Abstract
Gynecologic cancers have varying response rates to immunotherapy due to the heterogeneity of each cancer's molecular biology and features of the tumor immune microenvironment (TIME). This article reviews key features of the TIME and its role in the pathophysiology and treatment of ovarian, endometrial, cervical, vulvar, and vaginal cancer. Knowledge of the role of the TIME in gynecologic cancers has been rapidly developing with a large body of preclinical studies demonstrating an intricate yet dichotomous role that the immune system plays in either supporting the growth of cancer or opposing it and facilitating effective treatment. Many targets and therapeutics have been identified including cytokines, antibodies, small molecules, vaccines, adoptive cell therapy, and bacterial-based therapies but most efforts in gynecologic cancers to utilize them have not been effective. However, with the development of immune checkpoint inhibitors, we have started to see the rapid and successful employment of therapeutics in cervical and endometrial cancer. There remain many challenges in utilizing the TIME, particularly in ovarian cancer, and further studies are needed to identify and validate efficacious therapeutics.

Abstract
Cancer cellular immunotherapy has made inspiring therapeutic effects in clinical practices, which brings new hope for the cure of cervical cancer. CD8+T cells are the effective cytotoxic effector cells against cancer in antitumor immunity, and T cells-based immunotherapy plays a crucial role in cellular immunotherapy. Tumor infiltrated Lymphocytes (TIL), the natural T cells, is approved for cervical cancer immunotherapy, and Engineered T cells therapy also has impressive progress. T cells with natural or engineered tumor antigen binding sites (CAR-T, TCR-T) are expanded in vitro, and re-infused back into the patients to eradicate tumor cells. This review summarizes the preclinical research and clinical applications of T cell-based immunotherapy for cervical cancer, and the challenges for cervical cancer immunotherapy.

Abstract
Cervical cancer is a top lethal cancer for women worldwide. Although screening and vaccination programs are available in many countries, resulting in the decline of new cases, this is not true for developing countries where there are many new cases and related deaths. Cancer immunotherapy through adaptive cell therapy (ACT) has been applied in clinics, but now much attention is focused on autogenic tumor-infiltrating lymphocyte (TIL)-based therapy, which has shown more specificity and better ability to inhibit tumor growth. Data from melanoma and cervical cancers confirm that tumor-specific T cells in TILs can be expanded for more specific and effective ACT. Moreover, TILs are derived from individual patients and are ready to home back to kill tumor cells after patient infusion, aligning well with personalized and precision medicine. In addition to therapy, TIL cell types and numbers are good indicators of host immune response to the tumor, and thus they have significant values in prognosis. Because of the special relationship with human papillomavirus (HPV) infection, cervical cancer has some specialties in TIL-based prognosis and therapy. In this review, we summarize the recent advances in the prognostic significance of TILs and TIL-based therapy for cervical cancer and discuss related perspectives.

CD4 + and CD8 + cell populations in HIV-positive women with cervical squamous intra-epithelial lesions and squamous cell carcinoma. Int J Infect Dis 2020; 103:370-377. [PMID: 33157285 DOI: 10.1016/j.ijid.2020.10.083] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 10/23/2020] [Accepted: 10/24/2020] [Indexed: 12/11/2022] Open
Abstract
INTRODUCTION This study aimed to analyse cervical lymphocytic populations in HIV+ and HIV- patients and correlate different cervical lesions with HIV viral load and presence of high-risk HPV types. MATERIAL AND METHODS A total of 132 histological specimens from 40 HIV+ and 72 HIV- patients were evaluated for CD4+ and CD8+ T cell distribution, presence of high-risk HPV types, peripheral blood HIV viral load and CD4+/CD8+ ratio. RESULTS High-grade squamous intraepithelial lesions (HSIL) and squamous cell carcinoma (SCC) from HIV+ patients had lower CD4+ T cell scores compared with HIV- patients. In all lesion groups, HIV+ patients presented higher epithelial and stromal CD8+ T cell scores. HIV viral load was more often detectable in patients with SCC than in those with low-grade squamous intraepithelial lesion (LSIL) (p = 0.0409). HSIL HIV+ patients had lower circulating CD4+ T cell counts (p = 0.0434) and CD4+/CD8+ ratio (p = 0.0378) compared with LSIL HIV+ patients. High-risk HPV types other than 16 and 18/45 were more prevalent in the HIV+ group. DISCUSSION These results support an imbalance between cervical CD4+ and CD8+ T lymphocytes of HIV+ patients with SIL and SCC, with increased CD8+ infiltrate density with lesion severity, even in patients with immune system recovery under cART.

