Influenza infection rewires energy metabolism and induces browning features in adipose cells and tissues


ABSTRACT: Influenza A viruses cause epidemics and pandemics with damaging health and economic impacts. Alike any obligate intracellular pathogen, IAVs hijack host cell machinery and energetic resources to multiply within, and eventually exit, the host. Increased fatty acid and cholesterol synthesis, as well as increased glucose metabolism have been identified as the major metabolic changes induced by infection. Besides these effects on metabolism, IAV infection also triggers a variety of innate defense mechanisms within the host cell. Although mainly defined as a virus of the respiratory tract, with airway epithelial cells being its prime cellular habitat, complications outside the site of infection have also been reported. However, whether influenza on its own may impact on endocrine tissues and, thereby, lead to metabolic complications, has never been investigated. Here, we compared the response of preadipocytes and adipocytes to IAV infection, in terms of transcriptomic profiles and bioenergetics. The results showed that IAV triggers a browning adipogenesis process, leading to metabolic reprogramming of the adipose tissue resulting in long-lasting alterations of body metabolism. We conclude that the adipose tissue might be an undervalued organ in influenza pathophysiology.
