first three chapters prov...
No início da pesquisa da família Lara, conversando com pessoas que carregam este apelido, em Carmópolis de Minas e em Piracema, fui montando a “árvore”. Em contato com o senhor Geraldo de Oliveira Pinto, o Zizico e mais tarde com o senhor Antônio Pinto de Góes e Lara, residente em São João del Rei, este começou a pesquisar os inventários e testamentos que constam nos arquivos daquela cidade, norteado por uma lista, por mim enviado. Certa ocasião em que estive em Mariana para pesquisar o processo de ordenação de um padre de minha família, e aproveitando pesquisei também três padres da família Lara, sendo um deles o Padre Francisco Pinto Rodrigues de Góes e Lara, filho le...
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

This book explores the diverse landscapes wherein women struggle for their personal and social identities and lives, between biology and culture, destiny and choice, shared and individual worlds, tradition and modernity. Their “peripheral lives” have “central meaning” (Chaudhary, this volume) in any society – and as such are approached as a primary subject in this book, as the chapters traverse ten different countries on three continents: North America (United States); Latin America (Brazil, Chile, Colombia); Asia (India); and Europe (United Kingdom, Ireland, Portugal, Finland, Estonia). Throughout these different places, women's lives are an interesting stage for observing the int...
