Kiel I totaly see what you're saying about the extracellular environment. What you're saying makes sense.
Help me understand how Moss at Stanford got these results then when giving oral NAC?
"in 18 CF patients with stable disease, blood neutrophils were readily deficient in the pivotal antioxidant glutathione (P = 0.003, compared with 9 healthy controls). In a phase 1 study, <b> this deficiency was improved (P = 0.025) </b> by the glutathione prodrug N-acetylcysteine, given orally in high doses (0.6 to 1.0 g three times daily, for 4 weeks). This treatment was safe and markedly <b> decreased sputum elastase activity (P = 0.006), </b> the strongest predictor of CF pulmonary function. Consistently, <b>neutrophil burden in CF airways was decreased upon treatment (P = 0.003), </b> as was the number of airway neutrophils actively releasing elastase-rich granules (P = 0.005), as measured by flow cytometry. "
Placebo effect?????</end quote></div>
I think gsh is critical in a cells function both internally and externally. So if neutrophils were deficient in GSH and you were to increase it, it would definitely help the overall state of these cells and help them function the way they are suppose to.
However, the problem, i think, is that because of intrinsic defects in GSH transport to the outside of cells OR a gradual depletion of extracellular GSH through sustained infection, that when these white blood cells are releasing Reactive Oxygen Species (ROS...free radicals) to kill invading cells, we don't have enough of the main anti oxidant around to soak up all the harmful crap our immune system is releasing on us.
I think that is a huge reason as well that we are healthier when we are younger. Our anti oxidant stores are higher, and i suppose our nutritional states as well. However, as we get older and live longer with this stress on our body, is starts depleting it of resources that it needs to defend itself. If we don't repelenish the GSH and the vitamins and the amino acids that our immune system needs (it isn't meant for a prolonged period of activation), then it messes us up, basically.
I hope this made sense. It's 9 am and i just got home from my overnight shift...
