AB  - Multiple  sclerosis  (MS)  is  a  complex  inflammatory,demyelinating disease of central nervous system (CNS). All the essen-tial components of the renin-angiotensin system (RAS) are presentedin  the  mammalian  brain.  The  angiotensin  II  (Ang  II),  biologicallyactive octapeptide is not only a vasoconstrictor, but also a pro-inflam-matory factor. Many of the classical and of the hypothetical functionsof brain Ang II are mediated by stimulation of AT1 receptors (AT1R).Brain AT2 receptors (AT2R) are highly expressed during development.In the adults, AT2R are restricted to areas predominantly involved inthe process of sensory information. The AT2R1332 A/G polymorph-ism was proposed to influence AT2R protein expression, and is themost studied polymorphism in this gene, in other diseases. Recently,the  striking  appearance  of  the  RAS  in  MS  brain  was  described.However, the role of AT2R remains to be clarified. Thus, the aim ofour  study  was  to  establish  if  there  is  an  association  between  AT2R1332 A/G gene polymorphism and predisposition of MS Methods:Subjected  group  consisted  of  122  female  and  70  malepatients with MS and 75 female and 50 male controls from populationof Serbia. Genotyping was done by PCR and restriction digestion withEcoRI enzyme.Results:The  genotype  and  allele  frequencies  for  AT2R1332A/Ggene  polymorphism  are  analyzed  separately  in  females  and  males,since this gene is located on X chromosome. We detected significantoverrepresentation of1332A/G AA genotype (OR 1.6, 95% CI:1.0–2.7, p<0.05) in female patients with MS compared to female controls.In hemizygous males we didn’t found any difference between patientsand controls.Conclusion:The  role  of  RAS  genes  in  MS  was  neglected  untilrecently.  Than,  it  was  shown  that  the  role  of  RAS  in  the  CNS  isbeyond  the  regulation  of  cardiovascular  function.  Until  now  AT2R(1332A/G)  gene  polymorphism  was widely studied  and associatedwith hypertension and other vascular disease. Until now, there wereno studies concerning role of Ang II receptor polymorphisms in MS.This study  suggest  possible  role  of  AT2R in  MS.  Further  studies areneeded to elucidate this result.
