Research Article: Amygdalin Delays Cartilage Endplate Degeneration and Improves Intervertebral Disc Degeneration by Inhibiting NF-?B Signaling Pathway and Inflammatory Response

Date Published: 2023-08-14

Abstract:
Low back pain (LBP) is one of the common orthopaedic diseases in daily life, and its prevalence is increasing with age, and it is also related to excessive exercise., This not only affects people’s quality of life but also increases the burden of social medical resources. As research has found, disc degeneration is closely linked to LBP and is one of the main causes of LBP. However, the exact mechanism of Intervertebral disc degeneration (IDD) has not yet been elucidated. The intervertebral disc (IVD) is a fibrocartilaginous disc between two adjacent pyramids, consisting of the nucleus pulposus (NP), the annulus fibrosus (AF), and the upper and lower cartilage endplates (CEP). Modern studies have found that IDD is mainly manifested in the reduction of the number of NP cells, abnormal ECM metabolism, reduction of type II collagen, and calcification and death of endplate chondrocytes, etc. Nowadays, the therapeutic strategies to treat IVD degeneration and assuage IDD-related pain include conservative treatments, such as anti-inflammatory drugs. When these treatments prove themselves inefficient, radical surgical interventions (eg disc removal and spinal fusion) are considered. These changes are closely related to the inflammatory response mediated by cellular inflammatory factors. Inflammation not only reduces the synthesis of extracellular matrix such as proteoglycans and type II collagen but also promotes the expression of matrix metalloproteinases (MMPs), which further reduces the biological properties of cartilage endplates and eventually leads to IDD.– For example, administration of Chlorogenic Acid (CGA) mitigated cartilaginous endplate degeneration and postponed IDD development accompanying a decrease of inflammatory and catabolic mediators.
