Abstract Several drugs can be used for treating inflammatory skin pathologies like dermatitis and psoriasis. However, the management of chronic long-term cases, topical administration is preferred over oral delivery since it prevents certain issues due to systemic side effects from occurring. Cyclosporin A (CsA) has been this purpose; however, its high molecular weight (1202 Da) restricts diffusion through structure. Here, we developed a nano-in-micro device combining lipid vesicles (LVs) dissolving microneedle array patches (DMAPs) targeted delivery. CsA-LVs allowed effective incorporation CsA in hydrophilic DMAP matrix despite hydrophobicity drug. Polymeric composed poly (vinyl alcohol) (5% w/v), pyrrolidine) (15% w/v) CsA-LV dispersion (10% v/v) led formation CsA-LVs@DMAPs with adequate mechanical properties penetrate stratum corneum barrier.

The extracellular matrix (ECM) is a 3-dimensional structure and an essential component in all human tissues. It comprised of varying proteins, including collagens, elastin, smaller quantities structural proteins. Studies have demonstrated the ECM aids cellular adherence, tissue anchoring, signaling, recruitment cells. During times integumentary injury or damage, either acute chronic, damaged. Through series overlapping events called wound healing phases—hemostasis, inflammation, proliferation, remodeling—the synthesized ideally returned to its native state.

Short-chain fatty acids (SCFAs) are metabolites of gut microbes that can modulate the host inflammatory response, and contribute to health homeostasis. Since introduction gut-skin axis concept, link between SCFAs skin diseases has attracted considerable attention. In this review, we have summarized literature on role in inflammation, correlation diseases, especially atopic dermatitis, urticaria, psoriasis. Studies show signaling factors alleviate inflammation. The information presented review provides new insights into molecular mechanisms driving regulation, along with possible pathways be targeted for treatment prevention diseases.

Wound healing in cases of excessive inflammation poses a significant challenge due to compromised neovascularization. Here, we propose multi-functional composite hydrogel engineered overcome such conditions through recruitment and activation macrophages with adapted degradation the hydrogel. The (G-TSrP) is created by combining gelatin methacryloyl (GelMA) nanoparticles (TSrP) composed tannic acid (TA) Sr2+. These are prepared using one-step mineralization process assisted metal-phenolic network formation. G-TSrP exhibits ability eliminate reactive oxygen species direct polarization toward M2 phenotype. It has been observed that liberation TA Sr2+ from actively facilitate up-regulation expression extracellular matrix remodeling genes macrophages, thereby, coordinate vivo G-TSrP.

Abstract The absence of a clear consensus on the definition and significance fascia indiscriminate use term throughout clinical scientific literature has led to skepticism regarding its importance in human body. To address this challenge, we propose that: (1) fasciae, fascial interstitia within them, constitute an anatomical system, defined as layered body‐wide multiscale network connective tissue that allows tensional loading shearing mobility along interfaces; (2) system comprises four organs: superficial fascia, musculoskeletal (deep) visceral neural fascia; (3) these organs are further composed structures, some which eponymous; (4) all their structural components contain variable combinations arrangements classically tissues: epithelial, connective, muscle, neural; (5) overarching functions arise from contrasting biomechanical properties two basic types layers distributed system: one predominantly collagenous relatively stiff, other rich hyaluronic acid viscous, allowing for free flow fluid; (6) topographical organization different locations is related local variations function (e.g. unidirectional favor loading, interwoven structures shear mobility) thereby accounting both system's universal functional aspects site‐specific between them.
