Abstract
The skin, serving as the body's outermost layer, boasts a vast area and intricate structure, functioning as the primary barrier against external threats. Disruptions in the composition and functionality of the skin can lead to a diverse array of skin conditions, such as wounds, burns, and diabetic ulcers, along with inflammatory disorders, infections, and various types of skin cancer. These disorders not only exacerbate concerns regarding skin health and beauty but also have a significant impact on mental well-being. Due to the complexity of these disorders, conventional treatments often prove insufficient, necessitating the exploration of new therapeutic approaches. Researchers develop new therapies by deciphering these intricacies and gaining a thorough understanding of the protein networks and molecular processes in skin. A new window of opportunity has opened up for improving wound healing processes because of recent advancements in skin gene therapy. To enhance skin regeneration and healing, this extensive review investigates the use of novel dressing scaffolds in conjunction with gene therapy approaches. Scaffolds that do double duty as wound protectors and vectors for therapeutic gene delivery are being developed using innovative biomaterials. To improve cellular responses and speed healing, these state-of-the-art scaffolds allow for the targeted delivery and sustained release of genetic material. The most recent developments in gene therapy techniques include RNA interference, CRISPR-based gene editing, and the utilization of viral and non-viral vectors in conjunction with scaffolds, which were reviewed here to overcome skin disorders and wound complications. In the future, there will be rare chances to develop custom methods for skin health care thanks to the combination of modern technology and collaboration among disciplines.

Abstract
Psoriasis presents as a complex genetic skin disorder, characterized by the interaction between infiltrated immune cells and keratinocytes. Substantial progress has been made in understanding the molecular mechanisms of both coding and non-coding genes, which has positively impacted clinical treatment approaches. Despite extensive research into the genetic aspects of psoriasis pathogenesis, fully grasping its epigenetic component remains a challenging endeavor. In response to the pressing demand for innovative treatments to alleviate inflammatory skin disorders, various novel strategies are under consideration. These include gene therapy employing antisense nucleotides, silencing RNA complexes, stem cell therapy, and antibody-based therapy. There is a pressing requirement for a psoriasis-like animal model that replicates human psoriasis to facilitate early preclinical evaluations of these novel treatments. The authors conduct a comprehensive review of various gene therapy in different psoriasis-like animal models utilized in psoriasis research. The animals included in the list underwent skin treatments such as imiquimod application, as well as genetic and biologic injections, and the results of these interventions are detailed. Animal models play a crucial role in translating drug discoveries from the laboratory to clinical practice, and these models aid in improving the reproducibility and clinical applicability of preclinical data. Numerous animal models with characteristics similar to those of human psoriasis have proven to be useful in understanding the development of psoriasis. In this review, the article focuses on RNA-based gene therapy exploration in different types of psoriasis-like animal models to improve the treatment of psoriasis.

Patel V, Mehta TA. Betamethasone Dipropionate Nanocrystals: Investigation, Feasibility and In Vitro Evaluation. AAPS PharmSciTech 2022; 23:197. [PMID: 35835936 DOI: 10.1208/s12249-022-02346-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 06/27/2022] [Indexed: 11/30/2022] Open
Abstract
Corticosteroids, such as betamethasone dipropionate (BMD), have been the mainstay in topical therapy as potent glucocorticoid receptor agonist with immune suppression, anti-proliferative, and anti-inflammatory effects. Moreover, they have poor skin penetration, which is a hurdle against its potential therapeutic benefits. In present investigation, nanocrystals as carrier for effective topical delivery of BMD were explored using wet milling as technique and polysorbate 80 as a non-ionic stabilizer. Upon optimizing different process parameters, promising results were observed at stabilizer concentration of 0.9% w/v having particle size analysis (PSA) and PDI as 284 nm and 0.299, respectively. These results were supported by the FTIR and PXRD spectra of BMD-API and BMD nanocrystals, suggesting strong crystal lattice structure of BMD being reduced due to milling. The reduction in particle morphology was evident from the FESEM images. The optimized batch of BMD nanocrystals was incorporated into Carbopol gel base, showing pH 6.2 ± 0.2 and viscosity 87.00 ± 5.2 Pa s at 25°C. A drug diffusion study using Franz diffusion cell proclaimed around ~86% BMD release from nanogel across the membrane. Also, it was observed that the BMD permeation across the skin was 2.39-fold higher with marketed formulation in contrast to BMD nanogel, suggesting prolonged drug release. The skin permeation flux with nanogel was at a much lower rate along with ~50.27% drug retention in different strata of skin, resulting in retention of drug nanocrystals. Thus, in nutshell the prolonged drug release from nanogel would fulfill the aim of once a day application and would aid in reducing the adverse events associated with repeated drug applications.
