Although biliary tract cancers are traditionally considered rare in Western countries, their incidence and mortality rates are rising worldwide. A better knowledge of the genomic landscape of these tumor types has broadened the number of molecular targeted therapies, including angiogenesis inhibitors. The role of immune checkpoint inhibitors (ICIs) could potentially change the first-line therapeutic approach, but monotherapy with ICIs has shown disappointing results in CCA.

Following the practice-changing results observed in several hematological and solid tumors, immunotherapy with immune checkpoint inhibitors (ICIs) has been tested in cholangiocarcinoma (CCA) patients. However, ICI monotherapy has had disappointing results in CCA, and phase I-III clinical trials have assessed whether combinatorial strategies including immunotherapy plus other anticancer agents may have a synergistic activity. The TOPAZ-1 trial has recently highlighted improved survival in CCA patients receiving first-line durvalumab plus gemcitabine-cisplatin compared with gemcitabine plus cisplatin alone, and several guidelines consider adding durvalumab to the reference doublet as standard of care.

Background: Skin metastases from pancreatic neuroendocrine carcinoma (PNEC) are rare and their palliative treatment is challenging. We report our experience in the multimodal management of one of the few reported cases of metastatic PNEC with multiple visceral and subcutaneous secondary lesions, focusing on the effectiveness of palliative radiotherapy for skin metastases.

Case Presentation: A 61-years old woman affected by a metastatic PNEC - with subcutaneous growing and bleeding secondary lesions (at the scalp, right scapular region and at the back of the left thoracic wall, respectively) - obtained a successful control of visceral metastases with the use of chemotherapy and an unexpected local response of her skin metastases with palliative radiotherapy.

Desire thinking is a conscious and voluntary cognitive process orienting to prefigure images, information and memories about positive target-related experience. Desire thinking has been found to be associated with both craving and alcohol use in clinical and non-clinical populations, however its role in predicting craving and problematic drinking patterns has never been investigated using a longitudinal design. The central aim of the present study was to explore the role of desire thinking at Time 2 (3months post-baseline) in predicting craving and binge drinking and Time 3 (6months post-baseline), controlling for levels of both these constructs and Time 1 (baseline).

Circulating tumor cells (CTCs) could be considered a sign of tumor aggressiveness, but highly sensitive and specific methods of CTC detection are necessary owing to the rarity and heterogeneity of CTCs in peripheral blood. This review summarizes recent studies on tumor biology, with particular attention to the metastatic cascade, and the molecular characterization and clinical significance of CTCs. Recent technological approaches to enrich and detect these cells and challenges of CTCs for individualized cancer treatment are also discussed.

Although it is inarguable that conventional MRI (cMRI) has greatly contributed to the diagnosis and assessment of multiple sclerosis (MS), cMRI does not show close correlation with clinical findings or pathologic features, and is unable to predict prognosis or stratify disease severity. To this end, diffusion tensor imaging (DTI) with tractography and neuroconnectivity analysis may assist disease assessment in MS. We, therefore, attempted this pilot study for initial assessment of early relapsing-remitting MS (RRMS).

Background: Recently, we developed an apoptotic assay for expanding the monitoring capabilities of the circulating tumour cells (CTC) test during therapy. An automated platform for computing CTCs was integrated with a mAb (M30) targeting a neoepitope disclosed by caspase cleavage at cytokeratin 18 in early apoptosis; we showed that live CTCs were associated with progression, consistent with enhanced cell migration and invasion. The test was first applied here to mRCC.

Subsequent to the clinical trial of simvastatin in patients with relapsing remitting multiple sclerosis (RR MS), which demonstrated the ability of simvastatin to inhibit new inflammatory CNS lesion formation, the current in vitro study has characterized the mechanisms through which simvastatin inhibits Th17 cell differentiation. The anti-inflammatory effects of statins are mediated by the inhibition of isoprenylation, which ensures proper membrane insertion and function of proteins. Small GTPases, involved in multiple signal transduction pathways, are the key targets for isoprenylation.

IFN-β-1b is a first-line immunomodulatory therapy for relapsing-remitting multiple sclerosis (RR MS). However, its effects on B cells have not been characterized. In vitro studies of B cells derived from RR MS patients revealed that IFN-β-1b decreases B cells' stimulatory capacity, as detected by inhibition of the Ag-specific T cell proliferative response upon Ag presentation by IFN-β-1b-treated B cells.

In addition to cause acute and chronic liver disease, hepatitis C virus (HCV) infection is frequently associated to autoimmune disorders, such as mixed cryoglobulinemia, primary glomerulonephritis, monoclonal gammopathy of undetermined significance and post-transplant proliferative disorders. Progression to malignant phenotype of B cells may be the consequence of additional genetic events or abnormal conditions resulting from modification of host cell genes involved in the control of oncogenes and oncoproteins. In this review, we will address the potential immune disregulatory mechanism(s) underlying HCV persistence.

Chemokine CXCL13, also known as BCA-1 (B cell-attracting chemokine-1) or BLC (B-lymphocyte chemoattractant), is a major regulator of B-cell trafficking. Hepatitis C virus (HCV) infection may be associated with B-cell dysfunction and lymphoproliferative disorders, including mixed cryoglobulinemia (MC). This study evaluates circulating levels of CXCL13 protein and specific mRNA expression in chronically HCV-infected patients with and without MC.

Article Synopsis
  • Local immunosuppression and changes in sex steroids are important factors during liver regeneration, with dendritic cells (DC) playing a crucial role in the immune response.
  • Administration of fms-like tyrosine kinase 3 ligand (Flt3L) significantly increases the number of liver DCs without affecting their development, while estrogen can influence DC function and promote a Th2 immune response.
  • Following partial hepatectomy in mice, liver DCs expanded and showed increased IL-10 production, with a possible link to estrogen levels, suggesting that these DCs are vital for regulating local immune responses during liver regeneration.
