View full abstract and other project information on NIH RePORTER Go To NIH RePORTER Excerpt: Nicotine at physiologic concentrations impairs macrophage killing of Mycobacterium tuberculosis (MTB), resulting in a 2-5 fold increase in bacterial burden. We have also found that preventing nicotine binding – either pharmacologically or by genetic disruption of the nicotinic receptor – significantly mitigated cigarette smoke extract-induced impairment of macrophage killing of MTB. But the mechanisms by which nicotine impairs macrophage control of MTB are not known. Our hypothesis is that nicot... |
