Adiponectin (ADPN), a hormone predominantly secreted by adipose tissue, plays a critical role in regulating glucose metabolism, fatty acid oxidation, and insulin sensitivity. Structurally, it exists in multiple oligomeric forms (low-molecular-weight trimers, hexamers, and high-molecular-weight multimers) that exhibit distinct biological activities. ADPN binds to receptors AdipoR1 and AdipoR2. activating downstream pathways like AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor-alpha (PPAR-α), which improve metabolic homeostasis.
Low circulating ADPN levels are strongly associated with obesity-linked disorders, including type 2 diabetes, cardiovascular diseases, and non-alcoholic fatty liver disease (NAFLD). This correlation has driven interest in recombinant ADPN (rADPN) as a therapeutic candidate. Recombinant production systems (e.g., *E. coli*, mammalian cells) enable scalable synthesis of functional ADPN variants. However, challenges persist in mimicking post-translational modifications (e.g., hydroxylation, glycosylation) critical for its stability and receptor-binding efficiency.
In preclinical studies, rADPN administration has demonstrated anti-diabetic, anti-inflammatory, and cardioprotective effects, restoring insulin sensitivity and reducing atherosclerotic plaque formation. Researchers also explore engineered ADPN analogs or receptor agonists to overcome pharmacokinetic limitations, such as short half-life and rapid clearance. Despite hurdles in clinical translation, rADPN remains a promising tool for elucidating metabolic regulation mechanisms and developing targeted therapies for metabolic syndrome-related conditions. Ongoing efforts focus on optimizing production techniques, enhancing bioavailability, and evaluating long-term safety profiles in human trials.
