A link was found by researchers between cigarette smoking and type 2 diabetes.

Swedish scientists have found new evidence of beta cells and their ability to secrete insulin. The findings suggest that smokers may be more prone to contracting type 2 diabetes. The study was published in the journal Cell Reports.

The nicotine sensitive receptors in the brain were influencing the release of insulin. A certain gene caused the nicotine receptors to lose their sensitivity thereby also decreasing the receptors in the beta cells of the pancreas.

This automatically led to a decrease in insulin production and a chance of contracting type 2 diabetes. Normally acetylcholine is involved in the signaling of the beta cells of the pancreas.

However, nicotine plays a part in this process as well. This link between nicotine and beta cells has never been shown before. Those who lack the receptors are at more of a risk of becoming type 2 diabetics.

The gene responsible for this scheme of things is none other than MafA (which stands for musculoaponeurotic fibrosacoma oncogene family A).

This gene is found in the beta cells. It controls the nicotine sensitive receptors. As they receive signals from the CNS, they go to work and the results are obvious.

The discovery of this gene is a game changer. Before this, nothing was known of the link between smoking and type 2 diabetes. Now though it seems the scientists have discovered something of lasting importance.

Smokers may lose their customary ten pounds by starting the unhealthy habit but they are not doing themselves any favors whatsoever. Their chances of contracting type 2 diabetes also grows proportionately as they take to the “cancer stick”.

Genes play an important role in the human body. There are so many of them that merely beginning to list them is the most hectic process. Still discoveries are being made of new genes and gene markers.

With the finding of MafA, a whole new chapter in the prevention and treatment of diabetes may have begun. The why and wherefore of the diabetes-nicotine connection remains a mystery.

What inner machinations are at work remain to be figured out. What we do know with certainty is that smoking is a bad habit and may cause several more problems than just a chance of ending up in a cancer ward.
