Muntinga CLP, de Vos van Steenwijk PJ, Bekkers RLM, van Esch EMG. Importance of the Immune Microenvironment in the Spontaneous Regression of Cervical Squamous Intraepithelial Lesions (cSIL) and Implications for Immunotherapy. J Clin Med 2022; 11:jcm11051432. [PMID: 35268523 PMCID: PMC8910829 DOI: 10.3390/jcm11051432] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 02/28/2022] [Accepted: 03/03/2022] [Indexed: 12/10/2022] Open
Abstract
Cervical high-grade squamous intraepithelial lesions (cHSILs) develop as a result of a persistent high-risk human papilloma virus (hrHPV) infection. The natural course of cHSIL is hard to predict, depending on a multitude of viral, clinical, and immunological factors. Local immunity is pivotal in the pathogenesis, spontaneous regression, and progression of cervical dysplasia; however, the underlying mechanisms are unknown. The aim of this review is to outline the changes in the immune microenvironment in spontaneous regression, persistence, and responses to (immuno)therapy. In lesion persistence and progression, the immune microenvironment of cHSIL is characterized by a lack of intraepithelial CD3+, CD4+, and CD8+ T cell infiltrates and Langerhans cells compared to the normal epithelium and by an increased number of CD25+FoxP3+ regulatory T cells (Tregs) and CD163+ M2 macrophages. Spontaneous regression is characterized by low numbers of Tregs, more intraepithelial CD8+ T cells, and a high CD4+/CD25+ T cell ratio. A ‘hot’ immune microenvironment appears to be essential for spontaneous regression of cHSIL. Moreover, immunotherapy, such as imiquimod and therapeutic HPV vaccination, may enhance a preexisting pro-inflammatory immune environment contributing to lesion regression. The preexisting immune composition may reflect the potential for lesion regression, leading to a possible immune biomarker for immunotherapy in cHSILs.

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
Introduction: Human papillomavirus (HPV) are the causative agent of mucosal neoplasia. Both cervical, anal and oropharyngeal cancers incidence is constantly increasing, making the HPV infection, a significant worldwide concern. Together, the CD8+ T cytotoxic cell-mediated response and the HPV-specific antibody response control most of the HPV infections before the development of cancers.Areas covered: We searched the MEDLINE and EMBASE databases and identified 228 eligible studies from 1987 to 2019 which examines both naturally acquired and vaccine induced humoral immunity against HPV infection in female and male subjects from worldwide origin. Herein, we synthesize current knowledge on the features of systemic and mucosal humoral immunity against HPV. We discuss the issues of the balance between the viral clearance or the escape to the host immune response, the differences between natural and vaccine-induced HPV-specific antibodies and their neutralizing capability. We also discuss the protection afforded after natural infection or following prophylactic vaccination.Expert opinion: Understanding the antibody response induced by HPV infection has led to the design of first-generation prophylactic vaccines. Now, prophylactic vaccination induces protective and long-lasting antibody response which would also strengthened the natural moderate humoral response in people previously exposed to the virus.

Abstract
OBJECTIVE To compare the densities of CD1a + immature and CD83+ mature dendritic cells, and inflammatory infiltrate cells between smokers and non-smokers with oral leukoplakia. Parameters associated with malignant transformation were also evaluated. DESIGN 21 smokers and 23 non-smokers diagnosed with oral leukoplakia were obtained. Densities of inflammatory infiltrate cells were calculated in H&E sections. Immunohistochemistry using anti-CD1a and anti-CD83 was performed and densities were calculated. Comparisons and statistical analyses were performed among the groups and parameters as gender, lesion size, site, and presence of cell dysplasia were analyzed. RESULTS A lower density of CD83+ cells was observed in smokers compared to non-smokers (P < 0.05). For samples of smokers, a lower density of CD1a + cells, CD83+ cells, and inflammatory infiltrate cells was observed in samples with <10 mm compared to samples ≥10 mm of diameter (P < 0.05), and a lower density of CD83+ cells was also observed between samples without dysplasia compared to samples with dysplasia (P < 0.05). CONCLUSION In oral leukoplakia samples, dendritic cell density decreases in the presence of smoking habit, and increases in larger lesions and with epithelial dysplasia. Smoking habit is an external factor that contribute to alteration of the anti-tumoral immune defense system in lesions of oral leucoplakia, reinforcing that smoking elimination is important to control the development of this disease.

Abstract
The marked depletion of dendritic cells (DCs) in skin cancers, as well as preneoplastic and neoplastic cervical epithelium, suggests a central role for DCs in productive human papillomavirus (HPV) infection and cancer promotion. It has been suggested that HPV may facilitate tumor development by reducing DC density, contributing to a decrease in local immune surveillance. In this study, we have examined the response of human DCs transfected with a construct containing the HPV18 genome and their subsequent expression of papilloma virus proteins. Transfected cells expressed the L1 major capsid protein and upregulated E6 and E7 oncoprotein transcripts as detected by RT-PCR. Transfection of DCs also resulted in a significant increase in cytokine production. Finally, we observed that HPV18 transfection decreased the migratory activity of DCs. Our data indicate that HPV transfection of DCs leads to changes in migratory activity and cytokine production, which potentially can suppress or delay immune responses to viral antigens. Additionally, changes in cytokine production by HPV-transformed human fibroblasts and human cervical epithelial cells revealed that the migratory and antigen-presenting functions of DCs may be impaired by the suppressive effects of cytokines produced by HPV-infected epithelial and stromal cells.

Abstract
High-risk human papillomaviruses (HPVs) cause a variety of malignancies of the mucosal epithelium. However, the local immune evasion strategies used by HPV-transformed cells remain unclear. Here, we examined the effect of HPV-positive cancer cells on human peripheral blood monocytes, which are precursors of Langerhans cells, key antigen-presenting cells in the squamous epithelium. HPV-positive cervical cancer cells and HPV-E6 expressing cells inhibited monocyte differentiation to Langerhans cells in a contact-dependent manner. Unlike Langerhans cells, monocytes that differentiated in the presence of HPV16 E6-expressing cells exhibited high levels of endocytic activity. Our results suggest that cells infected by high-risk HPV evade immune surveillance by blocking the differentiation of monocytes into competent antigen presenting cells.

