To generate a useful strategy for mucosal immunization, we have developed an approach of lipidating a multiple Ag peptide (MAP) containing part of the V3 loop from HIV-1 gp120IIIB. In this work, we compare two delivery systems, lipidated MAP in PBS and encapsulation in poly(DL-lactide-co-glycolide) microparticles. Subcutaneous immunization, followed by intragastric administration of MAP peptide...
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 CpGODN encapsulated within PLGA nanosp...
Oestrus ovis L. (Diptera: Oestridae) is a cosmopolitan agent of myiasis in sheep and goats. The parasitic phase begins after adult females deposit first-stage larvae (L1) into the nostrils of hosts; these larvae develop into L2 and L3 in the nasal and sinus horn cavities. Sneezing and nasal discharges are the major clinical signs in infected animals. The pathogenesis of O. ovis infection is cau...
It is well established that cholera toxin (CT) produced by Vibrio cholerae acts as a potent mucosal adjuvant; however, the native form of this molecule causes severe diarrhea. Furthermore, both native CT and its B-subunit derivative bind to monosialogangliosides (GM1) in membrane raft micro-domains on neural tissues and are thus unsuitable for use in humans. In this study, we evaluated the adju...
An intranasal vaccine composed of native outer membrane vesicles (NOMV) not exposed to detergent or denaturing agents was prepared from the group B meningococcal strain 9162 SynX(-)(-:15:P1.3:P5.10,11:L3,7,9) and tested in 32 healthy adult volunteers. Four groups of 8 volunteers were vaccinated intranasally with three doses of vaccine. The vaccine was very well tolerated in all dosing groups, d...
Annual outbreaks of seasonal influenza are controlled or prevented through vaccination in many countries. The seasonal vaccines used are either inactivated, currently administered parenterally, or live-attenuated given intranasally. In this study three mucosal adjuvants were examined for the influence on the humoral (mucosal and systemic) and cellular influenza A-specific immune responses induc...
Intranasal vaccination is particularly a striking route for mucosal immunization, due to the ease of administration and the induction of both mucosal and humoral immunity. However, soluble antigens (Ag) are not sufficiently taken up after the nasal administration and need to be co-administered with adjuvants, penetration enhancers or encapsulated in particles. So, in this study, tetanus toxoid ...
