To modulate T cell function for cancer therapy one challenge is to selectively attenuate regulatory but not conventional CD4+ T cell subsets (Treg and Tconv). In this study we show how a functional dichotomy in Class IA PI3K isoforms in these two subsets of CD4+ T cells be exploited to target Treg while leaving Tconv intact. Studies employing isoform-specific PI3K inhibitors and a PI3Kδ-deficient mouse strain revealed that PI3Kα and PI3Kβ were functionally redundant with PI3Kδ in Tconv. Conversely, PI3Kδ was functionally critical in Treg, acting there to control TCR signaling, cell proliferation and survival...

Emodin is found in remedies from Traditional Chinese Medicine. Since antihyperglycaemic action was observed in rodents, non-scientific sources advertise emodin intake as a natural cure for diabetes. Emodin was admixed to high fat-food of obese mice at two doses (2 and 5g/kg; daily emodin uptake 103 and 229mg/kg). Comparison was made to ad libitum fed and to food restricted control groups, the latter showing the same weight gain as the corresponding emodin-treated groups. Emodin blunted food intake by 6% and 20% for the low and high dose, which was accompanied by proportionate reductions in weight gain...

Marfan syndrome (MFS), the founding member of connective tissue disorder, is an autosomal dominant disease; it is caused by a deficiency of the microfibrillar protein fibrillin-1 (FBN1) and characterized by involvement of three main systems; skeletal, ocular, and cardiovascular. More than one thousand mutations in FBN1 gene on chromosome 15 were found to cause MFS. Nephrotic syndrome (NS) had been described in very few patients with MFS being attributed to membranoproliferative glomerulonephritis secondary to infective endocarditis...

OBJECTIVES: Published nomograms to monitor extended-interval dosing (EID) gentamicin therapy were based on a fixed dose of 5 or 7 mg/kg. However, the average dose used for EID gentamicin regimen in our setting was about 3 mg/kg per day. We developed a new method of monitoring based on the duration of drug-free period (DFP) in a 24-h dosing interval. METHODS: Hospitalised adult patients on EID gentamicin were selected. We considered a DFP of between 2 and 8 h as appropriate...

BACKGROUND: Women carrying BRCA-mutations are facing significant challenges, including decision making regarding surveillance and risk-reducing surgery. They often report that they are left alone with these important decisions. In order to enhance the genetic counselling session we organized a group-based patient education (GPE) course for women with BRCA-mutations. The study aims were to characterize women attending a group-based patient education (GPE) course for hereditary breast and ovarian cancer, consider the usefulness of the course, evaluate symptoms of anxiety and depression among the participants, and finally investigate whether their levels of anxiety and depression changed from before to after the course session...

Molecular intermediates in T cell activation pathways are crucial targets for the therapy and prevention of graft-versus-host disease (GVHD) following allogeneic hematopoietic cell transplantation (HCT). We recently identified an essential role for cyclin dependent kinase 5 (Cdk5) in T cell activation and effector function, but the contribution of Cdk5 activity to the development of GVHD has not been explored. Using an established, pre-clinical, murine, GVHD model we reveal that Cdk5 activity is increased in key target organs early after allogeneic HCT...

The long delay in returning test results during early infant diagnosis of HIV (EID) often causes loss-to-follow-up prior to antiretroviral treatment (ART) initiation in resource-limited settings. A point-of-care (POC) test may help overcome these challenges. We evaluated the performance of the LYNX p24 Antigen POC test in Mozambique. 879 HIV-exposed infants under 18 months of age were enrolled consecutively at three primary healthcare clinics (PHC). Lancet heel-drawn blood was tested on-site by nurses using a prototype POC test for HIV Gag p24 antigen detection...

Interferon epsilon (IFNɛ) is a type I IFN that is expressed constitutively in the female reproductive tract (FRT), and contributes to protection in models of sexually transmitted infections. Using multiple cell systems, including reporter cell lines and activated peripheral blood lymphocytes (PBLs), we show that recombinant IFNɛ impairs HIV infection at stage(s) post HIV entry and up to the translation of viral proteins. Consistent with this, IFNɛ upregulated a number of host cell restriction factors that block HIV at these stages of the replication cycle...

An ultrahigh-resolution (UHR) data collection mode was enabled on a whole-body, research photon counting detector (PCD) computed tomography system. In this mode, 64 rows of [Formula: see text] detector pixels were used, which corresponded to a pixel size of [Formula: see text] at the isocenter. Spatial resolution and image noise were quantitatively assessed for the UHR PCD scan mode, as well as for a commercially available UHR scan mode that uses an energy-integrating detector (EID) and a set of comb filters to decrease the effective detector size...
