REVIEW
W Pönisch, R Alten, C Baerwald
Immune checkpoint inhibitors (ICI) have dramatically changed the face of cancer treatment and are gaining in importance. The ICIs have now been approved for the treatment of advanced cancers, including melanoma, non-small-cell and small cell lung cancers, renal cell carcinoma, Hodgkin's lymphoma, head and neck cancers and urothelial carcinoma and further indications are to be expected. The organs most affected by an autoimmune reaction are the intestines, the musculoskeletal system, skin, endocrine organs, the liver and the lungs...

A close relative of poliovirus, enterovirus 71 (EV71) is regarded as an important neurotropic virus of serious public health concern. EV71 causes Hand, Foot and Mouth Disease and has been associated with neurological complications in young children. Our limited understanding of the mechanisms involved in its neuropathogenesis has hampered the development of effective therapeutic options. Here, using a two-dimensional proteomics approach combined with mass spectrometry, we have identified a unique panel of host proteins that were differentially and dynamically modulated during EV71 infection of motor-neuron NSC-34 cells, which are found at the neuromuscular junctions where EV71 is believed to enter the central nervous system...

PURPOSE OF REVIEW: Since the first liver transplantation in the early 1960s, there have been significant improvements in the recipients' long-term outcome. Patients who have undergone transplantation are exposed to a high risk of developing neoplastic disease, not only because of their chronic immunosuppression, but also related to physiological aging, lifestyle, chronic viral infections, liver disease cause, and carcinogenic immunosuppressants. The present review covers the latest and most relevant data on de novo neoplasms after liver transplantation, and discusses their implications for clinical practice...

REVIEW
Xiao Qian Wang, Sarah Palmer
Antiretroviral therapy effectively suppresses, but does not eradicate HIV-1 infection. Persistent low-level HIV-1 can still be detected in plasma and cellular reservoirs even after years of effective therapy, and cessation of current treatments invariably results in resumption of viral replication. Efforts to eradicate persistent HIV-1 require a comprehensive examination of the quantity and genetic composition of HIV-1 within the plasma and infected cells located in the peripheral blood and tissues throughout the body...

BACKGROUND: Helicobacter pylori (H. pylori) infection causes elevation of lipid peroxidation product malondialdehyde (MDA) and this association may be due to the bacterium causing reactive oxygen species-mediated damage to DNA in the gastric epithelium. The aim of this study was to investigate the gastric juice MDA levels in relation to H. pylori infection and associated gastric diseases. METHODS: Gastric juice samples were obtained from 117 patients undergoing endoscopy, and gastric juice MDA levels were determined by high-performance liquid chromatography (HPLC) system...

Hepatitis C virus infection causes chronic liver disease that leads to cancer-related mortality. Presently around 30% of the HCV (infected) affected population get rid of the infection through spontaneous disease clearance. This phenomenon is conducted by a set of reported immune candidate genes. Hence, this study focuses only on these immune-response related genes with aid of network approach, where the idea is to disseminate the network for better understanding of key functional genes and their transcription control activity...

The B-lymphotropic Epstein-Barr virus (EBV), pandemic in humans, is rapidly controlled on initial infection by T cell surveillance; thereafter, the virus establishes a lifelong latent infection in the host. If surveillance fails, fatal lymphoproliferation and lymphomagenesis ensue. The initial T cell response consists of predominantly CD8+ cytotoxic T cells and a smaller expansion of CD4+ cells. A major approach to treating EBV-associated lymphomas is adoptive transfer of autologous or allogeneic T cells that are stimulated/expanded on EBV-transformed B cells...

OBJECTIVES: Previous studies found higher levels of physical activity to be protective against infections and that short and long sleep negatively affects the immune response. However, these relationships remain debatable. We aimed to investigate if physical activity and sleep habits affect incidence of upper respiratory tract infections (URTI) in a prospective cohort study. METHODS: A total of 2,038 adults aged 25-64 years served as a random sample of the gainfully employed population of an industrial town in Sweden...
