[, Therefore, being as this preliminary evidence very promising, it is advisable to continue to study the use of NO as an alternative strategy to treat, Phage therapy (PT) represents an old idea which has acquired renewed importance thanks to the successful recent case reports, where antibiotic-resistant lung infections in CF people were treated [, PT refers to the use of phages to fight bacterial infections. Brogden, K.A. With normal CFTR, once the protein is synthesized, it is transported to the endoplasmic reticulum (ER) and Golgi apparatus for additional processing before being integrated into the cell membrane.
