Chimeric T cell receptors (CARs) combine extracellular antigen recognition domains and T cell activation components in single molecules. CAR gene transfer thereby allows to generate T cells with engineered specificities. The translational development of CAR-based T cell therapies is most advanced in B cell cancers where CAR-engineered T cells against the B lineage antigen CD19 have generated impressive results in early clinical trials. CARs are now also explored as tools to eliminate autoreactive B cell clones and to engineer T cells with immunosuppressive function for preventing pathological auto- or alloresponses...

Budd-Chiari syndrome (BCS) is a rare disease with an incidence of 0.1 to 10 per million inhabitants a year caused by impaired venous outflow from the liver mostly at the level of hepatic veins and inferior vena cava. Etiological factors include hypercoagulable conditions, myeloprolipherative diseases, anatomical variability of the inferior vena cava, and environmental conditions. Survival rates in treated patients range from 42 to 100% depending on the etiology and the presence of risk factors including parameters of Child-Pugh score, sodium and creatinine plasma levels, and the choice of treatment...

MEDI-570 is a fully human afucosylated monoclonal antibody (MAb) against Inducible T-cell costimulator (ICOS), highly expressed on CD4+ T follicular helper (TFH) cells. Effects of MEDI-570 were evaluated in an enhanced pre-postnatal development toxicity (ePPND) study in cynomolgus monkeys. Administration to pregnant monkeys did cause any abortifacient effects. Changes in hematology and peripheral blood T lymphocyte subsets in maternal animals and infants and the attenuated infant IgG immune response to keyhole limpet hemocyanin (KLH) were attributed to MEDI-570 pharmacology...

The C - X - C chemokine receptor 4 (CXCR4) and its natural ligand CXCL12 are key factors in the process of cell migration, homing of hematopoietic stem cells to the bone marrow, and represent important mediators of angiogenesis and cell proliferation. The CXCR4/CXCL12 interplay can be disrupted by CXCR4 antagonists such as Plerixafor which are already in daily clinical use, i.e. for mobilization and subsequent harvesting of hematopoietic progenitor cells and stem cell transplantation. In a pathological condition, involvement in the process of metastasis and homing of cancer cells to a protective niche has been described, making CXCR4 an attractive target for imaging and treatment of malignant diseases...

Human lactoferrin (hLf), an iron-binding multifunctional cationic glycoprotein secreted by exocrine glands and by neutrophils, is a key element of host defenses. HLf and bovine Lf (bLf), possessing high sequence homology and identical functions, inhibit bacterial growth and biofilm dependently from iron binding ability while, independently, bacterial adhesion to and the entry into cells. In infected/inflamed host cells, bLf exerts an anti-inflammatory activity against interleukin-6 (IL-6), thus up-regulating ferroportin (Fpn) and transferrin receptor 1 (TfR1) and down-regulating ferritin (Ftn), pivotal actors of iron and inflammatory homeostasis (IIH)...

Oral mucositis (OM) is one of the cancer chemotherapy-related side effects which can affect the quality of life of affected patients. This study was designed to investigate the healing effect of Elaeagnus angustifolia in 5-flurouracil (5-FU)-induced OM in golden hamster. Fifty-six adult male golden hamsters received three intraperitoneal injections of 5-FU at a dose of 60 mg/kg on days 0, 5, and 10. The cheek pouch mucosa was scratched superficially under local anesthesia. Then, two horizontal scratches were made across the everted cheek pouch on days 3 and 4...

Necropsy (or autopsy) is the post mortem dissection of an animal to examine and collect organs and tissues in order to understand the effects and causes of disease. The systematic harvesting of samples at necropsy is an essential step in defining the reason for an unexpected death and in characterizing the features (i.e., phenotype) of a newly discovered condition. Phenotypic evaluation of young (neonatal and juvenile) mice emphasizes morphologic (macroscopic and microscopic) techniques and biochemical (clinical chemistry, hematologic, and molecular) analyses...

