Lactoferrin, an iron-binding glycoprotein found in high concentrations in human milk and other epithelial secretions and in the secondary (specific) granules of neutrophils, is thought to be responsible for primary defence against microbial infection, mainly as a result of lactoferrin sequestration of iron required for microbial growth. Many other functions(More)
Primary monolayer cultures of normal and malignant human mammary epithelial cells were tested for fibronectin by indirect immunofluorescence using antisera specific for fibronectin. This protein was not detectable on either the normal or malignant epithelial cells. Similar results were obtained for normal and malignant mouse mammary epithelial cell(More)
Lactoferrin (Lf), the major iron-binding component of milk, also a major constituent of the specific granules of neutrophils involved in antimicrobial activity and a glycoprotein thought to play a role in regulatory functions in the hematopoietic system as well as other physiologic activities, is shown to occur in three isoforms. One, Lf-alpha, binds iron;(More)
The concanavalin A (Con A) reactivity of malignant and normal human mammary epithelial cells in culture was determined with a hemadsorption assay. Human erythrocytes were treated with various concentrations of Con A, and these indicator Red Blood Cells were incubated with the test cells in situ in culture dishes. The Con A concentration at which(More)
The RFV strain of the Friend virus complex induces an erythroleukemia that spontaneously regresses. The tropism of regressing Friend virus complex (RFV), which is conferred by its helper MuLV component, MuLV-RF, is different from that of the conventional virus strain, CFV. RFV is NB-tropic and CFV is N-tropic. Passage of nonregressing CFV through Fv-1(More)
Mixtures of friend virus (CFV) and the regressing strain of friend virus (RFV) induce leukemia which regresses. The dominance of the regressing phenotype is solely a function of a threshold dose of RFV. The minimum amount of RFV which induced regression of CFV leukemia is below the titer for induction of friend disease, but does correlate ith the titer of(More)

The erythroleukemia induced in susceptible mice by Friend virus (FV) is a progressive, lethal disease. A variant strain of Friend virus (regressing FV) produces a histopathologically identical leukemia except that the disease spontaneously regresses in 50% of leukemic mice. Normal T-cell and macrophage function are required for regression to occur and in(More)
