Interaction between nanomaterials and the innate immune system across evolution

Biological Reviews, Volume 98, Issue 3, Page 747-774, June 2023., 2023
ABSTRACT Interaction of engineered nanomaterials (ENMs) with the immune system mainly occurs with cells and molecules of innate immunity, which are present in interface tissues of living organisms. Immuno‐nanotoxicological studies aim at understanding if and when such interaction is inconsequential or may cause irreparable damage. Since innate immunity

THE EXTRACELLULAR RELEASE OF ECHINOCHROME [PDF]

Journal of General Physiology, 1946
A study was made of the diffusion of the red pigment echinochrome from the eggs of the sea urchin, Arbacia punctulata, into sea water. Unfertilized eggs retained their pigment, over periods of hours. Outward diffusion of pigment from unfertilized eggs normally is entirely negligible, or does not occur at all.

Echinochrome A Release by Red Spherule Cells Is an Iron-Withholding Strategy of Sea Urchin Innate Immunity [PDF]

, 2017
Cellular immune defences in sea urchins are shared amongst the coelomocytes – a heterogeneous population of cells residing in the coelomic fluid (blood equivalent) and tissues. The most iconic coelomocyte morphotype is the red spherule cell (or amebocyte)

Pharmacological activity echinochrome a singly and consisting of baa "timarin" [PDF]

Biomeditsinskaya Khimiya, 2012
Pharmacological activity of echinochrome A (EchA) alone and in the biologically active additives (BAA) "Timarin", administered per os has been investigated on volunteers. EchA decreased serum glutatione (GSH) and increased catalase activity 1 h after treatment; catalase activity normalized, while GSH exceeded the initial level 3 h after the treatment ...

Flaviviridae Viruses and Oxidative Stress: Implications for Viral Pathogenesis

Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Oxidative stress is induced once the balance of generation and neutralization of reactive oxygen species (ROS) is broken in the cell, and it plays crucial roles in a variety of natural and diseased processes. Infections of Flaviviridae viruses trigger oxidative stress, which affects both the cellular metabolism and the life cycle of the viruses ...

Effectiveness of Coelatura aegyptiaca Extract Combination with Atorvastatin on Experimentally Induced Hyperlipidemia in Rats

Evidence-Based Complementary and Alternative Medicine, Volume 2019, Issue 1, 2019., 2019
Background. The present study aimed to assess the effectiveness of clam extract in combination with atorvastatin against experimentally hyperlipidemia in rats. Method. Forty male rats were divided into 5 groups (8 rats /group): control, high fat diet (HFD), atorvastatin (AROR), clam extract (CE), and ATOR + CE. Results. The treatments with ATOR and /or

Perturbation of gut bacteria induces a coordinated cellular immune response in the purple sea urchin larva

Immunology &Cell Biology, Volume 94, Issue 9, Page 861-874, October 2016., 2016
The purple sea urchin (Strongylocentrotus purpuratus) genome sequence contains a complex repertoire of genes encoding innate immune recognition proteins and homologs of important vertebrate immune regulatory factors. To characterize how this immune system is deployed within an experimentally tractable, intact animal, we investigate the immune ...
