Bladder cancer, a unique model to understand cancer immunity and develop immunotherapy approaches.

With the mechanistic understanding of immune checkpoints and success in checkpoint blockade using antibodies for the treatment of certain cancers, immunotherapy has become one of the hottest areas in cancer research, with promise of long-lasting therapeutic effect. Currently, however, only a proportion of cancers have a good response to checkpoint inhibition immunotherapy. Better understanding of the cancer response and resistance mechanisms is essential to fully explore the potential of immunotherapy to cu...

Transethnic associations among immune-mediated diseases and single-nucleotide polymorphisms of the aryl hydrocarbon response gene ARNT and the PTPN22 immune regulatory gene.

Because immune responses are sensitive to environmental changes that drive selection of genetic variants, we hypothesized that polymorphisms of some xenobiotic response and immune response genes may be associated with specific types of immune-mediated diseases (IMD), while others may be associated with IMD as a larger category regardless of specific phenotype or ethnicity.

Autologous hematopoietic stem cell transplantation for human immunodeficiency virus associated gastric Burkitt lymphoma: A case report.

HIV-related lymphoma, especially non-Hodgkin lymphoma, is one of the most common malignant tumors in HIV/acquired immune deficiency syndrome (AIDS) patients. Autologous hematopoietic stem cell transplantation (AHSCT) for the patients with Burkitt lymphoma (BL) is needed to be further explored.

Immune response to chronic Toxocara canis infection in a mice model.

The zoonotic nematode Toxocara canis causes larvae migrans syndrome that induces an immune response characterised by the production of antibodies and eosinophilia. A Th2 polarization has been associated with the infection, but there are still details of the cellular and humoral immune response that need to be described. Thus, the aim of this study is to describe the systemic host immune response to T. canis chronic infection in a mouse model.

CD30+ large B cell lymphoma with anaplastic features and complete loss of B cell marker expression arising from follicular lymphoma.

Follicular lymphoma is the most common indolent B cell lymphoma, accounting for 20% of all non-Hodgkin lymphomas. Transformation of follicular lymphoma to a more aggressive lymphoma is a well-characterized phenomenon that occurs in 30% of cases at 10 years following diagnosis . Follicular lymphoma most frequently transforms to diffuse large B cell lymphoma. Transformation to other neoplasms that retain expression of immunophenotypic markers of the B cell transcriptional program (Burkitt lymphoma, B lymphob...

T cell-mediated immunity in CBA mice during Schistosoma japonicum infection.

Characterisation of the cellular immune response to schistosomiasis is well established for Schistosoma mansoni but a comprehensive description of T cell-mediated immune responses against S. japonicum infection is lacking. Accordingly, 20 CBA mice were infected with cercariae of S. japonicum and the immune response at different time points was determined. Mouse spleen and liver lymphocytes were isolated from the mice and stimulated with schistosomal adult worm antigen preparation (SWAP) and schistosomal sol...

Bio-Mimetic Magnetic Nanostructures: A Theranostic Platform Targeting Lipid Metabolism and Immune Response in Lymphoma.

B cell lymphoma cells depend upon cholesterol to maintain pro-proliferation and pro-survival signaling via the B cell receptor. Targeted cholesterol depletion of lymphoma cells is an attractive therapeutic strategy. We report here high-density lipoprotein mimicking magnetic nanostructures (HDL-MNS) that can bind to the high-affinity HDL receptor, scavenger receptor type B-1 (SR-B1), and interfere with cholesterol flux mechanisms in SR-B1 receptor positive lymphoma cells, causing cellular cholesterol depleti...

Primary and acquired resistance mechanisms to immune checkpoint inhibition in Hodgkin lymphoma.

Hodgkin lymphoma is a B cell derived malignancy characterized by a low number of tumor cells within an environment consisting of inflammatory cells. Recently, immune checkpoint blockade targeting the PD-1-PD-L1 axis has shown to be a great success in relapsed and refractory Hodgkin lymphoma patients. However, complete responses are scarce and median progression-free survival is limited to around 11-15 months. Efficiency of PD-1 blockade in HL might be dependent on CD4+ T cells, but also tumor associated m...

