Post-doctoral collectives: pathways to a more fruitful experience?
No two post-doctoral experiences are the same, running the gamut of rearview mirror descriptions from "...the best time of my working life..." to an angst-filled "...three years to lay the golden egg." Traditionally relying principally on one's advisor, labmates, and collaborators for support (both material and psychological), post-docs now have dedicated professional organizations in their corners. These include the
National Postdoctoral Association
and several unions, the first of which (
) was chartered within the University of California system in 2008. These organizations focus on improving
compensation, health care options, benefits, and overall working conditions for post-doctoral workers. As with all matters subject to the ebb and flow of research funding, some
question the sustainability
of solutions offered through unionization. What say you?

Developmental Progression of the Coronary Vasculature in Human Embryos and Fetuses
Anatomical Record (Hoboken)
Although considerable advances in our understanding of mammalian and avian embryonic coronary development have occurred during the last decade, our current knowledge of this topic in humans is limited. Accordingly, the aim of this study was to determine if the development of the human coronary vasculature in humans is like that of other mammals and avians. Read more
Small Rho GTPase-mediated actin dynamics at endothelial adherens junctions
VE-cadherin-based cell-cell junctions form the major restrictive barrier of the endothelium to plasma proteins and blood cells. The function of VE-cadherin and the actin cytoskeleton are intimately linked. Vascular permeability factors and adherent leukocytes signal through small Rho-GTPases to tightly regulate actin cytoskeletal rearrangements in order to open and re-assemble endothelial cell-cell junctions in a rapid and controlled manner. Read more
F-actin-rich contractile endothelial pores prevent vascular leakage during leukocyte diapedesis through local RhoA signalling
During immune surveillance and inflammation, leukocytes exit the vasculature through transient openings in the endothelium without causing plasma leakage. However, the exact mechanisms behind this intriguing phenomenon are still unknown. Here we report that maintenance of endothelial barrier integrity during leukocyte diapedesis requires local endothelial RhoA cycling. Read more
Acid Sphingomyelinase-Derived Ceramide Regulates ICAM-1 Function during T Cell Transmigration across Brain Endothelial Cells
Journal of Immunology
Multiple sclerosis (MS) is a chronic demyelinating disorder of the CNS characterized by immune cell infiltration across the brain vasculature into the brain, a process not yet fully understood. We previously demonstrated that the sphingolipid metabolism is altered in MS lesions. Read more
Plasminogen Activator Inhibitor-1 Controls Vascular Integrity by Regulating VE-Cadherin Trafficking
Plasminogen activator inhibitor-1 (PAI-1), a serine protease inhibitor, is expressed and secreted by endothelial cells. Patients with PAI-1 deficiency show a mild to moderate bleeding diathesis, which has been exclusively ascribed to the function of PAI-1 in down-regulating fibrinolysis. Read more
Crossing the Vascular Wall: Common and Unique Mechanisms Exploited by Different Leukocyte Subsets during Extravasation
Mediators of Inflammation
Leukocyte extravasation is one of the essential and first steps during the initiation of inflammation. Therefore, a better understanding of the key molecules that regulate this process may help to develop novel therapeutics for treatment of inflammation-based diseases such as atherosclerosis or rheumatoid arthritis.

High density lipoprotein modulates thrombosis by preventing von Willebrand factor self-association and subsequent platelet adhesion
The ability of von Willebrand factor (VWF) to initiate platelet adhesion depends on the number of monomers in individual VWF multimers and on the self-association of individual VWF multimers into larger structures. VWF self-association is accelerated by shear stress. Read more
Stem Cell-Based Human Blood-Brain Barrier Models for Drug Discovery and Delivery
Trends in Biotechnology
The development of novel neuropharmaceuticals requires the evaluation of blood-brain barrier (BBB) permeability and toxicity. Recent studies have highlighted differences in the BBB among different species, with the most important differences involving the expression of P-glycoprotein (P-gp), multidrug resistance-associated proteins, transporters, and claudins.

Federal budget includes targeted boost for the NIH
President Obama revealed his eighth and final
White House budget
on Tuesday, Feb. 9, 2016, outlining plans for spending priorities in fiscal year 2017. In the healthcare realm, the president's budget included few surprises. The budget proposal would give the National Institutes of Health $33.1 billion, a 2.6% increase over 2016. The funding would include $680 million for Vice President Biden's cancer initiative; $100 million more for the Precision Medicine Initiative's 1-million person cohort study; and $45 million in added funds for the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) initiative. Aside from these three targeted programs, all of NIH's 27 institutes and centers except the National Cancer Institute would receive no increase compared to FY2016.
Safety of resorbable vascular scaffolds
The Absorb bioresorbable vascular scaffold (BVS) is on par with a traditional everolimus-eluting stent (EES) when it comes to safety (with the exception of a stronger link to target vessel-related myocardial infarction) a meta-analysis of one-year outcomes has found. As reported in
, recipients of the Absorb BVS and the Xience EES had similar combined rates of mortality, myocardial infarction, and revascularization within 12 months. The authors of the study concluded that "...the aggregate of available evidence supports the safety and effectiveness of BVS at 1 year for treatment of patients with stable coronary artery disease and stabilized acute coronary syndromes."
Vascular growth factors in kidney function
[Bartlett et al. (2016) Annual Review of Physiology] The filtration apparatus of the glomerulus comprises four specialized cell types: fenestrated endothelial cells, podocytes, perivascular mesangial cells, and parietal epithelial cells. A variety of growth factors, notably VEGF, ANGPT, EGF, SEMA3A, TGF-β, and CXCL12, signal in paracrine fashions among these cells to create and maintain filtration barrier function.
Virally-delivered VEGF-A in microsurgically engineered muscle
et al. (2015) Journal of Tissue Engineering]
The authors here report a modification of a published model of tissue engineering, based on an arterio-venous loop encased in a collagen-glycosaminoglycan matrix that serves as an isolated niche for angiogenesis and new tissue formation. A muscular flap harvested from the pectineus muscle was so embedded and transduced by an AAV vector encoding human VEGF-A165. VEGF expression resulted in enhanced tissue formation, with a significant increase in the number of arterioles within the chamber.
