Atopic dermatitis (AD) is a chronic inflammatory skin disorder marked by thickening, severe pruritus, lesions, and emotional disturbances, including anxiety depression-like behavior. Current treatments primarily rely on localized therapies, which can lead to adverse effects such as hyperglycemia Cushing's syndrome with repeated use. To address these issues, we developed hyaluronic acid-based separable microneedle patch (Dic@pCu-HA MN), integrating polydopamine-coordinated copper-based metal-organic frameworks (pCu-MOFs) the anti-inflammatory agent dictamnine (Dic), for synergistic management of AD its neuropsychiatric comorbidities. pCu-MOFs exhibited dual functionality nanocargo hydrophobic Dic (encapsulation efficiency: 84.62 ± 2.14%) multienzyme mimics that efficiently scavenge reactive oxygen species (ROS) (superoxide radical scavenging: 63.85 0.34%). In vitro release studies demonstrated ROS-responsive 86.80 4.83% over 48 h under pathology-mimicking conditions. 1-Chloro-2,4-dinitrochlorobenzene (DNCB)-induced mouse model, Dic@pCu-HA MN significantly reduced oxidative stress (8-OHdG: 85.1 7.0% decrease), suppressed pro-inflammatory cytokines (IL-4: 70.0 7.8% decrease vs control), restored barrier integrity. By modulating HPA axis, system attenuated neuroinflammation alleviated itching (scratching frequency: 40.1 41.3% reduction) behavior (time in bright box: 96.6 156.2% increase). This combined therapeutic approach not only offers comprehensive strategy but also provides potential benefits addressing disorders their sequelae.

Immunogenic cell death (ICD) is a promising cancer therapy where dying tumor cells release damage-associated molecular patterns (DAMPs) to activate immune responses. Recent research highlights the critical role of metabolic reprogramming in cells, including Warburg effect, oxidative stress, and lipid metabolism, modulating ICD shaping microenvironment. These changes enhance activation, making tumors more susceptible surveillance. This review explores mechanisms linking mitochondrial endoplasmic reticulum (ER) ferroptosis. It also discusses innovative therapeutic strategies, such as personalized combination therapies, inhibitors, targeted delivery systems, improve efficacy. The future immunotherapy lies integrating activation overcome evasion, with multi-omics approaches microbiome modulation offering new avenues for enhanced treatment outcomes.
