Th2 response to HPV6 and HPV11 antigens among wart patients and healthy controls. PBMCs were stimulated with either HPV-6 or HPV-11 recombinant antigen in vitro and percent frequency of CD4⁺ T cell subset producing IL-4 was determined relative to unstimulated control. a Cumulative scatter plots showing percent frequency of CD4⁺ T cells producing IL-4⁺ in response to HPV-6 antigen in wart patients (n = 65) and healthy controls (n = 25); b HPV-11 specific percent frequency of CD4⁺ T cells producing IL-4 in wart patients and healthy controls is shown as a cumulative scatter plot. P value <0.05 was considered significant and <0.001 as highly significant
