Cryptococcal meningoencephalitis is a life-threatening infectious disease in immunocompromised patients. Unmethylated CpG-oligodeoxynucleotides (CpG-ODN) protects hosts in a mouse model. In the present study, we tested the adjuvant effect of CpG-ODN in anti-fungal chemotherapy. Administration of either fluconazole (FLCZ) or CpG-ODN was effective in extending survival, accelerating clearance of fungi and preventing disseminated infection. Combination of both agents provided more beneficial effect than either agent alone. Cytokine balance in the infected lungs was biased to Th1-type response by CpG-ODN, while FLCZ did not further promote. These results suggest that CpG-ODN is a promising adjuvant in chemotherapy against this infection.
