dendritic cell (DC) based vaccine is a promising strategy for cancer immunotherapy. However, clinical trials have shown only limited efficacy, demonstrates the need to optimize protocols for Human DC vaccine preparation. In this study, we systematically compared five different Human vaccines DC maturation protocols used in clinical trials: (1) four-cytokine cocktail (TNF-α, IL -6, IL -1β, and PGE2); (2) cocktails α-DC-cytokine (TNF-α, IL -1β, IFN-α, IFN-γ, and poly I: C); (3) lipopolysaccharide (LPS) / IFN-γ; (4) TNF-α and PGE2; and (5) Trimix (mRNA encoding CD40L, CD70, and constitutively activated Toll-like receptor 4 electroporated into immature DC).
We found that four cytokine cocktail induced high levels of costimulatory and HLA molecules, and CCR7, in DC. Mature DC (MDCs) matured with a cocktail of four cytokines have higher viability than those obtained with other protocols. Based on these features, we chose four cytokine cocktail protocols to further enhance the ability of immunization of DC by introducing exogenous genes. We show that the introduction of exogenous Bcl-2 increased DC survival. Furthermore, introducing the IL – 12p70 rescued inhibition of IL -12 secretion by PGE2 without damaging the DC phenotype.
Introducing both Bcl-2 and IL – 12p70 mRNA into DC induced enhanced cytomegalovirus pp65-specific CD8 + T cells secreting IFN-γ and TNF-α , Taken together, our data demonstrate that DCs matured by a cocktail of four cytokines combined with exogenous Bcl-2 and IL – 12p70 gene expression is a promising approach for clinical applications in cancer immunotherapy.

Mycobacterium avium subsp. paratuberculosis MAP1889c Protein Induces Maturation of Dendritic cells and Th2-biased Drives Immune Responses.
Mycobacterium avium subsp . paratuberculosis (MAP) is the causative agent of chronic granulomatous bowel disease in animals and is associated with various autoimmune diseases in Human including Crohn’s disease. A good understanding of host-protective immune response and antibacterial immunity is controlled by MAP and its components may contribute to the development of effective control strategies.
MAP1889c seroreactive identified as an antigen in patients with Crohn’s disease. In this study, we investigated the immunological function of MAP1889c in dendritic cells (DC). MAP1889c stimulated DC to increase the expression of molecular co-stimulatory (CD80 and CD86) and molecular complex class major histocompatibility (MHC) and the secret interleukin higher ( IL ) – 10 and moderate IL -6, tumor necrosis factor (TNF) -α, and IL – 12p70 level through Toll-like receptor (TLR) 4 lanes.
MAP1889c-induced DC activation mediated by mitogen-activated protein kinases (MAPKs), cAMPp-response element binding protein (CREB), and nuclear factor kappa B (NF-kB). In particular, the signal is essential for MAP1889c CREB-mediated IL -10 production but not TNF-α and IL – 12p70 . In addition, DC-mature MAP1889c induced T cell proliferation and drove Th2 response.

Production of lipopolysaccharide (LPS) -mediated pro-inflammatory cytokines and anti-inflammatory cytokine is suppressed and increased respectively by MAP1889c pretreatment in DC and T cells addition, treatment MAP1889c in M. avium -infected macrophages promoted the growth of intracellular bacteria and IL -10 production. These findings indicate that MAP1889c antimycobacterial modulate the host response and can be a potential virulence factor for MAP infection.
