What I do

Research on nitric oxide physiology supporting my discovery that commensal ammonia oxidizing bacteria can live on the skin as a biofilm and metabolizing ammonia in sweat into NO and nitrite.

By doing so, they set the basal level of NO/NOx.

Interests

NO physiology: In particular how NO is used as a regulatory molecule, and how because each NO sensor only senses the sum of NO from all NO sources, a change in the basal level of NO affects the operating point of all NO regulated pathways with no threshold (that is, any change in the basal NO level affects the output).

Important NO mediated pathways: include mitochondria biogenesis, the ATP setpoint, steroid synthesis, bone density, vascular tone, O2 consumption by cytochrome c oxidase, metallization of Zn finger proteins, to name a few. All these pathways are characteristically affected with no threshold by changes in basal NO. It is a shift in setpoint and not dysregulation.

All NO pathways are coupled, because NO from all sources is summed to produce an effect. There is cross-talk between all NO pathways. This is why NO therapies are so difficult (due to side effects) and why (I think) many seemingly disparate disorders have symptoms that are so similar.

Projects
