Propolis Demonstrates Anti-Parasitic Capacity

Though Sandflies may not be a problem for some, one bite can induce Leishmaniasis, a potentially fatal disease, as stated in Wikipedia. Fortunately, researchers are exploring the anti-parasitic properties of Propolis, yet another of it's amazing qualities. Thanks to Apitherapy, these discoveries are essentiel for emerging nations lacking in medicinal or financial solutions.

The Effect of Propolis on CCL5 and IFN-γ Expression by Peripheral Blood Mononuclear Cells from Leishmaniasis Patients

Mucocutaneous leishmaniasis is associated with a strong Th1 immune response to Leishmania, which modulates chemokines and their receptors expression, affecting their migratory capacity. There are no antileishmanial vaccines available and chemotherapy still relies on the potentially toxic pentavalent antimonials.

Propolis is a bee product with immunomodulatory and antiparasite activities, and researchers have been attracted to its potential for the development of new drugs.

This work investigated the effects of propolis on CCL5 and IFN-γ expression by peripheral blood mononuclear cells (PBMC) in order to evaluate a possible immunomodulatory action of propolis in patients with leishmaniasis compared to healthy control subjects.

PBMC were incubated in the absence or presence of propolis and the evaluation of a possible cytotoxicity of propolis was carried out using MTT assay. The expression level of CCL5 and IFN-γ was determined by real-time PCR.

Key Findings
Our data indicated that propolis modulates the immune response of leishmaniasis patients in vitro, affecting CCL5 and IFN-γ expression by PBMC.

Data suggested that propolis drives an anti-inflammatory response depending on concentration. Although propolis is a potential source of new and selective drugs for the treatment of leishmaniasis, its usefulness in the therapeutics should be further investigated.
