Sarcopenia is one of the most common skeletal muscle disorders and is characterized by infirmity and disability. While extensive research has focused on elucidating the mechanisms underlying the progression of sarcopenia, further comprehensive insights into its pathogenesis are necessary to identify new preventive and therapeutic approaches. The involvement of inflammasomes in sarcopenia is widely recognized, with particular emphasis on the NLRP3 (NLR family pyrin domain containing 3) inflammasome. In this review, we aim to elucidate the underlying mechanisms of the NLRP3 inflammasome and its relevance in sarcopenia of various etiologies. Furthermore, we highlight interventions targeting the NLRP3 inflammasome in the context of sarcopenia and discuss the current limitations of our knowledge in this area.

Prostaglandin E2 (PGE-2) is synthesised by cyclooxygenase-2 (COX-2) and microsomal prostaglandin E synthase 1 (mPGES-1). PGE-2 exhibits pro-inflammatory properties in inflammatory conditions. However, there remains limited understanding of the COX-2/mPGES-1/PGE-2 pathway in Angiostrongylus cantonensis-induced meningoencephalitis.

Department of Orthopedics, The First affiliated Hospital of Hunan University of Chinese Medicine, No. 95 Shaoshan Middle Road, Yuhua District, Changsha City, Hunan Province, 410125, China.

This study aims to assess the safety, efficacy, and mechanisms of Juanbilijieqing Fang in a mouse model of gouty arthritis. C57BL/6 mice were allocated into six groups: control, gouty arthritis model, and treatment groups receiving varying doses of Juanbilijieqing Fang (low, medium, high), along with a positive control group treated with febuxostat. Gouty arthritis was induced via MSU crystal injection following a high-fat diet.

Aim: To explore the neuroprotective effects of high mobility group box 2 () knockdown on retinal ganglion cells (RGCs) in the retinal ischemia-reperfusion injury (RIRI).

Methods: Oxygen-glucose deprivation (OGD)-injured RGCs from postnatal three-day C57BL/6 mice pups and high intraocular pressure (IOP)-induced RIRI mice were used as cellular and animal models of RIRI. The expression of HMGB2 in the retina of RIRI mice and OGD-injured RGCs was detected through reverse transcription-polymerase chain reaction (RT-qPCR) and Western blotting.

The deposition of cholesterol containing cholesterol crystals and the infiltration of immune cells are features of atherosclerosis. Although the role of cholesterol crystals in the progression of atherosclerosis have long remained unclear, recent studies have clarified the involvement of cholesterol crystals in inflammatory responses. Cholesterol crystals activate the NLRP3 inflammasome, a molecular complex involved in the innate immune system.
