Pseudogenes clearly play an active role in regulating chronic inflammation in humans, a key cellular process that is associated with cancer, autoimmune disorders and cardiovascular and neurodegenerative diseases. (icr.org)
3 The chronic inflammation of tissues in the human body is a key feature related to diseases associated with autoimmune responses, cardiovascular disorders, and neurodegenerative conditions. (icr.org)
Inflammation is a normal response to attacks detected by the immune system, such as from bacteria, viruses, harmful chemicals and even cancer cells. (icr.org)
The process involving inflammation is a protective attempt by the body to halt the attack and remove the offending stimuli from the system, thus initiating the natural healing process. (icr.org)
Because this response can only be carried out temporarily, it must be tightly regulated-inflammation must be scaled back once the attack is over or chronic inflammation can occur. (icr.org)
This indicated that different groups of pseudogenes have unique functions in the immune response, and that the general observation of pseudogene activity in inflammation was considerably more complicated and specifically coordinated. (icr.org)
The research and its results not only showed how large groups of pseudogenes were involved in the inflammation response, but also allowed for the specific targeting of some of them to determine their function. (icr.org)
One such pseudogene that was targeted for study, was named 'Lethe,' which turned out to be a master regulator of the inflammation response-turning it off when it was no longer needed. (icr.org)
Thus, one of the key regulatory switches in the genome that keeps inflammation in check, is a pseudogene! (icr.org)
