Recent advances have greatly improved our understanding of the molecular mechanisms behind atherosclerosis pathogenesis. However, there is still a need to systematize this data from general pathology perspective, particularly with regard atherogenesis patterns in context both canonical and non-classical inflammation types. In review, we analyze various typical phenomena outcomes cellular pro-inflammatory stress atherosclerosis, as well role endothelial dysfunction local systemic manifestations low-grade inflammation. We also present features immune development productive stable unstable plaques, along their similarities differences compared There are numerous factors that act inducers inflammatory process including vascular endothelium aging, metabolic dysfunctions, autoimmune, some cases, infectious damage factors. Life-critical complications such cardiogenic shock severe strokes, associated acute hyperinflammation. Additionally, critical atherosclerotic ischemia lower extremities induces paracoagulation chronic Conversely, sepsis, other conditions, diseases contribute atherogenesis. summary, can be characterized an independent form inflammation, sharing but having fundamental variants (classic vasculitis).

Pro-inflammatory stress is inherent in any cells that are subject to damage or threat of damage. It defined by a number universal components, including oxidative stress, cellular response DNA damage, unfolded protein mitochondrial and endoplasmic reticulum changes autophagy, inflammasome formation, non-coding RNA response, formation an inducible network signaling pathways, epigenetic changes. The presence receptor secretory phenotype many the cause tissue pro-inflammatory stress. key phenomenon determining occurrence classical inflammatory focus microvascular (exudation, leukocyte migration alteration zone). This same reaction at systemic level leads development life-critical inflammation. From this standpoint, we can characterize common mechanisms pathologies differ their clinical appearance. division inflammation into alternative variants has deep evolutionary roots.

A Dual Heat Shock Protein Down‐Regulation Strategy Using PDA/Cu/ICG/R Controlled by NIR “Switch” Enhances Mild‐Photothermal Therapy Effect

Advanced Healthcare Materials, Год журнала: 2023, Номер 12(27)

Опубликована: Июнь 10, 2023

The purpose of this study is to down-regulate heat shock proteins and improve the mild photothermal therapy (mild-PTT) effect polydopamine (PDA) by preparing nanosystem Cu2+ indocyanine green (ICG)-loaded PDA nanospheres with surface modification integrin-targeted cyclic peptide (cRGD) (PDA/Cu/ICG/R), which can limit ATP synthesis through double mitochondrial destruction pathway. In vitro in vivo experiments using PDA/Cu/ICG/R irradiated an NIR laser demonstrate that when "OFF," undergo Fenton-like reaction tumor cells, producing a large amount hydroxyl radicals (·OH), leads oxidative stress cells. This cause phosphorylation dysfunction, resulting limited synthesis. When "ON," mild-PTT accelerate produce ·OH. Simultaneously, activate ICG reactive oxygen species (ROS) storm, amplify intracellular stress, continuously damage mitochondria. biodegradability greatly reduces risk toxicity caused long-term retention organisms. Finally, improvement successfully achieved pathway controlled "switch."

Can heat shock protein 70 (HSP70) serve as biomarkers in Antarctica for future ocean acidification, warming and salinity stress?

Polar Biology, Год журнала: 2022, Номер 45(3), С. 371 - 394

Опубликована: Янв. 24, 2022

Abstract The Antarctic Peninsula is one of the fastest-warming places on Earth. Elevated sea water temperatures cause glacier and ice melting. When icebergs melt into ocean, it “freshens” saltwater around them, reducing its salinity. oceans absorb excess anthropogenic carbon dioxide (CO 2 ) causing decline in ocean pH, a process known as acidification. Many marine organisms are specifically affected by warming, freshening Due to sensitivity Antarctica global using biomarkers best way for scientists predict more accurately future climate change provide useful information or ecological risk assessments. 70-kilodalton (kDa) heat shock protein (HSP70) chaperones have been used stress temperate tropical environments. induction HSP70 genes ( Hsp70 that alter intracellular proteins living signal triggered environmental temperature changes. Induction has observed both eukaryotes prokaryotes response stressors including increased decreased temperature, salinity, pH combined effects changes acidification salinity stress. Generally, HSP70s play critical roles numerous complex processes metabolism; their synthesis can usually be during stressful conditions. However, there question whether may serve excellent considering long residence time cold polar environment which appears greatly modified responding transcriptional systems. This review provides insight vital make them ideal candidates identifying resistance resilience abiotic associated with change, organisms.
