Lymphoid organs are integral parts of all vertebrate adaptive immune systems. Primary lymphoid tissues exhibit a remarkable functional dichotomy: T cells develop in specialized thymopoietic tissues located in the pharynx, whereas B cells develop in distinct areas of general hematopoietic areas, such as the kidney or bone marrow.

Organogenesis of lymphoid tissues
Nature Reviews Immunology, 2003The development of lymphoid organs depends on the correct expression of several molecules within a defined timeframe during ontogeny. Although this is an extremely complex process, with each secondary lymphoid tissue requiring subtly different signals, a common framework for lymphoid development is beginning to emerge. Drawing on studies of lymph nodes,

The role of the respiratory tract in the defense against potential pathogens has been a subject of interest to microbiologists, virologists and immunologists for many years. The description of the secretory IgA system, common to mucosal surfaces throughout the body, has extended the interests of immunologists in the mechanisms of mucosal resistance (1).

To surveil an organ for pathogens, lymphoid structures need to sample antigens locally. The full set of lymphoid structures involved in surveilling for brain-tropic pathogens has not been defined. Through comprehensive imaging of the mouse meninges, a new study by Fitzpatrick et al. describes dural-associated lymphoid tissue (DALT) and its contribution

Allergy and the Pharyngeal Lymphoid Tissues
Otolaryngologic Clinics of North America, 1987Allergic reactions involving the pharyngeal lymphoid tissues are thought to play a role in several clinical disorders seen commonly in ear, nose, and throat surgical practices. The pathogenesis of the allergic reaction is discussed in relationship to disorders involving the tonsillar tissues, the upper airways and nasopharynx, and the ear.

Expression of DHX32 in lymphoid tissues
Experimental and Molecular Pathology, 2005DHX32 is a novel putative RNA helicase identified based on its downregulation in acute lymphoblastic leukemia. DHX32 gene has 12 exons, alternative usage of exons 1 and 2 results in the expression of two transcripts that differ in their 5' untranslated region (UTR), consistent with the involvement of two different promoters.

Macrophage heterogeneity in lymphoid tissues
Seminars in Immunopathology, 2013Macrophages in lymphoid organs exhibit a wide variety of phenotypes and functions. These cells excel in the removal of apoptotic cells that arise during the generation of immune cells and are thereby essential for the prevention of auto-immune responses.

The fine structure of lymphoid tissue
Experimental and Molecular Pathology, 1964Abstract The fine structure of the lymphoid tissue is described. Six cell types can be identified and described with reasonable accuracy: reticular cells, macrophages, littoral cells, stem cells, lymphocytes, and plasma cells. The reticular cell resembles the fibroblast in having a pale elongated nucleus, branching cytoplasmic processes, a varying ...

Nephrin in human lymphoid tissues
Cellular and Molecular Life Sciences CMLS, 2006When nephrin, the protein product of NPHS1, was cloned, it was proposed to be specific for the kidney glomerular podocytes. Recently, however, new reports have emerged verifying additional nephrin expression sites, particularly the insulin-producing beta cells of the pancreas, as well as the central nervous system. In this study, we demonstrate nephrin

The cells of the lymphoid tissues primarily involved in the generation of specific immune responses are the lymphocytes. As well as the lymphocytes, cells of the monocyte-macrophage series, which are collectively called accessory cells (ACs) are essential for generation of both cellular and humoral (antibody) responses.
