Cordycepin benefit and review of studies
Cordyceps militaris, a traditional medicinal mushroom, produces a component compound, cordycepin (3'-deoxyadenosine). Cordycepin has been known to have many pharmacological activities including immunological stimulating, anti-cancer, and anti-infection activities.

It has been recently noticed that type 2 diabetes (T2D), one of the most common
metabolic diseases, causes a chronic low-grade inflammation and activation of
the innate immune system that are closely involved in the pathogenesis of T2D.
In the present study, we tested the role of cordycepin on the anti-diabetic
effect and anti-inflammatory cascades in LPS-stimulated RAW 264.7 cells. We
confirmed the levels of diabetes regulating genes mRNA and protein of cytokines
through RT-PCR and western blot analysis and followed by FACS analysis for the
surface molecules. Cordycepin inhibited the production of NO and
pro-inflammatory cytokines such as IL-1beta, IL-6, and TNF-alpha in
LPS-activated macrophages via suppressing protein expression of pro-inflammatory
mediators. T2D regulating genes such as 11beta-HSD1 and PPARgamma were decreased
as well as expression of co-stimulatory molecules such as ICAM-1 and B7-1/-2
were also decreased with the increment of its concentration. In accordance with
suppressed pro-inflammatory cytokine production lead to inhibition of diabetic
regulating genes in activated macrophages. Cordycepin suppressed NF-kappaB
activation in LPS-activated macrophages. Based on these observations, cordycepin
suppressed T2D regulating genes through the inactivation of NF-kappaB dependent
inflammatory responses and suggesting that cordycepin will provide potential use
as an immunomodulatory agent for treating immunological diseases.
