Modulation of Th1/Th2 Immune Responses by Killed Propionibacterium acnes and Its Soluble Polysaccharide Fraction in a Type I Hypersensitivity Murine Model: Induction of Different Activation Status of Antigen-Presenting Cells
IL-5 synthesis by spleen cells. Spleen cells from mice treated with saline (Sal), P. acnes (Pa), or PS were obtained 14 days after HEW implantation and intracellularly stained with fluorochrome-conjugated monoclonal anti-IL-5 antibody. Percentages obtained by flow cytometric analysis (a) were converted to absolute numbers of IL-5+ spleen cells (b). **; ***.
