Autophagy is an intracellular catabolic pathway essential for the recycling of
proteins and larger substrates such as aggregates, apoptotic corpses, or
long-lived and superfluous organelles whose accumulation could be toxic for
cells. Because of its unique feature to engulf part of cytoplasm in
double-membrane cup-shaped structures, which further fuses with lysosomes,
autophagy is also involved in the elimination of host cell invaders and takes an
active part of the innate and adaptive immune response. Its pivotal role in
maintenance of the inflammatory balance makes dysfunctions of the autophagy
process having important pathological consequences. Indeed, defects in autophagy
are associated with a wide range of human diseases including metabolic disorders
(diabetes and obesity), inflammatory bowel disease (IBD), and cancer. In this
review, we will focus on interrelations that exist between inflammation and
autophagy. We will discuss in particular how mediators of inflammation can
regulate autophagy activity and, conversely, how autophagy shapes the
inflammatory response. Impact of genetic polymorphisms in autophagy-related gene
on inflammatory bowel disease will be also discussed.
