Erythrocytes from humans with Melanesian elliptocytosis are resistant to invasion by Plasmodium falciparum in vitro and epidemiological evidence suggests they may be resistant to P. vivax and P. malariae. We have examined the ability of P. knowlesi merozoites to invade Melanesian elliptocytes in vitro as a definitive means of examining these cells for resistance to invasion by malarial species with different receptor requirements. The Melanesian elliptocytes were highly resistant to invasion by P. knowlesi merozoites showing that the resistance associated with this erythrocyte variant lies at a level common to the invasion pathway(s) of P. falciparum and P. knowlesi. This makes Melanesian elliptocytosis unique as no other human erythrocyte variant has been shown to be resistant to invasion by both species.
患有美拉尼西亚椭圆形红细胞增多症的人的红细胞在体外对恶性疟原虫的入侵具有抗性,流行病学证据表明它们可能对间日疟原虫和三日疟原虫也具有抗性。我们已经研究了诺氏疟原虫裂殖子在体外侵入美拉尼西亚椭圆形红细胞的能力,以此作为检测这些细胞对具有不同受体需求的疟原虫物种入侵抗性的决定性方法。美拉尼西亚椭圆形红细胞对诺氏疟原虫裂殖子的入侵具有高度抗性,这表明与这种红细胞变体相关的抗性存在于恶性疟原虫和诺氏疟原虫入侵途径的共同水平。这使得美拉尼西亚椭圆形红细胞增多症独一无二,因为没有其他人类红细胞变体被证明对这两种疟原虫的入侵都具有抗性。