The Effects of Preoperative Oral Carbohydrate on Frequency of T and NK Cells in Patients with Cervical Cancer Treated Using Neoadjuvant Chemotherapy and Surgery: A Prospective Cohort Study. BIOMED RESEARCH INTERNATIONAL 2020; 2020:2101480. [PMID: 32309426 PMCID: PMC7103029 DOI: 10.1155/2020/2101480] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 02/27/2020] [Accepted: 03/02/2020] [Indexed: 11/17/2022]
Abstract
Background Immune dysfunction can occur after neoadjuvant chemotherapy (NAC) and surgery for cancer. We investigated whether preoperative oral carbohydrate affected the postoperative percentages of T cells (CD4+ and CD8+) and natural killer (NK) cells in patients with cervical cancer treated with NAC and surgery. Methods This prospective cohort study enrolled consecutive patients with cervical cancer treated by radical hysterectomy with PLND at the Gynecologic Oncology Department of Fujian Provincial Cancer Hospital (China) between January 2018 and December 2018. Patients were divided into three groups according to the treatment method: NAC (two cycles, surgery 1 month later), NAC+CHO (chemotherapy and surgical methods same as with the NAC group but with 300 mL of oral carbohydrate administered 2 h before surgery), and non-NAC (surgery alone). Percentages of NK, CD3+, CD4+, and CD8+ cells were evaluated by flow cytometry the day after the first admission, just before surgery, immediately after tracheal tube removal, and the day after surgery. This trial is registered with NCT03872635 at clinicaltrials.com. Results The final analysis included 77 patients (non-NAC group, n = 26; NAC group, n = 25; and NAC-CHO group, n = 26). Baseline characteristics and preoperative NK, CD3+, CD4+, and CD8+ cell percentages were similar between groups. Postoperatively, all groups exhibited reductions in NK, CD3+, and CD4+ cell percentages and increases in CD8+ cell percentages (all P < 0.05). The changes in NK, CD3+, CD4+, and CD8+ cell percentages were attenuated in the NAC-CHO group (P < 0.05 vs. both other groups). Conclusion Preoperative oral carbohydrate can improve the postoperative populations of NK and T cells after the treatment of cervical cancer by NAC and surgery.

Abstract
Cytoreductive surgery is an approach to cancer treatment that aims to reduce the number of cancer cells via resection of primary tumor or metastatic deposits, in an effort to minimize a potentially immunosuppressive tumor burden, palliate symptoms, and prevent complications. Furthermore, it provides a platform for investigation of biomarkers with the goal of optimizing immunotherapy to reverse the immunosuppressive tumor microenvironment and enhance adaptive immune responses. Ultimately, our group aims to exploit the concept that successful cancer therapy is dependent upon an effective immune response. Surgery will remain an integral part of head and neck squamous cell carcinoma (HNSCC) treatment in the future, even as checkpoint inhibitors, co-stimulatory molecules, vaccines, adoptive T cell therapy and other novel agents enter clinical routine. Cytoreductive resection may provide an effective platform for immunotherapy and biomarker directed interventions to improve outcomes for patients with HNSCC.

Abstract
Cervical intraepithelial neoplasias (CIN) are closely associated with oncogenic subtypes of the human papillomavirus (HPV). In the presence of this virus, it is known that the activation or suppression of immune system is the key to the development, progression and/or regression of cervical lesions. Therefore, the objective of this study is to compare the local immune response among HIV-seropositive and seronegative patients with cervical intraepithelial neoplasia regarding the expression of T lymphocytes (CD3+, CD4+ and CD8+), B lymphocytes (CD20+) and natural killers cells (CD56+) in the cervical stroma. A cross-sectional study of paraffin blocks containing cervical tissue after conization by the Loop Electrosurgical Excision Procedure (LEEP) from 47 HIV-seropositive and 38 seronegative patients with CIN. Cervical stroma immunohistochemistry was performed in the CIN area. The Fisher's exact test was used for the statistical analysis. When HIV-seropositive and seronegative women were compared, the seropositive women had a higher count of CD8+ T lymphocytes (52.1% versus 28.9%, P<0.04). Considering CIN degree (CIN 1 and CIN 2/3), the HIV-seronegative patients with CIN 1 had a low count of CD20+B-lymphocytes (7.1%) in comparison with CIN 1 HIV seropositive and with CIN 2/3 HIV-seronegative patients, respectively 50% (P<0.018) and 54.5% (P<0.0048). The HIV infection and degree of CIN influenced the cytotoxic lymphocytes inducing an increase in the number of cells high count of CD20+ lymphocytes with CIN 1.

