FIGURE 3.
Serine increased content of immunoglobulin and decreased content of inflammatory cytokines and colonic infiltration markers. (A–C) IgA, IgG, and IgM concentration in sera. (D–F) IL-1β, IL-6, and TNF-α concentration in colonic tissue. (G,H) MPO and EPO concentration in colonic tissue. Control, mice was rectally administrated with PBS without pretreatment with dextran sulfate sodium; DSS, mice was rectally administrated with PBS after pretreatment with dextran sulfate sodium; Ser, mice was rectally administrated with serine after pretreatment with dextran sulfate sodium. MPO, myeloperoxidase; EPO, eosinophil peroxidase. Values are expressed as mean ± SEM, n = 7. a,bMeans of the bars with different letters were significantly different among groups (P < 0.05).
