How to accurately diagnose and treat bacterial infections in vivo remains a huge challenge. Therefore, we have developed targeted delivery nanosystem by coextruding the pretreated macrophage membrane of S. aureus with carbon dots (M@CD). The M@CD demonstrates potent antibacterial effects both vitro through generation reactive oxygen species (ROS). Furthermore, exhibits enhanced targeting ability stable fluorescence properties, addressing issues such as poor efficiency high immunogenicity vivo. This innovative approach enables infection site specific aggregation elimination infections, thereby providing promising strategy for integrated diagnosis, treatment, monitoring infections.

The innate immune system's inactivation and microbial biofilm-induced antibiotic resistance are the main causes of implant-associated infections (IAIs), which frequently result in implant surgical failure. Refractory recolonization is consequence standard therapies that unable to consistently suppress escaping planktonic bacteria from biofilm, thereby enabling IAIs thrive. Here, we specifically designed a macrophage-like biomimetic nanoparticle (F/R@PM) for biofilm microenvironment (BME), was fabricated by coating cell membrane derived macrophage onto poly (lactic-co-glycolic acid) (PLGA) namoparticles (NPs) loaded with FOT (NO donor) R837 (TLR7 agonist). After injecting F/R@PM into mice infections, it able selectively target macrophages through proteins on its surface effectively release R837. Then, spreads outside could react glutathione (GSH) BEM rapidly produce large amount NO inside biofilms destroy kill bacteria. At same time, would encourage scavenge had escaped disintegration improved phagocytosis. Overall, this work shows treatment immunotherapy together have promising potential long-term efficient control eradication IAIs.

Macrophages, as highly phenotypic plastic immune cells, play diverse roles in different pathological conditions. Changing and controlling the phenotypes of macrophages is considered a novel potential therapeutic intervention. Meanwhile, specific transmembrane proteins anchoring on surface macrophage membrane are relatively conserved, supporting its functional properties, such inflammatory chemotaxis tumor targeting. Thus, series drug delivery systems related to commonly used treat chronic diseases. This review summarizes macrophages-based strategies for diseases, discusses regulation their polarization processes, presents how design apply site-specific targeted vivo based derived receptors. It aims provide better understanding immunoregulation proposes approaches

Small-interfering RNAs (siRNAs) offer promising prospects for treating pyroptosis-related autoimmune diseases. However, poor stability and off-target effects during in vivo transportation hinder their practical clinical applications. Precision delivery adaptive release of siRNAs into inflamed tissues immune cells could unleash full therapeutic potential. This study establishes a pyroptotic-spatiotemporally selective siRNA system (PMRC@siGSDME) that selectively targets inflammatory tissues, responds to pyroptosis, exhibits remarkable efficacy against various Novel hybrid nanovesicles (NVs) are designed as combination pyroptotic macrophage membranes (PMs) R8-cardiolipin-containing (RC-NVs). Evidence provides PM-derived proteins involved cell-cell interactions membrane trafficking may contribute the specificity NVs tissue. In addition, cardiolipin anchored increases its affinity activated gasdermin E (GSDME) achieves pyroptosis-adaptive siGSDME spatiotemporally suppression responses. More importantly, PMRC@siGSDME displays significant anti-inflammatory multiple mouse disease models, including arthritis bowel (IBD). Collectively, an innovative strategy precisely tailored has been developed, paving way new treatments diseases with minimal side wide applicability.

Abstract Volumetric muscle loss (VML) is a severe form of trauma that exceeds the regenerative capacity skeletal tissue, leading to substantial functional impairment. The abnormal immune response and excessive reactive oxygen species (ROS) accumulation hinder regeneration following VML. Here, an interfacial cross‐linked hydrogel‐poly(ε‐caprolactone) nanofiber composite, incorporates both biophysical biochemical cues modulate ROS microenvironment for enhanced VML repair, engineered. cross‐linking achieved through Michael addition between catechol thiol groups. resultant composite exhibits mechanical strength without sacrificing porosity. Moreover, it mitigates oxidative stress promotes macrophage polarization toward pro‐regenerative phenotype, in vitro mouse model. 4 weeks post‐implantation, mice implanted with show improved grip walking performance, along increased fiber diameter, angiogenesis, more nerve innervation compared control mice. Collectively, these results suggest nanofiber‐hydrogel could serve as cell‐free drug‐free strategy augmenting by modulating at site.
