腺苷(adenosine)是机体本身所存在的一种生物活性物质,有着较广泛的生物学效应。在免疫系统中,腺苷能够抑制机体中的许多免疫反应。近年来,许多实验发现,经腺苷处理了的人类外周血T淋巴细胞,有部份T细胞会丧失与绵羊红细胞(SRBC)形成玫瑰花的能力,而另一部份T细胞(主要部份)仍保持着与SRBC形成玫瑰花的能力。前者被 Adenosine (aosin) is a bioactive substance that exists in the body itself and has a wide range of biological effects. In the immune system, adenosine can inhibit many of the immune response in the body. In recent years, many experiments have found that some T cells in adenosine-treated human peripheral blood lymphocytes lose the ability to form roses with sheep erythrocytes (SRBC), whereas the other T cells (the major part ) Still maintain the ability to form roses with SRBC. The former is