Abstract
Human papillomavirus (HPV) infections cause a significant global health burden, predominantly due to HPV-associated cancers. HPV infects only the epidermal cells of cutaneous and mucosal skin, without penetration into the dermal tissues. Infections may persist for months or years, contributed by an array of viral immune evasion mechanisms. However in the majority of cases immunity-based regression of HPV lesions does eventually occur. The role of the innate immune response to HPV in persistence and regression of HPV infection is not well understood. Although an initial inflammatory infiltrate may contribute to disease regression, sustained inflammation at the HPV-induced lesions, characterized by macrophage and neutrophil infiltration, has been observed in persistence. Pathogen-associated molecular patterns (PAMPs) are important in innate recognition. The double stranded DNA and an L1 and L2 capsid components of the HPV virion are potential PAMPs that can trigger signaling through cellular pattern recognition receptors, including toll-like receptors (TLR). TLR expression is increased in regressing HPV disease but is reduced in persistent lesions, suggesting a role for TLR in HPV regression. With regard to the adaptive immune response, a key indicator of regression in humans is infiltration of the lesion with both CD4 and CD8 T cells. In individuals with persistent lesions, CD8 T cell and immune suppressive regulatory T cells (Tregs) infiltrate the infection site. There is no association between persistence or regression and the presence of serum antibodies to the viral capsid antigens of HPV. There is still much to be learned about the immunological events that trigger regression of HPV disease. Understanding the viral and host factors that influence persistence and regression is important for the development of better immunotherapeutic treatments for HPV-associated disease.

Abstract
Only a small proportion of women infected with Human Papillomavirus (HPV) develop cervical cancer. Host immune response seems to play a role eliminating the viral infection and preventing progression to cancer. Characterization of tumor infiltrating lymphocytes (TILs) in cervical pre-neoplastic lesions and cervical cancer may be helpful to understand the mechanisms that mediate this protection. The aim of this study was to determine if there are differences in the localization and density (cells/mm(2)) of CD8+ T-cells, CD4+ T-cells and Tregs (CD25 + Foxp3+) in cervical pre-neoplastic lesions and cervical cancer. Immunohistochemical analysis of sections of 96 (26 CIN1, 21 CIN2, 25 CIN3, and 24 SCC) samples revealed that regardless of CIN grades, CD8+ T-cells are more abundant than CD4+, CD25+ and Foxp3+ cells in both the stroma and epithelium. There was a higher density of CD8+ cells in the stroma of cervical cancer compared to CIN3 (OR = 4.20, 95% CI 1.2-15), CIN2 (OR = 7.86, 95% CI 1.7-36.4) and CIN1 (OR = 4.25, 95% CI 1.1-17). Studies evaluating whether these cells are recruited before or after cancer progression will be helpful to understand the role of these cells in the natural history of HPV-induced lesions.

Abstract
Aims and background Cervical intraepithelial neoplasia (CIN) grade II-III is being diagnosed in younger women and, because of the reproductive age range for women and the habits associated with a modern lifestyle, is now affecting a broad age range. Surgical treatment for CIN has been associated with premature amenorrhea, low birth weight, and premature labor and birth. It is therefore imperative to develop clinical treatments for CIN, such as conservative treatment with interferons. The object of the present study was to evaluate the behavior of cytokines (IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, TNF-α, TGF β) in the serum of patients with an initial diagnosis of CIN II-III. Methods Ten patients with CIN-CIN II (60%, n = 6) and CIN III (40%, n = 4), 23 to 51 years of age and who had not received any prior treatments, were evaluated. The patients were given 3 million/UI (per cm2 of colposcopic lesion) of human recombinant IFN-α 2b by intralesional administration (18 applications on alternate days). Before treatment, in the 6th, 12th, and 18th applications, blood was collected from the patients for cytokine analysis using ELISA. Results Half of the patients had a good pathologic response; the other half, all of whom were smokers, had therapeutic failure. The average concentration of IL-12 (pg/ml) in the serum of patients who responded well to therapy was elevated from the 12th and 18th application of IFN-α 2b compared to patients who experienced therapeutic failure: 1804.0 ± 1020 vs 391.2 ± 722.3 and 1738.0 ± 2426.0 vs 448.5 ± 407.2, respectively, P <0.05. Conclusions CIN II-III treated with intralesional IFN-α 2b achieved a good response in non-smoking patients and was associated with an increase in IL-12 serum levels.

