Cytokines and chemokines are likely to be involved in the pathogenesis of inflammatory diseases of the canine respiratory tract. The roles and relative amounts of these molecules have not yet been defined in the respiratory mucosa of normal dogs or dogs with naturally acquired respiratory inflammation. In the present study, real-time reverse transcriptase polymerase chain reaction (RT-PCR) assays were employed to quantify messenger RNA (mRNA) encoding the chemokines monocyte chernotactic protein (MCP)-2, eotaxin-2 and eotaxin-3, and the cytokines interleukin-4 (IL-4), IL-5, IL-6, IL-10, IL-12p40, IL-18, interferon-gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta (TGF-beta) in normal nasal, bronchial and pulmonary tissues from puppies (n = 4) and from adult dogs (n = 7). There was no significant difference in the expression of any transcript between puppies and adult dogs at any of the anatomical sites examined. The expression of mRNA encoding eotaxin-2 and eotaxin-3 increased significantly with progression from the nasal mucosa to pulmonary parenchyma but expression of MCP-2 mRNA did not show this trend. At all levels of the respiratory mucosa, the most abundant transcripts were those encoding IL-18 and TGF-beta. Transcripts encoding IL-6, IL-10, IL-12 and TNF-alpha were approximately ten-fold less abundant, and IL-4, IL-5 and IFN-gamma were the least abundant templates. There was significantly different amount of mRNA encoding IL-5, IL- 18 and TNF-alpha between particular anatomical levels of the respiratory mucosa while the mRNA expression of the other cytokines was similar at all anatomical sites. The results of the present study will enable comparisons to be made with results obtained from similar samples obtained from dogs with nasal, bronchial or pulmonary diseases. (c) 2004 Elsevier B.V.

Histochemistry and immunohistochemistry were used to characterize leucocyte subsets in the respiratory tract of 15 outbred dogs (five aged <6 months and 10 aged >1 year) that had no evidence of respiratory disease. No organized nose- or bronchus-associated lymphoid tissue was observed in any of the sections examined. IgA(+) plasma cells predominated in nasal mucosa and in all parts of the bronchial tree, with fewer IgG(+) and IgM(+) plasma cells. The numbers of IgA(+) and IgM(+) cells were significantly greater in the nasal mucosa than in any other part of the respiratory mucosa. There were significantly fewer IgA(+), IgG(+) and IgM(+) cells in all parts of the respiratory tract in the puppies than in the adults. The number and distribution of mast cells and cells expressing MHC class II, L1 or CD1c were recorded. Mast cells were mainly found in the subepithelial lamina propria of nasal and bronchial mucosa and in the alveolar interstitium, and cells expressing IgE had a similar distribution. Mast cells were also present within muscle layers of the bronchial tree. The numbers of mast cells and MHC class II(+) cells were significantly greater in the nasal mucosa than in any other part of the respiratory mucosa. In the nose, carina and primary and secondary bronchus, there were significantly more mast cells and MHC class II(+) cells in puppies than in adult dogs, whereas the numbers of L1(+) cells and CD1c(+) cells in most sites were significantly greater in older dogs. There were significantly more CD3(+) and CD8(+) cells in the nasal mucosa than in any part of the bronchial mucosa. In most parts of the respiratory mucosa, CD4(+), CD8(+) and TCR alphabeta(+) cells were present in significantly greater numbers in adults than in puppies. All parts of the respiratory tract had similar numbers of mucosal CD4(+) and CD8(+) T lymphocytes. TCR gammadelta(+) cells were absent or sparse in all samples. These data, obtained from dogs without respiratory disease, will enable comparisons to be made with dogs suffering from infectious or inflammatory nasal, bronchial and pulmonary diseases. [less ▲]

Immunohistochemistry was used to characterize the distribution of leucocyte subsets in the bronchial mucosa of 11 dogs with idiopathic eosinophilic bronchopneumopathy (EBP). Formalin-fixed tissues from all dogs were included in the study, but frozen tissue from only one dog was available. MHC class II(+) cells were found in moderate numbers in the lamina propria (LP). These cells were morphologically either dendritic-like cells or macrophages, but many macrophages did not express MHC class II. Such molecules were expressed by occasional fibroblasts. L1(+) cells, which formed a relatively small component of the LP inflammatory infiltrate, were morphologically either macrophages or polymorphonuclear cells (probably eosinophils). IgA(+) plasma cells were found in varying numbers in the LP, mostly in association with glandular tissue. IgG(+) plasma cells were less common, and IgM(+) plasma cells were present in low numbers. Many CD3(+) cells were present in the LP. In the single case from which frozen tissue was available, most of the lymphocytes were labelled with CD4 marker, while smaller numbers were CD8(+) T cells. Most of the lymphocytes in this case were positively labelled with T-cell receptor (TCR)-alphabeta marker. TCR-gammadelta(+) cells, although less common, were present in significant numbers throughout the LP. CDlc(+) dendritic cells were numerous in the epithelium and in the LP, immediately beneath the basement membrane. These findings, which were similar to those described in human asthma, are suggestive of a Th2 dominant immune response in canine EBP. As in human asthma, this provides a possible basis for new forms of treatment in canine EBP. [less ▲]
