A nebulized gelatin nanoparticle-based CpG formulation is effective in immunotherapy of allergic horses.

Abstract: In the recent years, nanotechnology has boosted the development of potential drug delivery systems and material engineering on nanoscale basis in order to increase drug specificity and reduce side effects. A potential delivery system for immunostimulating agents such as cytosine-phosphate-guanine-oligodeoxynucleotides (CpG-ODN) needs to be developed to maximize the efficacy of immunotherapy against hypersensitivity. In this study, an aerosol formulation of biodegradable, biocompatible and nontoxic gelatin nanoparticle-bound CpG-ODN 2216 was used to treat equine recurrent airway obstruction in a clinical study. Methods: Bronchoalveolar lavage fluid was obtained from healthy and allergic horses to quantify Th1/Th2 cytokine levels before and after inhalation regimen. Full clinical examinations were performed to evaluate the therapeutic potential of this nebulized gelatin nanoparticle-based CpG formulation. Results: Most remarkable was that regulatory anti-inflammatory and anti-allergic cytokine IL-10 expression was significantly triggered by five consecutive inhalations. Thorough assessment of clinical parameters following nanoparticle treatment indicated a partial remission of the allergic condition. Conclusions: Thus this study, for the first time, showed effectiveness of colloidal nanocarrier-mediated immunotherapy in food-producing animals with potential future applicability to other species including humans.

The study describes how nanotechnology is used to formulate a sprayable immunotherapy medication for horses suffering from recurrent airway obstruction. It shows that this treatment methodology is effective in managing allergy symptoms in the tested animals.

Introduction and Study Background

  • The researchers centered their study around nanotechnology, an innovative field that’s expediting the development of new drug delivery systems intended to enhance drug precision and lessen side effects.
  • The focus was to establish an optimum delivery system for immunostimulating agents such as cytosine-phosphate-guanine-oligodeoxynucleotides (CpG-ODN), with the aim of boosting the effectiveness of immunotherapy in combatting hypersensitivity.

Methodology

  • In the study, an aerosol formulation of biodegradable, biocompatible, and non-toxic gelatin nanoparticle-bound CpG-ODN 2216 was used to treat equine recurrent airway obstruction.
  • Samples of Bronchoalveolar lavage fluid were collected from both healthy and allergic horses to measure Th1/Th2 cytokine levels before and after administering the inhalation treatment.
  • Comprehensive clinical examinations were also carried out to determine the therapeutic effectiveness of the nebulized gelatin nanoparticle-based CpG formulation.

Key Findings

  • The most notable finding was that the expression of the regulatory anti-inflammatory and anti-allergic cytokine known as IL-10 was significantly activated after five consecutive inhalations.
  • Close evaluation of clinical parameters following the nanoparticle treatment pointed to a partial remission of the symptoms linked to allergies.

Implications and Conclusion

  • This research is groundbreaking, as it demonstrated for the first time the effectiveness of a colloidal nanocarrier-mediated immunotherapy approach in food-producing animals.
  • It posits that this treatment methodology has the potential to be applied to other species, including humans, in the future.