Immune response and protection against Lawsonia intracellularis infections in pigs.

Lawsonia intracellularis are Gram-negative, obligate intracellular bacteria that cause proliferative enteropathy (PE), an economically important disease for the pig industry. Numerous reviews have been published on the characteristics and pathogenesis of this bacterium since its isolation and taxonomic characterization, with most reviews only partially covering how the host immune response develops during infection and the immune correlates of protection. With the development of increasingly more sophistica...

Feasibility of postoperative 3-tesla diffusion tensor imaging in cervical spondylotic myelopathy: A comparison of single-shot EPI and multi-shot EPI.

To explore the feasibility of postoperative high-tesla DTI in CSM and optimize its acquisition parameters using both single-shot (SS) echo-planar imaging (EPI) and multi-shot (MS) EPI, and to evaluate correlation between image degradation and operative methods.

Ascaris lumbricoides coinfection reduces tissue damage by decreasing IL-6 levels without altering clinical evolution of pulmonary tuberculosis or Th1/Th2/Th17 cytokine profile.

Immunological control of Mycobacterium tuberculosis infection is dependent on the cellular immune response, mediated predominantly by Th1 type CD4+ T cells. Polarization of the immune response to Th2 can inhibit the host immune protection against pathogens. Patients with tuberculosis coinfected with helminths demonstrate more severe pulmonary symptoms, a deficiency in the immune response against tuberculosis, and an impaired response to anti-tuberculosis therapy.

Essential role of TNF-α in gamma c cytokine aided crosstalk between dendritic cells and natural killer cells in experimental murine lymphoma.

Cooperative and cognitive interaction between the dendritic cells and natural killer cells was investigated for demonstrating the anti-tumor activity against an aggressive murine lymphoma, treated with doxorubicin. Crosstalk between the dendritic cells and the natural killer cells significantly reduced the proliferation of Dalton's lymphoma cells in a dose dependent manner. Treatment of Dalton's lymphoma cells with doxorubicin in vitro enhances the effects of crosstalk against the target cells. This crossta...

Role of peptide transporter 2 and MAPK signaling pathways in the innate immune response induced by bacterial peptides in alveolar epithelial cells.

The innate immune response induced by bacterial peptidoglycan peptides, such as γ-d-glutamyl-meso-diaminopimelic acid (iE-DAP), is an important host defense system. However, little is known about the innate immune response in the lung alveolar region. In this study, we examined induction of the innate immune response by iE-DAP in human alveolar epithelial cell lines, NCI-H441 (H441) and A549.

Who drops out and when? Predictors of non-response and loss to follow-up in a longitudinal cohort study among STI clinic visitors.

Response rates in health research are declining, and low response rates could result in biased outcomes when population characteristics of participants systematically differ from the non-respondents. Few studies have examined key factors of non-response beyond demographic characteristics, such as behavioral and psychological factors. The aim of the current study was to identify predictors of non-response and loss to follow-up in a longitudinal sexual health study.

Impact of double/triple hit pathology on rates and durability of RT response among patients with relapsed/refractory large B-cell lymphoma.

Double/triple-hit lymphomas (DHL/THL), also known as high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements, are associated with chemoresistance and inferior survival. However, whether RT efficacy is altered in DHL/THL is less well characterized. Among patients with relapsed/refractory (R/R) large B-cell lymphoma (LCBL), we compared rates and durability of response between patients with and without DHL/THL.

Romidepsin treatment for relapsed or refractory peripheral and cutaneous T-cell lymphoma - real-life data from a national multicenter observational study.

Romidepsin is a class I selective histone deacetylase (HDAC) inhibitor approved by the FDA for relapsed/refractory (R/R) CTCL and PTCL, treated with at least one prior systemic therapy. Currently, there is paucity of real-life data on the efficacy and safety of romidepsin in R/R T cell lymphoma. This national, multicenter study presents real-life data on the efficacy and safety of romidepsin in R/R T cell lymphoma. Patients diagnosed and treated with romidepsin for R/R CTCL or PTCL between 2013 and 2018 wer...

