Effect of shark liver oil on peritoneal murine macrophages in responses to killed-Candida albicans

ABSTRACT

Shark Liver Oil [SLO] is an immunomodulator. Macrophages play a key role in host defense against pathogens like fungi. Candida albicans have mechanisms to escape immune system. We determined the effect of killed-Candida on the in vitro viability of macrophages and the effect of SLO on augmentation of this potency. Peritoneal macrophages were separated and cultured [3-105/well]. At first, the effect of killed-Candida [200 cells/well] on macrophage viability was evaluated, using MTT test. Then, MTT was performed on macrophages stimulated with killed-Candida in the presence of SLO. Killed-Candida suppressed the ability of MTT reduction and hence macrophages viability [P=0.026], but addition of SLO [100 mg/ml] significantly enhanced cell viability [P=0.00]. So, SLO could neutralize the inhibitory effect of Candida. Simultaneous with cytotoxic effect of killed-Candida cells on macrophages viability, SLO augment macrophages viability. So, it can be applied in candidiasis as a complement