Abstract
A common feature shared between several human cancer-associated viruses, such as Epstein-Barr virus, Hepatitis B virus and Hepatitis C virus, and Human papillomavirus (HPV) is the ability to reduce the expression of cellular E-cadherin. Since E-cadherin is used by Langerhans cells to move through the stratified epithelium, its reduction may affect the efficiency by which the immune system responds to HPV infection and the length of persistent HPV infections. We observed that the E7 protein of this virus (HPV16) is most efficient at reducing E-cadherin levels. This E7 activity is independent of retinoblastoma protein or AP-2α degradation. Instead it is associated with augmentation of cellular DNA methyltransferase I (Dnmt1) activity. Significantly, inhibition of Dnmt activity re-established E-cadherin levels of the cells, presenting the possibility that similar epigenetic intervention clinically may be a way to re-establish the influx of Langerhans cells into infected epithelium to counteract HPV persistence.

Abstract
Human papillomavirus (HPV) infection, particularly type 16, is causally associated with cancer of the uterine cervix. The persistence or progression of cervical lesions suggests that viral antigens are not adequately presented to the immune system. This hypothesis is reinforced by the observation that most squamous intraepithelial lesions (SILs) show quantitative and functional alterations of Langerhans cells (LC). The infiltration of immature LC in the squamous epithelium is mainly controlled by Macrophage Inflammatory Protein 3alpha/CCL20. After having shown that CCL20 production is altered in HPV-transformed keratinocytes (KC), the possible role of HPV16 E6 and E7 viral oncoproteins in the reduced CCL20 levels observed in SILs was investigated by silencing HPV16 E6 and E7 oncogenes by RNA interference (siRNA). This treatment not only increased CCL20 secretion but also resulted in the modulation of NF-kappaB p50, p52 and p65 precursor localization. Moreover, silencing of E6 and E7 oncogenes in HPV16-transformed KC induced a significantly higher migratory capacity of LC in a Boyden chamber assay and in an in vitro formed (pre)neoplastic epithelium reminiscent of high-grade SILs. Anti-CCL20 neutralizing antibody experiments showed that the increased migration of LC is due to the re-expression of CCL20 in E6 and E7 siRNA transfected KC. These data suggest that HPV16 E6/E7-induced down-regulation of CCL20 observed during the cervical carcinogenesis may contribute to a diminished capacity of the immune system to control HPV infection.

Abstract
BACKGROUND HIV-positive patients have unpredictable local immune responses even with severe systemic immunosuppression and data reported to date is insufficient to predict the effect of imiquimod in HIV-positive patients. OBJECTIVE To evaluate the efficacy of 5% topical imiquimod in HIV-positive male patients with anogenital warts (AGW) and to elucidate its effect on recurrence. STUDY DESIGN Open-label clinical trial. RESULTS Of the 43 patients enrolled, 86% completed treatment. Patients' mean age was 34 years (range: 19-50). Thirty-one patients were receiving highly active antiretroviral therapy (HAART) therapy. At week 16, 10 patients completely cleared lesions and 21 patients had a wart size reduction > or =50%. At 20 weeks of therapy, 17 patients achieved total clearance whereas 14 patients had a >50% wart reduction. Clearance was not influenced by CD4-counts, HIV-viral load, previous therapy, or wart localization. Of the patients who experienced a complete clearance, five (29%) had a recurrence. Mean time of recurrence was 14.4 weeks. Erythema, pruritus, and burning sensation were the most frequent local skin reactions. CONCLUSIONS Topical 5% imiquimod is safe and may benefit HIV-positive patients with anogenital warts particularly when it is used for up to 20 weeks. It is also useful to decrease wart recurrence.

Abstract
Cervical cancer is the second most frequent gynecological malignancy in the world. Human papillomavirus (HPV) infection is the primary etiologic agent of cervical cancer. However, HPV alone is not sufficient for tumor progression. The clinical manifestation of HPV infection depends also on the host's immune status. Both innate and adaptive immunity play a role in controlling HPV infection. In untransformed HPV-infected keratinocytes, the innate immunity is induced to eliminate the invading HPV pathogen through sensitization to HPV-related proteins by epithelial-residing Langerhans cells (LCs), macrophages, and other immune cells. Once the HPV infection escapes from initial patrolling by innate immunity, cellular immunity becomes in charge of killing the HPV-infected keratinocytes of the uterine cervix through systemic immune response developing by dendritic cells (DCs) in the regional lymphoid organs or through local immune response developing by LCs in the cervix. Thereby, DC/LC plays a critical role in eliciting innate and adaptive cellular immune responses against HPV infection. HPV-associated cervical malignancies might be prevented or treated by induction of the appropriate virus-specific immune responses in patients. Encouraging results from experimental vaccination systems in animal models have led to several prophylactic and therapeutic vaccine clinical trials.

Abstract
Infection with high-risk human papillomavirus (HPV) types, particularly types 16 and 18, contributes to 90% of cervical cancer cases. HPV infects cutaneous or mucosal epithelium, tissue that is monitored for microbial infection or damage by Langerhans cells. In lesions produced by HPV type 16, there is a reduction in numbers of immune cells, especially Langerhans cells. Langerhans precursor cells selectively express CCR6, the receptor for macrophage inflammatory protein 3alpha (MIP-3alpha), and function as potent immune responders to inflamed epithelium and initiators of the innate immune response. It has been reported that E6 and E7 of high-risk HPVs interfere with immune mediators in order to suppress the recruitment of immune cells and antiviral activities of infected cells. Here we show that, following proinflammatory stimulus, HPV-16 E6 and E7 inhibit MIP-3alpha transcription, resulting in suppression of the migration of immature Langerhans precursor-like cells. Interestingly, the E6 and E7 proteins from the low-risk HPV types also inhibited MIP-3alpha transcription. These results suggest that one mechanism by which HPV-infected cells suppress the immune response may be through the inhibition of a vital alert signal, thus contributing to the persistence of HPV infection.

Abstract
The aim of this study was to characterize the immune system profile in the uterine cervix of 17 human papillomavirus (HPV)-infected women, compared with 17 whom were coinfected with HIV-1. Five histologically normal cervices in immunocompetent women were used as controls. HPV infection was associated with a marked increase in cells expressing interleukin (IL)-6, interferon gamma (IFN-gamma), and tumor necrosis factor alpha (TNF-alpha). Coinfection by HPV and HIV-1 led to decreased expression of IL-6, TNF-alpha, and IFN-gamma. However, coinfection led to increased numbers of cells expressing IL-4, IL-10, and IL-8. Compared with the histologically normal cervices, increased numbers of macrophages (CD68, RFD7) and T lymphocytes (CD4, CD8) were seen in HPV-infected cervices; coinfection with HIV-1 was associated with a higher number of CD8 cells and lower number of CD68 cells. HPV DNA localized exclusively to the dysplastic squamous cells, whereas HIV-1 RNA was detected mainly in CD68-positive stromal cells. In conclusion, this study shows differential expression of various cytokines and classes of inflammatory cells, relative to HIV-1 infection and HPV coinfection, which may relate to the risk of transmission of HIV-1 and increased risk of cervical cancer in these women.

