Sterile inflammation after injury is important for tissue restoration. In injured human and mouse tissues, macrophages were recently found to accumulate perivascularly. This study investigates if macrophages adopt a mural cell phenotype important for restoration after ischemic injury.

However, their further development under the pharmaceutical regulatory framework is hindered by poor understanding of the mechanisms by which they exert their effects. In the current study the interaction of MSPs with the lipid digestion process is investigated, specifically interactions with lipase enzymes and lipid digestion products as a key contributing factor to lipid absorption and calorific intake.

An open-label, single-arm, multicenter trial was conducted in which SiPore15 was consumed three times daily for 12 weeks. Hemoglobin A1c (HbA1c, primary end point) and an array of metabolic parameters were measured at baseline and throughout the trial.

VEGF-A expression has also been found to recruit myeloid cells to ischemic tissues where they contribute to angiogenesis. This study investigates the mechanisms underlying neutrophil recruitment to VEGF-A as well as the characteristics of these neutrophils.
