WebAug 24, 2024 · After adjuvanted subunit immunization, total B cell numbers increase as much as 4-fold within 4 days, in a manner dependent on the adjuvant. The largest increase seen was predictably with a vaccine that utilizes whole ovalbumin protein (OVA) with poly(I:C) and agonistic CD40 antibody (combined-adjuvant), but all single adjuvants … WebThe inner shell of the chestnut (Castanea crenata) contains various polyphenols, which exert beneficial biological effects. Hence, we assessed the anti-inflammatory efficacy of a chestnut inner shell extract (CIE) in ovalbumin (OVA)-induced allergic asthma. We intraperitoneally injected 20 μg of OVA with 2 mg of aluminum hydroxide on days 0 and 14. On test …

WebJan 21, 2024 · This study investigates the role of FGN in promoting immunotherapy efficacy through modulating oxidative stress in regulatory B cells (Bregs). Blood samples were collected from patients with food allergy (FA) and healthy control (HC) subjects. CD19 + CD5 + Bregs were purified from blood samples by flow cytometry cell sorting. WebSpecific B cells also acquired both antigens rapidly in vivo and presented them to CD4(+) T cells. However, only HEL-specific B cells from OVA-HEL ISCOMS-immunised mice could cross-present OVA to naive OVA-specific CD8(+) T cells. Antigen-specific B cells were also activated selectively by OVA-HEL ISCOMS in vitro and importantly, the presence ...
