Passive immunization with monoclonal antibodies (MAbs) to melanin prolonged the survival of and reduced the fungal burden in Cryptococcus neoformans-infected mice in comparison to controls. MAbs to melanin reduced the growth rate of in vitro-melanized C. neoformans cells, suggesting a new mechanism of antibody-mediated protection.