Abstract
OBJECTIVES Precancerous and cancerous cells can trigger an immune response that may limit tumor development and can be used as a prognostic marker. The aims of the present study were to quantify the presence of B and T lymphocytes, macrophages and cells expressing inducible nitric oxide synthase (iNOS) in the cervical stroma of women with grade III cervical intraepithelial neoplasia (CIN III) or in the intratumoral and peritumoral tissue of women with stage I invasive carcinoma. METHODS Cervical tissue specimens were obtained from 60 women (20 each from control tissues, CIN III and invasive carcinomas). The average ages in the control, CIN III and invasive groups were 43.9 (+/- 4.3), 35.5 (+/- 9.5), and 50 (+/- 11.2) years, respectively. The specimens were immunohistochemically labeled with antibodies to identify T lymphocytes (CD3), cytotoxic lymphocytes (CD8), B lymphocytes (CD20), macrophages (CD68) and iNOS. We evaluated the markers in the stroma above the squamocolumnar junction (control), at the intraepithelial lesion (CIN cases), and in the infiltrating tumor. Two independent observers performed the immunohistochemical analysis. RESULTS T lymphocytes, B lymphocytes, macrophages and iNOS were present more frequently (P<0.05) in the stroma of peritumoral invasive tumors compared to the controls and intratumoral invasive cancer samples. CD3+ and CD20+ lymphocytes were present more frequently in CIN III patients compared to samples from patients with intratumoral invasive cancer (P<0.05). CONCLUSION High numbers of T and B lymphocytes, macrophages and iNOS-expressing cells in the peritumoral stroma of the invasive tumors were observed. Cell migration appeared to be proportional to the progression of the lesion.

Abstract
OBJECTIVE Impairment of cell-mediated immunity in carcinoma of the cervix (CA CX) and cervical intraepithelial neoplasia (CIN) are reported. Contradictory reports exist on lymphocyte subpopulations associated with this disease. The present study aims to quantitatively analyze peripheral blood lymphocytes subsets in patients with CA CX and CIN. METHOD Systemic T lymphocyte subsets, CD19+, CD16+ and CD56+ cells in 58 CA CX and 10 CIN patients were studied. The lymphocyte phenotypes were quantified by monoclonal antibodies (anti-CD4, CD8, CD16, CD19 and CD56). RESULT Significant decrease in CD4+ cell population was observed in CA CX and CIN patients as compared to controls (P< or =0.05). CD4+/CD8+ ratio was observed to be less in CIN patients (P< or =0.001). Other lymphocyte subpopulations appeared to be comparable between the groups. CONCLUSION Results indicate immunological abnormalities in invasive CA CX and CIN patients. Study on a larger patient population may provide a biomarker for early detection of this disease.

Abstract
OBJECTIVE To determine if dividing loop electrosurgical excision procedure (LEEP) specimens to provide tissue for research increases rates of LEEP specimen misdiagnosis and recurrent cervical intraepithelial neoplasia. MATERIALS AND METHODS In this chart review, 42 women with biopsy-confirmed cervical intraepithelial neoplasia (CIN) 2,3 had up to 20% of their LEEP specimens sectioned and used for immunologic analysis. The remainder of each specimen was assessed routinely. Follow-up cytologic analyses and cervical biopsies also were assessed. This cohort was compared with a control cohort of 80 patients with biopsy confirmed CIN 2,3 whose LEEP specimens were not divided. Statistical significance was defined as a p value of < .05. RESULTS There were no statistically significant differences between the groups with regard to histologic assessment of LEEP specimens or follow-up outcomes. CONCLUSIONS Use of up to 20% of LEEP specimens for research purposes neither adversely affects histologic evaluation of LEEP specimens nor leads to poorer follow-up outcomes.

