| The body uses humoral and cellular immune responses to reject a transplanted graft. |
| Both humoral and cell-mediated immune mechanisms influence the outcome of the infection. |
| Thus, defects in either cell type have the potential to affect both cellular and humoral immunity to varying degrees. |
| Furthermore, children with humoral immunodeficiencies often have infections in other sites such as ears, lung, and skin. |
| Still, some cell-mediated and humoral immune system responses may be slightly impaired by heavy marijuana use. |
| Infection with T gondii induces both cellular and humoral immune responses. |
