Distribution and function of non-lymphoid cells positive for monoclonal antibody CVI-ChNL-68.2 in healthy chickens and those infected with Marek's disease virus.
Immuno-enzyme histochemistry was used to study the staining pattern and tissue distribution of monoclonal antibody CVI-ChNL-68.2 that specifically reacts with a subset of non-lymphoid cells in healthy chickens and those infected with Marek's disease virus (MDV). Functional characteristics of CVI-ChNL-68.2-positive cells, e.g. antigen uptake, are determined. In the liver CVI-ChNL-68.2 recognizes reticulum cells, whereas in the bursa of Fabricius it detects single cells in the interfollicular connective tissue. In the spleen CVI-ChNL-68.2 reacts selectively with the reticulum cells of the ellipsoid. In some MDV-infected chickens the splenic reticulum cells show a different staining and distribution pattern. Furthermore, the proliferative lesions associated with Marek's disease contain many CVI-ChNL-68.2-positive cells. The possible role of CVI-ChNL-68.2-positive cells in disseminating Marek's disease virus is discussed.
