İskemik ön koşullanma ve sonradan koşullanma mekanizmaları olarak intraselüler sinyalizasyon ve adenozin

Abstract

Özet

İskemi reperfüzyon hasarı, deoksijene dokunun resirkülasyonu sırasında oluşan patofizyolojik değişiklikler serisidir. İskemi reperfüzyon hasarının potansiyel mekanizması; hipoksiyi, reperfüzyon ile salınan serbest oksijen radikallerini ve inflamatuvar medyatörleri içermektedir. Primer iskemik hasar; son ürünlerin ve kan akımının azalmasına bağlı oluşan anaerobik metabolizmanın toksik ürünlerinin birikimi sonucunda ortaya çıkmaktadır. Ancak, reperfüzyon hasarı nda, serbest oksijen radikallerinin, doku hasarına doğrudan kendileri etkiyerek ve hücresel antioksidan sistemleri yetersizleştirmesi yatmaktadır. İskemik ön koşullanmada lokal olarak salınan agonistler; sinyalizasyon yolunu, G proteinine bağlı olan reseptörlerin aktivasyonu yoluyla tetikler. İskemik ön koşullanma yoluyla olan adaptasyon; adenozin etkisi ile oluşan, KATP (Potasyum-ATP) kanal aktivasyonu tarafından yaratılır. İskemik sonradan koşullanmanın ise; ERK ½ (Ekstraselüler sinyal regüle kaskad ½) ile mitokondriyal KATP kanallarının aktivasyonuna ve NO (Nitrik oksit) üretimine bağlı olduğu ve anılan fenomenin koruyucu etkisi için adenozin reseptörlerinin kullanıldığı ve gunilil siklaz ile PI3 (Fosfatidil inozitol3)-kinaz aktivasyonuna gereksinim olduğu ileri sürülmüştür.

Anahtar sözcükler: Adenozin, intraselüler sinyalizasyon, iskemik, ön koşullanma, sonradan koşullanma.

Abstract

Ischemia reperfusion injury is the series of pathophysiological changes occurring in consequence of recirculation in the deoxygenated tissue. The potential mechanism of ischemia reperfusion injury includes tissue hypoxia, free oxygen radicals arising from the course of reperfusion, and inflammatory mediators. Primary ischemic injury appears as a consequence of accumulation of end products and toxic products of anaerobic metabolism which is occurred by insufficient circulation. But, in the concept of reperfusion injury; free oxygen radicals directly causes tissue injury via affecting themselves and producing inadequacy of cellular antioxidant systems. In ischemic pre - conditioning, locally released agonists trigger signalization way via activating receptors which are bounded to G protein. The adaptation via ischemic pre - conditioning is created by activation of KATP (Potassium-ATP) channels by the effect of adenosine. In the aspect of ischemic post - conditioning; it is propounded that this phenomenon depends on activation of mitochondrial KATP channels and ERK ½ (extracellular signal-regulated kinase cascade) and production of NO (Nitric oxide) and for the protective effect of the mentioned phenomenon, adenosine receptors are used and activation of PI3 (phosphatidyl inositol3) - kinase and guanylyl cyclase are needed.

Keywords: Adenosine, intracellular signalization, ischemic, preconditioning, post conditioning.
