Adiponectin is classified as a protective cytokine because it plays a key role in regulating metabolic processes, particularly in the context of obesity and insulin sensitivity. It is secreted by adipose tissue and has anti-inflammatory properties, helping to reduce the risk of various metabolic disorders such as type 2 diabetes and cardiovascular disease. Adiponectin enhances insulin sensitivity, promotes fatty acid oxidation, and is involved in glucose regulation, thereby contributing to overall metabolic health.

In contrast to the other classifications, adiponectin’s protective role is significant in mitigating inflammation and promoting a healthy metabolic state, differentiating it from inflammatory cytokines, which would typically contribute to inflammatory processes. While it does have some growth factor-like properties, its primary function aligns more closely with that of a protective cytokine. It is not classified as a stress hormone; instead, it is secreted in response to metabolic changes rather than stressors.
