| Antibodies to all extracellular domains of ITvar9 were also able to opsonize infected erythrocytes for phagocytosis at high concentration. |
| In humans and animals only M protein typespecific antibodies have the capacity to opsonize streptococci and to override the anti-phagocytic property of M protein. |
| They were also equally unable to opsonize fungal cells in a J774 macrophage phagocytosis and killing assay. |
| The role of B-cells in the immune response is to release antibodies that may opsonize a particular cell and assist T-cells in destruction of that cell. |
