Pathogenic bacteria trigger complex molecular interactions in hosts that are characterized mainly by an increase reactive oxygen species (ROS) as well inflammation-associated response. To counteract oxidative damage, cells respond through protective mechanisms to promote resistance and avoid tissue damage infection; among these cellular the activation or inhibition of nuclear factor E2-related 2 (Nrf2) is frequently observed. The transcription Nrf2 considered master regulator several hundred cytoprotective antioxidant genes. Under normal conditions, Keap1/Nrf2 signaling protects environment sensing deleterious radicals inducing expression genes coding for proteins intended neutralize harmful effects ROS.

Oxidative stress plays an essential role in neurodegenerative pathophysiology, acting as both a critical signaling mediator and driver of neuronal damage. Hydrogen sulfide (H2S), versatile gasotransmitter, exhibits similarly “Janus-faced” nature, potent antioxidant cytoprotective molecule at physiological concentrations, but becoming detrimental when dysregulated. This review explores the dual roles oxidative H2S normal cellular physiology focusing on disease progression. We highlight potential therapeutic opportunities for targeting redox sulfur-based systems diseases by elucidating intricate balance between these opposing forces.

Photodynamic therapy (PDT) is an innovative treatment that has recently been approved for clinical use and holds promise cancer patients. It offers several benefits, such as low systemic toxicity, minimal invasiveness, the ability to stimulate antitumor immune responses. For certain types of cancer, it shown positive results with few side effects. However, PDT still faces some challenges, including limited light penetration into deeper tumor tissues, uneven distribution photosensitizer (PS) can also affect healthy cells, difficulties posed by hypoxic microenvironment (TME). In conditions, PDT's effectiveness reduced due insufficient production reactive oxygen species, which limits destruction lead relapse. This review highlights recent advances in photosensitizers nanotechnologies are being developed improve PDT. focuses on multifunctional nanoplatforms nanoshuttles have preclinical studies, especially treating solid tumors. One key areas focus development PSs specifically target mitochondria treat deep-seated malignant New mitochondria-targeting nano-PSs designed better water solubility extended wavelength ranges, allowing them tumors more effectively, even challenging, environments. These advancements opening new doors treatment, when combined other therapeutic strategies. Moving forward, research should optimizing PDT, creating efficient drug delivery systems, developing smarter platforms. Ultimately, these efforts aim make a first-choice option

ABSTRACT Cryptococcus neoformans is a common fungal pathogen, causing fatal meningoencephalitis in immunocompromised individuals. The limited availability of antifungals and increasing resistance pathogens including C. emphasize the need to find new drugs. Mitochondria have long been associated with drug fungi. They are connected endoplasmic reticulum (ER) via multiprotein complex, ER–mitochondria encounter structure (ERMES), which unique kingdom. In this study on neoformans, four subunits ERMES namely, Mmm1, Mdm12, Mdm10 Mdm34, were deleted generate strains Δmmm1, Δmdm12, Δmdm10 Δmdm34, respectively. These mutants had impaired mitochondria sensitive antifungals, echinocandins, due lower chitin content. Virulence factors, capsule formation melanin production, debilitated mutants. partner organelle ER was also affected by compromised contact, as activity several ER-synthesized enzymes involved virulence impacted. vivo studies Caenorhabditis elegans model cryptococcosis confirmed reduced results indicate that impairment complex crucial for pathogenesis neoformans.

Fungal keratitis is a severe vision-threatening corneal infection with prognosis influenced by fungal virulence and the host's immune defense mechanisms. However, there still lack of effective drugs that attenuate while relieving inflammatory response caused keratitis. Finding an treatment to solve these problems particularly important. We synthesized Zeolitic imidazolate framework-90 (ZIF-90) water-based synthesis method characterized it. In vitro experiments included mycelium electron microscopy, Cell Counting Kit-8 (CCK-8), Enzyme-linked immunosorbent assay (ELISA). These trials verified disruptive effects ZIF-90 on morphology, cell membrane, wall, biofilm formation Aspergillus fumigatus (A. fumigatus). also demonstrated impact proinflammatory cytokines tumor necrosis factor-α (TNF-α) interleukin-6 (IL-6). Moreover, effect mitochondrial reactive oxygen species (mtROS) cells fungi was MitoSOX Red Mitochondrial Superoxide Indicator (MitoSOX). vivo, toxicity test, establishment mycotic mouse model, immunofluorescence staining were used evaluate efficacy in procedure addition, investigate whether metal-ligand zinc organic ligand imidazole acted as essential factors ZIF-90, we investigated antimicrobial anti-inflammatory ZIF-8, ZIF-67 Metal-Organic Frameworks-74 (Zn) (MOF-74 (Zn)) Minimum Inhibitory Concentration (MIC) ELISA experiments. has therapeutic keratitis, which could break protective organelles A. fumigatus, such wall. can be targeted increase amount mtROS promote apoptosis macrophages. The results both ions possessed effects. exhibited better antifungal properties than ZIF-67, MOF-74 (Zn).

Research on bioactive compounds has grown recently due to their health benefits and limited adverse effects, particularly in reducing the risk of chronic diseases, including neurodegenerative conditions. According these observations, this study investigates activity sulforaphane (RS-GRA) an vitro model differentiated NSC-34 cells. We performed a transcriptomic analysis at various time points (24 h, 48 72 h) RS-GRA concentrations (1 µM, 5 10 µM) identify molecular pathways influenced by compound effects dosage prolonged exposure. found 39 differentially expressed genes consistently up- or downregulated across all Notably, Nfe2l2, Slc1a5, Slc7a11, Slc6a9, Slc6a5, Sod1, Sod2 were upregulated, while Ripk1, Glul, Ripk3, Mlkl downregulated. Pathway perturbation showed that overall dysregulation results significant increase redox pathway (adjusted p-value 1.11 × 10−3) inhibition necroptosis 4.64 10−3). These findings suggest RS-GRA’s potential as adjuvant disease treatment, both increased may be beneficial context. Furthermore, our data two possible administration strategies, namely acute approach with higher dosages lower dosages.
