IgA-induced eosinophil degranulation.
The Journal of Immunology, 1989Abstract Eosinophils play an important role as effector cells in allergic, parasitic, and other conditions. The mechanism(s) by which eosinophils mediate their effector functions was studied by incubation of human normodense eosinophils with Sepharose beads coupled to various Ig isotypes as targets.

Degranulation mechanisms in human leukemic basophils
Clinical Immunology and Immunopathology, 1976Abstract The peripheral blood basophils of a patient with chronic myelogenous leukemia, basophilic phase (up to 85% of circulating leukocytes were mature basophils), and substantially elevated levels of urine histamine were studied in the electron microscope in an attempt to relate morphologic changes to possible mechanisms of mediator secretion.

Neutrophil Degranulation Induced by Haemophilus ducreyi
bchm, 2001Haemophilus ducreyi is the causative bacterium of genital ulcers, which are collectively known as chancroid. Little is known about the cytotoxicity of H. ducreyi. The virulent strains are relatively resistant to phagocytosis and apoptosis by neutrophils.

Automated Measurement of Human Basophil Degranulation
Allergy, 1981Basophils disappear after challenge with specific antigen. A human basophil degranulation test has been carried out on a slide using an enriched cell suspension. On each slide, the same volume of cell suspension was deposited in wells with antigen diluted in buffer or with buffer only (control).

Degranulation of discoid platelets.
The American journal of pathology, 1972Platelet degranulation is a characteristic feature of platelet response to aggregating agents, but the mechanism and route by which secretory organelles are transferred to plasma are still uncertain. In the present study, human platelets were incubated with cytochalasin B, an agent which stabilizes discoid shape, and trypsin, which is known to cause ...
