 Compounds in cigarettes have been said to be carcinogenic. As discussed in [[home:publications:proal_autoimmunity_2010|Amy Proal's presentation at the 2010 International Congress on Autoimmunity]], Sapkota //et al.// identified fifteen different classes of bacteria and a broad range of pathogenic organisms in five commonly smoked cigarettes tested.(({{pubmed>long:20064769}})) That said, the underlying disease process by which smoking is said to cause death is not well-defined.
-===== Smoking and prolonged stress decrease production of antimicrobial peptides =====
-Smoking and prolonged stress have been linked to increased susceptibility to bacterial infection. A 2010 study appearing in //Cell Host and Microbe// shows that this may be caused by a decrease in antimicrobial peptide (AmP) activity as a result of increased stimulation of a neuroendocrine signalling pathway.(({{pubmed>long:20413096}})) Radek //et al.// showed that when nicotinic acetylcholine receptors (nAChRs) were stimulated, mice had decreased AmP production and were increasingly susceptible to the pathogens methicillin-resistant //Staphylococcus aureus// and Group A //Streptococcus// infections.

+  * **Nicotine interferes with apoptosis** – According to a 2007 review, nicotine acts on immune cells. Although nicotine itself is usually not referred to as a carcinogen, there is ongoing debate whether nicotine functions as a "tumor enhancer." By binding to nicotinic acetylcholine receptors, nicotine deregulates essential biological processes like angiogenesis, apoptosis, and cell-mediated immunity.(({{pubmed>long:17846896}})) Delayed apoptosis – that is, the inability of cells to self-destruct – is one of the hallmarks of chronic inflammatory disease. It is well-documented that microbes induce delayed apoptosis in order to gain a survival advantage.
