Abstract
BACKGROUND The host adaptive immune response helps determine which cervical HPV infections persist and progress to precancer and cancer, and systematic characterisation of T-cell infiltration would help inform key steps in cervical carcinogenesis. METHODS A systematic review and meta-analysis were conducted of infiltrating T-cells in normal cervix, low-grade lesions, high-grade lesions, and invasive cancers including epithelial, stromal, and total tissue and the following markers: CD3, CD4, CD8, FoxP3, CD25, and the CD4:CD8 ratio. An additional qualitative review summarised longitudinal data on associations between infiltrating T-cells and cervical disease persistence, regression, progression, or prognosis. RESULTS There were fewer CD3+, CD4+, and CD8+ cells in cervical lesions and more cells in cancers compared to normal epithelium. FoxP3 and CD25+ regulatory T-cell infiltration is high in persistent and precancerous lesions, and longitudinal data show improved outcomes with lower regulatory T-cell levels. CONCLUSIONS Successful immune evasion may reduce T-cell infiltration in HPV infected and precancerous epithelium, while invasive cancers are highly immunogenic, and regulatory T-cell infiltration increases with cervical disease progression. Understanding these factors may have prognostic value and could aid in novel treatment development and clinical guidelines, but published data are highly heterogeneous and leave important gaps to be filled by future studies.

Abstract
The human papillomavirus (HPV) directly infects cervical keratinocytes and interferes with TLR signalling. To shed light on the effect of HPV on upstream receptors, we evaluated TLRs 1–9 gene expression in HPV-negative normal and HPV-positive pre-malignant and malignant ex vivo cervical tissue. Quantitative real-time polymerase chain reaction was performed separately for epithelial and stromal tissue compartments. Differences in gene expression were analyzed by the Jonckheere-Terpstra trend test or the Student's t-test for pairwise comparison. Laser capture microdissection revealed an increase in TLR3 and a decrease in TLR1 mRNA levels in dysplastic and carcinoma epithelium, respectively. In the stroma, a trend of increasing TLR 1, 2, 5, 6, and 9 mRNA levels with disease severity was found. These findings implicate the involvement of TLR3 and TLR1 in early and late cervical carcinogenesis, respectively, suggesting that stromal upregulation of TLRs may play a role in cervical disease progression.

Abstract
Interferons (IFNs) are expressed by many cell types and play a pivotal role in the generation of immune responses against viral infections. IFN-κ, a novel type I IFN, displays a tight tropism for keratinocytes and specific lymphoid populations and exhibits functional similarities with other type I IFNs. The human papillomavirus (HPV), the etiological agent for cervical cancer, infects keratinocytes of the uterine cervix and has been shown to directly inhibit the IFN pathway. We evaluated IFN-κ, -β, and -γ gene expression in HPV-negative normal and HPV-positive pre-malignant and malignant ex vivo cervical tissue covering the entire spectrum of cervical disease. Quantitative real-time polymerase chain reaction and methods previously optimized for detecting low-expressing genes in cervical tissue were used. In contrast to IFN-β and -γ, IFN-κ mRNA prevalence and levels were unexpectedly higher in diseased compared with normal whole cervical tissue with highest levels observed in invasive carcinoma tissue. Strikingly, laser capture microdissection revealed an absence of IFN-κ mRNA in diseased epithelium, whereas stromal IFN-κ was found exclusively in diseased tissue. IFN-γ and IFN-β were likewise found to be upregulated in diseased cervical stroma. Immunofluorescence supports the involvement of monocytes and dendritic cells in the stromal induction of IFNs in diseased tissue. Further, using three-dimensional raft cultures in which the viral life cycle can be mimicked, human keratinocytes transfected with full-length HPV16 displayed a significant decrease in IFN-κ mRNA compared with non-transfected human keratinocytes. Altogether, these findings show that IFN-κ is down-regulated in cervical keratinocytes harboring HPV, which may be a contributing factor in the progression of a cervical lesion.

