Traditionally, CD4(+) T cells have been separated into two different subsets named T helper (Th)1 and Th2. A new IL-23-driven subset of Th cells called Th(IL-17) has now been described. The data suggest that IL-23 plays an important role in the differentiation of autoreactive pathogenic T cells. Whether these IL-23-induced Th(IL-17) cells are a unique subset or are related to other Th subsets i...

The induction of IL-12 and IL-10 production by the immunomodulatory C3 binding glycoprotein (C3bgp) was studied on human peripheral blood mononuclear cells (PBMC). Isolated PBMC from healthy human donors were cultured 24 hours with C3bgp isolated from Cuscuta europea. We studied also the influence of C3bgp on the cytokine production in LPS-, PHAand PWM-stimulated PBMC. The levels of these cytok...

BACKGROUND Numerous animal model studies have examined the ability of genetically engineered tumor cells to release cytokines and to elicit an immune memory against the parental tumor. Often only a single cytokine is studied, and few comparative studies have been conducted. PURPOSE We evaluated the antitumor efficacy of adenocarcinoma cells engineered to release interleukin (IL)-12 in a mouse...
