CD33 is a myeloid differentiation antigen with endocytic properties. It is broadly expressed on acute myeloid leukemia (AML) blasts and, possibly, some leukemic stem cells and has therefore been exploited as target for therapeutic antibodies for many years. The improved survival seen in many patients when the antibody-drug conjugate, gemtuzumab ozogamicin, is added to conventional chemotherapy ...
BACKGROUND Infections with some bacteria, including Streptococcus pneumoniae, have been associated with a reduced incidence of asthma. Components of S pneumoniae may have the potential to modulate allergic inflammatory responses and suppress the development of asthma. OBJECTIVES To determine if human S pneumoniae vaccines have the potential to suppress asthma by elucidating their effect on al...
haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. the disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. despite the availability of new and more powerful antibiotics children with hib meningitis still suffer from high mortality or morbidity. the emergence of multir...
A new, simple and sensitive flow cytometric assay for the determination of the cytotoxic activity of human natural killer cells is described. The assay is based on the use of two fluorochromes. The target cell population is stained with one fluorochrome (octadecylamine-fluorescein isothiocyanate, F-18) prior to incubation with the effector cells. F-18 remains in the membrane of the target cells...
The lepromatous leprosy granuloma is a dynamic entity requiring a steady influx of macrophages (Mphi) for its maintenance. We have developed an in vitro model to study the fate of Mycobacterium leprae in a LL lesion, with and without immunotherapeutic intervention. Target cells, consisting of granuloma Mphi harvested from the footpads of M. leprae-infected athymic nu/nu mice, were cocultured wi...
Using the redox-active DNA conjugate (ferrocene-modified oligonucleotide 12 mer) as a probe, the novel electrochemical gene sensor, which is sensitive, convenient, and not relying on radio isotope, has been developed. Oligonucleotide (16 mer) complementary to the target (19 mer) was immobilized onto gold electrode through the specific chemisorption of successive phosphorothioates which were int...
Antibody-drug conjugates utilize the antibody as a delivery vehicle for highly potent cytotoxic molecules with specificity for tumor-associated antigens for cancer therapy. Critical parameters that govern successful antibody-drug conjugate development for clinical use include the selection of the tumor target antigen, the antibody against the target, the cytotoxic molecule, the linker bridging ...
