Interferon-gamma treatment or transduction of the class II transactivator (CIITA) gene induces class II expression but also up-regulates the class II-associated accessory molecules, invariant chain (Ii) and DM.

|
To determine if interferon-gamma treatment and CIITA transduction are potential immunotherapies, we assessed the tumorigenicity of sarcoma cells expressing combinations of class II, Ii, and DM.

|
Since we hypothesized that class II-transfected tumor cells not coexpressing Ii and DM present endogenously encoded tumor peptides, we have assessed the transfectants for antigen presentation activity to MHC class II-restricted antigen-specific CD4(+) T cells.

Absence of the Ii protein, which normally blocks the antigenic-peptide-binding site of MHC class II molecules at synthesis in the endoplasmic reticulum, presumably increases the range of cancer-related epitopes presented to CD4+ helper T cells.

Infection of mice with Dam(+) Salmonella resulted in the induction of host genes known to be indicators of IFN bioactivity and regulated by either IFN-alpha/beta (Mx1) or IFN-gamma (class II transactivator protein [CIITA] and inducible nitric oxide synthase [iNOS]) or by both IFN-alpha/beta and IFN-gamma (RNA-specific adenosine deaminase [ADAR1] and RNA-dependent protein kinase [PKR]) in a tissue-specific manner compared to uninfected animals.
|
46 |
12228285
|
Since the Mx1 promoter is IFN-alpha/beta specific and the Mx1 gene is not inducible directly by IFN-gamma, these data suggest a role of IFN-alpha/beta in the host response to Salmonella infection.
|
47 |
12228285
|
Finally, although no Dam(-) organisms were recovered from the liver or spleen after oral infection of mice, ADAR, PKR, Mx, and CIITA expression levels were elevated in these tissues relative to those in uninfected mice, suggestive of the distant action of a signaling molecule(s) in the activation of ISG expression.

Tumor cells transduced with the MHC class II Transactivator and CD80 activate tumor-specific CD4+ T cells whether or not they are silenced for invariant chain.
|
84 |
16424052

Because expression of multiple MHC II alleles would facilitate presentation of a broader repertoire of tumor antigens, we have now transduced tumor cells with the MHC class II transactivator (CIITA), a regulatory gene that coordinately increases expression of all MHC II alleles.
|
85 |
16424052
|
To determine if Ii expression affects presentation of MHC class II-restricted endogenously synthesized tumor antigens in human tumor cells, HLA-DR-MCF10 breast cancer cells were transduced with the CIITA, CD80 costimulatory molecule gene, and with or without small interfering RNAs (siRNA) specific for Ii.
|
86 |
16424052
|
Ii expression is silenced >95% in CIITA/CD80/siRNA transductants; down-regulation of Ii does not affect HLA-DR expression or stability; and Ii(+) and Ii(-) transductants activate human CD4+ T cells to DRB1*0701-restricted HER-2/neu epitopes.

The MHC CIITA is a master regulator of MHC class II expression and also induces expression of class I molecules.

Furthermore, our data suggested that coadministration of DNA-encoding calreticulin (CRT) linked to human papillomavirus (HPV) 16 E6 Ag (CRT/E6) with CIITA DNA leads to enhanced E6-specific CD8(+) T cell immune responses in vaccinated mice.
|
123 |
18453624
|
In addition, coadministration of the combination of CRT/E6 DNA with CIITA DNA and DNA encoding the invariant chain (Ii) linked to the pan HLA-DR-reactive epitope (Ii-PADRE) further enhanced E6-specific CD8(+) T cell immune responses in vaccinated mice.
|
124 |
18453624
|
Vaccination with the combination vaccine also led to enhanced E6-specific CD8(+) memory T cells and to long-term protection against TC-1 tumors and prolonged survival in vaccinated mice.
|
125 |
18453624
|
Thus, our findings suggest that the combination of CIITA DNA with CRT/E6 and Ii-PADRE DNA vaccines represents a potentially effective means to combat tumors in the clinical setting.

Furthermore, our data suggested that coadministration of DNA-encoding calreticulin (CRT) linked to human papillomavirus (HPV) 16 E6 Ag (CRT/E6) with CIITA DNA leads to enhanced E6-specific CD8(+) T cell immune responses in vaccinated mice.

