Flow cytometric analyses showed that TGF-beta2 does not suppress the upregulation of MHC (major histocompatibility complex) class II molecules and the T cell stimulatory capacity of human DC that were stimulated with a strong cytokine cocktail containing tumor necrosis factor alpha (TNF-alpha), IL-1beta, IL-6 and prostaglandin E2 (PGE2).

Although both mature and immature DC expressed comparable amounts of the TGF-beta receptor type II, Smad2 phosphorylation and subsequent upregulation of Smad7 was inhibited in mature DC, but not immature DC.

However, further analysis revealed that mature DC alone are not sufficient to mediate full T cell activation in the presence of TGF-beta2, unless IL-12 is added to the DC/T-cell coculture.

Finally, we demonstrate that MHC class II expression and IL-12 secretion by DC are not disturbed by TGF-beta2 after DC stimulation with a modified maturation cocktail containing the Toll-like receptor (TLR)-ligands Poly I:C or R848, TNF-alpha, IL-1beta and INF-gamma.

Tumor lysate-pulsed DCs were rendered TGF-beta insensitive by dominant-negative TGF-beta type II receptor (TbetaRIIDN), leading to the blockade of TGF-beta signals to members of the Smad family, which are the principal cytoplasmic intermediates involved in the transduction of signals from TGF-beta receptors to the nucleus.

Phosphorylated Smad-2 was undetectable and expression of surface co-stimulatory molecules (CD80/CD86) were upregulated in TbetaRIIDN DCs after antigen and TGF-beta1 stimulation.

Vaccination of C57BL/6 tumor-bearing mice with the TbetaRIIDN DC vaccine induced potent tumor-specific cytotoxic T lymphocyte responses against TRAMP-C2 tumors, increased serum IFN-gamma and IL-12 level, inhibited tumor growth and increased mouse survival.

Specifically, we verify the prediction that the node SMAD is over-active in leukemic T-LGL by demonstrating the predominant phosphorylation of the SMAD family members Smad2 and Smad3.

The antisera neutralized TGF-β1-induced growth-inhibition on mink lung epithelial cells (Mv1Lu) and attenuated TGF-β1-induced Smad2/3 phosphorylation, α-SMA, collagen type 1 alpha 2 (COL1A2), plasminogen activator inhibitor-1 (PAI-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) expression in the rat hepatic stellate cell (HSC) line, HSC-T6.

Vaccination against TGF-β1 with the kinoids significantly suppressed CCl4-induced collagen deposition and the expression of α-SMA and desmin, attenuated hepatocyte apoptosis and accelerated hepatocyte proliferation in BALB/c mice.

Our study aimed at optimizing the antitumor effects of the B16F10/glycosylphosphatidylinositol-interleukin 21 (B16F10/GPI-IL-21) tumor vaccine on melanoma bearing mice by combining the TGF-β1 knockdown and the administration of miR200c agomir.

The later combination showed that, when compared with the mice in the control group that received no vaccination, vaccinated mice significantly increased NK and CTL activities, enhanced levels of IFN-γ, and reduced expression of TGF-β1, N-cadherin, Vimentin, Gli1/2, P-Smad2/3 and others involved in promoting expression of EMT-related molecules in tumor areas, and inhibited the melanoma metastasis in lungs and lymph nodes.