Abstract
Human immunodeficiency virus (HIV-1) has become an important risk factor for human papillomavirus (HPV) infection and the development of HPV associated lesions in the female genital tract. HIV-1 may also increase the oncogenicity of high risk HPV types and the activation of low risk types. The Center for Disease Control and Prevention declared invasive cervical cancer an acquired immunodeficiency virus (AIDS) defining illness in HIV positive women. Furthermore, cervical cancer happens to be the second most common female cancer worldwide. The host's local immune response plays a critical factor in controlling these conditions, as well as in changes in the number of professional antigen-presenting cells, cytokine, and MHC molecules expression. Also, the production of cytokines may determine which arm of the immune response will be stimulated and may influence the magnitude of immune protection. Although there are many studies describing the inflammatory response in HPV infection, few data are available to demonstrate the influence of the HIV infection and several questions regarding the cervical immune response are still unknown. In this review we present a brief account of the current understanding of HIV/HPV co-infection, emphasizing cervical immune response.

Abstract
To examine the possible association between cervical cancer and Lymphotoxin-alpha (LT(alpha)) polymorphisms, C804A and A252G, an incident case-control study was conducted in Japanese. The cases were 131 cervical cancer patients. Controls were 320 healthy women. Risk estimation was conducted by an unconditional logistic model. Complete linkage disequilibrium was seen between LT(alpha) C804A and LT(alpha) A252G. We found that, compared with the 804CC genotype, 804CA and 804AA were associated with a decreased risk of cervical cancer (OR = 0.64, 95% CI = 0.40-1.02; and OR = 0.45, 95% CI = 0.21-0.95, respectively), especially of SCC (OR = 0.54, 95% CI = 0.32-0.91; and OR = 0.39, 95% CI = 0.16-0.92, respectively).

Abstract
Although human papillomavirus (HPV) DNA is detected in the majority of squamous intraepithelial lesions (SILs) and squamous cell carcinomas (SCCs) of the uterine cervix, the persistence and progression of cervical lesions suggest that viral antigens are not adequately presented to the immune system. This hypothesis is reinforced by the observation that most SILs show quantitative and functional alterations of Langerhans cells (LCs). The aim of this study was to determine whether modulation of E-cadherin-mediated homophilic and heterotypic interactions between keratinocytes and LCs is involved in these abnormalities of LCs in (pre)neoplastic cervical epithelium. Cell membrane expression of E-cadherin and the density of CD1a+ LCs were low in the epithelium of SILs and SCC biopsy specimens, compared with normal exocervical epithelium. Dendritic cells (DCs) and LCs generated in vitro were randomly distributed throughout the full thickness of organotypic cultures of E-cadherin- HPV-transformed cells. In contrast, these cells rapidly adhered to the keratinocyte cell layers when HPV-transformed cells transfected with E-cadherin were used. These data suggest that the E-cadherin-mediated contact between keratinocytes and LCs is potentially important for initiating or maintaining the immune response during chronic HPV infection.

Abstract
The design of the human papillomavirus (HPV) infection cycle is tightly fitted to the differentiation program of its natural host, the keratinocyte. This has important consequences for the role of antigen-presenting cells in the priming of antiviral immunity. The confinement of HPV infection to epithelia puts the epithelial dendritic cell, the Langerhans cell (LC), in charge of the induction of T cell-dependent immunity. Because HPV-infected keratinocytes cannot reach the regional lymphoid organs, and HPV-infection of LCs does not result in viral gene expression, priming of antiviral T cells exclusively depends on cross-presentation of viral antigens by the LC. Sensitization of the immune system in the regional lymphoid organs elicits systemic anti-HPV immunity as well as intraepithelial immune surveillance by memory-type intraepithelial T cells and locally produced antibodies. The high rate of spontaneous rejections of high-risk HPV-infections and HPV-positive premalignant lesions indicates that in general the LC-driven antigen presentation machinery is capable of raising an effective immune defense against HPV. Epidemiological studies also reveal that a decrease in the vigilance of the immune system is readily exploited by HPV to escape immune destruction, resulting in persistent infections and development of HPV-positive cancers. In view of the inherent antigenicity of HPV, immune intervention strategies constitute a promising approach for both the prevention and the therapeutic treatment of HPV-induced diseases. Importantly, the mechanisms that govern the induction and effector phases of the intraepithelial immune surveillance against HPV must be taken into account when designing such strategies.

Abstract
This study investigates local alterations in T-cell and macrophage subsets that occur in cervical epithelial neoplasia (CIN), in the presence and absence of human immunodeficiency virus (HIV) infection. Ectocervical biopsies from 10 women with CIN who were infected with HIV, and 10 women with CIN but no HIV infection were studied by immunocytochemistry. Significantly increased proportions of activated CD8+ T cells were seen in all CIN biopsies, and these proportions were further increased in the presence of HIV infection. Levels of CD8+TIA-1+ cells were particularly increased in the CIN+HIV+ group. There was a lack of expression of CD28 on the CD8+ cells of the epithelium of CIN+HIV+ samples. A significant reduction in the proportion of epithelial inductive D1+ macrophages and an increase in D1+D7+-suppressive cells were observed in the CIN+HIV+ cohort. The lack of expression of CD28 on the CD8+ cells of the epithelium of CIN+HIV+ samples in combination with the reduced CD4+ T-cell numbers seen in the presence of HIV infection may contribute to the development of higher grade CIN in this susceptible group. This may be aggravated by the reduction in the D1+ epithelial inductive macrophages, which might reflect recruitment of more suppressive D1+D7+ cells. This would further compromise the ability of the local T-cell system to respond to antigens and thus contribute to the development of neoplasia at this site. These results suggest that the increase in activated CD8+ T cells is a consequence rather than a cause of CIN.

