Fig. 3From: Anti-erythrocyte antibodies may contribute to anaemia in Plasmodium vivax malaria by decreasing red blood cell deformability and increasing erythrophagocytosisEffects of antibodies on the dynamics fluctuations of nRBC membrane. Modifications in the amplitude of membrane fluctuations of single human RBCs from a healthy donor were examined by DM before and 30 min after the addition of different antibodies: a control, b anti-bacteriophage monoclonal antibody produced in rabbit (non-related IgG), c anti-red blood cell antibody, d IgG purified from sera of healthy individuals, e IgG purified from sera of non-anaemic patients with vivax malaria, and f IgG purified from sera of subjects infected by P. vivax and with anaemia. For each assayed antibody, ten RBCs were evaluated. p values were determined using a paired t testBack to article page
