Abstract
Dendritic cells (DCs) are antigen-presenting cells with a unique ability to induce primary immune responses. DCs capture and transfer information from the outside world to the cells of the adaptive immune system. DCs are not only critical for the induction of primary immune responses, but may also be important for the induction of immunological tolerance, as well as for the regulation of the type of T cell-mediated immune response. Although our understanding of DC biology is still in its infancy, we are now beginning to use DC-based immunotherapy protocols to elicit immunity against cancer and infectious diseases.

WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues

TL;DR: Thank you very much for reading who classification of tumours of haematopoietic and lymphoid tissues, and maybe you have knowledge that, people have look hundreds of times for their chosen readings like this, but end up in malicious downloads.

Alternative activation of macrophages

TL;DR: The evidence in favour of alternative macrophage activation by the TH2-type cytokines interleukin-4 (IL-4) and IL-13 is assessed, and its limits and relevance to a range of immune and inflammatory conditions are defined.

TL;DR: It is suggested that several clinical situations, including autoimmunity and certain infectious diseases, can be influenced by the antigen-specific tolerogenic role of DCs.

Dendritic cells and the control of immunity

TL;DR: Once a neglected cell type, dendritic cells can now be readily obtained in sufficient quantities to allow molecular and cell biological analysis and the realization that these cells are a powerful tool for manipulating the immune system is realized.
Journal ArticleDOI

Efficient presentation of soluble antigen by cultured human dendritic cells is maintained by granulocyte/macrophage colony-stimulating factor plus interleukin 4 and downregulated by tumor necrosis factor alpha.

TL;DR: Cultured DCs are as efficient as antigen-specific B cells in presenting tetanus toxoid (TT) to specific T cell clones and their efficiency of antigen presentation can be further enhanced by specific antibodies via FcR- mediated antigen uptake.

The dendritic cell system and its role in immunogenicity

TL;DR: Dendritic cells are specialized to mediate several physiologic components of immunogenicity such as the acquisition of antigens in tissues, the migration to lymphoid organs, and the identification and activation of antigen-specific T cells.

Tolerance, danger, and the extended family.

TL;DR: The possibility that the immune system does not care about self and non-self, that its primary driving force is the need to detect and protect against danger, and that it does not do the job alone, but receives positive and negative communications from an extended network of other bodily tissues is discussed.

Generation of large numbers of dendritic cells from mouse bone marrow cultures supplemented with granulocyte/macrophage colony-stimulating factor.

TL;DR: The methodology for inducing dendritic cell growth that was recently described for mouse blood now has been modified to MHC class II- negative precursors in marrow, and this feature should prove useful for future molecular and clinical studies of this otherwise trace cell type.