Abstract
Clinical and experimental data demonstrate that local cytokines are able to induce tumor regression and in some cases antitumor systemic immune response. IRX-2 is a cell-free mixture of cytokines obtained from unrelated donor lymphocytes with demonstrated ability to induce immune mediated regression of squamous cell carcinomas of head and neck. The objective of this study was to evaluate the antitumor activity and toxicity of IRX-2 in untreated early stage cervical cancer patients. Ten consecutive patients clinically staged IB1, IB2 and IIA were treated with a neoadjuvant immunotherapy regimen that consisted in a single IV dose of cyclophosphamide at 300 mg/m2 on day 1, oral indomethacin or ibuprofen and zinc sulfate were administered from days I to 21 and 10 regional perilymphatic injections of IRX-2 on days 3 to 14. All patients were scheduled for radical hysterectomy on day 21. The clinical and pathological responses, toxicity and survival were evaluated. Clinical response was seen in 50% of patients (three partial responses, two minor responses). Seven patients underwent surgery and pathological tumor reduction associated with tumor fragmentation was found in five cases. Histological studies demonstrated a rather heterogeneous cell type infiltrating pattern in the tumor which included lymphocytes, plasma cells, neutrophils, macrophages and eosinophils. Immunohistochemical analysis of the surgical specimens demonstrated an increase of tumor infiltrating CD8+ cells. The treatment was well tolerated except for mild pain and minor bleeding during injections and gastric intolerance to indomethacin. At 31 months of maximum follow-up (median 29), eight patients are disease-free. Our results suggest that the immunotherapy approach used induces tumor responses in cervical cancer patients. Further studies are needed to confirm these results as well as to elucidate the mechanisms underlying these effects.

Abstract
In the present study we show that malignant human papillomavirus (HPV)-positive cells lost their ability to synthesize endogenous beta interferon (IFN-beta) upon tumor necrosis factor alpha (TNF-alpha) treatment. IFN-beta transcription, however, was reinducible in nonmalignant HPV-positive cells, which was confirmed in functional protection assays against encephalomyocarditis virus or vesicular stomatitis virus infections. Addition of neutralizing antibodies against IFN-beta blocked the antiviral effect, excluding the possibility that other IFN types were involved. Conversely, both malignant and immortalized cells could be protected against viral cytolysis when either IFN-beta, IFN-alpha, or IFN-gamma was added exogenously. This indicates that only the cross talk between TNF-alpha and the IFN-beta pathways, and not IFN-alpha/beta and IFN-gamma signaling in general, is perturbed in cervical carcinoma cells. Notably, full virus protection was restricted exclusively to nonmalignant cells, indicating that the antiviral effect correlates with the growth-inhibitory and virus-suppressive properties of TNF-alpha. The IFN-regulatory factors IRF-1 and p48 (ISGF3gamma) emerged as key regulatory molecules in the differential IFN-beta response, since their transcription was either absent or only inefficiently enhanced in tumorigenic cells upon treatment with TNF-alpha. Inducibility of both genes, however, became reestablished in cervical carcinoma cells, which were complemented to nontumorigenicity after somatic cell hybridization. Complementation was paralleled by the entire reconstitution of cytokine-mediated IFN-beta expression and the ability of TNF-alpha to exert an antiviral state. In contrast, under conditions where tumor suppression was not accomplished upon somatic cell hybridization, neither expression of IRF-1, p48, and IFN-beta nor antiviral activity could be restored.

Abstract
Although human papillomavirus (HPV) antigens are expressed in a majority of (pre)neoplastic lesions (squamous intraepithelial lesions; SILs) of the uterine cervix, progression to invasive cancer may occur, which suggests that the presentation of viral antigens to the immune system is deficient in some SILs. To determine whether professional antigen-presenting cells die in SILs, we assayed for the apoptosis of immature dendritic cells (DC) in organotypic cultures of HPV-transformed keratinocytes, which reproduce many features of in vivo observed SILs. Unexpectedly, the infiltration of organotypic cultures by DC specifically induced the apoptosis of HPV+ tumor cells, whereas DC were not affected. In the same conditions and in coculture experiments, apoptosis was not observed in normal keratinocytes. The induction of apoptosis required membrane contacts between DC and HPV-transformed keratinocytes. Although the HPV+cell lines were sensitive to the effects of TRAIL, soluble TRAILR2-Fc did not block the DC-induced apoptosis. Furthermore, although FasL and Fas were detected on DC and HPV+ cell lines, respectively, functional analysis revealed that this pathway is not responsible for the apoptosis induced by the DC. All together these results suggest that DC may be at the interface between innate and adaptive immunity by inducing the apoptosis of (pre)neoplastic cells.

Abstract
AIMS The infiltration of Langerhans cells in adenocarcinomas and squamous cell carcinomas of the lung was examined in relation to prognostic implications and human papillomavirus (HPV) infection. METHODS AND RESULTS Samples from 62 adenocarcinoma and 59 squamous cell carcinoma patients in 1995-97, the prognosis of which had been followed up, were used. The Langerhans cells were demonstrated immunohistochemically using anti S100a and CD1 antibodies. Human papillomavirus (HPV) infection was examined by polymerase chain reaction (PCR) and nonisotopic in-situ hybridization (NISH) methods. Statistical analysis was carried out using the Kaplan-Meier method (Wilcoxon analysis) and multiple regression analysis. HPV infection was demonstrated in 12 cases (19.4%) of adenocarcinoma. The HPV-infected adenocarcinomas had abundant faintly eosinophilic cytoplasm, and were immunohistochemically positive for the surfactant apoprotein A. In the 59 cases of squamous cell carcinomas 19 were of the well differentiated form, and 29 and 11 were moderately and poorly differentiated cases, respectively. HPV was detected in 29 cases (49.2%) (13 well and 16 moderately differentiated cases). In all HPV-infected adenocarcinoma and squamous cell carcinoma cases, extremely large numbers of Langerhans cells (more than 100 per high-power field) were demonstrated in the tumour nests. In contrast, in the non-HPV-infected adenocarcinomas and squamous cell carcinomas, only a few (less than about 10 per high-power field) Langerhans cells were observed. The squamous cell carcinoma cases with high Langerhans cell infiltration, which were also infected with HPV, showed a significantly good prognosis (P = 0.007). The adenocarcinoma cases with high Langerhans cell infiltration tended to have a better prognosis than the cases with low Langerhans cell infiltration, but the difference was not statistically significant. The low number of highly infiltrated cases was insufficient for an adequate statistical analysis. Furthermore, there was no significant correlation between either Langerhans cell infiltration and smoking, or HPV infection and smoking, in either squamous cell carcinoma or adenocarcinoma cases. CONCLUSIONS It was considered that the extremely high Langerhans cell infiltration in the tumours was caused by HPV infection. The extremely large number of Langerhans cells in the tumours contributes to the favourable prognosis for HPV-infected lung cancer.