The prognostic value of platelet-lymphocyte ratio and neutrophil-lymphocyte ratio in the treatment response and survival of patients with peripheral T-cell lymphoma.

Peripheral T-cell lymphoma (PTCL) is a rare and highly heterogeneous non-Hodgkin lymphoma (NHL). Although a few prognostic models have been put forward to predict the prognosis of PTCL, some patients with poor prognosis remain unidentified. Therefore, we conducted a retrospective study of 213 adult PTCL patients and assessed the prognostic role of platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) in the complete response (CR) and survival of PTCL patients. Patients with PLR ≥ 232.5...

Pretreatment prognostic nutritional index as a novel biomarker in non-small cell lung cancer patients treated with immune checkpoint inhibitors.

Immune checkpoint inhibitors (ICIs) have been established as a novel strategy for non-small cell lung cancer (NSCLC) therapy. However, a definitive biomarker that can predict response to ICI therapy remains unestablished. The prognostic nutritional index (PNI) is used to assess immune-nutritional conditions and is a prognostic factor in patients with various malignancies; however, its usefulness as a biomarker of response to ICI therapy and survival outcomes in NSCLC patients is unknown. Thus, we retrospect...

Evaluation of the antibody response to the EBV proteome in EBV-associated classic Hodgkin lymphoma.

The humoral immune response to Epstein-Barr virus (EBV) in classic Hodgkin lymphoma (cHL) stratified by EBV tumor status is unclear. We examined IgG and IgA antibody responses against 202 protein sequences representing 86 EBV proteins using a microarray and sera from 139 EBV-positive cHL cases, 70 EBV-negative cHL cases, and 141 population-based controls frequency matched to EBV-positive cHL cases on sex and age by area (UK, Denmark, and Sweden). We leveraged existing data on the proportion of circulating B...

Hope After Salvage Therapy Fails: Novel Agents for Relapsed/Refractory Hodgkin Lymphoma.

Hodgkin lymphoma is a highly curable malignancy, with an excellent prognosis. However, around 10% to 25% of patients will have primary refractory or relapsed disease, despite using risk-adapted strategies. The standard of care for patients with relapsed/refractory Hodgkin lymphoma has been cytoreduction using salvage chemotherapy, followed by high-dose chemotherapy and autologous hematopoietic stem cell transplantation (AHSCT). Studies have shown that AHSCT produces a durable response rate of 50%, and that ...

Clinical features and treatment outcomes of Hodgkin lymphoma: A retrospective review in a Malaysian tertiary hospital.

Classical Hodgkin lymphoma (cHL) is a clinicopathologically unique, aggressive lymphoma arising from germinal center B-cells and is one of the most curable hematological malignancies. This study aimed to determine the clinical course, treatment regimens, response rates, and survival data of patients diagnosed with cHL in a tertiary center.

Progression of Disease Within 24 Months in Follicular Lymphoma Is Associated With Reduced Intratumoral Immune Infiltration.

Understanding the immunobiology of the 15% to 30% of patients with follicular lymphoma (FL) who experience progression of disease within 24 months (POD24) remains a priority. Solid tumors with low levels of intratumoral immune infiltration have inferior outcomes. It is unknown whether a similar relationship exists between POD24 in FL.

Innate immune response in retinal homeostasis and inflammatory disorders.

Innate immune cells such as neutrophils, monocyte-macrophages and microglial cells are pivotal for the health and disease of the retina. For the maintenance of retinal homeostasis, these cells and immunosuppressive molecules in the eye actively regulate the induction and the expression of inflammation in order to prevent excessive activation and subsequent tissue damage. In the disease context, these regulatory mechanisms are modulated genetically and/or by environmental stimuli such as damage-associated mo...

Surveillance scanning in lymphoma.

Although the role of imaging in the management of most lymphomas is well established at baseline, during treatment, and following treatment, surveillance imaging after complete response remains controversial despite the numerous studies that have investigated follow-up computed tomography, positron emission tomography, and magnetic resonance imaging over the past 20 years. Although robust data do not support an impact of this strategy on survival in Hodgkin lymphoma, diffuse large B-cell lymphoma, or follic...
