High proliferative responses of case 1 PBMC are attributed to CD4⁺ T cells but in the presence of CD56⁺ NK cells. (a) Responses to PBMC unfractionated or deprived of CD4⁺ cells to Aedes albopictus extracts. (b) Flow cytometry of PBMC cultured for 10 days with IL‐2 or Aedes albopictus extracts. (c) Responses to Aedes albopictus extracts of purified CD4⁺, CD8⁺, CD56⁺, mixture of CD4⁺ and CD56⁺, and mixture of CD8⁺ and CD56⁺ cells.
