Localization of eosinophil granule major basic protein in human basophils
In experiments using an immunofluorescent method to localize human eosinophil granule major basic protein (MBP) in cells and tissues, a small number of cells stained for MBP that subsequently could not be identified as eosinophils. Because the Charcot-Leyden crystal protein, another eosinophil protein, was recently identified in basophils, we tested whether MBP might also be a constituent of bl...
متن کاملEvidence of eosinophil granule major basic protein in human placenta
A protein immunochemically related to the eosinophil granule major basic protein (gMBP) is found in increased concentration in the plasma of pregnant women and has been localized to placental trophoblasts by immunofluorescence. Pregnancy MBP (pMBP) is indistinguishable from gMBP in its reactivity with polyclonal antisera and a panel of 14 mouse mAbs. We report the purification of pMBP from huma...
متن کاملEosinophil Secretion of Granule-Derived Cytokines
Eosinophils are tissue-dwelling leukocytes, present in the thymus, and gastrointestinal and genitourinary tracts of healthy individuals at baseline, and recruited, often in large numbers, to allergic inflammatory foci and sites of active tissue repair. The biological significance of eosinophils is vast and varied. In health, eosinophils support uterine and mammary gland development, and maintai...
متن کاملActivation of platelets by eosinophil granule proteins
Two of the four principal cationic proteins of the eosinophil granule, major basic protein (MBP) and eosinophil peroxidase (EPO), were shown to be platelet agonists. Both MBP and EPO evoked a dose-dependent nonlytic secretion of platelet 5-hydroxytryptamine in unstirred platelet suspensions even in the presence of 10 microM indomethacin. MBP also evoked secretion of platelet alpha granule and l...
متن کاملEosinophil Granule Major Basic Protein in Basophils
The large specific granule of the human eosinophil contains a number of low molecular weight, highly basic proteins that have been purified to homogeneity, including the major basic protein (MBP) (1-3), 1 the eosinophil cationic protein (4, 5), and the eosinophil-derived neurotoxin (6, 7). The comparative physicochemical and immunochemical characteristics of these proteins have been examined in...
