Real-world outcomes of mepolizumab for the treatment of severe eosinophilic asthma in Canada: an observational study.

Background: Mepolizumab, the first widely available anti-interleukin 5 biologic, targets eosinophilic inflammation and has been shown in clinical trials to reduce exacerbations, oral corticosteroid dependence, and healthcare utilization in patients with severe asthma. The impact of mepolizumab in a real-world, publicly funded healthcare setting is unknown. The objective of this study was to describe the demographics and clinical characteristics of real-world patients receiving mepolizumab, and to compare asthma-related outcomes and associated asthma-related costs before and during mepolizumab use.

Glycoprotein 2 is a specific cell surface marker of human pancreatic progenitors.

PDX1/NKX6-1 pancreatic progenitors (PPs) give rise to endocrine cells both in vitro and in vivo. This cell population can be successfully differentiated from human pluripotent stem cells (hPSCs) and hold the potential to generate an unlimited supply of β cells for diabetes treatment. However, the efficiency of PP generation in vitro is highly variable, negatively impacting reproducibility and validation of in vitro and in vivo studies, and consequently, translation to the clinic.

Recent advances in cell replacement therapies for the treatment of type 1 diabetes.

Exogenous insulin administration is currently the only treatment available to all type 1 diabetes patients, but it is not a cure. By helping to regulate circulating blood glucose levels, it has significantly improved life expectancy, but there are still long-term complications associated with the disease that may be preventable with a treatment strategy that can provide better glycemic control. Isolated islet (or whole pancreas) transplantation, xenotransplantation, and the transplant of human pluripotent stem cell-derived β-cells provide the potential to restore endogenous insulin production and reestablish normoglycemia.

Dlk1 up-regulates Gli1 expression in male rat adrenal capsule cells through the activation of β1 integrin and ERK1/2.

The development and maintenance of the zones of the adrenal cortex and their steroidal output are extremely important in the control of gluconeogenesis, the stress response, and blood volume. Sonic Hedgehog (Shh) is expressed in the adrenal cortex and signals to capsular cells, which can respond by migrating into the cortex and converting into a steroidogenic phenotype. Delta-like homologue 1 (Dlk1), a member of the Notch/Delta/Serrate family of epidermal growth factor-like repeat-containing proteins, has a well-established role in inhibiting adipocyte differentiation.

Heat shock induces rapid resorption of primary cilia.

Primary cilia are involved in important developmental and disease pathways, such as the regulation of neurogenesis and tumorigenesis. They function as sensory antennae and are essential in the regulation of key extracellular signalling systems. We have investigated the effects of cell stress on primary cilia.
