title: [Effect of N-3 polyunsaturated fatty acids on the modulation of T lymphocytes in vitro and redox status in obese women with hypertension].
abstract: OBJECTIVE
  Deepen our knowledge of the immune system alterations associated with obesity-related hypertension and demonstrate that polyunsaturated fatty acids can enhance the proliferation and their profile oxidant/antioxidant and subsequently involved in the strategy prevention and treatment in obese hypertensives.
  
  
  METHODS
  T cells are isolated from the blood of the control and obese women with hypertension the University Hospital of Tlemcen (Algeria), these cells are incubated in the presence of a synthetic mixture of PUFA to 30μM (DHA/EPA/LA) and stimulated by mitogens for 48hours. The cells are counted and used to assess intracellular oxidative status. The biochemical parameters are determined by the use of plasma.
  
  
  RESULTS
  In obese women with hypertension, a significant increase in plasma levels of (glucose, uric acid, creatinine, urea, total cholesterol and triglycerides) compared to controls. In addition, decreased cell proliferation, basal or stimulated by Con A was observed in obese women with hypertension compared with controls. The mixture of PUFA to 30μM reduced lymphoproliferation as well in obese women with hypertension than in controls. The rates in malondialdéhyde (MDA) and protein carbonyl lymphocytes are elevated in hypertensive obese women. PUFA supplementation to 30μM seems correct this redox status in hypertensive obese since rates in protein carbonyl, are similar to those of controls.
  
  
  CONCLUSIONS
  The mixture of PUFA (n-3 and n-6) can modulate the activity of T lymphocyte proliferation and correct the intracellular redox status in hypertensive obese women.
