Therapeutic blockade of CCL17 in obesity-exacerbated osteoarthritic pain and disease.

Objectives: We previously reported that CCL17 gene-deficient mice are protected from developing pain-like behaviour and exhibit less disease in destabilization of medial meniscus (DMM)-induced OA, as well as in high-fat diet (HFD)-exacerbated DMM-induced OA. Here, we explored if therapeutic neutralization of CCL17, using increasing doses of a neutralizing monoclonal antibody (mAb), would lead to a dose-dependent benefit in these two models.

Design: DMM-induced OA was initiated in male mice either fed with a control diet (7% fat) or 8 weeks of a 60% HFD, followed by therapeutic intraperitoneal administration (i.

The promising approach of 3D bioprinting for diabetic foot ulcer treatment: A concise review of recent developments.

Diabetic foot ulcer (DFU), one of the most significant complications of diabetes, is a condition that causes anatomical and functional alterations of the foot resulting in an important social and economic impact, related to disability and health care costs. Recently, three-dimensional bioprinting - which allows the fabrication of complex and biocompatible structures - has been identified as a promising approach in the field of regenerative medicine to promote the healing of chronic wounds, such as DFU. In this concise review we highlight the most relevant and recent attempts of using 3D bioprinted constructs - both on animals and people - in order to treat non-healing diabetic ulcers and prevent their worsening.

An Updated Review of the Marine Ornamental Fish Trade in the European Union.

Wild-caught fish from coral reefs, one of the most threatened ecosystems on the planet, continue to supply the marine aquarium trade. Despite customs and veterinary checks during imports, comprehensive data on this global industry remain scarce. This study provides consolidated data on the largest import market by value, the European Union (EU): a 24-million-euro annual trade value, detailing the main exporting and importing countries, as well as the species and families of the 26 million specimens imported between 2014 and 2021.

The GM-CSF/CCL17 pathway in obesity-associated osteoarthritic pain and disease in mice.

Objectives: We have previously identified a granulocyte macrophage-colony stimulating factor (GM-CSF)/C-C motif ligand 17 (CCL17) pathway in monocytes/macrophages, in which GM-CSF regulates the formation of CCL17, and it is important for an experimental osteoarthritis (OA) model. We explore here additional OA models, including in the presence of obesity, such as a requirement for this pathway.

Design: The roles of GM-CSF, CCL17, CCR4, and CCL22 in various experimental OA models, including those incorporating obesity (eight-week high-fat diet), were investigated using gene-deficient male mice.
