Anti-NXT-2 antibodies inhibit biofilm formation and increase opsonophagocytic killing. Candida albicans biofilms were incubated with heat-inactivated plasma from (A) CA.KEX1-, NXT-2-, or SHAM-immunized mice and (B) NXT-2- or SHAM-immunized rhesus macaques, with reduced formation in wells with plasma from vaccinated mice and NHPs. (C) and (D) Opsonophagocytic killing of C. albicans and A. fumigatus by macrophages was evaluated in presence of plasma from CA.KEX1-, AF.KEX1-, NXT-2-, and SHAM-immunized mice. Plasma from CA.KEX1-, AF.KEX1-, and NXT-2-immunized mice significantly enhanced fungal killing compared to SHAM. Results are presented relative to macrophage killing of fungi without any added plasma. Statistical significance was determined by Mann–Whitney tests and one-way ANOVA. *≤ 0.05, ** < 0.01, and *** < 0.001.
