  • Identification of cross-reactive allergens in cashew- and pistachio-allergic children during oral immunotherapy. Pediatric allergy and immunology : official publication of the European Society of Pediatric Allergy and Immunology He, Z., Dongre, P., Lyu, S., Manohar, M., Chinthrajah, R. S., Galli, S.

    Abstract

    It has been estimated that around 8% of the children in the U.S. suffer from food allergy and of those, 40% are allergic to multiple foods. Among tree nuts, allergies to pistachios are common in those with cashew nut allergy and multiple homologous allergenic components are shared between the two nuts. Three major allergens from cashew (Ana o 1 at 50 kDa, Ana o 2 major band at 33 kDa and minor band at 53 kDa, and Ana o 3 at 10 kDa) and five major allergens from pistachio (Pis v 1 at 7 kDa, Pis v 2 at 32 kDa, Pis v 3 at 50 kDa, Pis v 4 at 23 kDa, and Pis v 5 at 36 kDa) have been identified. Of those, Ana o 1 and Pis v 3, Ana o 2 and Pis v 2, Ana o 2 and Pis v 5, Ana o 3 and Pis v 1 have been recognized as homologues based on their sequence similarity and cross reactivity to IgE from the patients.

  • Rapid Turnover and High Production Rate of Myeloid Cells in Adult Rhesus Macaques with Compensations during Aging JOURNAL OF IMMUNOLOGY He, Z., Allers, C., Sugimoto, C., Ahmed, N., Fujioka, H., Kim, W., Didier, E. S., Kuroda, M. J. 2018; 200 (12): 4059–67

    Abstract

    Neutrophils, basophils, and monocytes are continuously produced in bone marrow via myelopoiesis, circulate in blood, and are eventually removed from circulation to maintain homeostasis. To quantitate the kinetics of myeloid cell movement during homeostasis, we applied 5-bromo-2'-deoxyuridine pulse labeling in healthy rhesus macaques (Macaca mulatta) followed by hematology and flow cytometry analyses. Results were applied to a mathematical model, and the blood circulating half-life and daily production, respectively, of each cell type from macaques aged 5-10 y old were calculated for neutrophils (1.63 ± 0.16 d, 1.42 × 109 cells/l/d), basophils (1.78 ± 0.30 d, 5.89 × 106 cells/l/d), and CD14+CD16- classical monocytes (1.01 ± 0.15 d, 3.09 × 108 cells/l/d). Classical monocytes were released into the blood circulation as early as 1 d after dividing, whereas neutrophils remained in bone marrow 4-5 d before being released. Among granulocytes, neutrophils and basophils exhibited distinct kinetics in bone marrow maturation time and blood circulation. With increasing chronological age, there was a significant decrease in daily production of neutrophils and basophils, but the half-life of these granulocytes remained unchanged between 3 and 19 y of age. In contrast, daily production of classical monocytes remained stable through 19 y of age but exhibited a significant decline in half-life. These results demonstrated relatively short half-lives and continuous replenishment of neutrophils, basophils, and classical monocytes during homeostasis in adult rhesus macaques with compensations observed during increasing chronological age.