Abstract
OBJECTIVES Humoral and cellular immune responses are likely to play a key role for the clearance or persistence and progression of high risk (HR) HPV-associated cervical lesions. Although there are many studies describing the systemic T-cell responses to HPV16 and 18 proteins, few data are available regarding the cellular mucosal immune responses. We used immunohistochemistry to characterize populations of T-immune cells (CD4+, CD8+, CD45RO+) in HR-HPV-infected precancerous and cancerous lesions of the uterine cervix. METHODS Four biopsies from normal cervix, 9 CIN1 which have regressed (rCIN), 5 CIN1 which have progressed (pCIN) to high grade lesions, 13 CIN3 and 11 invasive carcinomas were included. All dysplasias and carcinomas were HR-HPV-positive and low-risk-HPV-negative. They were stained with monoclonal antibodies specific for CD4, CD8 and CD45RO and examined by microscopy. STATISTICAL ANALYSIS The Kruskal-Wallis test and the Siegel's and Castelan's method were used. RESULTS.: CD4+ cells predominated in regressing CIN1 both within the stroma and the epithelium with the highest CD4+/CD8+ ratio compared with pCIN1, CIN3 and invasive carcinoma. At the exception of CD45RO+ cells, T cells were detected with similar frequencies in both pCIN1 and CIN3. However, in 7 out of 10 CIN3, CD4+ and CD8+ cells were visible as organized lymphoid follicle structure. The CD8+ and CD45RO+ cells far exceeded the CD4+ cells in invasive cancers. CONCLUSIONS Density and distribution of immune T cells depend on the malignant potential of HR-HPV lesions. These results suggest that the studied lymphocyte subsets have an important role to fulfil during the natural history of HR-HPV-associated lesions.

Abstract
Human papillomavirus (HPV)-related disease is a significant health problem in the United States and throughout the world, especially in developing countries. Standard treatment to date has been surgical excision, but we ask the question "For what other clinically evident, virally mediated disease is the standard of treatment surgery?" The authors performed a systematic literature review and selected articles most relevant to the topic. This article reviews prevention, chemoprevention, and vaccine trials for the prevention and treatment of HPV-related disease of the genital tract. Significant advances have been made in the last decade, and the future holds promise for effective nonsurgical options for the patients with cervical dysplasia and other HPV-associated diseases.

Abstract
PROBLEM The characterization of lymphocytes issued from squamous intraepithelial lesions (SIL) and from the transformation zone (TZ), where the majority of SIL occur, is important to understand the role of immunity in SIL development. METHOD OF STUDY We compared lymphocyte populations of the TZ and SIL with those of normal exocervix, using a technique allowing for the isolation of lymphocytes, either from the epithelium or from the underlying stroma of small biopsies. RESULTS The majority of cells derived from the epithelium of all biopsies were CD8+ T cells. Some SIL-derived cultures were characterized by an increased proportion of activated TCRgammadelta+. The production of the immunosuppressive cytokine IL10 was significantly higher in lymphocyte cultures from the normal TZ in comparison with the exocervix. A decreased percentage of effector T cells was observed in cultures derived from the stroma of normal TZ (TCRgammadelta+) or SIL (CD8+) in comparison with the exocervix. CONCLUSIONS Our results suggest that a low proportion of effector T cells and IL10 production could contribute to the predisposition of the TZ to the development of SIL and to the progression of SIL to cervical cancer.

Abstract
This review paper presents the immunology findings in human immunodeficiency virus (HIV) infected and uninfected youth in the Reaching for Excellence in Adolescent Care and Health (REACH) Project within the context of basic and HIV immunology concepts. Methods employed in the study for specimen collection, management, and laboratory analysis are presented. This paper reviews published analyses of cross-sectional data; longitudinal analyses are underway. These preliminary data extend the work of others in demonstrating the potential for substantial thymic reserve in youth. This finding in HIV infected adolescents has implications for a fuller response to antiretroviral or immune-based therapies compared to that seen in adults. Dysregulation in mucosal immunity may appear before systemic HIV effects are seen and requires attention particularly to screening and treatment of genital co-infections. REACH has demonstrated gender differences in immunologic measures irrespective of HIV infection status.

Abstract
Cytotoxic T lymphocytes (Tc) play a central role in cellular immunity against cancers. The cytotoxic potential of freshly isolated tumor-infiltrating lymphocytes (TILs) is usually not expressed. This suggests the possible existence of as yet unspecified and perhaps complex immunosuppressive factors or cytokines that affect the anti-tumor capacity of these TILs in the tumor milieu. In the present study, we demonstrated for the first time that TILs derived from human cervical cancer tissue consist mainly of Th2/Tc2 phenotypes. In vitro kinetic assays further revealed that cancer cells could direct the tumor-encountered T cells toward the Th2/Tc2 polarity. Cancer cells promote the production of IL-4 and down-regulate the production of IFN-gamma in cancer-encountered T cells. The regulatory effects of cervical cancer cells are mediated mainly by IL-10, and TGF-beta plays only a synergistic role. The cancer-derived effects can be reversed by neutralizing anti-IL-10 and anti-TGF-beta Abs. IL-10 and TGF-beta are present in cancer tissue and weakly expressed in precancerous tissue, but not in normal cervical epithelial cells. Our study strongly suggests important regulatory roles of IL-10 and TGF-beta in cancer-mediated immunosuppression.

