Intracisternal administration of tanshinone IIA-loaded nanoparticles leads to reduced tissue injury and functional deficits in a porcine model of ischemic stroke.

IBRO Neurosci Rep 2021 Jun 5;10:18-30. Epub 2021 Jan 5.

Regenerative Bioscience Center, University of Georgia, Athens, GA 30602, United States.

Background: The absolute number of new stroke patients is annually increasing and there still remains only a few Food and Drug Administration (FDA) approved treatments with significant limitations available to patients. Tanshinone IIA (Tan IIA) is a promising potential therapeutic for ischemic stroke that has shown success in pre-clinical rodent studies but lead to inconsistent efficacy results in human patients. The physical properties of Tan-IIA, including short half-life and low solubility, suggests that Poly (lactic-co-glycolic acid) (PLGA) nanoparticle-assisted delivery may lead to improve bioavailability and therapeutic efficacy.

Lipid species are known to have various biological functions owing to their structural differences, and each of them possesses a specific role to play depending upon their location and distribution in the cell. Some of these lipids interact with proteins on the cell membrane and acts as second messengers. The level of lipid mediators is generally maintained in the cell by feedback mechanisms; however, their improper degradation or enhanced production leads to their accumulation in the tumor microenvironment and disturbs the homeostasis of the cell.

Neutrophil Extracellular Traps in the Autoimmunity Context.

Front Med (Lausanne) 2021 22;8:614829. Epub 2021 Mar 22.

Laboratory of Molecular Nephrology, Scientific Institute for Research and Health Care, IRCCS Istituto Giannina Gaslini, Genoa, Italy.

The formation of neutrophil extracellular traps (NETs) is a strategy utilized by neutrophils for capturing infective agents. Extracellular traps consist in a physical net made of DNA and intracellular proteins externalized from neutrophils, where bacteria and viruses are entrapped and killed by proteolysis. A complex series of events contributes to achieving NET formation: signaling from infectious triggers comes first, followed by decondensation of chromatin and extrusion of the nucleosome components (DNA, histones) from the nucleus and, after cell membrane breakdown, outside the cell.

Single Cell Transcriptome Data Analysis Defines the Heterogeneity of Peripheral Nerve Cells in Homeostasis and Regeneration.

Front Cell Neurosci 2021 22;15:624826. Epub 2021 Mar 22.

Faculty of Health, Peninsula Medical School, University of Plymouth, Plymouth, United Kingdom.

The advances in single-cell RNA sequencing technologies and the development of bioinformatics pipelines enable us to more accurately define the heterogeneity of cell types in a selected tissue. In this report, we re-analyzed recently published single-cell RNA sequencing data sets and provide a rationale to redefine the heterogeneity of cells in both intact and injured mouse peripheral nerves. Our analysis showed that, in both intact and injured peripheral nerves, cells could be functionally classified into four categories: Schwann cells, nerve fibroblasts, immune cells, and cells associated with blood vessels.

Intrabone infusion for allogeneic umbilical cord blood transplantation in children.

Bone Marrow Transplant 2021 Apr 6. Epub 2021 Apr 6.

Cell Therapy and Transplant Program, Division of Hematology-Oncology, Ste-Justine University Hospital Center, Montreal, QC, Canada.

Umbilical cord blood transplantation (UCBT) has been used to treat malignant and non-malignant diseases. UCBT offers the advantages of easy procurement and acceptable partial HLA mismatches, but also shows delayed hematopoietic and immunological recoveries. We postulated that an intrabone (IB) infusion of cord blood could provide a faster short- and long-term engraftment in a pediatric population with malignant and non-malignant hematologic diseases.

Inhibition of the Lipoxin A4 and Resolvin D1 Receptor Impairs Host Response to Acute Lung Injury Caused by Pneumococcal Pneumonia in Mice.

Am J Physiol Lung Cell Mol Physiol 2021 Apr 6. Epub 2021 Apr 6.

Cardiovascular Research Institute, University of California, San Francisco, United States.

Resolution of the acute respiratory distress syndrome (ARDS) from pneumonia requires repair of the injured lung endothelium and alveolar epithelium, removal of neutrophils from the distal airspaces of the lung, and clearance of the pathogen. Previous studies have demonstrated the importance of specialized pro-resolving mediators (SPMs) in the regulation of host responses during inflammation. Although ARDS is commonly caused by Streptococcus pneumoniae, the role of Lipoxin A4 (LXA4) and Resolvin D1 (RvD1) in pneumococcal pneumonia is not well understood. Read More

Review: The Emerging Role of Neutrophil Extracellular Traps in Sepsis and Sepsis-Associated Thrombosis.

Front Cell Infect Microbiol 2021 17;11:653228. Epub 2021 Mar 17.

Department of Anesthesiology, Zhongshan Hospital, Fudan University, Shanghai, China.

Patients with sepsis commonly suffer from coagulation dysfunction and lead to the formation of thrombus. During the development of sepsis, neutrophils migrate from the circulating blood to infected tissues and mediate the formation of neutrophil extracellular traps (NETs) that kill pathogens. However, the overactivation of neutrophils can promote the formation of immunothrombosis and even cause disseminated intravascular coagulation (DIC), which damages microcirculation. Read More

Department of Pharmacology and Toxicology, Michigan State University, East Lansing, MI, United States.

Perivascular adipose tissue (PVAT) may connect adiposity to hypertension because of its vasoactive functions and proximity to blood vessels.

Microbiota profiling in aging-associated inflammation and liver degeneration.

Int J Med Microbiol 2021 Mar 29;311(4):151500. Epub 2021 Mar 29.

Department of Nutritional Sciences, Molecular Nutritional Science, University of Vienna, Vienna, Austria. Electronic address:

Background: The number of people above the age of 60 years is raising world-wide being associated with an increase in the prevalence of aging-associated impairments and even diseases. Recent studies suggest that aging is associated with alterations in bacterial endotoxin levels and that these changes may add to low-grade inflammation, the so-called 'inflammaging', and aging-associated liver degeneration. However, mechanisms involved, and especially, the interaction of intestinal microbiota and barrier in the development of aging-associated inflammation and liver degeneration have not been fully understood.
