[PMID: 39098373 DOI: 10.1016/j.jdermsci.2024.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 06/21/2024] [Accepted: 07/23/2024] [Indexed: 08/06/2024]
Abstract
BACKGROUND Ischemia- reperfusion (I/R) injury-induced oxidative stress is a key factor in the pathogenesis of pressure ulcer formation. Ferroptosis is an iron-dependent programmed cell death that connects oxidative stress and inflammation in various diseases. Recent studies revealed the protective effect of inhibition of ferroptosis in I/R injury. However, the role of ferroptosis in cutaneous I/R injury remains elusive. OBJECTIVE To assess the role of ferroptosis in the progression of cutaneous I/R injury. METHODS Cutaneous I/R injury experiments and histopathological studies were performed in wild-type mice with or without exposure to volatile ferroptosis inhibitor, TEMPO (2,2,6,6-Tetramethylpiperidine-1-oxyl). The suppressive effects of TEMPO on ferroptosis inducing cell death and oxidative stress were examined in vitro. RESULTS Inhibition of ferroptosis with TEMPO significantly reduced ulcer formation after cutaneous I/R injury. Fluctuated ferroptosis markers, such as GPX4, ACSL4, and 4-HNE expression in the I/R skin site, were reversed by TEMPO treatment. Inhibition of ferroptosis reduced apoptosis, CD3+ infiltrating lymphocytes, and improved vascularity in the I/R skin site. Inhibition of ferroptosis also suppressed the enhancement of Nrf2 activation. In vitro, ferroptosis and the activation of ferroptosis-related gene expression by RSL3 stimulation were markedly ameliorated by TEMPO treatment in mouse fibroblasts. Inhibiting ferroptosis also suppressed the elevation of the mRNA levels of NOX2 and HO-1 caused by ferroptosis. CONCLUSION Cutaneous I/R injury-induced ferroptosis likely promotes cell death, vascular loss, infiltration of inflammatory cells, and oxidative stress. The inhibition of ferroptosis with TEMPO might have potential clinical application as novel therapeutic agent for cutaneous I/R injury.

Abstract
Type 2 diabetes (T2D) is a heterogenous disease, and conventionally, peripheral insulin resistance (IR) was thought to precede islet β-cell dysfunction, promoting progression from prediabetes to T2D. New evidence suggests that T2D-lean individuals experience early β-cell dysfunction without significant IR. Regardless of the primary event (i.e., IR vs. β-cell dysfunction) that contributes to dysglycemia, significant early-onset oxidative damage and mitochondrial dysfunction in multiple metabolic tissues may be a driver of T2D onset and progression. Oxidative stress, defined as the generation of reactive oxygen species (ROS), is mediated by hyperglycemia alone or in combination with lipids. Physiological oxidative stress promotes inter-tissue communication, while pathological oxidative stress promotes inter-tissue mis-communication, and new evidence suggests that this is mediated via extracellular vesicles (EVs), including mitochondria containing EVs. Under metabolic-related stress conditions, EV-mediated cross-talk between β-cells and skeletal muscle likely trigger mitochondrial anomalies leading to prediabetes and T2D. This article reviews the underlying molecular mechanisms in ROS-related pathogenesis of prediabetes, including mitophagy and mitochondrial dynamics due to oxidative stress. Further, this review will describe the potential of various therapeutic avenues for attenuating oxidative damage, reversing prediabetes and preventing progression to T2D.

Abstract
Hematopoietic stem progenitor cells (HSPCs) follow the diurnal circulation rhythm in peripheral blood (PB) with nadir during late night and peak at early morning hours. The level of these cells in PB correlates with activation of innate immunity pathways, including complement cascade (ComC) that drives activation of Nlrp3 inflammasome. To support this, mice both in defective ComC activation as well as Nlrp3 inflammasome do not show typical changes in the diurnal level of circulating HSPCs. Migration of HSPCs is also impaired at the intracellular level by the anti-inflammatory enzyme heme oxygenase-1 (HO-1) which is an inhibitor of Nlrp3 inflammasome. It is also well known that circadian rhythm mediates PB level of melatonin released from the pineal gland. Since trafficking of HSPCs is driven by innate immunity-induced sterile inflammation and melatonin has an anti-inflammatory effect, we hypothesized that melatonin could negatively impact the release of HSPCs from BM into PB by inhibiting Nlrp3 inflammasome activation. We provide an evidence that melatonin being a ''sleep regulating pineal hormone'' directly inhibits migration of HSPCs both in vitro migration assays and in vivo during pharmacological mobilization. This correlated with inhibition of cholesterol synthesis required for a proper membrane lipid raft (MLRs) formation and an increase in expression of HO-1-an inhibitor of Nlrp3 inflammasome. Since melatonin is a commonly used drug, this should be considered while preparing a patient for the procedure of HSPCs mobilization. More importantly, our studies shed more mechanistic light on a role of melatonin in the diurnal circulation of HSPCs.

