Quantitative conformational profiling of kinase inhibitors reveals origins of selectivity for Aurora kinase activation states.

Proc Natl Acad Sci U S A 2018 Dec 5. Epub 2018 Dec 5.

Department of Pharmacology, University of Minnesota, Minneapolis, MN 55455;

Protein kinases undergo large-scale structural changes that tightly regulate function and control recognition by small-molecule inhibitors. Methods for quantifying the conformational effects of inhibitors and linking them to an understanding of selectivity patterns have long been elusive. We have developed an ultrafast time-resolved fluorescence methodology that tracks structural movements of the kinase activation loop in solution with angstrom-level precision, and can resolve multiple structural states and quantify conformational shifts between states.

GVHD: biology matters.

Hematology Am Soc Hematol Educ Program 2018 Nov;2018(1):221-227

The Tisch Cancer Institute and Division of Hematology/Medical Oncology, The Icahn School of Medicine at Mount Sinai Hospital, New York, NY.

Acute graft-versus-host disease (GVHD) targets the crypts in the gastrointestinal (GI) tract that are responsible for the self-renewal of the intestinal mucosa. Recent advances in the identification and culture of intestinal stem cells have improved our understanding of the interactions between the microbiome and the immune system (both innate and adaptive) that are key to the pathophysiology of GVHD. The identification of serum biomarkers that best predict long-term GVHD outcomes derive from the GI tract and have focused attention on cellular elements that act as shields against GVHD as well as its targets.

This latter was traditionally split between expensive drugs in narrow indications (targeted treatments, orphan diseases) and drugs addressing a wider population at moderate costs, at least not commensurate with that of contemporary innovations. Even if these prices - resulting in from an undisputable financialization of advanced medical research - raise a legitimate emotion among health care professionals and in the public opinion, even if regulators impose price cuts, at least in Europe, these treatments - that can be «efficient» in a health economic sense - raise serious funding problems.

Sulfated archaeol glycolipids: Comparison with other immunological adjuvants in mice.

PLoS One 2018 4;13(12):e0208067. Epub 2018 Dec 4.

National Research Council Canada, Ottawa, Ontario, Canada.

Archaeosomes are liposomes traditionally comprised of total polar lipids (TPL) or semi-synthetic glycerolipids of ether-linked isoprenoid phytanyl cores with varied glyco- and amino-head groups. As adjuvants, they induce robust, long-lasting humoral and cell-mediated immune responses and enhance protection in murine models of infectious disease and cancer. Traditional total polar lipid (TPL) archaeosome formulations are relatively complex and first generation semi-synthetic archaeosomes involve many synthetic steps to arrive at the final desired glycolipid composition.