Abstract
OBJECTIVE To investigate the effects of stopping smoking on cervical Langerhans' cells and lymphocytes. DESIGN Prospective intervention study. SETTING A large family planning clinic in central London. POPULATION Women volunteers prepared to attempt to give up smoking for six months. Their most recent cervical smear showed no abnormality greater than mild dyskaryosis. METHODS The women were seen at three-month intervals for six months. Reduction in smoking was assessed by self-reporting and validated by salivary cotinine concentrations. Colposcopy and a biopsy of a normal area were performed at the first and last visits. Any area of abnormality was also biopsied at the final visit. Langerhans' cells and lymphocytes were counted. MAIN OUTCOME MEASURES Proportional changes in counts of Langerhans' cells and lymphocytes with reduction in smoking. RESULTS Reduction in smoking by 20 to 40 cigarettes per day was significantly associated with a reduction of between 6% and 16% in counts of Langerhans cells, CD8 and total lymphocytes. Heavy smoking was significantly associated (P = 0.02) with an increased chance of persistent human papillomavirus infection. The presence of candida was associated with significantly higher counts of between 41% and 47% in total lymphocytes and CD8 lymphocytes. In contrast, the presence of anaerobic vaginosis was associated with significantly lower counts of between 16% and 30% in Langerhans cells, CD4 and CD8 lymphocytes. CONCLUSIONS This large intervention study has demonstrated a clear relationship between reduction in smoking and changes in cervical immune cell counts. Future studies need to take into account cytokine interactions, which recent studies suggest may be significant in the immune response to both human papillomavirus and cervical intraepithelial neoplasia and the ever-increasing complexity of the cell-mediated immune system of the cervix.

Abstract
OBJECTIVE The objective of our study was to analyze immunocyte infiltrates in CIN lesions from HIV+ patients to assess whether local immunosuppression, defined as a decrease in T cell infiltrates, could explain the aggressive nature of CIN in HIV-infected patients. MATERIALS AND METHODS Cervical tissue was obtained from 6 HIV+ CIN patients, 6 HIV- CIN patients, who underwent LLETZ (large loop excision of the transformation zone) for CIN, and 17 normal patients who underwent hysterectomy for benign indications. The following cell surface markers were analyzed: CD20 (B cells), CD4 (T helper cells), and CD8 (T suppressor/cytotoxic cells). Each tissue section was visualized with a Leica microscope at 400x and the image was captured for analysis by Harmony Group image analysis software. RESULTS A significantly higher number of lymphocytes (both B and T cells) was detected in the stroma of HIV+/CIN tissue compared to either HIV-/CIN or normal tissue. There was also a significant increase in CD8+ cells in the HIV+/CIN group compared to HIV-/CIN or normal tissue. There was a trend toward a decreased CD4+/CD8+ ratio in the HIV+/CIN compared to the other two groups; however, this did not reach statistical significance. CONCLUSIONS This study indicates that HIV+/CIN cervical tissue has a greater number of tissue lymphocytes recruited to the neoplastic site compared to HIV- individuals. In addition, HIV+ patients may have a decreased CD4/CD8 ratio in locally infiltrating immunocytes in CIN lesions. The local immunomodulatory effects of HIV may be detectable early in infection and therefore may explain the aggressive nature of CIN in the HIV+ patient.

