Cytokines and chemokines levels in the plasma of HIV Tg mice. Cytokine and chemokines production was compared among four different groups: (i) FVB/N WT control (WT) (solid circles), (ii) asymptomatic Tg mice without skin lesions (Tg no S) (solid squares), (iii) Tg mice at early stages of lymphadenopathy (pre-L) (solid triangles) and (iv) Tg mice at the late stage of lymphadenopathy (L) (inverted solid triangles). Plasma samples from each group were collected and analyzed in triplicate. Bars denote the standard deviation. The p-values are represented as lines in the figures and were calculated as unequal variance t-test between Tg no S, pre-L and L relative to the WT. The p values for anova are at the bottom of each figure.
