Figure Lengend Snippet: The effect of vitamin E supplementation on cytokine production depends on baseline cytokine production. Cytokine production was measured from whole blood at the beginning and end of a one year vitamin E supplementation in the elderly. TNF-α, IL-1β, and IL-6 was measured from whole blood elicited for 24 hours with lipopolysacchride (LPS; 1.0 µg/mL). IFN-γ was measured from whole blood elicited for 48 hours with phytohemagluttinin (PHA; 20 µg/mL) or concalavinA (ConA; 40 µg/mL). Cytokines production was corrected for the number of monocytes and lymphocytes in the blood (pg/ 106 lymphocyte and monocyte). P values (P) for the interaction are unadjusted.

Quantification of CD4 + CXCR5 + IL-4 + T FH cells and CD4 + CXCR5 + T FH cells comparing those outside and within GCs from each of five different areas in TLOs of 17 patients with IgG4-RD (G1–G17).
