Feruloyl oligosaccharide 1 (FO1) and feruloyl oligosaccharide 2 (FO2) were produced from wheat bran fermented by Aureobasidium pullulans (A. pullulans) through oneand two-stage temperature and pH controlling processes, respectively. Here the anti-tumor and immunostimulatory functions of FO1 and FO2 were further examined. Both FO1 and FO2 inhibited the growth of cancer cells but were non-toxic t...
Immunotherapy (IT) by injection more readily induces clinical tolerance to stinging insects than to respiratory allergens. However, while systemic immunization induces adaptive responses systemically, the induction of mucosal immunity generally requires local Ag exposure. Taken together, these observations suggest that the poor success rate of systemic IT for asthma could be a consequence of in...
Poke weed mitogen (PWM), a lectin purified from Phytolacca americana is frequently used as a B cell-specific stimulus to trigger proliferation and immunoglobulin secretion. In the present study we investigated the mechanisms underlying the B cell stimulatory capacity of PWM. Strikingly, we observed that highly purified PWM preparations failed to induce B cell proliferation. By contrast, commerc...
Archaeosomes are liposomal vesicles composed of ether glycerolipids unique to the domain of Archaea. Unlike conventional ester-linked liposomes, archaeosomes exhibit high stability and possess strong adjuvant and immunostimulatory properties making them an attractive vaccine delivery vehicle. Traditionally comprised of total polar lipids (TPL) or semi-synthetic phospho-glycerolipids of ether-li...
The growth factor GM-CSF has an important role in pulmonary surfactant metabolism and the regulation of antibacterial activities of lung sentinel cells. However, the potential of intra-alveolar GM-CSF to augment lung protective immunity against inhaled bacterial pathogens has not been defined in preclinical infection models. We hypothesized that transient overexpression of GM-CSF in the lungs o...
A safe and effective Hantaan virus (HTNV) vaccine is highly desirable because HTNV causes an acute and often fatal disease (hemorrhagic fever with renal syndrome, HFRS). Since the immunity of the inactivated vaccine is weak and the safety is poor, HTNV virus-like particles (VLPs) offer an attractive and safe alternative. These particles lack the viral genome but are perceived by the immune syst...
Synthetic unmethylated cytosine-guanine (CpG) oligodeoxynucleotides are immunostimulatory motifs that have shown promise as vaccines or adjuvants for diseases such as cancers and infectious diseases. In the present work, novel immuno-nanoflowers (NFs), self-assembled from long DNA integrated with tandem CpG through rolling circle replication, were developed for efficient CpG delivery and protec...
