Consequently, -cells synthesize both DA and NE de novo, though preferentially produce DA in response to uptake of precursor L-DOPA
With Travis Craddock and Nancy Klimas uncovering evidence of a possible genetic vulnerability in the mucous membranes of the nose which could potentially explain much in ME/CFS, the nose is becoming an ever more interesting place (blog coming up.) If youve tried intranasal preparations of glutathione, insulin or another substance, please let us know how it went.
Scientists hope that with further development, stem cell therapy could become widely available, offering a permanent, non-invasive cure for a condition that affects hundreds of millions globally
Missing links in understanding redox signaling via thiol/disulfide modulation: How is glutathione oxidized in plants
However, excessive accumulation of GSH precursors can overwhelm this reducing capacity, leading to reductive stress and aberrant mitochondrial H 2 O 2 production, a mechanism that is particularly pronounced in cancer cells characterized by elevated cysteine metabolism but limited antioxidant enzyme capacity 209
