An 11-year-old Warmblood gelding was presented for inspiratory stridor and dysphagia. Based on history and clinical examination, a solitary mass localised in the oropharynx was suspected. Due to its inaccessibility and defensive behaviour of the horse, it was difficult to visualise this mass either by upper airway endoscopy or by oral examination and the conventional imaging methods (radiology and ultrasound) provided only limited information. Fine needle aspiration cytology was suggestive of lymphoma, but the exact localisation and the extent of tissue infiltration of the tumour could only be defined by magnetic resonance imaging (MRI). MRI has proved to be a very useful diagnostic tool in equine lameness investigation and, as this case illustrates, it has considerable diagnostic potential for soft tissue examination of the equine head.

UNLABELLED CpG-oligodeoxynucleotides (CpG-ODNs) interact with dendritic cells (DCs), but evidence is less clear for CpG-ODN admixed with or incorporated into vaccine delivery vehicles. We loaded alginate-coated chitosan-nanogels (Ng) with class-A or class-B CpG-ODN, and compared with the same CpG-ODNs free or admixed with empty Ng. Experiments were performed on both porcine and human blood DC subpopulations. Encapsulation of class-A CpG-ODN (loading into Ng) strongly reduced the CpG-ODN uptake and intracellular trafficking in the cytosol; this was associated with a marked deficiency in IFN-α induction. In contrast, encapsulation of class-B CpG-ODN increased its uptake and did not influence consistently intracellular trafficking into the nucleus. The choice of CpG-ODN class as adjuvant is thus critical in terms of how it will behave with nanoparticulate vaccine delivery vehicles. The latter can have distinctive modulatory influences on the CpG-ODN, which would require definition for different CpG-ODN and delivery vehicles prior to vaccine formulation. FROM THE CLINICAL EDITOR This basic science study investigates the role of class-A and class-B CpG-oligodeoxynucleotides loaded into alginate-coated chitosan nanogels, demonstrating differential effects between the two classes as related to the use of these nanoformulations as vaccine delivery vehicles.
