Introduction
Chitosan is the deacetylated derivative of chitin, a polysaccharide found in the exoskeletons of crustaceans and in the cell walls of fungi. In addition to its role in drug delivery, chitosan acts as an adjuvant, owning to its immunostimulatory activity. Chitosan stimulates the immune system by activating the NLRP3 inflammasome, leading to potent IL‑1b production. When tested in experimental models of vaccination, chitosan elicits a balanced Th1/Th2 response.