Myeloid malignancies are characterized by an extreme molecular heterogeneity, and many efforts have been made in the past decades to clarify the mechanisms underlying their pathogenesis. In this scenario SET binding protein 1 (SETBP1) has attracted a lot of interest as a new oncogene and potential marker, in addition to its involvement in the Schinzel-Giedon syndrome (SGS). Our review starts with the analysis of the structural characteristics of SETBP1, and extends to its corresponding physiological and pathological functions...

Multi-gene detection at the single-cell level is desirable to enable more precise genotyping of heterogeneous hematology and oncology samples. This study aimed to establish a single-cell multi-gene fluorescence in situ hybridization (FISH) method for use in molecular pathology analyses. Five fluorochromes were used to label different FISH gene probes, and 5 genes were detected using a five-color FISH protocol. After the first hybridization, the previous FISH probe set was stripped, and a second set of five-color FISH probes was used for rehybridization...

OBJECTIVE: Patients with hematological malignancies frequently encounter spine-related symptoms, which are caused by disease itself or process of treatment. However, there is still lack of knowledge on their epidemiology and clinical courses. The purpose of this article is to review clinical presentations and surgical results for spinal involvement of hematologic malignancies. METHODS: From January 2011 to September 2014, 195 patients (98 males and 97 females) suffering from hematological malignancies combined with spinal problems were retrospectively analyzed for clinical and radiological characteristics and their clinical results...

Mastocytosis can be associated with other clonal or non-clonal hematologic diseases as well as a variety of non-hematologic malignancies. A 75-year-old Caucasian male patient was referred to us with a 5-month history of neutrophilic leukocytosis and mild splenomegaly. He had developed a cutaneous melanoma sixteen years ago. According to the clinical and pathological features, a final diagnosis of systemic mastocytosis was established. The patient started treatment with interferon-α at a dose of 3 MIU/day, combined with low doses of prednisone...

BACKGROUND/AIMS: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy that typically presents in the form of skin manifestations with or without lymph node and bone marrow involvement. Given its rarity and recent recognition as a distinct pathological entity, no standard of treatment exists for this aggressive disease and its prognosis is particularly dismal. METHODS: We retrospectively analyzed clinical features and treatment outcomes of patients who were diagnosed with BPDCN between 2000 and 2014...

Multiple myeloma (MM) accounts for ∼13% of all hematologic malignancies. Bortezomib treatment is effective in MM, but can be complicated with neurological side effects. We describe a patient with symptomatic MM who had a reversible metabolic myopathy associated with bortezomib administration and pathologically characterized by excessive storage of lipid droplets together with mitochondrial abnormalities. In a single-center prospective study, 14 out of 24 patients with symptomatic MM were treated with bortezomib and, among these, 7 developed muscular signs and/or symptoms...

There are few established treatments for patients with non-small-cell lung cancer (NSCLC) with interstitial lung disease (ILD). The safety and efficacy of albumin-bound paclitaxel (nab-paclitaxel) in combination with carboplatin is uncertain, although the combination of carboplatin and paclitaxel is the most common regimen for treating NSCLC patients with ILD. A total of 9 NSCLC patients with ILD, treated between April 2013 and March 2016, were retrospectively investigated. Carboplatin (AUC 5-6) was administered on day 1 and nab-paclitaxel on days 1, 8 and 15, every 4-6 weeks...

Aggressive systemic mastocytosis is a rare hematologic neoplastic disease that presents with a poor prognosis and low survival rate. It typically manifests with symptoms associated to mast cell release of bioactive substances, causing anaphylaxis, flushing, autonomic and hemodynamic instability, gastric distress and headache. Moreover, more than 95% of cases are related to a mutation in codon 816 of the KIT gene, located on human chromosome 4q12 which codes for a type III receptor tyrosine kinase. We present a 78 year-old Hispanic man diagnosed with the aggressive subtype of systemic mastocytosis, who had an atypical manifestation and a KIT negative variant...