Abstract
INTRODUCTION Cervical cancer development from a squamous intraepithelial lesion is thought to be favored by an impaired T cell immunity. We evaluated parameters of T cell alterations such as proliferation, cytokine, and CD3zeta expression in peripheral blood and tumor-infiltrating T lymphocytes from women with squamous intraepithelial lesions (SIL) or cervical cancer (CC). RESULTS AND DISCUSSION T cell proliferation and cytokine messenger RNA (mRNA) expression were similar in women with SIL and healthy donors, whereas low T cell proliferation and lower mRNA expression of IL-2, IL-10 and IFN-gamma were observed in women with CC. Moreover, infiltrating cells showed marginal responses. We also found that CD3zeta mRNA expression, whose protein is required for T cell activation, correlated with a decreased proliferation in advanced stages of the disease. CONCLUSION Experiments with T cells from healthy donors in the presence TGF-beta1 or IL-10 suggest that these cytokines have a relevant role in T cell responses during CC progression.

Abstract
PROBLEM Thriving of tumors amidst rich immune infiltrates is an unexplained paradox. METHOD OF STUDY Immune markers on lymphocytic infiltrates in HPV-positive cervicitis, cervical intraepithelial neoplasia III (CIN III), squamous cell carcinoma (SCC) and normal cervices were characterized immunohistochemically. Regulatory T cells were enumerated and phenotypically characterized using antibodies to FOXP3. RESULTS SCCs had higher numbers of CD4 and CD8 cells; infiltrates expressed more CD25, TGFbeta, and IL10 but had significantly lower IL2 compared with cervicitis and CIN III. Expression of CD25 and IL2 correlated well in cervicitis and CIN III but not in SCC. FOXP3 expression was also higher and ratios of CD4/FOXP3 and CD8/FOXP3 were lower in SCC. A fraction of cervicitis, CIN I, CIN II and CIN III had natural (n) regulatory T cells (Tregs); their lesional distribution was predominantly intraepithelial in cervicitis, while in CIN they were also present in the stroma. The proportion of FOXP3(+) CD25(+); FOXP3(+) CD25(-) and TGFbeta(+) CD25(+) in invasive tumors was 17; 19 and 22 respectively. CONCLUSION Cervical tumors are marked by the presence of an immunoregulatory environment, and harbor equal proportions of 'inactive' n Tregs; activated n Tregs; and Tregs operating via TGFbeta. nTregs in cervicitis and CIN may be a potential marker of persistence.

Abstract
Cervical cancer, the second leading cause of cancer deaths in women, is the consequence of high-risk human papillomavirus (HPV) infections. Toward the development of therapeutic vaccines that can induce both innate and adaptive mucosal immune responses, we analyzed intravaginal (ivag) vaccine delivery of live attenuated Salmonella enterica serovar Typhimurium expressing HPV16L1 as a model antigen. Innate immune responses were examined in cervicovaginal tissues by determining gene expression patterns by microarray analysis using nylon membranes imprinted with cDNA fragments coding for inflammation-associated genes. At 24 h, a wide range of genes, including those for chemokines and Th1- and Th2-type cytokine and chemokine receptors were up-regulated in mice ivag immunized with Salmonella compared to control mice. However, the majority of transcripts returned to their steady-state levels 1 week after immunization, suggesting a transient inflammatory response. Indeed, cervicovaginal histology of immunized mice showed a massive, but transient, infiltration of macrophages and neutrophils, while T cells were still increased after 7 days. Ivag immunization also induced humoral and antitumor immune responses, i.e., serum and vaginal anti-HPV16VLP antibody titers similar to those induced by oral immunization, and significant protection in tumor protection experiments using HPV16-expressing C3 tumor cells. These results show that ivag immunization with live attenuated Salmonella expressing HPV16 antigens modulates the local mucosal gene expression pattern into a transient proinflammatory profile, elicits strong systemic and mucosal immunity against HPV16, and confers protection against HPV16 tumor cells subcutaneously implanted in mice. Examination of the efficacy with which ivag HPV16E7E6 Salmonella induces regression of tumors located in cervicovaginal tissue is warranted.

Abstract
In preclinical tumor model and in human cancer, tumor antigen specific T lymphocytes play a key role in the control of tumor development. Nevertheless in numerous cases, the infiltrating tumor T cells do not seem to influence the clinical progression of the tumor. A better phenotypic and functional characterization of T cells in close contact with tumor associated with a comprehensive analysis of tumor evasion mechanism to the host response should lead to an optimization of cancer immunotherapy protocols.

