Moringa oleifera is used in traditional medicine as well as in food, cosmetic, and pharmaceutical industries. Water-soluble M. oleifera lectin (WSMoL) is an anionic protein isolated from the seeds. This work investigated the immunomodulatory effects of WSMoL on human PBMC. Measurement of cytokine and nitric oxide levels and immunophenotyping assays were investigated. PBMC were incubated with WSMoL (10µg/mL) for 24 h, 48 h and 72 h, and was performed immunophenotyping of lymphocytes and monocytes. Culture supernatants were used to determined cytokine and nitric oxide levels. WSMoL induced the release of the cytokines TNF-a, IL-2, IL-6, IL-10 as well as of nitric oxide. Incubation of PBMC with this lectin also led to activation of CD8+ T lymphocytes. WSMoL promotes immunomodulation in human PBMC inducing a potential wound healing profile and, in future in vivo assays, can be evaluated as adjuvant in immunosuppressive diseases and wound repair.
