Interleukins are a vital part of the pathway that regulates inflammation in the body. There are many different types of interleukins.
Interleukins play a key role in the development or progression of inflammatory conditions.
Inflammation and Interleukins. Inflammation (Latin, inflammatio, to set on fire) is the complex biological response of vascular tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. It is a protective attempt by the organism to remove the injurious stimuli as well as initiate the healing process for the tissue. Inflammation is not a synonym for infection. Wikipedia.
