Association between age and cellular immune response to different influenza A virus strains.
<p>The potential and the shape of association between age and T-cell response against A/H3N2/Min/11/10, A/H3N2/Ind/08/11 and A/H1N1/Cal/07/09 is shown for HD (left panels) and HIV+ (right panels) was analyzed by linear regression model. Departure from linear trend was assessed by model based likelihood ratio test (LTR) to assess the model including age as polynomial predictor.</p
Correlation between humoral immune response to H3N2v strains.
<p>(A): The correlation between HAI titers to A/H3N2/Min/11/10 and to A/H3N2/Ind/08/11 is shown in HD. Pearson's r<sup>2</sup> and significance, as well as the calculated regression line. (B): The correlation between HAI titers to A/H3N2/Min/11/10 and to A/H3N2/Ind/08/11 is shown in HIV+. Pearson's r<sup>2</sup> and significance, as well as the calculated regression line.</p

Cellular immune response to different influenza A virus strains.
<p>(A): The frequency of T-cell response specific for A/H3N2/Min/11/10, A/H3N2/Ind/08/11 and for A/H1N1/Cal/07/09 was evaluated by ELISpot assay in HD (n = 45, white bars) and HIV+ patients (n = 46 grey bars). Results are indicated as SCFs/10<sup>6</sup> peripheral mononuclear cells (PBMCs). Statistical analysis was performed using non parametric Mann-Whitney assay. ** p<0.0001. (B): The correlation between T-cell response against A/H3N2/Min/11/10 and A/H3N2/Ind/08/11 is shown, with Pearson's r<sup>2</sup> and significance, as well as the calculated regression line. HD and HIV+ are reported as white and black circles, respectively.</p
Association between age and humoral immune response to different influenza A virus strains.
<p>Age-related relationships of HAI titer against A/H3N2/Min/11/10, A/H3N2/Ind/08/11 and A/H1N1/Cal/07/09 in either HD (left panels) or HIV+ patients (right panels) was assessed by linear regression model. Departure from linear trend was assessed by model based likelihood ratio test (LTR) to assess the model including age as polynomial predictor.</p
