Lymphoid tissues of “Lethargic” mice
Developmental & Comparative Immunology, 1978Abstract Cellular proliferation in lymphoid tissues of “lethargic” mutant mice and their phenotypically normal littermates was studied by autoradiography with 3 H-thymidine at 23 days of age. Both “lethargic” mutants and normal mice were divided into two groups, one of which received sheep red blood cells (SRC) 7 days prior to sacrifice.

Nasal lymphoid tissue in the rat
Cell And Tissue Research, 1989The structure and organization of paired lymphoid tissue in the nasal mucosa, situated in the transitional zone on both sides of the septal opening of the pharyngeal duct, of conventionally-housed rats was examined by light microscopy and scanning and transmission electron microscopy.

The role of nasopharyngeal lymphoid tissue
Immunology Today, 1992Nasal-associated lymphoid tissue (NALT), which comprises paired lymphoid organs in the nasopharynx of rodents, is the principal mucosal lymphoid tissue of the respiratory tract. As described in this review, NALT bears certain similarities to the Peyer's patches of the intestine but the two differ remarkably in morphology, lymphoid migration patterns ...

Organization of the Invading Lymphoid Tissue in Human Lymphoid Thyroiditis
Scandinavian Journal of Immunology, 1974The structural pattern of lymphoid tissue in lymphoid thyroiditis was analyzed by thin‐section histology in ten thyroidectomy specimens representing focal and massive thyroiditis. Special attention was devoted to the identification of high‐endo‐thelium postcapillary venules, which were found in eight cases, they were absent only in two of the ‘focal ...

T cell immunity in lymphoid and non-lymphoid tissues
Current Opinion in Immunology, 2002Immune responses to infection or effective vaccination generally result in the development of memory lymphocytes capable of mounting a rapid response to secondary infection. Since most infections initiate in non-lymphoid tissues, defense at these sites may be important for protection.

The Efficiency of Entry of Lymphoid Cells into Lymphoid and Non-Lymphoid Tissues
1982Although there are many sites throughout the body where lymphocytes can leave the blood, migrating lymphoid cells appear to discriminate between different tissue destinations. Recirculating lymphocytes normally migrate through the lymph nodes, the spleen and the lymphoid tissues of the gut in preference to non-lymphoid tissues, but lymphoblasts are ...

Bronchus-Associated Lymphoid Tissue
International Archives of Allergy and Applied Immunology, 1982It is well known and appreciated that the lungs contain organized lymphoid tissue. A few years ago while investigating the effect of the introduction of immune complexes into rabbit lungs, we observed that there were present in the bronchial walls lymphoid aggregates which resembled those in the intestine.l–3 Because the Peyer’s patches had been ...

Organization of Mucosal Lymphoid Tissue
1999Mucous membranes form interfaces between internal microenvironments that are subject to homeostatic regulation and external environments that vary widely and are frequently contaminated with microbes and other potentially injurious agents. To offset their inherent vulnerability, mucosal surfaces have therefore been endowed with specialized defense ...