Abstract
The purpose of this study is to develop a reliable in vitro human model to test new immunotherapeutic approaches for squamous cell carcinoma that develop on mucosal surfaces. The organotypic (raft) culture permits cells to proliferate and differentiate at an air-liquid interface on a dermal equivalent support. Normal keratinocytes stratify and fully differentiate in a manner similar to the normal squamous epithelial tissues, while human papillomavirus-immortalized and established squamous carcinoma cell lines exhibit dysplastic morphologies similar to (pre)neoplastic lesions seen in vivo. We have demonstrated the ability of these organotypic cultures to be manipulated by altering the epithelial stratification with cytokines (interferon-gamma and tumor necrosis factor-alpha) and by integrating activated lymphocytes or dendritic cells into the in vitro formed epithelial sheet. This model may provide a useful tool to investigate the factors contributing to the presence and function of immunocompetent cells within a neoplastic epithelium that develops on a mucosal surface.

Abstract
Human papillomavirus (HPV) infections are known to play an important role in the pathogenesis of cervical neoplasia. Considering the morbidity and mortality of cervical cancer, infection with HPV can be regarded as a worldwide problem, especially in developing countries. Currently, many studies focus on the development of both prophylactic and therapeutic HPV vaccines. Crucial for these vaccination protocols to be successful is that they will result in a long-lasting ability to generate an immune response that will eliminate the virus. HPV transmission and subsequent infection is a local event in the lower female genital tract and therefore the efficacy of vaccines against this locally transmitted infection can be best assessed by parameters of local immunity. In this review we describe both the epidemiology of HPV-related cervical neoplasia and the general aspects of mucosal immunity in the female genital tract while focusing on the local humoral immunity in HPV-related cervical neoplasia.

Abstract
On the subtropical island of Okinawa, squamous cell carcinoma (SCC), particularly the well-differentiated form, is the most frequent type of lung cancer, while this form is relatively rare on the Japanese mainland and in other countries. Furthermore, in Okinawa, in 1993, 80% of SCC cases of the lung were found to be infected with human papillomavirus (HPV). We studied the prognosis of SCC of the lung with HPV infection (n = 25) and compared it with non-HPV-infected SCC (n = 16). Using the Kaplan-Meier method (Wilcoxon analysis), the prognosis of HPV-infected cases was found to be better than that of the non-infected cases. In the virus-infected cases, apoptosis and infiltration of a large number of Langerhans cells were demonstrated. In addition to these findings, the virus-infected tumors were demonstrated to be histologically well-differentiated, perhaps contributing to the favorable prognosis. However, among the virus-infected cases, the type 16 virus-infected cases showed a poorer prognosis, compared to those infected with other HPV types. p53 gene mutation was also examined, and was considered to be an unfavorable prognostic factor, as reported elsewhere. However, in Okinawa, HPV-positive cases with p53 mutations showed a slightly better prognosis than did non-viral infected cases with p53 mutations. The TNM staging system was also useful for categorizing the virus-infected cases. The prognosis of stage III (A and B) cases was poor. All of our present cases received surgical treatment. Chemotherapy and radiation therapy were not performed. Such treatment, however, might be effective, because virus-infected uterine cervical carcinomas have been routinely treated with chemotherapy and radiation. Furthermore, if the immunological basis of increased Langerhans cell infiltration in HPV-infected cases is elucidated, a clinical trial with immunotherapy may be favorable for the clinical outcome.

Abstract
The purpose of this study was to investigate the ability of CD1a+ Langerhans/dendritic cells (LCs/DCs) to infiltrate human papillomavirus (HPV)-associated (pre)neoplastic lesions of the uterine cervix. Migration of LCs/DCs in the presence of keratinocytes derived from normal cervix and HPV-transformed cell lines was evaluated in Boyden chambers and in organotypic cultures and correlated with granulocyte/macrophage colony-stimulating factor (GM-CSF) production by the cells, as determined by ELISA. Conditioned media of HPV-transformed keratinocytes contained lower amounts of GM-CSF and induced a decreased motile response of LCs/DCs in the Boyden chamber assay compared with those of normal cervical keratinocytes. The migration of LCs/DCs in the presence of conditioned media from normal keratinocytes could be blocked by an anti-GM-CSF antibody, and the migration of LCs/DCs in the presence of conditioned media from HPV-transformed keratinocytes could be increased by supplementing the media with recombinant GM-CSF. GM-CSF was also a potent factor in enhancing the colonization of LCs/DCs into organotypic cultures of HPV-transformed keratinocytes, as the infiltration of LCs/DCs in the in vitro-formed (pre)neoplastic epithelium was minimal under basal conditions and dramatically increased after the addition of GM-CSF to the cultures. These results suggest that GM-CSF could play an important role in the recruitment of LCs/DCs into the HPV-transformed (pre)neoplastic cervical epithelium and be useful as a new immunotherapeutic approach for cervical (pre)cancers.

Intraepithelial T-lymphocyte and Langerhans' cell densities and their distribution are not influenced by the menstrual cycle and are the same in both ectocervix and transformation zone. CONCLUSION The wide variation of T lymphocyte subpopulations and Langerhans' cell densities in the normal epithelium of the uterine cervix is stressed. We are the first to present a large and well-defined control series, which is indispensable to study the effect of smoking and other factors on the cervical immune system.

Abstract
This study addressed the notion that the progression of cervical cancer is associated with a T-helper 2 (TH2) immunodeviation by analysing cytokine expression in 60 cervical biopsy specimens, spanning the spectrum from normal cervical tissue to high-grade squamous intraepithelial lesions (SILs). The biopsies were analysed by immunohistochemistry for the expression of TH1 [interleukin-2 (IL2), interferon gamma (IFN gamma)] and of TH2-type cytokines (IL4, IL6). Positive cells were usually observed in the subepithelial connective tissue, where most CD4+ cells were also detected. The density of IL2+ cells was significantly lower in high-grade SILs than in normal tissues taken either from the ectocervix or from the transformation zone. In contrast, significantly higher densities of IL4+ cells and, to a lesser degree, IL6+ cells were found in SIL biopsies compared with histologically normal tissues taken from the adjacent ectocervical region. A significantly higher IL4+/CD4+ cell ratio was also found in high-grade SILs (82 per cent) than in normal cervical biopsies taken from the transformation zone of healthy women showing squamous metaplasia (27 per cent). The elevated density of TH2+ cells in SIL biopsies was associated with both the expression of HLA-DR by keratinocytes and a diminished number of intraepithelial Langerhans' cells (CD1a+). In conclusion, the increased TH2+/CD4+ cell ratio in SIL biopsies suggest the presence, during cervical carcinogenesis, of a TH2 immunodeviation that could participate in the immunoescape of preneoplastic cervical keratinocytes.

