MICROPAPILLAE A Surface Specialization of Human Leukocytes
The monocyte, the blood-borne representative of the reticulo-endothelial system (1), has several distinguishing functional attributes related to its cell surface which are dependent upon the presence of divalent cations (Ca++ and/or Mg++) . Among these are : phagocytic capacity, glass adhesion, surface binding of complement, and adhesion to other cells such as lymphocytes (rosette formation) or...
متن کاملChemotaxis of Human Leukocytes
Leukotaxis may be defined as the directional migration of leukocytes toward a chemotactic stimulus and is believed to represent the means by which a massive influx of polymorphonuclear leukocytes occurs in an area of inflammation (30). The attraction of polymorphonuclear leukocytes is brought about by a series of effector substances involving complement components (27), bacterial culture filtra...
متن کاملProteases of human leukocytes.
By L. A. MOUNTER AND WASFI ATIYEH T HE EXISTENCE of considerable proteolvtic activities associated with leukocytes has previously been reported, but little characterization of the enzymes has been carried out.13 Experiments with leukocyte preparations using newer enzyme inhibitors are very limited and it seemed probable that improved characterization might result from studies of this type. It w...
متن کاملMorphometry of human leukocytes.
In order to establish quantitative models of leukocyte functions, several morphometric parameters on individual white cells are needed. These include the diameter, volume, and membrane area of the cells and their nuclei in the undeformed state. A stereologic method was used to obtain these quantities from transmission electron microscopy of random sections through human white blood cells (neutr...
متن کاملEffect of chloroquine on morphology of cytoplasmic granules in maturing human leukocytes--an ultrastructural study.
Bone marrow and peripheral blood from patients who had received chloroquine phosphate were studied to determine the effect of this drug on the ultrastructure of cytoplasmic granules in leukocytes. Neutrophils from approximately one-half of the patients who were treated developed abnormal cytoplasmic granules. Vacuolar, lamellar, and particulate components within abnormal, large granules were pr...
