The polar nucleoside drug ribavirin is front-line treatment for chronic hepatitis C virus infection. The human equilibrative nucleoside transporter (ENT) 1 transports ribavirin into erythrocytes where it is phosphorylated. These phosphorylated metabolites accumulate in the erythrocytes and produce dose-limiting hemolytic anemia. Here, we examined the in vitro and ex vivo transport and metabolis...

Candida albicans hydrophilic yeast cells specifically adhere to mouse macrophages in the splenic marginal zone and in lymph node subcapsular and medullary sinuses. These macrophages express sialoadhesin that binds erythrocytes, but binding of yeast cells is not mediated by sialoadhesin because (i) erythrocytes did not block yeast cell binding, (ii) yeast cell adherence was unaffected by siaload...

A previous study (15) has shown tha t transplantable mouse tumors differ in their capacity to grow progressively in rats pretreated with lyophilized mouse tumor tissue. An inverse correlation was found between the degree of strain specificity of tumors in mice and their transplantability to Pretreated rats. The present study deals with the correlation found between the transplantability of mous...

The presence of antiglobulin factors in normal mouse serum was studied. Mice were injected with human 0 Rh(+) erythrocytes and the resulting gamma globulins were digested with papain. The reaction was demonstrated by agglutinations of human 0 Rh (+) perythryocytes sensitized with the Fab fragments when treated with normal mouse serum. Studies suggested that there are two factors in mice, a 7S A...