Abstract
BACKGROUND To investigate the clinical significance of tumor-infiltrating lymphocytes (TILs) within the tumor milieu of human cervical carcinoma, the authors quantitatively measured and compared the subpopulations of lymphocytes infiltrating the neoplastic cervix. METHODS A total of 30 patients with Stage Ia-IIa cervical carcinoma were enrolled. TILs were isolated from tissue specimens by means of a mechanical dispersal technique, and the immunocyte subsets were quantified with dual-color flow cytometry. Bulky tumor was defined as tumor size >4 cm in greatest dimension according to the 1995 staging of the International Federation of Gynecology and Obstetrics. RESULTS The CD4/CD8 ratios of TILs were reversed in both cervical squamous cell carcinoma (n = 20) and cervical adenocarcinoma (n = 10). The proportion of CD4(+) T cells was significantly lower in tumors from patients with lymph node metastasis (n = 8) than in those from patients without lymph node metastasis (n = 22) (24.5 vs. 32.7, P = 0.001), as was the reversed CD4/CD8 ratio (0.50 vs. 0.81, P = 0.001). The proportion of CD4(+) T cells was much lower in bulky tumors (n = 5) than in nonbulky tumors (n = 25) (21.4 vs. 32.5, P < 0.001), reflecting in a more strongly reversed CD4/CD8 ratio (0.41 vs. 0.81, P = 0.001). CONCLUSIONS Decreased proportions of tumor-infiltrating CD4+ T cells with reversed CD4/CD8 ratios are highly correlated with rapid tumor growth and lymph node metastasis in cervical carcinoma. The regional immune escape is of prognostic importance with regard to cancer progression.

Abstract
In this study, we have developed a simple and efficient technique for the isolation of viable lymphocytes from the epithelium and stroma of small pre-neoplastic squamous intraepithelial lesions (SIL) of the uterine cervix. Following the separation of the epithelium from the stroma using dispase II, both biopsy fragments were used to generate T lymphocytes. The stroma-derived lymphocytes were obtained by collecting and culturing the cells migrating out of the biopsy in the presence of IL2 (50 U/ml). An average of 0.7 x 10(6) and 1.4 x 10(6) lymphocytes could be obtained after 20 and 30 days of culture, respectively. For the expansion of lymphocytes derived from the pre-neoplastic epithelium (SIL) it was necessary to use a combination of irradiated peripheral blood mononuclear cells (PBMC) as a feeder layer with PHA (0.1%), in addition to IL2 (50 U/ml). Interestingly, these lymphocytes could be obtained using either allogeneic or syngeneic PBMCs. With this protocol, we were able to generate up to 100 x 10(6) lymphocytes from the epithelium, the majority of which were T lymphocytes.

Abstract
A case of multiple intracranial germ cell tumor in which a pineal tumor regressed spontaneously after resection of the cerebellar mass is reported. Immunohistochemical staining of the cerebellar mass showed that most of the infiltrating lymphocytes were positive for CD3 and CD8. The anti-Ki-67 monoclonal antibody MIB-1 staining of the resected tumor revealed a high MIB-1 positivity ratio (36.1%) among the large tumor cells, and TUNEL staining demonstrated that positivity in up to 6% of the tumor cells. Possible mechanisms responsible for this spontaneous regression including immunological responses and apoptosis induced by T lymphocytes are discussed.

Abstract
We recently reported that the SART-1 gene, encoding the SART-1(259) tumor antigen which is recognized by HLA-A26-restricted cytotoxic T lymphocytes (CTLs), is expressed in the cytosol of squamous cell carcinomas and adenocarcinomas. The present study deals with the expression of SART-1(259) and SART-1(800) antigens in uterine cancers. The SART-1(259) antigen was detected in the cytosol fraction of 4 of 8 uterine cancer cell lines, 24 of 74 (32%) uterine cancer tissues, 0 of 7 uterine myomas, and 0 of 5 non-tumorous uterine tissues. The SART-1(800) antigen was expressed in the nuclear fraction of all the uterine cancer cell lines, 41 of 74 (55%) uterine cancer tissues, 0 of 7 myomas, and 3 of 5 non-tumorous uterine tissues. The SART-1(259)+ uterine cancer cells were recognized by HLA-A24 restricted and SART-1 specific CTLs. Therefore, SART-1(259) antigen could be an appropriate vaccine candidate for a relatively large number of uterine cancer patients.

