The in vitro effect of guaraná (Paullinia cupana) extract on human peripheral blood mononuclear cells exposed to a high glucose level

چکیده
Background Nowadays, Type 2 Diabetes Mellitus (T2D) affects a significant percentage of the world population. Due to the high levels of glucose, it causes several damages to the cells and, consequently, to the organism. Plants, such as guaraná (Paullinia cupana), which present bioactive compounds, could help somehow in the treatment of diabetes and other chronic diseases. Studies have shown that guaraná extract, rich in compounds like methylxanthines, theobromine and theophylline, presents many beneficial effects to the organism, such as antioxidant capacity, modulation of nitric oxide intracellular levels, as well as anti-obesity and anti-inflammatory capacity.

Effect of Myeloma-Derived Microparticles on in Vitro Proliferation and Viability of Alloimmune Human Peripheral Blood Mononuclear Cells
Background: Microparticles (MPs) are small vesicles released from the cell membrane. Accordingly, these contain active molecules to mediate biological processes, including cell proliferation and cell cycle progression. The fusion of myeloma cell lines with immunized B lymphocytes is a critical step of hybridoma technology. MPs modulate lymphoproliferation, thereby facilitating B cell expansion ...
