On January 5th 2006 researchers annouced their studies, they learned that protein p11 plays a key role in depression.
Protein p11 appears to regulate signaling of the brain chemical Serotonin. In so many studies done before Serotonin has been linked with depression and also anxiety disorders. The funny thing is Serotinon is what nearly every anti-depressant is made to regulate, including Prozac.
Whats the difference between protein p11 and Prozac you ask?
Prozac uses compounds called SSRIs, which increase levels of Serotonin in your body. These compounds interact with 14 different serotonin receptors. Prozac stimulates some of the receptors that cause negative side effects, p11 does not interact with these receptors.
So is this the end all cure all?
Maybe, some people react differently, If you do not experience any positive effects from anti-depressants then you can try Paxil. Which aims at the future of antidepressants targeting the 5-HT receptors, which cause very few side effects.
Since p11 is a natural (organic) chemical it can not be patented! Using p11 in future antidepressants will soon be huge. The funds to get such a business started are unknown, but you could do some research and some deep pocket investing to be the first to jump on this market.
