1 | The general scheme shown in Fig. 8 is assumed to represent sufficiently well the real physiological interactions between the host cells and the parasites |
2 | Reticulocytes are produced and released from the bone marrow at a rate of Pt and with a remaining maturation time of 121 ARRt, at the end of which they become mature RBCs |
2.1 | Reticulocytes are not subject to random or senescent death as they become mature RBCs within one to 2Â days after entering circulation |
2.2 | Reticulocytes may be infected by the parasite |
3 | Mature RBCs are, theoretically, allowed to live for up to 160Â days |
3.1 | Random death removes 10% of all produced RBCs |
3.2 | Senescent death follows a hazard function that causes RBCs to have a mean lifespan of 98Â days |
3.3 | Mature RBCs can be lost due to invasion by a parasite |
3.4 | Mature RBCs may be lost due to the bystander effect |
4 | Free merozoites live only for 1Â h, during which time they infect reticulocytes and RBCs |
4.1 | Merozoites have a reported 477.2:1 preference for reticulocytes over RBCs |
4.2 | Among mature RBCs, merozoites have an age preference that leads a younger RBC to be two times more likely to be infected than a RBC 11Â days older |
5 | Infected RBCs live for 2Â days and then burst, releasing a new brood of merozoites |
5.1 | Infected RBCs are removed by the immune response |
