The emergence of mucosal healing as a treatment goal that could modify the natural course of Crohn's disease and the accumulating evidence showing that biologics are most effective in achieving mucosal healing, along with the success of early treatment regimens for rheumatoid arthritis, have led to the identification of early Crohn's disease and development of the concept of catching the therap...

BACKGROUND/AIMS Mucosal healing (MH) is a proposed therapeutic goal for patients with ulcerative colitis (UC). Whether MH is the final goal for UC, however, remains under debate. Therefore, to elucidate clinical variables predicting relapse after MH in UC could be useful for establishing further therapeutic strategy. The aim of this study is to evaluate the predictive variables for relapse in U...

The protective role of interleukin (IL)-12 against influenza infection was assessed by analyzing the efficacies of orally administered clarithromycin (CAM) as an immunomodulator and intranasal administration of recombinant IL-12 in intranasally influenza virus-infected mice. In infected mice, CAM at 20 mg/mouse/day significantly elevated the levels of IL-12 and interferon-gamma on days 2 and 3,...

BACKGROUND β-Glucans have been shown to function as a potent immunomodulator to stimulate innate and adaptive immune responses, which contributes to their anti-tumor property. However, their mechanisms of action are still elusive. Glucocorticoid-induced TNF receptor ligand (GITRL), a member of the TNF superfamily, binds to its receptor, GITR, on both effector and regulatory T cells, generates a...

Apoptosis mediated by Fas ligand (FasL) interaction with Fas receptor plays a pivotal regulatory role in immune homeostasis, immune privilege, and self-tolerance. FasL, therefore, has been extensively exploited as an immunomodulatory agent to induce tolerance to both autoimmune and foreign antigens with conflicting results. Difficulties associated with the use of FasL as a tolerogenic factor ma...
