objective(s) the immunoadjuvant potential of cross-linked dextran microspheres (cdm) as absorption enhancer and quillaja saponins (qs) as immunomodulator adjuvant was evaluated. materials and methods cdm loaded or tetanus-mixed toxoid (tt) or quillaja saponin (qs) were nasally administered to rabbits in dry powder form, three times in 2 weeks interval and serum igg and nasal lavage siga titers ...

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 ...

Objective(s) The immunoadjuvant potential of cross-linked dextran microspheres (CDM) as absorption enhancer and Quillaja saponins (QS) as immunomodulator adjuvant was evaluated. Materials and Methods CDM loaded or tetanus-mixed toxoid (TT) or Quillaja saponin (QS) were nasally administered to rabbits in dry powder form, three times in 2 weeks interval and serum IgG and nasal lavage sIgA tite...

Micro- and nanospheres composed of biodegradable polymers show promise as versatile devices for the controlled delivery of biopharmaceuticals. Whereas important properties such as drug release profiles, biocompatibility, and (bio)degradability have been determined for many types of biodegradable particles, information about particle degradation inside phagocytic cells is usually lacking. Here, ...

The properties of nanoparticles, however, are not only dependent on their size and shape, but also are determined by surface modification. As a novel in-depth profile control agent, nanoscale water-soluble cross-linked polyacrylamide microsphere has better compatibility, sealing and oil property. To improve the salt tolerances and shearing resistance, hydrophobic monomer is introduced to invers...