Abstract
BACKGROUND The production of the cytokine interferon gamma (IFN gamma) by activated peripheral blood mononuclear cells may be reduced in patients with invasive cervical carcinoma. This study was designed to assess the prognostic value of intratumoral IFN gamma messenger RNA (mRNA) levels in such patients. METHODS Biopsy specimens of primary cervical lesions were obtained from 27 patients with invasive squamous cell carcinoma before they received any therapy. Two prognostic groups were considered: 1) a group of 14 patients who had no apparent disease recurrence and who were alive 2 years after diagnosis (good-prognosis group) and 2) a group of 13 patients who had disease recurrence or died during the 2-year follow-up (poor-prognosis group). A competitive reverse transcription-polymerase chain reaction assay was used to measure levels of IFN gamma and beta actin mRNA. The expression of human leukocyte antigen (HLA) class II proteins (which is stimulated by IFN gamma) in tumor cells was studied by immunostaining. RESULTS Tumor specimens from all 14 patients in the good-prognosis group contained more than 10(3) IFN gamma mRNA copies per 5 x 10(5) beta actin mRNA copies, whereas tumor specimens from only six of the 13 patients in the poor-prognosis group contained this level of IFN gamma mRNA (two-sided P = .006). No clear relationship was observed between levels of IFN gamma mRNA and T-cell or natural killer cell infiltration in tumors; however, a statistically significant association was observed between HLA class II expression on tumor cells and IFN gamma mRNA levels (two-sided P = .01). CONCLUSIONS A subgroup of poor-prognosis cervical carcinoma patients who have low levels of intratumoral IFN gamma mRNA was identified.

Abstract
To investigate the activation status of tumor-infiltrating lymphocytes (TILs) within the tumor milieu of human cervical carcinoma, we quantitatively measured and compared the activation markers on lymphocyte subpopulations which infiltrating normal and neoplastic cervix. A total of 20 patients with stage IA to IIA cervical cancer (cancer group) and 10 women with normal cervix (control group) were enrolled in this study. Mononuclear cells were isolated from tissue specimens by mechanical dispersal technique and three-color flow cytometry was utilized for the quantification of activation markers on lymphocyte subsets. Compared with control group, lymphocytes isolated from cancer tissue consisted of higher proportions of B cells (7.23% +/- 4.49% vs. 3.67% +/- 3.19%, P = 0.016) and T cells (72.33% +/- 8.70% vs. 53.15% +/- 17.36%, P = 0.004), but an inverted CD4:CD8 ratio (0.74 +/- 0.27 vs. 1.14 +/- 0.28, P = 0.002) and decreased NK cells (7.53% +/- 4.33% vs. 16.00% +/- 11.82%, P = 0.035). Low expression of CD25, but not CD69 and HLA-DR was observed on both CD4+CD3+ and CD8+CD3+ T cells derived from cervical cancer (P < 0.0001). Further dual activation marker analysis demonstrated that the expression of CD25 was dissociated from CD69 and HLA-DR on the same TILs in cancer tissue (P < 0.001). TILs in the tumor microenvironment can be functionally inhibited and lose the ability of clonal proliferation due to depressed expression of CD25.

Abstract
Recombinant human papillomavirus (HPV) type 16 L1 virus-like particles (VLPs) expressed in the baculovirus system were used to investigate the cellular immune response to human papillomavirus type 16. The cell-mediated immune response was evaluated through immunization of mice with HPV 16 L1 virus-like particles using a lymphoproliferation assay and cytokine production and cytometric analysis of lymphocyte subsets. A significant proliferative response was observed which was associated with secretion of both interferon-gamma and interleukin-2. FACS analysis of splenic lymphocytes revealed that CD8+ T-cells were increased in the immunized mice. These results demonstrate that HPV 16 L1 VLPs induce a T-cell response characterized by a Th1 profile and confirm that the HPV 16 VLP is a reasonable candidate for vaccine development.

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
Although T lymphocytes are present in the genital mucosa, their function in sexually transmitted diseases is unproven. To determine if cervical T cells mediate HIV-specific cytolysis, mononuclear cells in cytobrush specimens from HIV-1-infected women were stimulated in vitro with antigen. Resultant cell lines lysed autologous targets expressing HIV-1 proteins in 12/19 (63%) subjects, and these responses were detected intermittently on repeated visits. All 8 subjects with blood CD4+ counts > or =500 cells/microl had HIV-1-specific cervical CTL, whereas only 4/11 with counts <500 cells/microl had detectable responses (P = 0.008). Class II MHC-restricted CD4+ CTL clones lysed targets expressing Env gp41 or infected with HIV-1. Class I MHC-restricted CD8+ clones recognized HIV-1 Gag- or Pol-expressing targets, and the epitopes were mapped to within 9-20 amino acids. Comparisons of intra-individual cervical and blood CTL specificities indicate that epitopes recognized by CTL in the cervix were commonly recognized in the blood. These studies provide the first definitive evidence for an MHC-restricted effector function in human cervical lymphocytes.
