Abstract
Intraepithelial migrating cells are presumed to play an important role in nasal mucosal immunity because these are the first to come into contact with various foreign particles inhaled and deposited on the nasal surface. To elucidate nasal mucosal immunity, we carried out a quantitative study of the overall population of migrating cells and the lymphocyte subsets in the epithelial compartment of nasal mucosa in patients with house-dust nasal allergy, in patients with nonallergic rhinitis (chronic infectious rhinitis) and “normal” persons (as controls), using both light and electron microscopy in combination with an immunoperoxidase technique. Scrapings from the inferior turbinates were collected for examination of the epithelium. In order of predominance, the most numerous migrating cells were lymphocytes, followed by eosinophils, mast cells, neutrophils, and macrophages in the allergy group; in the nonallergy group neutrophils, lymphocytes, followed by macrophages and eosinophils; and in the normal group lymphocytes were the most predominant. Electron microscopic observation revealed globule leukocytes in addition to the other cells. In subjects with nasal allergy, the migrating cell population in nasal secretion differed from scrapings, in that neutrophils and eosinophils were predominant. In our study of the lymphocyte subsets, although CD8+ cells (suppressor/cytotoxic T cells) were the most numerous (followed by CD16+ [natural killer cells], CD4+ [helper/inducer T cells] and CD21+ [B cells] in that order of predominance in the epithelium), no difference was noted in number among CD4+, CD8+, and CD16+ cells in nasal secretions. On the basis of their ultrafine structure, many CD8+ cells and some CD4+ cells had the morphological appearance of activated lymphocytes. Lymphocytes, mast cells, and globule leukocytes, all of which reside in the allergic nasal epithelium, are likely to be involved in the nasal mucosal immunity.

Granule exocytosis of granulysin and granzyme B as a potential key mechanism in vaccine-induced immunity in cattle against the nematode Ostertagia ostertagi. Infect Immun 2013; 81:1798-809.

Abstract
Ostertagia ostertagi is considered one of the most economically important bovine parasites. As an alternative to anthelmintic treatment, an experimental host-protective vaccine was previously developed on the basis of ASP proteins derived from adult worms. Intramuscular injection of this vaccine, combined with QuilA as an adjuvant, significantly reduced fecal egg counts by 59%. However, the immunological mechanisms triggered by the vaccine are still unclear. Therefore, in this study, the differences in immune responses at the site of infection, i.e., the abomasal mucosa, between ASP-QuilA-vaccinated animals and QuilA-vaccinated control animals were investigated on a transcriptomic level by using a whole-genome bovine microarray combined with histological analysis. Sixty-nine genes were significantly impacted in animals protected by the vaccine, 48 of which were upregulated. A correlation study between the parasitological parameters and gene transcription levels showed that the transcription levels of two of the upregulated genes, those for granulysin (GNLY) and granzyme B (GZMB), were negatively correlated with cumulative fecal egg counts and total worm counts, respectively. Both genes were also positively correlated with each other and with another upregulated gene, that for the IgE receptor subunit (FCER1A). Surprisingly, these three genes were also correlated significantly with CMA1, which encodes a mast cell marker, and with counts of mast cells and cells previously described as globule leukocytes. Furthermore, immunohistochemical data showed that GNLY was present in the granules of globule leukocytes and that it was secreted in mucus. Overall, the results suggest a potential role for granule exocytosis by globule leukocytes, potentially IgE mediated, in vaccine-induced protection against O. ostertagi.

Abstract
A natural infection with Helicobacter pylori (H. pylori) in domestic cats (Felis cattus) less than 2 years of age has been well described in a closed colony of animals. Six cats from this colony that were serially evaluated by culture, polymerase chain reaction, and light and electron microscopy for a period of 3 years demonstrated persistent gastric colonization with a single cag(-) vac(+) strain of H. pylori. In these cats, as well as five other 5- to 6-year-old cats that were examined, a long-term infection resulted in chronic diffuse lymphofollicular atrophic gastritis with areas of mucosal dysplasia in the antrum and predominantly midsuperficial gastritis in the body and cardia. Topographically, the distribution of lesions was similar in both young and older cats and closely resembled that found in humans, with the most severe changes occurring in the gastric antrum. Few granulocytes and no significant elevation in mast cells were seen in older H. pylori-infected cats compared with uninfected controls; however, marked increases in interepithelial globule leukocytes and numerous active mucosal lymphoid follicles were present in infected animals. Indices of gastritis were significantly greater in older infected cats when compared with uninfected controls and younger cats (P < 0.05). The antral cell proliferation index of infected older cats was significantly (P = 0.021) greater than that of uninfected controls. Apoptotic indices of the gastric antrum and body of infected cats were significantly (P = 0.01) increased versus controls. Chronic infection with H. pylori in cats shares many features of long-term H. pylori infection in humans, including the development of preneoplastic processes. This similarity provides useful, comparative insights into host-pathogen interactions.

Abstract
Eosinophilic gastroenterocolitis with peripheral eosinophilia was induced in rats fed a diet containing 2.5% or 5.0% iron lactate for 3 mo. Additional findings consistent with iron overload were also observed. Microscopically, the lesions consisted of eosinophilic infiltrations in the mucosa and submucosa along the whole length of the gastrointestinal tracts, increased surface area of the gastric mucosal propria covered with mucous cells, and increased apoptotic bodies in the gastric glandular neck of rats in the 2.5% and 5.0% groups. An increased number of intraepithelial globule leukocytes in the gastric and intestinal lamina propria was also observed in the 5.0% group. Globule leukocytes in the gastric mucosa contained obviously enlarged granules in their cytoplasm in these rats. The granules of the globule leukocytes were positive for rat mast cell protease II, suggesting the mastocyte origin of these cells. Although severe infiltration of eosinophils and globule leukocytes suggested a type-1 hypersensitivity reaction, other features such as an increasing vascular permeability were not detected. Serum IgE levels in the 5.0% and control groups were < 3 ng/ml. Final body weights of male and female rats of the 5.0% group were suppressed to 70% and 90%, respectively, of those of the control rats, whereas food consumption was comparable to that of the control group. The morphologic characteristics of the gastrointestinal lesions and peripheral eosinophilia induced in rats fed iron lactate were very similar to those in some cases of eosinophilic gastroenterocolitis in humans and other animals.