In addition, coadministration of the combination of CRT/E6 DNA with CIITA DNA and DNA encoding the invariant chain (Ii) linked to the pan HLA-DR-reactive epitope (Ii-PADRE) further enhanced E6-specific CD8(+) T cell immune responses in vaccinated mice.

Vaccination with the combination vaccine also led to enhanced E6-specific CD8(+) memory T cells and to long-term protection against TC-1 tumors and prolonged survival in vaccinated mice.

Thus, our findings suggest that the combination of CIITA DNA with CRT/E6 and Ii-PADRE DNA vaccines represents a potentially effective means to combat tumors in the clinical setting.

The MHC CIITA is a master regulator of MHC class II expression and also induces expression of class I molecules.

Irradiated CIITA-positive mammary adenocarcinoma cells act as a potent anti-tumor-preventive vaccine by inducing tumor-specific CD4+ T cell priming and CD8+ T cell effector functions.
|
142 |

|
Immunity generated in the TS/A-CIITA-vaccinated mice correlated with an efficient priming of CD4(+) T cells and consequent triggering and maintenance of CD8(+) CTL effectors, as assessed by adoptive transfer assays.
|
143 |

|
Finally, in TS/A-CIITA-vaccinated mice, a statistically significant reduction in the percentage and absolute number of CD4(+) CD25(+) T regulatory cells as compared with those of untreated mice with growing tumors (P < 0.001) or mice vaccinated with TS/A parental cells were observed.

CIITA-driven MHC-II positive tumor cells: preventive vaccines and superior generators of antitumor CD4+ T lymphocytes for immunotherapy.

In our study, we have investigated whether tumors of distinct histological origin can be rejected if expressing CIITA-driven MHC class II molecules.
|
146 |

|
Adoptive cell transfer experiments demonstrated that tumor immunity correlates with the efficient priming of CD4(+) T helper cells and the consequent activation of CD8(+) T lymphocytes.
|
147 |

Importantly, CD4(+) T cells were clearly superior to CD8(+) T cells in antitumor protective function.

The major histocompatibility complex (MHC) class II-associated Invariant chain (Ii) is present in professional antigen presenting cells where it regulates peptide loading onto MHC class II molecules and the peptidome presented to CD4+ T lymphocytes.
|
153 |
22942358
|
We used liquid chromatography coupled with mass spectrometry to sequence MHC II-restricted peptides from Ii+ and Ii- MCF10 human breast cancer cells transfected with HLA-DR7 or the MHC Class II transactivator CIITA to determine if Ii- cells present novel peptides.

Here, we report that patients with melanoma receiving DD immediately before a dendritic cell (DC) vaccine failed to develop a tumor-antigen-specific CD4 and CD8 T-cell immune response even after repeated vaccinations.

First, DD modulated DCs toward tolerance by downregulating costimulatory receptors such as CD83 and CD25 while upregulating tolerance-associated proteins/pathways including Stat-3, β-catenin, and class II transactivator-dependent antigen presentation.

Here, we have addressed the effect of Tollip and MARCH1 on the regulation of MHC II trafficking and TLR signaling.
|
157 |
24600555
|
Our results show that MARCH1-deficient mice splenocytes are impaired in their capacity to produce pro-inflammatory cytokines in response to poly(I:C) and that TLR3 and MHC II molecules interact in the endocytic pathway.
|

|
Knocking down Tollip expression in human CIITA(+) HeLa cells increased expression of HLA-DR but reduced the proportion of MHC II molecules associated with the CLIP peptide.
|
159 |
24600555
|
While overexpression of Tollip did not affect HLA-DR levels, it antagonized the function of co-transfected MARCH1.
|
160 |
24600555
|
We found that Tollip strongly reduced MARCH1 protein levels and that the two molecules appear to compete for binding to MHC II molecules.
|
161 |
24600555
|
Altogether, our results demonstrate that Tollip regulates MHC class II trafficking and that MARCH1 may represent a new Tollip target.

In this chapter, we provide practical methods to create a potent in vivo tumor cell vaccine by inducing MHC Class II and Ii using MHC Class II transactivator (CIITA) or interferon-gamma (IFN-γ) and subsequently inhibiting Ii by antisense oligonucleotides.
