Slavin, Y.N. Another cause of AMR is the poor pharmacokinetics of many classical drugs, due to difficulty in reaching the site of action; as a result, subcellular niches used by infecting bacteria are not reached by most current drugs. 1) Chloride ions are pumped into the epithelial cell causing a concentration gradient and the CFTR channel protein opens 2) Chloride ions diffuse into the mucus through the CFTR protein 3) This closes the ENaC 4) The build up of chloride ions creates an electrical gradient so sodium ions diffuse into the mucus between the gaps in epithelial cells It affects organs in the body, particularly the lungs and digestive system, which become clogged with sticky mucus, making it difficult to breathe and digest food.

In a healthy person, the pancreas produces chemicals (enzymes) which pass into the gut as food leaves the stomach. About 70% of mutations observed in CF patients result from deletion of three base pairs in CFTR's nucleotide sequence.

In a healthy person, the pancreas produces chemicals (enzymes) which pass into the gut as food leaves the stomach. Immunocompromised individuals and cystic fibrosis patients are especially vulnerable to serious infections by these bacteria, motivating the search for compounds with antimicrobial activity against the Bcc. As a result, delta F508 never reaches the cell membrane. Intracellular pathogens evolved to infect, colonise, and duplicate within host cells, managing to hide from the host immune system [, This lack of appropriate classical therapies has different causes, including antimicrobial resistance (AMR) which could have several mechanisms, such as the misuse of antimicrobials in both the healthcare and veterinary sectors.