Abstract
A systemic tumor developed in multiple organs, including spleen, bone marrow, lymph nodes, liver, ovaries, and thoracic and lumbar vertebrae, of a female F344Du/Crj rat. The tumor was composed of round to indented mononuclear cells containing abundant large eosinophilic granules in the cytoplasm. The peripheral blood smear revealed that the large granules in the cytoplasm of the tumor cells were stained basophilic with Giemsa, suggesting a basophil or mast cell origin. However, these granules did not show metachromasia with toluidine blue and were stained blue to dark blue with phosphotungstic acid hematoxylin. Cellular morphology and characteristics in the specific stains of tumor cells suggested the development of a tumor of globule leukocytes in a F344Du/Crj rat.

Abstract
Histochemical characteristics and immunological surface phenotypes of globule leukocytes (GLs) of normal goats were investigated in the intestine. In the small intestine, GLs were concentrated in the base of the villus and around the crypt, whereas in the cecum and colon they were randomly distributed. Their cytoplasmic granules exclusively stained with phosphotungstic acid hematoxylin, and were negative for peroxidase and histamine in contrast to those of subepithelial mast cells. The existence of chondroitin sulfate in some granules of GLs and heparin in most granules of mast cells were revealed by alcian blue staining and digestion with chondroitinase ABC. Isolated intestinal GLs were positive for T cell receptor (TcR) 1-N24 (gamma delta) and CD8 alpha, and negative for WC1-N3 and WC1-N4. Cryostat sections of ileum revealed preferential intraepithelial distribution of both TcR1-N24+ cells and CD8+ cells. WC1-N3+ and WC1-N4+ cells were rarely seen in the epithelium and lamina propria. These results indicate that caprine GLs are a gamma delta T cell subset, which is a different cell population from WC1 positive gamma delta T cells.

Abstract
In a canine model of asthma, the identity and relationships of two types of cells with eosinophilic granules found in bronchoalveolar lavage (BAL) were investigated. Five female and three male newborn mongrel dogs were sensitized by intraperitoneal injection of 500 micrograms ragweed in 30 mg aluminum hydroxide repeated weekly for 8 weeks and then biweekly until 16 weeks of age. Three female and two male littermate controls received 30 mg aluminum hydroxide. From 4 months of age, dogs received six breaths of wet-nebulized ragweed solution through an endotracheal tube bimonthly. Bronchoalveolar lavage was performed 2 months or more after the last exposure to ragweed and was repeated 5 hours after ragweed inhalation. Dogs studied were 15 to 38 months of age. Eosinophilic cell populations were determined in BAL and peripheral blood; cells were examined by light and electron microscopy. Two eosinophilic cell types were in BAL: an eosinophil and an atypical cell with globule leukocyte characteristics. Specific microgranules, a constant feature of eosinophils, were prominent in the atypical cell and suggest a relationship to the eosinophil granulocyte series for the atypical cell and cells identified by others as globule leukocytes. In ragweed sensitized animals, there were more eosinophilic cells in BAL fluid and more eosinophils in peripheral blood. There was a proportional increase in BAL eosinophils 5 hours after ragweed inhalation and a corresponding decline in peripheral blood eosinophils. There was no increase in numbers of eosinophils in the sensitized animals; eosinophil and atypical cell numbers in littermate controls were unchanged.

Abstract
Globule leukocytes, dispersed throughout the respiratory epithelium as single cells, were isolated from rat trachea and were enriched by centrifugation on a discontinuous Percoll gradient. The isolation and enrichment procedure yields a cell fraction containing 75% globule leukocytes. The cell viability, as assessed by trypan blue exclusion, was at least 98%. Cells were maintained in short-term culture without apparent loss of viability and enzyme activity. The isolated globule leukocytes seem not to express significant levels of cytotoxicity against 51Cr-labeled YAC-1 target cells. In fixed cytocentrifuge smears, globule leukocytes appear as more or less rounded to oval cells with a low nucleo-cytoplasmic ratio and with a mostly eccentrically located nucleus. Characteristic intracytoplasmic granules are stained with toluidine blue, alcian blue, and May-Grünwald-Giemsa stains. The applied cytochemical methods demonstrate that tracheal globule leukocytes are stained for alpha naphthyl acetate esterase and naphthol-AS-D-chloroacetate esterase, but not for alpha naphthyl butyrate esterase, N-acetyl-DL-phenylalanine-B-naphthyl esterase, and endogenous peroxidase. Isolated rat peritoneal cells were used as positive control cells for the cytochemical reactions. The obtained cytochemical profile of tracheal globule leukocytes is compared to the known cytochemical profile of intestinal globule leukocytes and large granular lymphocytes. The cytochemical dissimilarities between tracheal and intestinal globule leukocytes may suggest that both kinds of globule leukocytes represent a different form of the same cell type or even different cell types. The cytochemical pattern of tracheal globule leukocytes is closely related to that of large granular lymphocytes, which have been postulated as a possible source for globule leukocytes.(ABSTRACT TRUNCATED AT 250 WORDS)
