AT the 34° Congresso Nazionale della Società Italiana di Farmacologia in Rimini, Palacongressi, 14-17 Ottobre 2009 Mariateresa Cipriano and colleagues presented data on the role of PEA in vitro, in the modulation of angiogenetic response in Abeta-challenged glial cells.(Alzheimer model).
Glial cells were cultured in 10% FCS supplemented DMEM and treated with 1 mg/mL of Ab (1-42) in the presence of PEA, at concentration of 10-8 to 10-6 molair.
PEA reduced the pro-angiogenic response induced by beta amyloid-stimulus in glial cells. PEA treatment decreased both the transcription and expression of the main vasoactive factor, VEGF. Moreover, PEA reduced the expression of an other essential pro-angiogenic mediator, TNF-a, and the presence of MMP-9, a protein strongly involved in the degradation of extracellular matrix, necessary to allow the vessel progression.
