A noteworthy amplification in the occurrences of bone-related afflictions has emerged in conjunction with the aging global population. Macrophages, essential elements within the innate and adaptive immune frameworks, play a vital role in sustaining bone equilibrium and fostering bone growth. Small extracellular vesicles (sEVs) have drawn heightened attention due to their function in cellular communication in diseased microenvironments and their suitability as drug delivery systems. A considerable amount of recent research has broadened our understanding of how macrophage-derived small extracellular vesicles (M-sEVs) affect bone disorders through different polarization states and their biological functionalities. We comprehensively analyze the application and operational principles of M-sEVs in bone diseases and drug delivery in this review, which could potentially furnish innovative approaches to the diagnosis and treatment of human bone disorders, including osteoporosis, arthritis, osteolysis, and bone defects.
As an invertebrate, the crayfish's defense mechanism against external pathogens is exclusively an innate immune system response. From red swamp crayfish, Procambarus clarkii, a single Reeler domain molecule, designated PcReeler, was identified in this study. Gill tissue exhibited a substantial expression of PcReeler, as ascertained through tissue distribution analysis, and this expression was boosted by bacterial stimulation. Dampening the expression of PcReeler through RNA interference methodology exhibited a notable enhancement in bacterial numbers within crayfish gills, coupled with a noteworthy increase in crayfish mortality rates. Through 16S rDNA high-throughput sequencing, the silencing of PcReeler was shown to be a factor in altering gill microbiota stability. The recombinant PcReeler protein demonstrated the capability of binding to microbial polysaccharides and bacteria, effectively preventing biofilm formation. Evidence from these results unambiguously demonstrates PcReeler's function within the antibacterial immune system of P. clarkii.