Abstract
Leukocytic infiltrates are a morphologic feature of most solid tumors, including uterine cervical intraepithelial neoplasia (CIN) and invasive carcinoma. We have studied 50 cases of CIN I, CIN II, CIN III, invasive carcinoma and normal controls in order to evaluate the inflammatory response. Two markers--CD68, a macrophage-specific marker, and ICAM-1, present on leukocytes, blood vessels and epithelial cells--were employed. Results have demonstrated similar inflammatory cell counts in normal, CIN II and CIN III lesions by both markers, and lower counts for CIN I. Invasive carcinomas demonstrated a statistically significant increase in infiltrate density by both CD68 (p < 0.002) and ICAM-1 (p < 0.05). Macrophage density by either marker did not correlate with Human Papillomavirus (HPV) presence, specific type, or evidence of co-infection with several types. We conclude that the inflammatory response to cervical intraepithelial-neoplasia is inadequate. The elevated cell counts in invasive carcinomas may reflect a reaction towards invasion rather than tumor-specific immune response. Depression of inflammation in CIN I lesions may be associated with active viral replication in these lesions.

Abstract
BACKGROUND Mechanisms whereby cells infected with human papillomavirus (HPV) escape immune surveillance, ultimately leading to invasive cervical carcinoma, may involve changes in local cytokine production, loss of responsiveness to cytokines, and alterations in the expression of immune-regulatory molecules such as histocompatibility-related leukocyte antigen (HLA) Class 1 and 2 and ICAM-I. This study examined the separate and combined effects of immune-activating cytokines, interferon (IFN)-gamma, IFN-beta, and tumor necrosis factor (TNF)-alpha, on the expression of these molecules. METHODS Membrane protein expression and cellular mRNA levels were analyzed in cervical carcinoma-derived cell lines, SiHa and CaSki (with low and high HPV16 copy number, respectively), after exposure to cytokines. RESULTS Both cell lines demonstrated constitutive expression of HLA Class 1 but not HLA Class 2 membrane antigens. IFN-gamma and -beta induced changes in Class 1 mRNA levels but not in membrane molecule expression. IFN-gamma induced dose-dependent expression of Class 2 membrane and mRNA molecules in both cell lines (more pronounced in SiHa than in CaSki cells), which was antagonized by IFN-beta. Constitutive ICAM-I membrane expression was observed only on CaSki cells, although ICAM-I mRNA was expressed in both cell lines. IFN-gamma up-regulated the membrane expression of this molecule, whereas IFN-beta led to its suppression. Differential modulation of ICAM-I mRNA was observed in both cell lines. A lack of response to TNF-alpha was observed throughout the experiments. CONCLUSIONS The findings of this study point to possible mechanisms leading to suppression of local immune response in the pathogenesis of HPV-associated neoplasia. They also emphasize the complexity of developing an efficient cytokine therapy for patients with premalignant cervical disease.

Abstract
In various tumor types dentritic cell, infiltration and the presence of tumor-infiltrating lymphocytes have been associated with an improved clinical outcome. In the uterine cervix these immunocompetent cells have been associated with improved prognosis in high stage disease. The current study examines the significance of stromal and tumor T-lymphocyte infiltration together with S-100 positive dendritic cell infiltration in a series of 73 women with low stage (FIGO 1b) invasive squamous and adenosquamous cervical carcinoma. Thirty four percent of cases contained S-100 positive dendritic cells. These were under-represented in cases showing pelvic recurrence or distant disease (1 of 11 compared to 24 of 62 free of recurrence, P = 0.05) and over-represented in cases showing lymphatic/capillary space involvement (12 of 23 compared to 13 of 46 without vascular space invasion, P = 0.05). The women were followed up for an average of 5.2 years and the five-year survival for women whose tumors contained S-100 positive dendritic cells was 92% compared to 73% for negative cases (P = 0.04). There was a significant association between a low density of tumor infiltrating T-cells and risk of pelvic lymph node spread and subsequent local or distant disease control failure (P = 0.008). A five year survival advantage was seen with five or more CD 3 positive tumor infiltrating T-lymphocytes per high power field (90%) compared to a lower count (68%) (P = 0.04). A similar advantage could not be demonstrated for a high stromal infiltrate of T-cells. As yet neither the specific mechanisms that induce these cells to infiltrate some cervical carcinomas nor the nature of the immunological injury that the cells co-ordinate in tumor tissue are well understood.

Abstract
BACKGROUND AND OBJECTIVES Anogenital warts are caused by human papillomaviruses (HPVs), which should induce cellular immune responses in immunocompetent patients. However, the natural history of these warts shows considerable variation between persons, ranging from spontaneous regression to prolonged persistence. In addition, the efficiency of immunologically based modalities for the therapy of anogenital warts, such as interferon (IFN) treatment, is highly variable. METHODS Considering that preexisting conditions of the host are important factors in an appropriate immune response, the authors determined the pretreatment status of local cell-mediated immune response to HPV infection by reverse transcription-polymerase chain reaction in patients with condyloma acuminatum, who later received IFN treatment and responded well or poorly to that therapy. RESULTS AND CONCLUSIONS The authors found that biopsies from nonresponders were depleted markedly in Langerhans cells, leading to decreases in major histocompatibility complex class II expression and, therefore, to diminished attraction of CD4+ T cells. An inappropriate major histocompatibility complex class I expression also was observed in those nonresponders with decreased CD8+ levels. The mRNA levels of cytokines (interleukin-1a, interleukin-1b, granulocyte-macrophage-colony stimulating factor, tumor necrosis factor that participate in immune responses were low in nonresponders. In contrast, responders demonstrated high macrophage-natural killer cell (CD16-positive) and activated CD4 (IL-2, interferon gamma-positive, TH1 cells) T-cell recruitment against HPV-infected keratinocytes, which is consistent with a delayed-type hypersensitivity-like cellular immune response. Lack of immune response in nonresponders appeared to correlate with high expression levels of the HPV E7 gene. These differences in local cellular immunity might determine the response rate of HPV-infected cells to immunomodulatory therapies.