Abstract
Many cancers arise in epithelial mucosa. These mucosal surfaces are characterized by the induction of divergent immune responses, as they are both the main portal of entry for pathogens and a large niche of commensal bacteria and tolerized antigens. In addition, mucosa located in different anatomical sites harbor distinct typical features. Exploiting the different requirements for inducing an effective immune response at mucosal sites might help to define new immunotherapeutic approaches against epithelial cancers, at least in the case of differentiated tumors that have retained their mucosal characteristics.

Abstract
OBJECTIVE The host immune response is essential for restraining both HPV infections and HPV-related cervical cancer. We previously reported a direct correlation between proteolytic activity and malignant progression from precursor lesions to invasive cervical carcinoma. The present study was undertaken to investigate whether proteinases from cervical carcinoma extracts and representative purified proteinases involved in tumor progression could regulate lymphocyte proliferation to phytohemagglutinin (PHA) mitogen. METHODS Extracts were prepared from tissue samples obtained from patients with invasive cervical squamous carcinoma, squamous intra-epithelial lesions or women with normal cervix. Lymphocytes obtained from a single healthy donor were pre-incubated with one of these extracts in the presence or absence of proteinase inhibitors, and stimulated with PHA during 72 h. The proliferative response was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) method (re-validated with thymidine uptake). RESULTS Lymphocyte proliferation was significantly decreased by cervical carcinoma extracts, while only slightly decreased by squamous intra-epithelial lesions or normal extracts. Inhibitor assays indicated that proteinases from cervical carcinoma were responsible for 53.30% of total suppressive activity. We found that purified enzymes such as trypsin, cathepsin B, uPA and type IV collagenase suppressed the proliferative response in a dose-dependent fashion. CONCLUSIONS Our data suggest that in addition to the classic role in tumor invasion, proteases could represent an immune evasion mechanism in cervical carcinoma.

Abstract
The presence of cyanobacterial toxins in drinking and recreational waters represent a potential health hazard to the public. Microcystin-LR (MC-LR) is the most commonly encountered toxin and is a potent cyclic heptapeptide hepatotoxin produced by cyanobacteria. In this study, the immunomodulation by MC-LR of BALB/c mice peritoneal macrophages was investigated in vitro on mRNA levels of induced nitric oxide synthase and multiple cytokines by reverse-transcription polymerase chain reaction (RT-PCR). Lavaged peritoneal macrophages were incubated for 6 h with lipopolysaccharide (LPS) at a concentration of 100 microg/L and MC-LR at doses of 1, 10, 100, and 1000 nmol/L. Total RNA was extracted from the incubated macrophages, and then the levels of mRNA for induced nitric oxide synthase (iNOS), IL-1beta, TNF-alpha, GM-CSF, and IFN-gamma were detected. The results showed that expression of mRNA for iNOS, IL-1beta, TNF-alpha, GM-CSF, and IFN-gamma decreased significantly compared to the positive control (LPS only). These results have led us to propose the need for the establishment of a survey of the immunotoxicity of microcystins.

Abstract
Microcystins (MCs) are the toxic molecules produced by common cyanobacterium in freshwater blooms. Their toxicities have brought severe health issues to livestock and human being. Microcystin-LR (MC-LR) is one of the most toxic MCs. This paper presents the profile of the immunomodulation of MC-LR to BALB/c mice peritoneal macrophages. Macrophages were stimulated with 100microg/l lipopolysaccharide (LPS) and MC-LR at dose of 1, 10, 100, 1000nmol/l, respectively, for 24h. Nitric oxide (NO) production in cell culture supernatants was quantified by using Griess reagent method. Total RNA was extracted from incubated macrophages then the mRNA abundance of induced nitric oxide synthase (iNOS), IL-1beta, TNF-alpha, GM-CSF, IFN-gamma was monitored by using reverse-transcriptional polymerase chain reaction (RT-PCR). The results demonstrated that NO production, mRNA levels of iNOS, IL-1beta, TNF-alpha were down regulated by MC-LR dose-dependently and mRNA levels of GM-CSF and IFN-gamma were also decreased but in dose-independent manner. Our results illustrated the involvement of NO production, iNOS and some cytokines in mice immune system in microcystin shock.
