Abstract
Specific critical functions of endocrine and immune cells ensure that an individual remains healthy and free from infection. This study aimed to explore immune–endocrine associations involved in disease. Methods: The PsycINFO, PubMed, Web of Science, and CINAHL databases were searched for relevant articles using the following search terms and phrases: “hormones”, “hormonal responses”, “immune system”, “endocrine system”, “infection”, “immune cells”, “endocrine cells”, “infection”, “immune”, “endocrine”, and “interactions”. The search was limited to articles published between 2009 and 2023. Results: A review of ninety-three studies showed that metabolic activity levels in the body as well as energy consumption patterns are affected by feedback loops that connect the endocrine and immune systems. The associations between endocrine cells and immune cells are complex and involve a wide range of hormones, molecules, and receptors related to antipathogen responses and metabolic regulation. Conclusions: During infection, endocrine cells and immune cells interact via feedback loops to ensure optimal energy utilization and a timely response to pathogens. Therefore, the endocrine system helps to regulate systemic metabolism while controlling the outcomes of regulatory elements of the immune system.
