  Interleukin - Wikipedia, the free encyclopedia
Interleukins are a group of cytokines (secreted signaling molecules) that were first seen to be expressed by white blood cells (leukocytes, hence the -leukin) as a means of communication (inter-).
The name is something of a relic though; it has since been found that interleukins are produced by a wide variety of bodily cells.
The function of the immune system depends in a large part on interleukins, and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency.

 Interleukin 6 - Wikipedia, the free encyclopedia
IL-6 is probably the best studied of the cytokines that use gp130 in their signalling complexes.
Other cytokines that signal through receptors containing gp130 are Interleukin 11 (IL-11), Interleukin 27 (IL-27), ciliary neurotrophic factor (CNTF), cardiotrophin-1 (CT-1), cardiotrophin-like cytokine (CLC), leukemia inhibitory factor (LIF), oncostatin M (OSM), Kaposi's sarcoma associated herpes virus interleukin 6 like protein (KSHV-IL6).
These cytokines are commonly referred to as the IL-6 like or gp130 utilising cytokines.

Carpagnano and colleagues (1) recently reported in CHEST (October 2002) a significant increase in 8-iseprostane and interleukin (IL)-6 levels in the exhaled breath condensate of obstructive sleep apnea (OSA) patients compared with that of obese subjects.

Interleukin 6 (IL-6) is thought to play important roles in the development of reactive thrombocytosis caused by inflammation by its stimulatory effect on megakaryocytopoiesis.
In fact, circadian interrelationships among levels of plasma fibrinogen, blood platelets and serum interleukin 6 have been recently reported [11].
Although basal interleukin 6 levels were not statistically different between genotypes in this report (p = 0.07), the study of circadian IL-6 levels will shed light on differences of transcription rate attributed to IL-6 gene polymorphism.

Body temperature normally fluctuates over the day, with the lowest levels at 4 A.M. and the highest at 6 P.M. Therefore, an oral temperature of 37.5°C would strictly be a fever in the morning, but not in the afternoon.
The endogenous pyrogens (such as interleukin 1) are a part of the innate immune system, produced by phagocytic cells, and cause the increase in the thermoregulatory set-point in the hypothalamus.
This binding results in the synthesis and release of various cytokine factors, such as interleukin 1 (IL-1), interleukin 6 (IL-6), and the tumor necrosis factor-alpha.
