Macrophages in the pathogenesis of psoriasis and anti-psoriatic nanotherapies

Psoriasis is a common, chronic, and inflammatory skin disease. Macrophages account for about 61.3% of the inflammatory cells infiltrating psoriatic lesions. Modulating macrophage polarization, inhibiting their infiltration, and targeting the secretion of inflammatory factors and associated inflammatory pathways by these cells can alleviate psoriasis symptoms and inflammation. Moreover, nanomaterials as novel drug carriers, offer unique advantages such as large surface area, easy modification, high biocompatibility, good biodegradability, enhanced systemic adsorption, etc. Nanomaterials have great potential for efficient drug delivery and release, as well as improving therapeutic efficacy while reducing adverse effects. By systematically addressing the role of macrophages in psoriasis pathogenesis and the potential of nanomaterials in treating psoriasis through modulating macrophages, this review enhances our understanding of the disease mechanism and holds promise for novel therapeutic breakthroughs and advancements in the future treatment of psoriasis.

Abstract

In the last years, several tissue engineering techniques have been applied to develop different kinds of osteochondral substitutes to overcome the scarce reparative properties of this tissue. The aim of this study was to generate and compare three biphasic scaffolds in an osteochondral lesion in a large-animal model. A critical osteochondral defect was generated in the medial femoral condyle of 18 skeletally mature sheep. Three defects were left untreated, the remaining lesions were divided into three groups: 5 lesions were treated with a biphasic scaffold made of collagen type I and small cylinders of Magnesium Hydroxyapatite; 5 lesions were treated with a biphasic substituted formed by collagen type I and Wollastonite, 5 lesions were treated with a scaffold made of collagen type I and small cylinders of Wollastonite/Hydroxyapatite. Animals were sacrificed after 3 months and samples were analyzed by CT and MRI, macroscopic evaluation and histology. Our study demonstrated that one of these novel biphasic scaffolds possesses the potential for being applied for one-stage procedures for osteochondral defects.
