Quantitative proteomics of non hodgkin's

Abstract: ArtinM, a D-mannose-binding lectin from Artocarpus heterophyllus induces the activation of a Mast cell, neutrophils, macrophages, and CD4+ and CD8+ T cells, via carbohydrate recognition. we previously reported, that ArtinM is able to induce IL-17 and IL-12p40 production in murine B cells. Here, we further investigated the effects of ArtinM on murine B lymphocytes and Raji and Daudi cells, both human cell lines derived from non-Hodgkin lymphoma. We showed that ArtinM did not induce cell proliferation and low levels of IL-2, IFN-γ, and IL-12 were produced by murine B cells. However, high concentrations of ArtinM induced apoptosis of murine B cells. Then, evaluated the cytotoxic effect of ArtinM lectin against Raji and Daudi cells. we observed the ArtinM ability to reduce cell growth and cell viability, with a more pronounced cytotoxic effect on Raji cells. In addition, we observed the absence of DNA fragmentation, a strong indication of the exclusion of the apoptosis cascade via mitochondrial pathway, and the possible involvement of PTK, kinases of Src family, and CD45 phosphatase activity under Lck molecule in the cytotoxic effect of ArtinM in the Raji and Daudi cells. Thus, the present work demonstrates the limitations of the immunomodulatory effect of ArtinM under murine B cells, and provides insights in the investigative field in the non-Hodgkin lymphoma treatment, via carbohydrate recognition.