Abstract
To investigate the effect of tumor-associated macrophages on the in vivo growth properties of cervical carcinoma cells, tumorigenic human papilloma virus (HPV) 18-positive HeLa cells were transfected with an expression vector harboring the cDNA for the macrophage chemoattractant protein-1 JE (MCP-1). Although the endogenous gene is present and not structurally rearranged, its expression seems to be negatively affected by a still unknown mechanism. Inoculation of JE (MCP-1)-negative HeLa cells into nude mice led to rapidly growing tumors, where macrophage infiltration into the inner tumor mass was not detectable immunohistochemically. The activity that attracted mononuclear cells under both in vitro and in vivo condition was reconstituted in HeLa cells after transfection with the JE (MCP-1) expression vector. Heterotransplantation of those cells into immunocompromised animals resulted in significant growth retardation that was accompanied by a strong infiltration of macrophages. On the other hand, in vivo selection of nonmalignant hybrids made between wild-type HeLa cells and normal human fibroblasts in nude mice resulted in tumorigenic segregants 4 mo after inoculation into the animals. Monitoring JE (MCP-1) expression directly within those nodules, we found that transcription was either absent or only weakly detectable. Recultivation of JE (MCP-1)-positive tissue grafts under in vitro conditions revealed that the gene was only marginally inducible by tumor necrosis factor-alpha, a cytokine that normally induces a very strong activation of transcription in nontumorigenic cells. These findings suggest that functional JE (MCP-1) expression and in turn activated macrophages may play a pivotal role in controlling the proliferation rate of HPV-positive cells in vivo.

Abstract
BACKGROUND Cervical intraepithelial neoplasia (CIN) is associated with changes in local immune cell populations, although the role of vascular adhesion molecules in mediating such changes by controlling the traffic of mononuclear cells to the cervix has not been investigated previously. METHODS The authors used immunohistochemistry to examine the expression of three vascular adhesion molecules--ICAM-1, VCAM-1 and E-selectin--in the normal cervix and in biopsies of CIN Grade 1 (CIN-1) (low grade squamous intraepithelial lesions [LG-SIL]) and CIN-2/3 (high grade squamous intraepithelial lesions[HG-SIL]). In addition, the authors examined the functional role of these molecules by adapting the frozen section adhesion assay of Stamper and Woodruff to investigate in vitro the molecular basis of the interaction between cervical endothelial cells and activated T-lymphocytes. RESULTS Whereas there was no difference in adhesion molecule expression between normal cervix and CIN-1 (LG-SIL), all three molecules investigated were significantly up-regulated in CIN-2/3 (HG-SIL), an observation that correlated with an enhanced ability of stromal endothelial cells in CIN-2/3 (HG-SIL) biopsies to bind activated peripheral blood lymphocytes in vitro. Monoclonal antibodies blocking ICAM-1 function were able to reduce such adhesion significantly in three of three experiments, and antibodies blocking VCAM-1 produced a significant reduction in one of three experiments. No inhibition was seen with antibodies against E-selectin. CONCLUSIONS The enhanced expression of vascular adhesion molecules in CIN-2/3 (HG-SIL) appears to be functionally important in enabling the local recruitment of immunocompetent cells and supports the notion of a local antineoplastic immune response in high grade cervical intraepithelial lesions.

Abstract
We have investigated the expression in vivo and in vitro of HLA-DR in pre-invasive squamous-cell neoplasia of the uterine cervix. Immunohistochemistry of cervical biopsies demonstrated HLA-DR expression by cervical keratinocytes in 50% of cases of high-grade squamous intra-epithelial neoplasia, although the molecule was rarely expressed in low-grade squamous intra-epithelial neoplasia and was absent from normal ectocervical cells. HLA-DR-positive high-grade lesions were associated with significantly greater numbers of T lymphocytes in the immediately sub-epithelial stroma than were the HLA-DR-negative high-grade lesions. In vitro HLA-DR expression was absent from normal ectocervical epithelium, and from the HPV type 16 containing cell lines W12 (representing low-grade squamous intra-epithelial neoplasia) and CaSki and SiHa (each representing high-grade squamous intra-epithelial neoplasia), both in monolayer and in organotypic raft culture. HLA-DR expression was induced in all cell types following recombinant interferon gamma treatment. Our data suggest that the expression of HLA-DR by keratinocytes in some high-grade cervical lesions in vivo may be due to local induction of the molecule by pro-inflammatory cytokines released by immunocompetent cells. The functional significance of HLA-DR positivity in enabling an effective host immune response to neoplastic cervical keratinocytes remains unclear.

Abstract
The keratinocytes in squamous intraepithelial lesions (SILs) of the cervix show altered expression of a number of molecules involved both in the control of growth and differentiation and in cell surface interactions, particularly with components of the immune system. We have used tissue biopsies and in vitro model systems to investigate the expression in SILs of the molecules CD36 and L1, which are predominantly expressed by myelomonocytic cells but which also have functional roles in keratinocyte biology. Whereas the L1 protein (defined by the monoclonal antibody Mac387) was expressed by suprabasal and superficial cells in 12 of 12 cases of normal cervix (NCx) and in 14 of 14 cases of low-grade SILs (LG-SILs), in two of 16 cases of high-grade SILs (HG-SILs) it was entirely absent and in the remainder it was restricted to the most superficial layers. When an arbitrary grading scale was applied, L1 expression in HG-SILs proved to be significantly lower than in LG-SILs (P < .01) or in cases of NCx (P < .01). CD36 was expressed by superficial cells in four of 12 cases of NCx, in six of 14 LG-SILs, and none of 16 cases of HG-SILs (when graded, LG-SILs v HG-SILs = P < .05). The mechanisms underlying the expression of both molecules were investigated by growth in organotypic tissue culture of normal ectocervical epithelium and the cervical keratinocyte cell lines W12 (a model for LG-SILs) and CaSki and SiHa (models for HG-SILs). L1 was diffusely expressed by NCx cells and the W12 cell line, although its expression in the CaSki and SiHa cell lines was much more irregular and restricted. CD36 was occasionally present on the surface of superficial NCx and W12 cells, but was absent from CaSki and SiHa cells. Neither molecule could be induced by treatment of the cells with interferon-gamma. These data suggest that the expression of CD36 and L1 by cervical keratinocytes is related to their differentiation status rather than representing an effect of exogenous factors, such as those released by the immune cell infiltrate associated with SILs. CD36 may function as an immunoregulatory molecule on cervical keratinocytes in SILs, while L1 is more likely to be involved in the intracellular regulation of cell proliferation and maturation.

