The antigenic and functional properties of splenic sinusoidal lining cells (SLC) have not been studied extensively. Some investigators have suggested that SLC are actively phagocytic, and thus part of the mononuclear phagocyte system. Others dispute this and assign the functions of endothelial cells to the SLC. During studies in situ of phenotypic(More)
Macrophages (M phi s) are an important component of the immune response and mediate numerous other functions. Phenotypic and functional subsets of circulating monocytes have been described, but few similar studies have analyzed M phi s in human tissues. By use of immunohistochemical techniques and a large number of monoclonal antibodies, the presence and(More)
Certain tissues, such as the spleen, are rich sources of mononuclear phagocytes (MP); however, separating the phagocytes from tissues and removing the contaminating cells have been difficult. We report here a method for the extraction and purification of human splenic MP that employs gentle homogenization of splenic fragments with a Tenbroeck tissue(More)
Most of the monoclonal antibodies (MoAbs) to T-lymphocyte subsets are, with few exceptions thought to recognize antigens (Ags) unique to T-cells. The authors examined the distribution of cells reacting with MoAbs to the helper/inducer (OKT4, anti-Leu-3a,b) and suppressor/cytotoxic (OKT8, anti-Leu-2a) T-lymphocyte subsets and to "pan T" Ags (anti-Leu-1,(More)
