To develop an immunotherapeutic vaccine for treatment of allergic rhinitis, we developed a controlled release formulation of Cryj1, a major Japanese cedar pollen allergen, with immunostimulatory potency. Two sets of hexapod-like structured DNA (hexapodna) were prepared using six oligodeoxynucleotides (ODNs) each, including ODNs with an unmethylated cytosine-phosphate-guanine (CpG) sequence (CpG...
in induction of systemic and mucosal immunity, particulate antigens are more effective than soluble antigens possibly because they are more efficiently endocytosed by mucosal-associated lymphoid tissue (malt) m cells. in this study, we determined the systemic and mucosal immune responses in rabbits following intranasal immunization of tetanus toxoid tt and cpg-odn encapsulated within plga nanos...
Astronauts experience Space Motion Sickness requiring treatment with an anti-motion sickness medication, scopolamine during space missions. Bioavailability after oral administration of scopolamine is low and variable, and absorption form transdermal patch is slow and prolonged. Intranasal administration achieves faster absorption and higher bioavailability of drugs that are subject to extrahepa...
Alzheimer's disease (AD) is the most common type of dementia and has no effective therapies. Previous studies showed that bone morphogenetic protein 9 (BMP9), an important factor in the differentiation and phenotype maintenance of cholinergic neurons, ameliorated the cholinergic defects resulting from amyloid deposition. These findings suggest that BMP9 has potential as a therapeutic agent for ...
Leptin is a hormone that reduces excitability in some hypothalamic neurons via leptin receptor activation of the JAK2 and PI3K intracellular signaling pathways. We hypothesized that leptin receptor activation in other neuronal subtypes would have anticonvulsant activity and that intranasal leptin delivery would be an effective route of administration. We tested leptin's anticonvulsant action in...
Status epilepticus (SE) is a medical emergency characterized by uncontrolled, prolonged seizures with rapid and widespread neuronal damage. Patients that suffer from longer episodes of SE are more likely to have poorer clinical outcomes and a higher cost of healthcare. Understanding novel molecular mechanisms that regulate inhibitory and excitatory neurotransmission that initiate SE and the nec...
The immune-stimulating activities of Bordetella bronchiseptica antigens containing dermonecrotoxin (BBD) loaded in chitosan microspheres (CMs) have already been reported in vitro and in vivo with a mouse alveolar macrophage cell line (RAW264.7) and mice. Therefore, this study attempted to demonstrate the successful induction of mucosal immune responses after the intranasal administration of BBD...
Neonatal hypoxic-ischemic encephalopathy (HIE) is an injury that often leads to detrimental neurological deficits. Currently, there are no established therapies for HIE and it is critical to develop treatments that provide protection after HIE. The objective of this study was to investigate the ability of interferon beta (IFNβ) to provide neuroprotection and reduce apoptosis after HIE. Postnata...
BACKGROUND We previously demonstrated that polyphosphazenes, particularly PCEP, enhance immune responses in mice immunized subcutaneously and intranasally. The objective of the present study was to investigate the efficacy of polyphosphazenes as adjuvants when delivered through different routes of vaccine administration. METHODS BALB/c mice were immunized through intranasal, subcutaneous, ora...