Abstract
The expression of immune associated surface antigens of keratinocytes was studied in human papillomavirus (HPV) derived lesions in order to determine whether HPV types have a regulatory role in the pathogenesis of papillomas. A series of cutaneous and mucosal lesions were immunolabeled with monoclonal antibodies to the major histocompatibility complex class 1 (beta 2-microglobulin) and 2 (HLA-DR antigens), intercellular adhesion molecule (ICAM-1) and glycoprotein CD36 (OKM5) as well as CD1a (Langerhans cells), CD4, CD8 (T cells) and CD11a (LFA1 antigen). Testing for the presence of HPV was carried out by in situ hybridization with biotinylated probes for viral DNA detection and typing. We observed a drastic reduction or a loss of beta 2-microglobulin by keratinocytes from cutaneous lesions in correlation with the disappearance of Langerhans cells. Only mild alterations were observed in mucosal lesions. HLA-DR expressed by keratinocytes was only detected in condylomas and laryngeal papillomas and was usually associated with a dense inflammatory reaction. This HLA-DR expression may be correlated with an up-regulation of ICAM-1 and the presence of LFA1 positive leukocytes, mainly of CD8 phenotype, in the epithelium. CD36 was detected on differentiated keratinocytes of all lesions; its expression seems related to the proliferation state of the lesions and probably does not represent an immune marker. The different reactivity patterns observed in cutaneous and mucosal lesions may reflect: 1. different roles for mucosal and cutaneous HPV types in the induction of immunoregulatory surface antigens of keratinocytes, or 2. the changing nature of the cytokines released by mononuclear cells and infected keratinocytes in these lesions.

Abstract
Clinical, subclinical, and latent human papillomavirus (HPV) infections are distinguished from HPV-associated neoplasia. Besides HPV additional cofactors are necessary to transform HPV infected tissue to intraepithelial or invasive neoplasia. Risk factors for the presence of HPV are high number of sexual partners, early cohabitarche, young age at first delivery, suppression and alteration of immune status, young age and hormonal influences. While the fact of a high number of sexual partners exclusively increases the risk of HPV infection, it is not known whether the other factors lead to either an increased risk for HPV infection and/or to HPV-associated neoplasia. Subclinical and latent genital HPV infections are highly prevalent. The prevalence rate depends on the sensitivity of the HPV detection system used, on age and sexual activity of the population screened, and on the number of subsequent examinations performed for each subject. Sexual transmission is the main pathway for genital HPV's, however, vertical, peripartal, and oral transmission are also possible. Seroreactivity against genital HPV may be due to an active infection or the result of contact with HPV earlier in life. Antibodies against the HPV 16 E7 protein indicate an increased risk for cervical cancer. Compared with humoral response cellular immune response is probably more important for regression of genital HPV infection: impaired cellular response is characterized by depletion of T helper/inducer cells and/or Langerhans cells and impaired function of natural killer cells and/or the infected keratinocyte. In condylomata replication and transcription of viral nucleic acids and antigen production coincide with cellular differentiation. However, the interaction between HPV and the keratinocyte on a molecular level in subclinical and latent disease is not well understood. Regression or persistence of subclinical and latent genital HPV infections as observed in longitudinal investigations show a constant come-and-go of HPV presence. Subclinical or latent cervical infections with high-risk HPV types (such as HPV 16 and 18) have an increased risk for the development of HPV-associated neoplasia.

Abstract
Langerhans cells are part of a vast system of potent antigen-presenting cells known under the name of dendritic cells. During the last decade, much has been learned on dendritic cell involvement in the immune response to infectious diseases. This review briefly summarizes our current understanding of the role played by Langerhans cells and other dendritic cells in the pathogenesis of DNA and RNA virus infections. These data may form the basis for the development of innovative approaches in the diagnosis, prevention, and treatment of viral diseases.

Abstract
Series of frozen or paraffin-embedded tissues from various body sites, taken from non-immunosuppressed or immunosuppressed patients with persistent papilloma lesions were examined for the presence of group specific antigen from human papillomavirus (HPV) by indirect immunofluorescence or HPV DNA by in situ hybridization with biotinylated probes. We have shown that it is possible to detect HPV DNA after fixation of tissues in neutral formalin, Bouin's or Baker's solution. However, the sensitivity was reduced as compared to frozen tissues. The HPV DNA was detected in nuclei of heavily infected epithelial cells such as plantar or hand warts or in dispersed cells containing high copy numbers of HPV DNA from lesions such as squamous cell carcinomas or keratoacanthomas. In premalignant or malignant lesions of both immunosuppressed or non-immunosuppressed patients, HPV DNA was rarely detected after fixation. HPV types commonly described for skin and genital samples were identified in non-immunosuppressed patients, whereas in transplant recipients oncogenic HPV type 16 was identified in benign warts as well as in premalignant or malignant lesions. Positive reactions with several HPV types were more frequent in lesions from grafted patients than from the normal population. Virus antigen was detectable more frequently in frozen sections than in fixed tissues. Our findings indicate that in situ hybridization is an appropriate and rapid technique to study the presence of HPV infection. However, numerous controls are needed to avoid misinterpretations.

Abstract
Localized absence of epithelial Langerhans cells (LC) has been shown to affect systemic immune responses, allow microbial colonization and play a possible role in carcinogenesis. Because use of smokeless tobacco is associated with abnormal oral mucosal changes and development of carcinoma, we examined lesion and control specimens from 17 current users of smokeless tobacco to determine whether lesions showed changes in LC number or antigen expression. We identified LC by immunohistochemistry with antibodies to the antigens T6, HLA-DR, HLA-DQ, and HLA-DP. Lesion specimens contained fewer LC (means of 6 LC/mm and 10 LC/mm2) than did the corresponding control specimens (means of 14 LC/mm and 30 LC/mm2), and in each pair of lesion and autologous control specimens the reduction in LC was on average 58% (range, 3% to 95%). There were no apparent differences between lesion and control specimens in the number of LC expressing each of the four marker antigens. Reductions in LC occurred in all types of smokeless tobacco-associated lesions, regardless of increased epithelial thickness or changes in keratinization. Our data indicate that smokeless tobacco reduces the number of Langerhans cells at its site of contact with the oral mucosa.

Abstract
A multiplex polymerase chain reaction (PCR) based on the simultaneous amplification of human papillomavirus (HPV) types 6/11, 16 and 18 in a single-step procedure was developed, using primers chosen in the E6-E7 region. The specificity and sensitivity of this technique have been proved by amplifying mixtures or various amounts of plasmid-containing HPV DNA; it allowed the detection of as few as 5-25 HPV DNA copies. Application of the multiplex PCR to 71 clinical samples showed that HPV DNA was detected in 80% (45/57 cases) of mucosal biopsies and 35% (5/14 cases) of cutaneous specimens. HPV 16 was predominant in high-grade CIN whereas HPV 6 and 11 were detected more frequently in genital condylomas and laryngeal papillomas. In cutaneous Bowen's disease HPV 16, 18 or 6/11 + 16 were detected and in squamous cell carcinomas HPV 6/11 or 16 were found. After sequence amplification with primers of one HPV type, the clinical samples displayed the same HPV types but the frequency of positive and coinfected lesions increased. Thus, multiplex PCR is a valuable technique for typing HPV DNA but coinfections may be underestimated.