Abstract
Chemoresistance often complicates the management of cancer, as noted in the instance of acute myeloid leukemia (AML). Mitochondrial function is considered important for the viability of AML blasts and appears to also modulate chemoresistance. As mitochondrial metabolism is aberrant in AML, any distinct pathways could be directly targeted to impact both cell viability and chemoresistance. Therefore, identifying and targeting those precise rogue elements of mitochondrial metabolism could be a valid therapeutic strategy in leukemia. Here, we review the evidence for abnormalities in mitochondria metabolic processes in AML cells, that likely impact chemoresistance. We further address several therapeutic approaches targeting isocitrate dehydrogenase 2 (IDH2), CD39, nicotinamide phosphoribosyl transferase (NAMPT), electron transport chain (ETC) complex in AML and also consider the roles of mesenchymal stromal cells. We propose the term "mitotherapy" to collectively refer to such regimens that attempt to override mitochondria-mediated metabolic reprogramming, as used by cancer cells. Mounting evidence suggests that mitotherapy could provide a complementary strategy to overcome chemoresistance in liquid cancers, as well as in solid tumors.

Abstract
Hematopoiesis is regulated by several mediators such as peptide-based growth factors, cytokines, and chemokines, whose biological effects have been studied for many years. However, several other mediators have been identified recently that affect the fate of hematopoietic stem/progenitor cells (HSPC) as well as non-hematopoietic cells in the bone marrow microenvironment. These new mediators comprise members of purinergic signaling pathways and are active mediators of the soluble arm of innate immunity, the complement cascade (ComC). In this review, we will discuss the coordinated effects of these pathways in regulating the biology of HSPC. Importantly, both purinergic signaling and the ComC are activated in stress situations and interact with specific receptors expressed on HSPC. Evidence has accumulated indicating that some of the purinergic as well as ComC receptors could also be activated intracellularly by intrinsically expressed ligands. To support this recent evidence, our work indicates that the major mediator of purinergic signaling, adenosine triphosphate, and the cleavage product of the fifth component of the ComC (C5), C5a anaphylatoxin, can activate their corresponding receptors expressed on the outer mitochondrial membrane in an autocrine manner. We will also discuss recent evidence that these responses, mediated by purinergic signaling and the ComC network, are coordinated by activation of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 2 - reactive oxygen species - NLR family pyrin domain containing 3 (NLRP3) inflammasome (Nox2-ROS-NLRP3) axis.

Abstract
Hematopoietic stem/progenitor cells (HSPCs) express receptors for complement cascade (ComC) cleavage fragments C3a and C5a and may respond to inflammation-related cues by sensing pathogen-associated molecular pattern molecules (PAMPs) released by pathogens as well as non-infectious danger associated molecular pattern molecules (DAMPs) or alarmin generated during stress/tissue damage sterile inflammation. To facilitate this HSPCs are equipped with C3a and C5a receptors, C3aR and C5aR, respectively, and express on the outer cell membrane and in cytosol pattern recognition receptors (PPRs) that sense PAMPs and DAMPs. Overall, danger-sensing mechanisms in HSPCs mimic those seen in immune cells, which should not surprise as hematopoiesis and the immune system develop from the same common stem cell precursor. This review will focus on the role of ComC-derived C3a and C5a that trigger nitric oxide synthetase-2 (Nox2) complex to release reactive oxygen species (ROS) that activate important cytosolic PRRs-Nlrp3 inflammasome, which orchestrates responsiveness of HSPCs to stress. Moreover, recent data indicate that in addition to circulating in peripheral blood (PB) activated liver-derived ComC proteins, a similar role plays ComC expressed and intrinsically activated in HSPCs known as "complosome". We postulate that ComC triggered Nox2-ROS-Nlrp3 inflammasome responses, if they occur within non-toxic to cells' "hormetic range of activation", positively regulate HSCs migration, metabolism, and proliferation. This sheds a new light on the immune-metabolic regulation of hematopoiesis.
