In the current study we show that propolis, a non-toxic natural bee-hive product, suppresses HIV-1 replication and modulates in vitro immune responses. CEM cells were treated with propolis at nontoxic concentrations prior to or following infection with HIV-1. Propolis abolished syncytium formation at 4.5 ug/ml and inhibited it at lower doses in a concentration-dependent manner. Propolis decreased p24 antigen production by as much as 90-100% in a concentration-dependent manner. Furthermore, modulation of peripheral blood mononuclear cells (PBMCs) mitogenic responses upon the addition of propolis was noted, reducing the elevated responses to Concanavalin A (Con A) and enhancing suppressed mitogenic responses to pokeweed mitogen (PWM). In summary propolis may constitute a non-toxic natural product with both anti HIV-1 and immunoregulatory effects.
